The invention provides a tire base rubber composition, a tire base rubber and a preparation method of the tire base rubber, and relates to the technical field of tire manufacturing. The tire base rubber composition is prepared from the following components in parts by weight: 100 parts of raw rubber, 20 to 40 parts of modified carbon nanotube/carbon black aggregate, 1 to 12 parts of active agent, 0.8 to 6 parts of accelerant, 0.8 to 6 parts of vulcanizing agent, 1 to 5 parts of anti-aging agent, 0.5 to 3 parts of tackifying resin, 0.5 to 3 parts of protective wax, 0 to 15 parts of white carbon black and 0 to 0.3 part of scorch retarder. The modified carbon nano tube/carbon black aggregate is obtained by high-temperature jet flow of a modifier and a carbon nano tube/carbon black aggregate, the dispersity of the carbon nano tube/carbon black aggregate is further improved, meanwhile, the interaction between rubber and filler is enhanced through surface modification, filler agglomeration is reduced, and the service life of the filler is prolonged. The mechanical property of the tire base rubber composition is further enhanced, heat generation is reduced, and abrasion is improved.

    本发明提供了一种轮胎基部胶料组合物、轮胎基部胶料及其制备方法,涉及轮胎制造技术领域。所述轮胎基部胶料组合物按重量份数计包括以下组分:生胶100份、改性碳纳米管/炭黑聚集体20~40份、活性剂1~12份、促进剂0.8~6份、硫化剂0.8~6份、防老剂1~5份、增粘树脂0.5~3份、防护蜡0.5~3份、白炭黑0~15份、防焦剂0~0.3份。本发明所述改性碳纳米管/炭黑聚集体由改性剂和碳纳米管/炭黑聚集体经高温射流得到,进一步的提高碳纳米管/炭黑聚集体的分散性,同时表面改性增强了橡胶与填料的相互作用,降低填料团聚,进一步增强了轮胎基部胶料组合物的力学性能、降低生热和提升磨耗。
