All-weather all-season tire and preparation method thereof

Abstract

The invention discloses an all-weather all-season tire and a preparation method thereof. The all-weather all-season tire comprises a carcass of a snow tire; the carcass comprises a grounding part anda sidewall part; the grounding part comprises an airtight layer, a base rubber layer and a polymer memory sealing layer; the polymer memory sealing layer is integrally bonded with the airtight layer through the base rubber layer; main components of the polymer memory sealing layer comprise SEBS, rubber filling oil, polyisobutene, tackifying resin, carbon black and calcium carbonate; the mass percentage content of the SEBS is 15-35%; the mass percentage content of the rubber filling oil is 8-25%; the mass percentage content of the polyisobutene is 4-12%; the mass percentage content of the tackifying resin 10-24%; the mass percentage content of the carbon black 3-8%; and the mass percentage content of the calcium carbonate is 8-20%. Through the mode, the noises can be reduced, the wear resistance is enhanced, and the remodeled snow tire can also be used in summers.

Description

Technical field [0001] The invention relates to the technical field of tires, in particular to a preparation method of all-weather four-season tires and all-weather four-season tires. Background technique [0002] In northern China, tires must be changed during the winter and summer seasons. Northern Motors needs to use special tires for winter and snow when driving on icy and snowy roads in winter. In summer, summer tires are required to achieve the best performance on dry and high-temperature roads in summer. On snow-covered roads, the traction of the tires will decrease in summer, making it easy to slip. Winter snow tires use a special soft rubber formula and pattern design, which can provide better grip, traction, better braking and handling performance on winter ice and snow wet roads, ensuring driving safety in ice and snow, but snow tires When used in a high temperature environment in summer, the noise is large and the wear resistance is poor.

AI Technical Summary

Problems solved by technology

Winter snow tires adopt special soft rubber formula and pattern design, which can provide better grip, traction, better braking and handling performance on winter ice and snow wet roads, and ensure driving safety under ice and snow, but snow tires When used in high temperature environment in summer, the noise is loud and the wear resistance is poor

[0003] Ordinary four-season tires that are common in the market can be roughly divided into two categories: the first category is four-season tires with removable rubber rings, that is, when the seasons change, there is no need to replace the tires, but the rubber rings that match the tires need to be inserted or removed. , the car owner must insert or remove the rubber ring by himself; the second type is the four-season tire with special pattern design, that is, the tire tread structure is adjusted through the design so that the tire can be used in both winter and summer. Medium tires are noisy. During winter use, their grip performance and handling are not as good as snow tires. Facing ice and snow roads, they are easy to slip and cannot guarantee driving safety.
