The invention discloses composite supporting rubber and a self-supporting tire, and belongs to the field of anti-explosion tires. The composite supporting rubber is arranged between a lining layer and a tire body layer and comprises transition supporting rubber and main body supporting rubber, the transition supporting rubber is located between the lining layer and the main body supporting rubber, the compression and tension elastic modulus of the rubber material is similar to that of the lining layer, and the transition supporting rubber is rectangular; the main body supporting rubber is located between the transition supporting rubber and the tire body layer, and the compression and tensile elasticity modulus of the rubber material is close to that of the tire body layer. The rubber composition is applied to the self-supporting tire, solves the technical problems that the existing self-supporting tire cannot meet the performance requirements of each part of the tire due to the single rubber as the supporting rubber, so that the delamination phenomenon of the tire under aging driving, low-pressure driving and zero-pressure driving occurs, the tire comfort is poor and the tire burst occurs, and has the advantages of high comfort, low cost and the like. The durability is good, the weight of the tire can be reduced, and the rolling resistance of the tire is reduced.
本发明公开了一种复合支撑胶及自体支撑轮胎,属于防爆轮胎领域。该复合支撑胶设于内衬层与胎体层之间,包括过渡支撑胶与主体支撑胶;过渡支撑胶位于内衬层与主体支撑胶之间,胶料的压缩拉伸弹性模量与内衬层的压缩拉伸弹性模量相近,形状为长方形;主体支撑胶位于过渡支撑胶与胎体层之间,胶料的压缩拉伸弹性模量与胎体层的压缩拉伸弹性模量相近。本发明应用于自体支撑轮胎方面,解决现有自体支撑轮胎因单种胶作为支撑胶无法满足轮胎各个部位的性能要求,导致轮胎出现老化行驶、低气压行驶、零气压行驶下的脱层现象,及轮胎舒适性差和轮胎爆胎的技术问题,具有舒适性高,耐久性好,可以降低轮胎重量,降低轮胎的滚动阻力的特点。
