The invention belongs to the technical field of rubber materials, and particularly relates to an airtight rubber material containing pyrolysis carbon black with wide particle size distribution, a preparation method of the airtight rubber material and a tubeless self-sealing tire. The airtight rubber material provided by the invention uses the cracked carbon black and the carbon black with wide particle size distribution, so that infiltration and mixing in raw rubber are facilitated, the dispersity is improved, the airtightness and physical and mechanical properties of the rubber material used by a tire airtight layer are improved, and meanwhile, the preparation cost is also reduced by using the cracked carbon black obtained by recycling waste tires; therefore, the technical problem that in the prior art, the physical and mechanical properties and the air tightness of a rubber material formula for a tire airtight layer need to be improved is solved.
本申请属于胶料技术领域,尤其涉及一种含宽粒径分布裂解炭黑的气密性胶料及制备方法和无内胎自密性轮胎;本申请提供的气密性胶料中使用了宽粒径分布的裂解炭黑和炭黑,有利于生胶中的浸润及混入,提高分散性,改善轮胎气密层所用的胶料的气密性和物理机械性能,同时使用废旧轮胎回收再生得到的裂解炭黑还降低了制备成本,从而解决现有技术中轮胎气密层所用的胶料配方物理机械性能和气密性有待提高的技术问题。
