Abstract

The invention discloses a formula of motorcycle tire tube rubber. The tire tube rubber comprises, by weight, 34.2 parts of natural rubber, 11.4 parts of butadiene styrene rubber, 11.4 parts of butadiene rubber, 39.9 parts of carbon black, 2.28 parts of aromatic hydrocarbon oil, 0.513 part of accelerant CZ, 1.14 parts of sulphur, 1.14 parts of antiager RE, 0.855 part of paraffin, 2.85 parts of zinc oxide, 0.684 part of dispersing agent FS-79, 0.0855 part of scorch retarder CTP, 0.969 part of antiager 4020, 1.14 parts of internal releasing agent, 1.425 parts of stearic acid and 1.71 parts of C9 petroleum resin. The formula formed according to the weight parts is adopted for the motorcycle tire tube rubber, product quality can be effectively improved, raw material and production cost is reduced, and meanwhile the produced tire tube rubber has good air tightness, heat resistance, cold resistance, elasticity, aging resistance and small permanent deformation; tearing strength and elongation at break of the tire tube rubber are remarkably improved, the use requirements on a tire tube in a high-temperature and stretching state can be met, the use performance of the tire tube is greatly improved, and the service life of the tire tube is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a motorcycle tire inner tire rubber formula. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. [0003] Tires are usually composed of three parts: outer tire, inner tube, and cushion belt. The i...
