Polyurethane rubber composite special tire and preparation method thereof

Abstract

The invention discloses a polyurethane rubber composite special tire and a preparation method thereof. The tire includes polyurethane patterns, rubber patterns, a tire body, a wheel rim, screw holes,a bearing, spokes, a crown protection layer, an insulating layer and an airtight layer. The beneficial effects of the tire and preparation method are as follows: the surface of the provided tire bodyis formed by polyurethane and rubber which are interlaced and uniformly arranged on the surface of the tire body, so that the tire can have performance of the polyurethane material such as high-strength wear resistant performance, oil resistant performance and high temperature resistance, and have characteristics of high hardness and high strength, and the tire can also reserve the advantages of the rubber material of strong elastic properties, acid and alkali resistance and strong buffering capabilities; that drawing on the strong points of others to make up for one's own weak points can be realized by combining the two materials; and the tire is added with the crown protection layer, the insulating layer and the airtight layer from the external layer to the internal layer, so that the tire can have advantages of deep corrosion resistant performance, good thermal insulation effects and strong airtight performance.

Description

technical field [0001] The invention relates to a tire and a preparation method thereof, in particular to a polyurethane rubber composite special tire and a preparation method thereof, belonging to the technical field of automotive equipment applications. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. [0003] However, many tires currently used in automotive equipment still have some shortcomings. For example, many traditional tires have a ...

Problems solved by technology

[0003] However, many tires currently used in automotive equipment still have some shortcomings. For example, many traditional tires have a single function and are mostly rubber tires. This kind of rubber tire is easy to age in the air, has poor corrosion resistance, and is not heat-resistant. Oil resistance, poor wear resistance, low service life, hardness and strength not up to the specified requirements, thermal insulation and air tightness are not rational, many tires are easy to damage, inconvenient to repair, and the price is too high
