According to the different functions and uses of carbon black, it can be roughly classified into: tire and rubber application carbon black, pigment carbon black and conductive carbon black. a.Carbon black for tire and rubber: The main use of carbon black is as a reinforcing agent of rubber, it can form a stable chemical bond with rubber molecular chain, so as to achieve the reinforcing effect. Generally, because the larger the surface area and the higher the structure of the carbon black, the more contact area with the rubber, the better the reinforcement will be. This type of carbon black is often used in tire tread to increase its wear resistance. For rubber products, the most important is the processing performance, usually the use of low specific surface area, high structure of carbon black, so that the rubber material is easy to process and has good extrusion characteristics, while maintaining a certain degree of physical reinforcement characteristics. About 70% of the world’s carbon black is used to make tires, which is the largest application of carbon black. About 20% of the carbon black is used for industrial rubber products other than tires, of which half are used for automotive components, so about 80% of the carbon black is consumed in the automotive industry, it can be seen that the carbon black industry is closely related to the tire industry and the automotive industry.
