Using reclaimed rubber instead of raw rubber to produce rubber products can greatly reduce the cost of raw materials, and the combination of reclaimed rubber and raw rubber has become the mainstream production method of rubber products, and many rubber products can even use reclaimed rubber completely, reducing raw material costs. In the production of rubber products, dispersant is a commonly used functional additive, which mainly plays the role of improving the dispersion of carbon black and other compounding agents in the rubber compound, and carbon black reinforcement is required in the production of reclaimed rubber products to further improve the product. Mechanical strength.

1. The role of dispersants in reclaimed rubber products.

HYL31Y10Y1J-SXC is a functional processing aid, its main function is to improve the dispersibility of rubber compounds and other types of rubber compounds. In the production of reclaimed rubber products, the dispersant can play an internal smoothing role when the rubber is mixed, weakening the internal friction between the rubber macromolecular chains to a certain extent, reducing the concentration of hy reclaimed rubber mixed rubber, and promoting carbon black and Dispersion of other compounding agents to improve compound processability and uniformity. Dispersants can accelerate the dispersion of fillers in the rubber mixing process, further reducing mixing time and energy consumption.

2. Amount of dispersant in reclaimed rubber products

The price of the recycled rubber compound is lower than that of the original rubber compound, but the mechanical strength is different from the original rubber compound, so carbon black reinforcement is often required; the larger the amount of carbon black, the more difficult it is to mix with other compounding agents, resulting in The reclaimed rubber cannot be uniformly mixed, so usually in the production of reclaimed rubber products with a large amount of carbon black, the amount of dispersant should be appropriately increased.

3. Compounding agents are usually used in the production of reclaimed rubber products.

High-quality rubber dispersant has excellent lubricating function, and can mix various rubber materials evenly to improve the comprehensive performance of rubber products. When producing reclaimed rubber products, it is often required to be used together with original rubber. The performance of reclaimed rubber products is of great significance, mainly including the condensation products of fatty acids, metal fatty acids, fatty acid esters, metal soap fatty acid fatty acid esters and their mixtures with metal soaps.

When using reclaimed rubber to produce rubber products, rational use of dispersants can not only promote the uniform dispersion between carbon black and compounding agents, but also improve the compatibility of rubber and rubber, reduce the probability of blooming, and make rubber It improves the plasticity and fluidity of the reclaimed rubber, improves the mixing quality of the reclaimed rubber, and greatly reduces the foaming rate; at the same time, the rubber dispersant can also improve the sulfur reduction resistance and scorch safety of the reclaimed rubber. It can be seen that in the production of reclaimed rubber products, dispersants are indeed very important.

High-quality reclaimed rubber products require the use of multiple sets of compounding agents. We will continue to work with you on other compounding agents used in reclaimed rubber products, as well as the use skills in various reclaimed rubber products.
