Strengthened and heat-conducting rubber for heavy truck tire shoulder

Abstract

The invention provides a strengthened and heat-conducting rubber for a heavy truck tire shoulder, belonging to the technical field of rubber products. The existing pure-carbon-black-filled rubber for the tire shoulder has the problems that the heat generated under dynamic conditions is high, the heat conductivity is low and the rubber is easily destroyed at a high temperature. The strengthened and heat-conducting rubber for the heavy truck tire shoulder comprises the following components in parts by weight: 100 parts of raw rubber, 0.5-2 parts of 203 resin, 10-60 parts of carbon black, 5-100 parts of nano alumina, 0.5-10 parts of silane coupling agent, 1-3 parts of antioxidant, 1-5 parts of stearic acid, 3-5 parts of zinc oxide, 1-5 parts of accelerator, 1-10 parts of crosslinking agent, 2-15 parts of softener and 0.1-0.8 part of anti-scorching agent. The rubber composite material for the heavy truck tire shoulder has the excellent characteristics of high strength, low heat generationand high heat conductivity.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and specifically relates to a high-reinforcement, low-heat-generating, high-strength rubber compound comprising masterbatches composed of natural rubber and synthetic rubber, softeners, carbon black, nanometer metal oxides, silane coupling agents, and other components. Rubber compound for thermally conductive automotive truck tire shoulders. Background technique [0002] Due to its unique high elasticity, rubber is widely used in many fields such as industrial production and life. Rubber is a poor conductor of heat, coupled with the viscoelastic properties of rubber itself, so that the heat generated by hysteresis loss of rubber products cannot be exported in time under long-term periodic loads, resulting in a rapid rise in the internal temperature of the product. Especially for automobile tire products, when the driving speed is high, the strain frequency of each part of the material is...

AI Technical Summary

Problems solved by technology

The tire shoulder rubber works at high temperature for a long time, which accelerates its aging speed and rapidly reduces its mechanical properties, and even leads to serious problems such as degradation of rubber molecular chains and structural damage under high stress, which greatly shortens its service life.

If a large-scale structural damage occurs during operation, it is likely to cause an accident and cause heavy losses to life and property
