High-temperature-resistant rubber tire and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant rubber tire which contains the following components: 20-28% of butadiene styrene rubber, 18-22% of chlorinated rubber, 5.6-6.2% of organic siliconresins, 4.5-5.5% of methyl phenyl silicone resin, 3.4-4.7% of magnesium silicate, 3.1-3.8% of calcium silicate, 2.6-3.4% of adhesive power polystyrene particles, 4.6-5.6% of modified borax, 2.4-2.9% of a high-temperature-resistant adhesive, 1.7-2.3% of high-temperature-resistant fibers, 4.85-5.46% of a vulcanizing agent, 3.62-3.85% of an accelerant and the balance of other assistants. The invention further discloses a preparation method of the high-temperature-resistant tire. The preparation method comprises the following steps: heating, stirring, vulcanizing, preparing the modified borax, preparing viscous colloid, plastifying by a tire building machine, drying and molding. The formula disclosed by the invention is reasonable, the rubber tire material has excellent adhesion property, insulating property, corrosion resistance and flame-retardant property, the properties are obviously improved, the pressure resistance and high temperature resistance are obvious, the prepared rubber tireis hard in blowout at a high temperature, the rubber tire can be used for a long time, and the safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a high temperature resistant rubber tire and a preparation method thereof. Background technique [0002] Rubber tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal rims, which can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires It is often used under complex and harsh conditions. It is subjected to various deformations, loads, forces, and high and low temperature effects when driving, so it must have high load-bearing performance, traction performance and cushioning performance; however, existing rubber tires Most of them still have the defect of poor high temperature resistance, and tires are prone to burst under high temperature conditions, which reduces the safety performance of rubber tires an...

[0002] Rubber tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal rims, which can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires It is often used under complex and harsh conditions. It is subjected to various deformations, loads, forces, and high and low temperature effects when driving, so it must have high load-bearing performance, traction performance and cushioning performance; however, existing rubber tires Most of them still have the defect of poor high temperature resistance, and tires are prone to burst under high temperature conditions, which reduces the safety performance of rubber tires and cannot meet the needs of rubber tires for high temperature and high pressure resistance; for this reason, we propose a high temperature resistant Rubber tire and its preparation method
