Tire rubber compound with strong viscosity, anti-aging and low resistance

Abstract

The invention discloses a tire rubber compound with strong viscosity, anti-aging and low resistance. The tire rubber compound comprises, by weight, 50-60 parts of natural rubber, 10-15 parts of styrene butadiene rubber, 5-7 parts of N234 carbon black, 10-15 parts of white carbon black, 1-2 parts of a silane coupling agent X50S, 3-5 parts of softening plasticizer aromatic oil, 1-2 parts of zinc oxide, 2-3 parts of stearic acid, 3-5 parts of an antioxidant, 1-2 parts of tackifier 204 resin, 1-2 parts of a homogenizing agent UB4000, 1-2 parts of sulfur, 1-2 parts of a promoter TBBS, and 0.3-0.5 parts of an anti-scorching agent CTP. The tire rubber compound reduces the rolling resistance of a tire, improves the bonding performance between rubber layers, improves the blending uniformity and dispersibility of different kinds of rubbers, and has he advantages of strong viscosity, anti-aging, low resistance, effectively prolonged fatigue life.

Description

technical field [0001] The invention belongs to the field of rubber tire manufacturing, and in particular relates to a low-resistance tire compound with strong viscosity and anti-aging properties. Background technique [0002] The rubber compound is made by mixing and mixing raw materials such as carbon black, natural rubber or synthetic rubber, and additives. As the main processing object and carrier in the tire manufacturing process, the proportion of rubber in the rubber compound usually reaches about half. Chemical substances such as additives can be used to change the physical properties of rubber such as strength, plasticity, elasticity, and durability. All semi-finished rubber parts on the tire, such as tread, sidewall and apex, etc., are made of rubber in the subsequent manufacturing process. raw material processed. [0003] Green tires are the strategic direction for the development of the global tire industry. Many countries have put forward higher requirements ...

AI Technical Summary

Problems solved by technology

Currently using furnace carbon black, such as N234, N115, etc., although the wear resistance meets the requirements, but the heat generation is high, which cannot meet the requirements of low rolling resistance tires

There are many shortcomings in the production and use of the current tire compound formula: uneven dispersion of carbon black and small materials, poor adhesion with the transition layer, and easy to appear bubbles when laminating
