Tire tube rubber

Abstract

The invention discloses a tire tube rubber which is prepared from the following raw materials in percentage by weight: 10-30 percent of natural rubber, 30-70 percent of reclaimed rubber, 3-5 percent of a rubber accelerator, 5-8 percent of metallic oxide, 3-6 percent of stearic acid, 1-3 percent of 4010NA1, 1-2 percent of PM1, 0.5-2 percent of tall oil, 1-3 percent of rosin, 1-3 percent of a rubber smell-covering agent and the balance of reinforcing filler. According to the tire tube rubber, damage of carbon black to the respiratory system of an operator is effectively avoided, the risk of suffering from occupational diseases by production personnel is reduced, the odor of rubber is reduced, the ageing resistance, compression resistance and impact resistance of the rubber are greatly improved, the environmental pollution is avoided, the service life of the tire rube is prolonged, and the service safety of the tire tube is improved.

Description

technical field [0001] The invention relates to tire inner tube rubber, which belongs to the technical field of rubber production. Background technique [0002] At present, in the production of vehicle inner tubes, reclaimed rubber is mainly used, supplemented by natural rubber, and carbon black is used as a reinforcement material. Although this type of rubber can meet the general needs of vehicle inner tubes, carbon black is extremely polluting. , and cause damage to the respiratory system of the operator, and the aging resistance of the inner tube produced by this type of rubber is relatively low, and the compression resistance and impact resistance are obviously insufficient, so the service life of the tire inner tube is greatly reduced, and it is easy to cause When the tire load is too large, the inner tube bursts, which poses a serious threat to driving safety. At the same time, this type of rubber also has a large odor, which also causes large pollution to the surround...

[0002] At present, in the production of vehicle inner tubes, reclaimed rubber is mainly used, supplemented by natural rubber, and carbon black is used as a reinforcement material. Although this type of rubber can meet the general needs of vehicle inner tubes, carbon black is extremely polluting. , and cause damage to the respiratory system of the operator, and the aging resistance of the inner tube produced by this type of rubber is relatively low, and the compression resistance and impact resistance are obviously insufficient, so the service life of the tire inner tube is greatly reduced, and it is easy to cause When the tire load is too large, the inner tube bursts, which poses a serious threat to driving safety. At the same time, this type of rubber also has a large odor, which also causes large pollution to the surrounding production environment and use environment.
