Rubber is an elastic material made of natural or synthetic polymer materials. It is characterized by softness and toughness, and can be widely used in various Rubber Products such as automobile tires, rubber hoses, and rubber shoes. And rubber accelerator is a kind of substance added during rubber processing, which can promote the reaction and processing performance of rubber. Rubber accelerator is usually made of organic compounds, which is an active Additive that can accelerate the cross-linking reaction between rubber molecules during the processing of rubber. The flexibility and toughness of rubber is determined by the cross-linking structure between rubber molecules, and the function of rubber accelerator is to accelerate the cross-linking reaction, so that the rubber molecules can form the cross-linking structure faster under the conditions of heating and compression, thus improving the softness and toughness of rubber products. Rubber Auxiliaries play a role in the mechanism of the following aspects: 1. Reaction with vulcanizing agents to form active species: rubber accelerators usually react with vulcanizing agents to form active thiol species. These reactive species can react with the double bonds in the rubber molecule to form a cross-linked structure. Through the synergistic effect with vulcanizing agents, rubber accelerators can accelerate the vulcanization reaction of rubber and increase the cross-linking density of rubber, thus improving the strength and toughness of Rubber Products.
2. Promote the vulcanization reaction: rubber accelerator can act as a catalyst to accelerate the vulcanization reaction. Vulcanization reaction is one of the important reactions in the processing of rubber products, which can make the rubber molecules form cross-linking structure and improve the strength and toughness of rubber. Rubber accelerator can promote the vulcanization reaction, improve the speed of vulcanization, so as to shorten the production cycle of rubber products, improve production efficiency. 3. Improve the fluidity of rubber: rubber accelerator can improve the fluidity of rubber, so that the rubber in the processing process is easier to flow and fill the mold. Rubber needs to go through extrusion, calendering, injection molding and other steps in the process, and fluidity is the key factor to ensure that the rubber is evenly distributed in the process and fill the mold. By adjusting the viscosity and hardness of rubber, rubber accelerators make rubber have better fluidity and can better adapt to different processing requirements.
4. Improve the aging resistance of rubber: Rubber products will be affected by environmental factors during use and storage, and are prone to aging. Rubber accelerator has a certain degree of resistance to ultraviolet radiation, can effectively slow down the aging process of rubber, improve the service life of rubber products and weather resistance. In summary, rubber accelerator can improve the flexibility and toughness of rubber products by accelerating the cross-linking reaction of rubber, promoting the vulcanization reaction, improving the fluidity of rubber and improving the aging resistance of rubber. Rubber accelerator plays a very important role in rubber processing, can improve the quality and performance of rubber products, to meet the different needs of people for Rubber Products.
