Problems solved by technology

[0003] Chinese patents CN201010583530.5, CN201310416105.0 and CN201010584067.6 have all improved the rubber formula, but still have not solved the problem of glue shortage
[0004] Existing technology produces tire sidewall rubber, which is rough and uneven with broken waves on the surface of the sidewall, poor viscosity, poor fluidity of the rubber material, and lack of rubber on the sidewall of the finished tire after vulcanization, which increases labor intensity and reduces production efficiency. product quality

Abstract

The invention provides automobile tire sidewall rubber for preventing starved joint. According to the specific technical scheme, the dispersion of the filler in rubber is well promoted by adding a processing aid C5, the rubber plasticity is improved, the rubber liquidity is improved, the rubber extruded surface is smooth in surface and high in adhesion, the tire sidewall starved joint of a vulcanization product is improved, and the first-pass yield of the finished product is obviously improved, so that the production cost is reduced, and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to an automobile tire side rubber for preventing rubber shortage. Background technique [0002] With the development of expressways in my country, the cost-effective advantages of radial tires are becoming more and more obvious, and the radialization rate of tires is getting higher and higher and gradually approaching the level of developed countries. Due to my country's accession to WTO, the integration of global commerce and economy, global economic slowdown and high raw material prices have increasingly affected the development of the tire industry. Product quality and price are the key to competition, so the appearance quality of tires is becoming more and more important. In particular, the requirements for the appearance of car radial tires are getting higher and higher. How to tap the potential and increase efficiency on the basis of existing production...
