Problems solved by technology

At present, the two sides of most of the tires that have been scrapped are almost intact, because the tire tread is severely worn, and for the sake of driving safety, they are abandoned and used, so a lot of money is spent.

Abstract

The invention relates to the technical field of tie production and particularly relates to a rubber composition for a tire tube. The rubber composition is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of butadiene rubber, 20-30 parts of natural rubber, 10-20 parts of cover tire regenerated rubber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 2-3 parts of sulfur, 3-5 parts of stearic acid and 1-2 parts of an anti-aging agent. The tire tube prepared from the rubber composition is excellent in air preserving performance, good in ageing resistance, high in carrying capacity, relatively good in machining property and low in cost.

Description

[0001] technical field [0002] The invention relates to the technical field of tire production, in particular to a tire inner tube rubber composition. Background technique [0003] Rubber, a highly elastic polymer material with reversible deformation. It can produce a large deformation under the action of a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands. Rubber extracts the condensed milk of plants such as rubber trees and rubber grasses, and processes them to make materials with elasticity, insulation, and impermeability to water and air. High elastic polymer compound. Divided into natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various mo...
