The invention relates to the technical field of tire preparation, and discloses syndiotactic 1, 2-polybutadiene rubber apex for tires, which is prepared from the following raw materials in parts by weight: 100 parts of rubber composition, 5 to 30 parts of reinforcing resin, 2 to 8 parts of stearic acid, 5 to 10 parts of active agent, 1 to 10 parts of anti-aging agent, 1 to 5 parts of accelerant, 0.1 to 1 part of scorch retarder, 2 to 10 parts of vulcanizing agent and 30 to 80 parts of carbon black. The prepared apex has excellent stiffness, the defect that long and thin apex is prone to deformation is overcome, the production efficiency is improved, meanwhile, it is guaranteed that the hardness of the vulcanized apex is the same as that of common apex, and the apex can be used for preparing apex with various hardness.

    本发明涉及轮胎制备技术领域,公开了一种轮胎用间同1,2-聚丁二烯橡胶三角胶,包括以下重量份原料:橡胶组合物100份,补强树脂5-30份,硬脂酸2-8份,活性剂5-10份,防老剂1-10份,促进剂1-5份,防焦剂0.1-1份,硫化剂2-10份,炭黑30-80份;本发明制备的三角胶具备优异的挺性,改善了又长又薄的三角胶易发生变形的缺点,提高了生产效率,同时保证了硫化后三角胶的硬度与普通三角胶相同,本发明可用于制备各类硬度的三角胶。
