Accelerator DPG-80 plays an important role in the rubber industry, mainly in accelerating vulcanization speed, improving processing performance, improving physical and mechanical properties, and improving production efficiency. The following is the detailed mechanism of action and application method:

1. Vulcanization promotion effect

Accelerate vulcanization reaction

As a vulcanization accelerator, DPG-80 can significantly speed up the vulcanization reaction of rubber. Vulcanization is a key step in the rubber production process. Through the vulcanization reaction, a cross-linked structure is formed between rubber molecules, thereby giving the rubber material excellent physical and mechanical properties. DPG-80 can reduce the temperature and time required for vulcanization and improve production efficiency.

Synergistic promotion

DPG-80 is usually used in conjunction with thiazole accelerators (such as MBT, MBTS). This synergistic effect can enhance the activity of the vulcanization system, improve the overall vulcanization effect, and optimize the performance of rubber products.

2. Improve processing performance

Easy to disperse

DPG-80 is in the form of pre-dispersed masterbatch particles, which is easy to disperse evenly during the mixing process and avoids agglomeration. This allows the accelerator to be evenly distributed in the rubber matrix, increasing the uniformity and consistency of the mixture and improving the processing properties of the rubber.

Reduce dust

The pre-dispersed form reduces the generation of dust, reduces the health risks of operating workers, and improves the cleanliness of the workshop environment. This not only contributes to operational safety but also reduces environmental pollution.

3. Improve physical and mechanical properties

Enhance mechanical properties

Rubber products using DPG-80 generally have better tensile strength, hardness and wear resistance. This is because DPG-80 can increase the vulcanization cross-linking density, making the cross-linking structure between rubber molecules tighter and more stable.

Improve anti-aging properties

By improving the vulcanization system, DPG-80 can improve the anti-aging properties of rubber products and extend their service life. This is especially important for rubber products that require long-term use and weather resistance.

4. Specific application areas

Tire industry

In tire manufacturing, DPG-80 can shorten the vulcanization time, improve production efficiency, and at the same time improve the wear resistance and anti-aging properties of tires. It is especially suitable for the production of radial tires and bias tires.

Industrial rubber products

It is widely used in the production of industrial rubber products such as conveyor belts, seals, and shock absorbers. DPG-80 helps improve the mechanical properties and service life of these products to meet the stringent requirements of industrial applications.

Shoe material production

It is used in the production of rubber parts such as soles and heels to improve wear resistance and elasticity and meet the high performance requirements of shoe materials.

5. How to use

Add method

DPG-80 can be added directly to the rubber mixture during the mixing process. It is usually added in the early stages of mixing to ensure it is fully dispersed and evenly distributed.

Dosage

The specific dosage depends on the formula and process requirements, usually between 1-3 parts (relative to 100 parts of rubber). Appropriate adjustments need to be made based on actual production conditions.

Summarize

Accelerator DPG-80 plays an important role in the rubber industry by accelerating the vulcanization reaction, improving processing performance and enhancing physical and mechanical properties. Its pre-dispersed masterbatch form not only improves the convenience and safety of use, but also significantly improves the quality and performance of rubber products. Widely used in tires, industrial rubber products and shoe materials, DPG-80 will continue to play an important role in the rubber industry.
