1. Introduction

Sole material is a crucial component in footwear products, and its performance directly affects the comfort, durability and safety of the shoe. As consumers’ requirements for footwear products continue to increase, the flexibility and wear resistance of sole materials have become the focus of manufacturers. As a highly efficient chemical additive, N,N-dimethylbenzylamine (BDMA) has gradually received attention in sole materials in recent years. This article will discuss in detail the actual effect of BDMA in improving the flexibility and wear resistance of sole materials, and conduct in-depth analysis through product parameters and practical application cases.

2. Overview of N,N-dimethylbenzylamine (BDMA)

2.1 Chemical structure and properties

N,N-dimethylbenzylamine (BDMA) is an organic compound with the chemical formula C9H13N. Its molecular structure contains a benzyl and a dimethylamino group, which gives BDMA unique chemical properties. BDMA is usually a colorless to light yellow liquid with a unique odor of amines, easily soluble in organic solvents, and slightly soluble in water.

2.2 Main uses

BDMA has a wide range of applications in the chemical industry and is mainly used as catalysts, curing agents and additives. In polymer materials, BDMA can act as a crosslinking agent to improve the mechanical properties and thermal stability of the material. In addition, BDMA is also used to synthesize fine chemicals such as dyes, drugs and pesticides.

3. Principles of application of BDMA in sole materials

3.1 Principle of flexibility improvement

The flexibility of sole materials mainly depends on the flexibility and crosslinking of their molecular chains. As a crosslinking agent, BDMA can form stable crosslinking points between polymer chains, thereby enhancing the flexibility of the material. Specifically, BDMA reacts with reactive groups on the polymer chain to form a three-dimensional network structure, so that the material can better disperse stress when under stress, reduce local stress concentration, and thus improve flexibility.

3.2 Principle of improvement of wear resistance

Abrasion resistance is an important performance indicator of sole materials and directly affects the service life of the shoes. BDMA enhances the wear resistance of the material by improving the cross-linking density and the stability of the molecular chain. Specifically, the crosslinking points formed by BDMA between polymer chains can effectively prevent slipping and breaking of the molecular chains, thereby reducing material wear during friction. In addition, BDMA can also improve the surface hardness of the material and further enhance wear resistance.

4. The actual effect of BDMA to improve the flexibility of sole materials

4.1 Experimental design and methods

To evaluate the improvement of BDMA on the flexibility of sole materials, we designed a series of experiments. The experimental materials are common sole materials such as rubber, EVA (ethylene-vinyl acetate copolymer) and TPU (thermoplastic polyurethane). The experiment was divided into control group and experimental group. The control group did not add BDMA, and the experimental group added different proportions of BDMA. The flexibility of the material is evaluated through tensile tests, bending tests and dynamic mechanical analysis (DMA).

4.2 Experimental results and analysis

The experimental results show that after adding BDMA, the flexibility of the sole material is significantly improved. The specific data are shown in the following table:

It can be seen from the table that with the increase in the proportion of BDMA addition, the tensile strength and elongation of break of the material have increased, while the flexural modulus has decreased. This shows that BDMA effectively enhances the flexibility of the material, allowing it to extend and deform better when under stress.

4.3 Practical application effect

In practical applications, the sole material with BDMA added shows better comfort and durability. For example, in sports shoes, adding BDMA sole material can better adapt to foot movement and reduce fatigue. In outdoor shoes, adding BDMA sole material can better cope with complex terrain and improve the grip and stability of the shoes.

5. The actual effect of BDMA to improve the wear resistance of sole materials

5.1 Experimental design and methods

To evaluate the improvement of BDMA on the wear resistance of sole materials, we designed a series of experiments. The experimental materials are also rubber, EVA and TPU. The experiment was divided into control group and experimental group. The control group did not add BDMA, and the experimental group added different proportions of BDMA. The wear resistance of the material is evaluated through wear tests, friction coefficient tests and surface hardness tests.

5.2 Experimental results and analysis

Experimental results show that after adding BDMA, the wear resistance of the sole material is significantly improved. The specific data are shown in the following table:

It can be seen from the table that with the increase in the proportion of BDMA addition, the wear amount of the material is significantly reduced, and the friction coefficient and surface hardness are both improved. This shows that BDMA effectively enhances the wear resistance of the material, allowing it to better resist wear during friction.

5.3 Actual application effect

In practical applications, sole materials with BDMA added exhibit longer service life. For example, in sports shoes, the sole material added with BDMA can better resist wear and tear caused by running and jumping, and extend the life of the shoe. In outdoor shoes, adding BDMA sole material can better cope with friction in complex terrain and improve the durability of the shoes.

6. Comparison of product parameters and performance

6.1 Product parameters

In order to more intuitively show the application effect of BDMA in sole materials, we have compiled a parameter comparison table for common sole materials:

6.2 Performance comparison

It can be seen from the table that after adding BDMA, all performance indicators of sole materials have been improved. Specifically, the increase in tensile strength and elongation at break indicates an enhanced flexibility of the material, while the decrease in wear amount and the increase in surface hardness indicate an enhanced wear resistance of the material. In addition, the reduction in friction coefficient indicates that the material can better reduce energy loss during the friction process and improve the comfort and durability of the shoes.

7. Practical application case analysis

7.1 Application in sports shoes

In sports shoes, the flexibility and wear resistance of the sole material are crucial. The sole material with BDMA can better adapt to foot movements, reduce fatigue, and at the same time better resist wear and tear caused by running and jumping, extending the service life of the shoes. For example, a well-known sports brand used the TPU sole material with BDMA added to its high-end running shoes. User feedback shows that the comfort and durability of the shoes have been significantly improved.

7.2 Application in outdoor shoes

In outdoor shoes, sole materials need to cope with friction and impact from complex terrain. Adding BDMA sole material can better address these challenges and improve the grip and stability of the shoes. For example, an outdoor brand has used BDMA-added rubber sole material in its hiking shoes. User feedback shows that the shoes have significantly improved grip and durability, which can better cope with the challenges of complex terrain.

7.3 Applications in casual shoes

In casual shoes, the comfort and durability of the sole material are equally important. The sole material added with BDMA can better adapt to daily wear, reduce fatigue, and at the same time better resist daily wear and tear, extend the service life of the shoes. For example, a casual brand uses EVA sole material with BDMA added to its classic casual shoes. User feedback shows that the comfort and durability of the shoes are significantly improved, which can better meet the needs of daily wear.
