Problems solved by technology

[0002] With the improvement of the quality of road conditions, car tires and truck tires are generally designed as longitudinal patterns in order to increase the driving speed, but the anti-skid effect is not good. When there is snow or ice on the road, the wheels will slip.
At present, the tire anti-skid belts commonly used in the market are mostly made of metal and plastic materials. Metal anti-skid belts are easy to damage the tires, and the bumps are severe; plastic anti-skid belts are brittle and hard at low temperatures in winter, and are easy to break; in addition, most of the commonly used anti-skid belts are chain anti-skid belts. , the contact area of ​​the anti-slip belt is small, and the anti-slip effect is poor

Abstract

The invention discloses a preparation method of a sheet-shaped rubber antiskid belt for a tire, raw rubber is prepared by combining common raw rubber, methyl phenyl vinyl silicone rubber and brominated isobutylene-p-methylstyrene rubber, so that not only can the mechanical property, the tearing property and the aging property of the rubber antiskid belt be met, but also the glass transition temperature and the brittle temperature of the rubber material can be reduced; and the use temperature of the rubber material can reach-120 DEG C, and the gripping force is also greatly improved. A vulcanization system selects an effective vulcanization system and a peroxide vulcanization system, so that the content of intramolecular combined sulfur is low, the glass-transition temperature of the rubber material is low, and the cold resistance of the rubber material is improved. In a filling system, gas-phase white carbon black is selected to replace part of carbon black, so that the ice surface gripping power and the tearing property of the rubber material can be remarkably improved. An anti-aging system is selected from a pollution-free novel anti-aging agent. And low-molecular-weight high-vinyl 1, 2-polybutadiene resin (liquid) is used as a peroxide assistant cross-linking agent, so that the low-temperature performance of the rubber material is better.
