Problems solved by technology

[0003] The performance of the inner tube is particularly important in the use process. The main component of the bicycle inner tube on the market is rubber, but the existing bicycle inner tube rubber is not resistant to aging, and the premature aging of the inner tube not only brings economic losses to users, but also brings danger to life

Abstract

The invention belongs to the technical field of bicycle inner tube production, and discloses an anti-aging bicycle inner tube rubber composition, which is prepared from the following raw materials in parts by weight: 30 to 40 parts of combined rubber, 10 to 20 parts of reinforcing filler, 3 to 5 parts of vulcanization accelerator, 1 to 3 parts of cross-linking agent and 2 to 5 parts of rubber anti-aging agent, the combined rubber comprises natural rubber, butyl rubber and butadiene styrene rubber. According to the anti-aging bicycle inner tube rubber composition disclosed by the scheme, the combined rubber formed by combining the natural rubber, the butyl rubber and the butadiene styrene rubber is matched with the reinforcing filler, the vulcanization accelerator, the cross-linking agent and the rubber anti-aging agent for assistance, so that the anti-aging bicycle inner tube rubber composition has good properties such as aging resistance, tear resistance and air tightness; wherein the butyl rubber has excellent air tightness and water tightness, so that the air tightness of the inner tube is ensured, and the butadiene styrene rubber has the advantages of wear resistance, heat resistance, aging resistance, better vulcanization speed than natural rubber and the like, so that the comprehensive performance of the bicycle inner tube is improved when the butadiene styrene rubber is combined with the natural rubber and the butyl rubber.

Description

technical field [0001] The invention relates to the technical field of bicycle inner tube production, in particular to an aging-resistant bicycle inner tube rubber composition. Background technique [0002] The inner tube, commonly known as the inner tube, refers to a circular elastic tube with a tire valve used to maintain the inner pressure of the tire. The valve is used to inflate and maintain a certain pressure of the air in the inner tube. [0003] The performance of the inner tube is particularly important in the process of use. The main component of the bicycle inner tube on the market is rubber, and the existing bicycle inner tube rubber is not resistant to aging, and the premature aging of the inner tube not only brings economic losses to users, but also brings Danger to life. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to propose an aging-resistant bicycle inner tube rubber composition in order to solve the shortcomings in the prior...
