UV absorber UV-327: Invisible guardian of high-end plastic products

In modern society, plastic products have become an indispensable part of our daily lives. From mobile phone cases to car dashboards, from food packaging to medical devices, plastics occupy an important position in various fields for their lightness, durability and economical characteristics. However, while enjoying these conveniences, we also face a problem that cannot be ignored – the erosion effect of ultraviolet rays on plastics. The ultraviolet rays in the sun are like an invisible knife, quietly weakening the strength of the plastic, changing its color, and even making it fragile and brittle. This phenomenon not only affects the appearance and service life of the product, but may also bring safety hazards.

It is in this context that the ultraviolet absorber UV-327 came into being. It is a high-performance ultraviolet protection additive, specially used to improve the durability and stability of plastic products in ultraviolet environments. UV-327 effectively prevents the destruction of UV rays from plastic molecular chains by capturing and converting UV energy into harmless thermal energy or chemical bond vibrations. This “hero behind the scenes” not only extends the life of plastic products, but also ensures the sustained and stable performance. Whether it is billboards for outdoor use or automotive parts that require long-term exposure to the sun, the UV-327 can provide excellent protection and become an indispensable “invisible shield” for high-end plastic products.

This article will deeply explore the mechanism of action, scope of application and market prospects of UV-327, and demonstrate its importance in modern industry through rich data and case analysis. Let us uncover the mystery of this star material in the field of plastic protection.

Basic Characteristics and Principles of UV-327

Chemical structure and physical properties

UV absorber UV-327 (chemical name: 2-(2′-hydroxy-5′-methylphenyl)benzotriazole) is a light stabilizer widely used in plastics and other polymer materials. Its chemical structure contains benzotriazole rings, a feature that imparts strong UV absorption capacity to UV-327. Specifically, the molecular formula of UV-327 is C15H11NO2 and the molecular weight is 241.26 g/mol. Its appearance is usually white to light yellow powder with melting points ranging from 108°C to 112°C, with good thermal and chemical stability. In addition, the density of UV-327 is about 1.3 g/cm³, and has low solubility. It is mainly suitable for organic solvent systems, such as alcohols and ester solvents.

Method of action

The core function of UV-327 is to absorb UV and convert it into harmless energy forms, thereby avoiding the damage to the plastic molecular chains by UV. This process can be divided into the following key steps:

  1. Ultraviolet capture
    When ultraviolet rays irradiate on the plastic surface containing UV-327, the benzotriazole ring in the UV-327 molecule preferentially absorbs ultraviolet rays with wavelengths ranging from 290nm to 400nm. This wavelength range is the part that has a great impact on plastic aging. By absorbing ultraviolet rays, UV-327 effectively blocks the possibility that ultraviolet rays can penetrate directly into the plastic interior.

  2. Energy Conversion
    After absorbing ultraviolet rays, UV-327 molecules enter an excited state. It then releases the absorbed energy in the form of thermal energy through non-radiative transitions, or consumes excess energy through intramolecular vibrations. This process not only avoids the direct damage to the plastic molecular chain by ultraviolet rays, but also ensures the stability of UV-327 itself and will not decompose or fail due to excessive absorption.

  3. Prevent free radical formation
    Ultraviolet-induced photooxidation reactions usually cause the plastic molecular chain to break and form free radicals. These free radicals further participate in the chain reaction, accelerating the aging process of plastics. UV-327 absorbs ultraviolet rays, reducing the chance of photooxidation reactions, thereby indirectly inhibiting the generation of free radicals and delaying the aging process of plastics.

Feature Advantages

The reason why UV-327 can become the first choice for high-end plastic products is closely related to its unique characteristics:

Features Description
Efficient absorption Can absorb ultraviolet rays with a wide wavelength range and cover key areas from 290nm to 400nm.
Thermal Stability Stay stable at processing temperature and is not easy to decompose or volatilize.
Chemical Inert No adverse reactions with plastic substrates or other additives, and have strong compatibility.
Anti-mobility It is not easy to migrate from the plastic surface to the external environment, ensuring long-term effectiveness.

To sum up, UV-327 has become an indispensable light stabilizer in the plastics industry with its superior chemical structure and mechanism of action. Next, we will further explore the performance of UV-327 in different application scenarios and its significant advantages.

Application of UV absorber UV-1 in UV-1 for UV protection treatment in textiles

Introduction: “Love, Hate, Love and Hate” with the Sun

The Sun, the superstar on the cosmic stage, brings warmth and energy to the earth with its blazing light every day. However, it is not always so “friendly”. In the sun, there is an invisible but ubiquitous “invisible killer” – Ultraviolet Radiation (UV). Although moderate amounts of ultraviolet rays are beneficial to human health, such as promoting the synthesis of vitamin D, excessive exposure can lead to serious consequences such as skin aging, sunburn and even cancer. Therefore, how to effectively protect ultraviolet rays has become an important topic in modern life.

As the main material for people to wear in daily life, textiles are directly related to the health and safety of the human body. However, natural fibers such as cotton and linen have limited barrier ability to ultraviolet rays, and although chemical fibers have a certain shielding effect, they are prone to deterioration after long-term use, and the protective effect is reduced due to aging. Therefore, scientists have turned their attention to the magical chemical product of ultraviolet absorbers. Among them, UV absorber UV-1 has become an important choice in the field of UV-proof treatment for textiles due to its excellent performance and wide application prospects.

This article will conduct in-depth discussions on the ultraviolet absorber UV-1, and conduct a comprehensive analysis from its basic principles, product parameters, application methods to the current research status at home and abroad. Through rich tabular data and literature references, we will reveal to you how this small molecule plays a great role in textiles. Let us enter this world full of technological charm together!

The basic principles of UV absorber UV-1

To understand the working mechanism of the UV absorber UV-1, we first need to understand the nature of UV and how it harms the human body. Ultraviolet rays are electromagnetic radiation with a wavelength range of 100 to 400 nanometers and are divided into three main parts: UVA (320-400 nm), UVB (290-320 nm) and UVC (100-290 nm). Among them, UVC is almost completely absorbed by the atmosphere, while UVA and UVB are the culprits that reach the surface and affect human health.

Hazards of UV rays

UVA is called “light of aging” because it can penetrate the dermis, destroy collagen and elastic fibers, causing problems such as skin sagging, wrinkles and pigmentation. UVB is called “burning light”. It has higher energy and mainly acts on the epidermis, causing redness, swelling, pain and even cell mutations. Long-term exposure may induce skin cancer.

So, how does UV absorber UV-1 protect us from these hazards? The answer lies in its molecular structure and functional characteristics.

Mechanism of action of UV absorber UV-1

UV-1 is a benzotriazole compound, with the chemical name 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. Its molecular structure contains a key aromatic ring system, which gives UV-1 strong ultraviolet light absorption capacity. Specifically, when UV rays hit the surface of a textile containing UV-1, UV-1 quickly captures the energy of UV and converts it into heat or harmless low-energy radiation to release it, thereby avoiding UV rays from penetrating the fabric and causing damage to the skin.

This transformation process can be vividly compared to a “energy relay race”. Imagine UV rays are like a bunch of naughty balls trying to break into our skin castle. The UV-1 is like a well-trained goalkeeper, steadily catching every little ball and then skillfully transferring them elsewhere so that they can no longer threaten the safety of the castle.

In addition, UV-1 also has good light resistance and stability, and can maintain high UV protection performance even after multiple washings or long exposure to the sun. This makes it an ideal choice for UV protection for textiles.

Product parameters of UV absorber UV-1

In order to better understand the performance characteristics of UV-1, we need to conduct detailed analysis of its various parameters. The following is a table that provides a comprehensive description of UV-1 in terms of appearance, solubility, stability and scope of application:

parameter name Description
Appearance White or slightly yellow powder, no special odor
Molecular formula C15H11N3O
Molecular Weight 253.27 g/mol
Solution Slightly soluble in water, easily soluble in, etc.
Heat resistance Can withstand high temperatures up to 280? without decomposition
Photostability Express excellent stability under strong ultraviolet light and is not prone to photodegradation
Chemical Stability It has strong tolerance to acid and alkali environment, and the pH adaptation range is 4-10
Large absorption wavelength 340-360 nm, covering UVA and some UVB bands
Application concentrationRange It is usually recommended that the amount of addition is 0.5%-2% of the weight of the textile. The specific amount should be adjusted according to the type of fabric and requirements

From the table above, UV-1 not only performs excellent in physical properties, but also exhibits extremely high reliability and flexibility in chemical properties. Whether it is used for light and breathable summer clothing or heavy and warm winter jackets, the UV-1 provides excellent UV protection.

Application method of UV absorber UV-1 in textiles

The successful application of UV-1 to textiles is not an easy task, but a process that requires a combination of scientific formulas and exquisite craftsmanship. The following are several common application methods and their advantages and disadvantages:

Method 1: Immersion method

Operation steps

  1. Dissolve UV-1 in a certain proportion in an appropriate solvent to make a working liquid;
  2. Immerse the textiles completely into the working liquid to ensure uniform adsorption;
  3. The textiles were extracted and dried to allow UV-1 to adhere firmly to the fiber surface.

Pros

  • Simple process and easy to achieve large-scale production;
  • The cost is low and suitable for handling large batches of ordinary textiles.

Disadvantages

  • The protective effect may gradually weaken over time;
  • It may have adverse effects on certain special materials (such as wool, silk).

Method 2: Coating method

Operation steps

  1. Mix UV-1 with other additives to form a stable coating solution;
  2. Use spraying, brushing or rolling coating to apply the coating evenly to the surface of the textile;
  3. After curing treatment, a dense protective film is formed.

Pros

  • Last protection effect and strong anti-washing ability;
  • The coating thickness can be adjusted according to needs to achieve personalized customization.

Disadvantages

  • Complex process and high cost;
  • May affect the feel and breathability of textiles.

Method 3: Blending Spinning Method

Operation steps

  1. UV-1 is directly added to the raw material during spinning to disperse it evenly;
  2. Make functional fibers and then wove them into fabric.

Pros

  • The protective effect is embedded in the fiber and will not fail due to external factors;
  • Environmentally friendly and energy-saving, reducing subsequent processing processes.

Disadvantages

  • The technical difficulty is high and the equipment investment is high;
  • Applicable only to specific types of textiles.

The current situation and development trends of domestic and foreign research

With people’s awareness of ultraviolet protection, the research and application of the ultraviolet absorber UV-1 has received widespread attention. The following is a summary of some research results of domestic and foreign scholars in this field in recent years:

Domestic research progress

A study by a research institute of a Chinese Academy of Sciences shows that by optimizing the dispersion technology of UV-1, its uniform distribution in textiles can be significantly improved, thereby improving the overall protective effect. Experimental data show that the UPF value (ultraviolet protection coefficient) of textiles after using improved processes can reach 50+, far exceeding the requirements of international standards.

Another study led by Tsinghua University focuses on the composite application of UV-1 and nanomaterials. Researchers found that using UV-1 with titanium dioxide nanoparticles can not only enhance the UV absorption capacity, but also impart a variety of additional functions such as antibacterial and self-cleaning to textiles.

International Research Trends
