Rubber is an elastic material made from natural or synthetic Polymers materials. It has the characteristics of softness and toughness, and can be widely used in a variety of Rubber Products such as automobile tyres, rubber hoses, rubber shoes and so on. Rubber accelerator is a 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 softness and toughness of rubber is due to the cross-linking structure of rubber molecules, and the role of rubber accelerator is to accelerate the cross-linking reaction, so that the rubber molecules in the heating and compression conditions can be faster to form the cross-linking structure, so as to improve the softness and toughness of rubber products.
Rubber accelerators play a role in the mechanism of the following aspects: 1. Reaction with vulcanising agents to form reactive species: rubber accelerators usually react with vulcanising agents to form reactive thiol species. These reactive species are able to react with the double bonds in the rubber molecule to form a cross-linked structure. Through the synergistic effect with vulcanising agents, rubber accelerators can accelerate the vulcanisation reaction of rubber and increase the cross-linking density of rubber, thus improving the strength and toughness of Rubber Products. 2. Promote the vulcanisation reaction: rubber accelerator can act as a catalyst to accelerate the vulcanisation reaction. Vulcanisation 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 vulcanisation reaction, improve the speed of vulcanisation, thereby shortening the production cycle of rubber products and improving production efficiency.
3. Improve the fluidity of rubber: rubber accelerator can improve the fluidity of rubber, so that the rubber is easier to flow and fill the mould during processing. Rubber needs to go through extruding, calendering, injection moulding and other steps in the process, and the flowability is the key factor to ensure that the rubber is evenly distributed in the process and fill the mould. 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 vulcanisation 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.
