The invention belongs to the technical field of tire rubber materials, and particularly discloses a cord fabric second rubber layer composition, a cord fabric and a vacuum tire. The rubber material is prepared from the following components in parts by mass: 90 to 95 parts of halogenated butyl rubber, 5 to 10 parts of BIMSM elastomer, 5 to 8 parts of polyamide resin, 4 to 5 parts of unsaturated polar plasticizer, 35 to 40 parts of carbon black, 15 to 20 parts of lamellar reinforcing filler, 1 to 2 parts of borate coupling agent, 3 to 5 parts of phenolic resin, 1 to 2 parts of methylene donor, 4 to 5 parts of zinc oxide, 2 to 3 parts of stearic acid, 0.5 to 1 part of sulfur and 0.7 to 1 part of alkylphenol disulfide. And 1.5-2 parts of an accelerant. The vacuum tire which is prepared from the cord fabric prepared by the method and does not contain the inner surface rubber has excellent air tightness, the comprehensive performance of the vacuum tire is equivalent to that of a vacuum tire containing the inner surface rubber, the preparation and laminating processes of an inner liner rubber material on a tire production line can be omitted, and the production efficiency of the tire can be improved and the reject ratio of products can be reduced.
本发明属于轮胎橡胶材料技术领域,具体公开了一种帘布层第二胶料层组合物、帘布层及真空胎,其中帘布层第二胶料层组合物,其组成按质量份计包括:90‑95份卤化丁基橡胶、5‑10份BIMSM弹性体、5‑8份聚酰胺树脂、4‑5份不饱和极性增塑剂、35‑40份炭黑、15‑20份片层补强填料、1‑2份硼酸酯类偶联剂、3‑5份酚醛树脂、1‑2份亚甲基给予体、4‑5份氧化锌、2‑3份硬脂酸、0.5‑1份硫磺、0.7‑1份烷基苯酚二硫化物、1.5‑2份促进剂。由其制得的帘布层制备的不含内面胶的真空胎具有优异的气密性,综合性能与含内面胶的真空胎相当,可取消轮胎生产线上气密层胶料的制备及贴合工艺,有利于轮胎生产效率提高及产品不良率降低。
