What material is the rubber used in the tires?
The main material of automobile tire is the most widely used rubber, natural rubber, polybutadiene rubber, styrene butadiene rubber, rubber and other Ding Ji. Early automobile tires are outside the tire structure, wherein the inner tube is made of rubber, rubber and tire cord fabric made by multilayer. Nowadays tubeless tires are mostly radial tyres. Radial tire early steel strengthened, with the development of chemical technology, replaced by synthetic fiber steel radial gradually by Kevlar and other lighter weight, higher strength.
Natural rubber (NR) is a kind of natural polymer with CIS -1, 4- polyisoprene as the main component, the molecular formula is n (C5H8), the composition of 91% ~ 94% is rubber hydrocarbon (CIS -1, 4- polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substances. Natural rubber is the most widely used universal rubber.Polybutadiene rubber is cis polybutadiene rubber -1,4-, its molecular formula is n (C4H6). Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS content of more than 95%. According to the different catalysts can be divided into nickel, cobalt, titanium and rare earth polybutadiene rubber (nd). Polybutadiene rubber is the second largest after the synthetic rubber sbr. Compared with natural rubber and styrene butadiene rubber, it is especially excellent in cold resistance, wear resistance and elasticity after vulcanization. It has less heat under the dynamic load and has good aging resistance. It is easy to use with natural rubber, chloroprene rubber or nitrile rubber. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, also can produce cushioning materials and various rubber, adhesive tape, adhesive tape and sponge etc.
The tyre is known, usually made of rubber materials, a solid tire and pneumatic tire parts, pneumatic tyre and tubeless tire composed by.
