The invention belongs to the technical field of rubber, and particularly relates to a rubber composition, a preparation method thereof and a truck tire using the rubber composition. The rubber composition is prepared from the following components in parts by mass: 100 parts of diene rubber, 0.2 to 1.5 parts of hydrazide compound, 0.2 to 1.5 parts of pyrazolone compound, 0 to 30 parts of liquid rubber, 20 to 120 parts of reinforcing filler, 0 to 10 parts of silane coupling agent, 2 to 10 parts of vulcanization activator, vulcanization accelerator, vulcanizing agent, antioxidant, resin and plasticizer. The heat generation of the tire can be obviously reduced, and meanwhile, the cutting resistance and tear resistance of the tire are improved, so that the damage resistance of the truck tire is improved.
本发明属于橡胶技术领域,具体涉及一种橡胶组合物及其制备方法、使用其的载重轮胎。所述橡胶组合物(以质量计)包括二烯烃类橡胶100份、酰肼类化合物0.2‑1.5份、吡唑啉酮类化合物0.2‑1.5份、液体橡胶0‑30份、补强填料20‑120份、硅烷偶联剂0‑10份、硫化活化剂2‑10份、硫化促进剂、硫化剂、抗氧化剂、树脂和增塑剂。本发明可以明显降低轮胎的生热同时提高轮胎的耐切割和抗撕裂性能,进而提升载重轮胎的抗破坏性能。
