Working principle and mechanism to reduce harmful gas emissions

The low-odor reactive 9727 can perform well in reducing harmful gas emissions mainly due to its unique chemical reaction mechanism and material design. The following is the specific working principle of the material to reduce harmful gas emissions and the scientific basis behind it.

1. Relationship between curing reaction and VOCs generation

The curing process of the low-odor reaction type 9727 is achieved through the chemical reaction between the polymer and the crosslinking agent. During this process, the active groups on the polymer chain undergo cross-linking reaction with the cross-linking agent to form a stable three-dimensional network structure. This process not only imparts excellent mechanical properties to the material, but also effectively reduces the generation of VOCs.

During the curing process, traditional polymer materials often release a large number of volatile organic compounds (VOCs). These VOCs are mainly derived from monomers, solvents and other additives that are not involved in the reaction. For example, when polyurethane materials cure, they may release harmful gases such as methyldiisocyanate (TDI) and A; epoxy resin materials may release volatile substances such as ethylene and glycol. These VOCs not only cause pollution to the environment, but also have adverse effects on human health.

In contrast, the low-odor reaction type 9727 uses efficient crosslinking agents and catalysts, making the curing reaction more thorough and reducing the residues of unreacted monomers and additives. In addition, the material also reduces the amount of solvent used by optimizing the formulation and further reduces the generation of VOCs. Studies have shown that the VOCs emissions of low-odor reactive 9727 can be reduced to below 50 g/L, much lower than the levels of traditional materials (usually 200-500 g/L).

2. Odor suppression technology

In addition to reducing the generation of VOCs, the low-odor reactive type 9727 also adopts advanced odor suppression technology, which effectively reduces the odor generated by the material during curing and use. The source of odor mainly includes the following aspects:

  • Unreacted monomer: During the curing process, some monomers fail to react completely and remain in the material, resulting in the generation of odor.
  • By-products: Some chemical reactions will produce by-products, such as amines, aldehydes, etc., which often have a strong odor.
  • Addants: Some functional additives, such as plasticizers, antioxidants, etc., may also decompose at high temperatures and release odors.

In order to suppress these odors, the low-odor reaction type 9727 uses a variety of technical means:

  • High-efficiency Catalyst: By selecting the appropriate catalyst, the curing reaction speed is accelerated, the residue of unreacted monomers is reduced, thereby reducing the generation of odors.
  • Odor adsorbent: Adding special odor adsorbents, such as activated carbon, molecular sieve, etc. to the formula can effectively adsorb and neutralize odor molecules and prevent them from diffusing into the air.
  • Low Odor Aid: Use low-odor or odorless additives to replace traditional high-odor aids to fundamentally reduce the source of odor.

According to foreign literature reports, after using odor suppression technology, the odor level of the low-odor reaction type 9727 can reach level 1 (almost odorless), which is significantly better than similar products on the market. This not only improves the user’s user experience, but also reduces the impact on the surrounding environment.

3. Low toxicity design

The low-odor reaction type 9727 is designed to fully consider the safety and environmental protection of the material and avoid the use of harmful substances. Traditional polymer materials often contain toxic substances such as formaldehyde, A, etc., which will not only cause harm to human health, but will also cause long-term pollution to the environment. To this end, the low-odor reaction type 9727 adopts the following measures:

  • Nontoxic Monomers: Choose non-toxic or low-toxic monomers as raw materials, such as aqueous polyurethanes, aqueous epoxy resins, etc., and avoid using traditional monomers containing formaldehyde and other harmful substances.
  • Environmental Solvent: Use aqueous solvents or low-volatile organic solvents to replace traditional organic solvents and reduce VOCs emissions.
  • Heavy metal-free catalysts: Choose heavy metal-free catalysts, such as titanium esters, organic amines, etc., avoid using heavy metal-containing catalysts such as lead and mercury, and reduce pollution to the environment.dye.

After testing by a third-party organization (such as SGS), the low-odor reaction type 9727 does not contain formaldehyde or other harmful substances, and complies with the GB 18583-2008 “Limited amount of hazardous substances in adhesives for interior decoration materials”, ensuring the safety of the material and environmentally friendly.

4. Multi-level protection mechanism

The low-odor reaction type 9727 not only pays attention to environmental protection in the design of the material itself, but also provides a multi-level protection mechanism during construction and use to ensure that the emission of harmful gases is effectively controlled. Specific measures include:

  • Confined Construction Environment: During the construction process, it is recommended to use a closed construction environment and equip ventilation equipment to promptly discharge a small amount of VOCs generated during the construction process to avoid affecting the construction personnel and the surrounding environment.
  • Surface treatment: After the material is cured, the release of VOCs can be further reduced by applying a protective film or performing surface treatment. Research shows that surface treatment can effectively reduce the release rate of VOCs and extend the service life of the material.
  • Regular maintenance: For products that have been used, it is recommended to regularly maintain and clean the surface of the material to maintain the integrity and stability of the material and prevent the release of VOCs caused by aging and degradation.

Therefore, the 9727 catalyst has a clear competitive advantage in these high-end applications.

9727 Reaction Mechanism of Catalyst

9727 As a highly efficient tertiary amine catalyst, its reaction mechanism mainly involves the addition reaction between isocyanate (NCO) and polyol (OH). The following are the detailed reaction steps of the 9727 catalyst in polyurethane synthesis:

1. Initial reaction of isocyanate with polyol

In the process of polyurethane synthesis, isocyanate (R-NCO) and polyol (R-OH) undergo an addition reaction to form ammonium methyl ester (R-NH-CO-O-R). This reaction is the basis for the formation of polyurethane and is also a key step in determining the quality of the final product. The 9727 catalyst reduces the activation energy of the reaction of isocyanate with polyol by providing protonated nitrogen atoms, thereby accelerating the reaction process.

[ R-NCO + R’-OH xrightarrow{9727} R-NH-CO-O-R’ ]

2. Protonation of catalyst

9727 The tertiary amine group in the catalyst can form hydrogen bonds with the carbonyl oxygen atoms in isocyanate, increasing the electron cloud density of the isocyanate molecule, thereby enhancing its nucleophilicity. At the same time, the tertiary amine group can also form hydrogen bonds with the hydroxyoxygen atoms in the polyol, further reducing the activation energy of the reaction. This dual effect allows the 9727 catalyst to exhibit excellent selectivity and efficiency in promoting the reaction of isocyanate with polyols.

[ R-NCO + R’-OH xrightarrow{text{hydrogen bond}} R-NH-CO-O-R’ ]

3. Stability of reaction products

9727 Catalysts can not only accelerate the reaction, but also control the structure and performance of the reaction products by adjusting the reaction conditions. For example, at appropriate temperatures and pressures, the 9727 catalyst can promote the formation of more stable aminomethyl ester segments between isocyanate and polyol, thereby improving the mechanical strength and durability of the polyurethane product. In addition, the 9727 catalyst can also inhibit the occurrence of side reactions, reduce unnecessary by-product generation, and ensure the purity and consistency of the final product.

4. Mechanisms of low odor and low VOC emissions

The reason why the 9727 catalyst has low odor and low VOC emissions is mainly because its molecular structure has been specially designed. Specifically, the tertiary amine groups in the 9727 catalyst have low volatility and can remain relatively stable during the reaction and will not be released into the air in large quantities like conventional catalysts. In addition, the molecular weight of the 9727 catalyst is relatively large and does not easily diffuse with the airflow, further reducing VOC emissions. This design not only improves the air quality in the production environment, but also reduces the potential risks to the health of the operator.

5. Effects of temperature and humidity

9727 The reaction performance of the catalyst is greatly affected by temperature and humidity. Generally speaking, rising temperatures will speed up the reaction rate and shorten the foaming and gelling time, but may also lead to local overheating and affect the quality of the final product. Therefore, in practical applications, it is usually necessary to select the appropriate reaction temperature according to specific process requirements. The impact of humidity on the 9727 catalyst is more complicated. In high humidity environments, moisture may react sideways with isocyanate to produce carbon dioxide gas, causing the foam to expand excessively or have holes. Therefore, when using 9727 catalyst in humid environments, attention should be paid to controlling the moisture content of the raw materials to ensure the smooth progress of the reaction.

Comparison of 9727 Catalysts with other types of catalysts

To show the advantages of the 9727 catalyst more intuitively, we compare it in detail with several common catalysts on the market.

Bis(2-dimethylaminoethyl) ether 0.9 1.1 20-60
TMR-2 Catalyst 0.8 0.9 20-80

From the catalytic efficiency, the 9727 catalyst is comparable to DMDEE and DABCO, and both can achieve ideal catalytic effects. However, the reaction rate of the 9727 catalyst is relatively slow and is suitable for application scenarios where a longer operation window is required. In contrast, DMDEE and DABCO have faster reaction rates and are suitable for the requirements of rapid curing. Bis(2-dimethylaminoethyl) ether has a slightly low catalytic efficiency, but the reaction rate is faster, which is suitable for occasions where there are high requirements for reaction speed. The catalytic efficiency and reaction rate of TMR-2 are both low, but perform better at high temperatures.
