Abstract
本实用新型公开了一种聚氨酯橡胶组合式轮胎胎面，该胎面包括橡胶体，胎面上设有花纹沟，橡胶体上面设有凹槽，聚氨酯弹性体位于凹槽内。胎面冠部磨耗面一部分面积是聚氨酯材料，另一部分为橡胶材料。两部分材料通过共交联结合成为一体。聚氨酯部分提高了轮胎胎面的耐磨性，橡胶部分保证了胎面的防滑性和制动性，综合性能优于单一的橡胶材料胎面和聚氨酯材料胎面。可通过复合挤出或浇注方式再与橡胶胎体共硫化等工艺制成轮胎，与传统橡胶轮胎生产工艺基本相同。在目前的轮胎企业、翻新轮胎企业应用时，投资省，见效快。可用于汽车、拖拉机、三轮车等轮胎的生产。既可用于低速轮胎，也可用于高速轮胎，还可用于翻新轮胎，适用广泛。
The utility model discloses a polyurethane rubber combined tire tread. The tread comprises a rubber body, pattern grooves are arranged on the tread, grooves are arranged on the rubber body, and polyurethane elastic bodies are located in the grooves. A part of the wear surface of the tread crown is made of polyurethane material, and the other part is made of rubber material. The two-part material is bonded into one by co-crosslinking. The polyurethane part improves the wear resistance of the tire tread, and the rubber part ensures the skid resistance and braking performance of the tread, and the comprehensive performance is better than a single rubber material tread and a polyurethane material tread. It can be made into tires by composite extrusion or casting and co-vulcanization with rubber carcass, which is basically the same as the traditional rubber tire production process. When applied in current tire companies and retreaded tire companies, the investment is low and the effect is quick. It can be used in the production of tires for automobiles, tractors, tricycles, etc. It can be used for low-speed tires, high-speed tires, and retreaded tires, and is widely applicable.
Description
技术领域technical field
本实用新型涉及一种轮胎的胎面。The utility model relates to a tire tread.
背景技术Background technique
公知的轮胎胎面为橡胶材料，橡胶胎面的耐磨性差，使用寿命短。中国专利01114798和200310111979公开的轮胎胎面为全聚氨酯弹性材料，聚氨酯胎面虽然耐磨性比橡胶胎面好，但制动性和抗滑性比橡胶胎面差，行驶安全性差，目前主要用于低速轮胎。Known tire tread is rubber material, and the abrasion resistance of rubber tread is poor, and service life is short. The tire tread disclosed in Chinese patent 01114798 and 200310111979 is a full polyurethane elastic material. Although the wear resistance of the polyurethane tread is better than that of the rubber tread, the braking and skid resistance are worse than that of the rubber tread, and the driving safety is poor. for low-speed tires.
发明内容Contents of the invention
本实用新型的目的是要提供一种聚氨酯橡胶组合式轮胎胎面，该胎面不但耐磨性好，而且制动性和抗滑性也好。The purpose of the utility model is to provide a polyurethane rubber combined tire tread, which not only has good wear resistance, but also has good braking and skid resistance.
本实用新型的目的是这样实现的：该胎面包括橡胶体，胎面上设有花纹沟，橡胶体上面设有凹槽，聚氨酯弹性体位于凹槽内。The purpose of the utility model is achieved as follows: the tread includes a rubber body, the tread is provided with pattern grooves, the rubber body is provided with grooves, and the polyurethane elastic body is located in the grooves.
聚氨酯弹性体面积占胎面冠部磨耗面面积的10-60％，聚氨酯弹性体厚度大于花纹沟的深度。The area of the polyurethane elastic body accounts for 10-60% of the area of the wearing surface of the tread crown, and the thickness of the polyurethane elastic body is greater than the depth of the pattern groove.
本实用新型由橡胶体和聚氨酯弹性体按面积组合而成，即胎面冠部磨耗面一部分面积是聚氨酯材料，另一部分为橡胶材料。两部分材料通过共交联(共硫化)结合成为一体。聚氨酯部分提高了轮胎胎面的耐磨性，橡胶部分保证了胎面的防滑性和制动性，综合性能优于单一的橡胶材料胎面和聚氨酯材料胎面。可通过复合挤出或浇注(注射)方式再与橡胶胎体共硫化等工艺制成轮胎，与传统橡胶轮胎生产工艺基本相同。在目前的轮胎企业、翻新轮胎企业应用时，投资省，见效快。可用于汽车、拖拉机、三轮车等轮胎的生产。既可用于低速轮胎，也可用于高速轮胎，还可用于翻新轮胎，适用广泛。The utility model is composed of a rubber body and a polyurethane elastic body according to the area, that is, a part of the wear surface of the tread cap is made of polyurethane material, and the other part is made of rubber material. The two-part materials are combined into one by co-crosslinking (co-vulcanization). The polyurethane part improves the wear resistance of the tire tread, and the rubber part ensures the skid resistance and braking performance of the tread, and the comprehensive performance is better than a single rubber material tread and a polyurethane material tread. The tire can be made by co-extrusion or casting (injection) and co-vulcanization with rubber carcass, which is basically the same as the traditional rubber tire production process. When applied in current tire companies and retreaded tire companies, the investment is low and the effect is quick. It can be used in the production of tires for automobiles, tractors, tricycles, etc. It can be used for low-speed tires, high-speed tires, and retreaded tires, and is widely applicable.
