The invention relates to the technical field of tires, and particularly provides an automobile tire low-carbon sidewall rubber material which comprises the following components in parts by weight: 45-60 parts of natural rubber, 40-55 parts of butadiene rubber, 1-5 parts of stearic acid, 1-5 parts of hydrotalcite, 1-5 parts of an MOF material, 1-5 parts of modified graphene oxide, 1-5 parts of an anti-aging agent, 1.5-5 parts of rubber protection wax, 45-65 parts of carbon black and 5-10 parts of soybean oil. 1.5 to 2.5 parts of insoluble sulfur and 0.1 to 0.5 part of scorch retarder; the modified graphene oxide is prepared by carrying out graft modification on N-cyclohexyl-2-benzothiazole sulfinamide and then reducing the modified graphene oxide with hydrazine hydrate; the preparation method comprises the following steps: carrying out three-section mixing processing on the raw materials, and controlling the internal mixing conditions of each section to finally obtain the low-carbon sidewall rubber material for the automobile tire. Zinc pollution to the environment in the tire using process can be reduced, and the strength and the mechanical property of the tire sidewall rubber material can be improved.
本发明涉及轮胎技术领域,具体提供了一种汽车轮胎低碳胎侧胶料,按重量份数计,包括:天然橡胶45‑60份,丁二烯橡胶40‑55份,硬脂酸1‑5份,水滑石1‑5份,MOF材料1‑5份,改性氧化石墨烯1‑5份,防老剂1‑5份,橡胶防护蜡1.5‑5份,炭黑45‑65份,大豆油5‑10份,不溶性硫黄1.5‑2.5份,防焦剂0.1‑0.5份;所述改性氧化石墨烯为经N‑环己基‑2‑苯并噻唑亚磺酰胺接枝改性再用水合肼还原制备得到;其制备方法为将各原料,进行三段混炼加工,并控制各段的密炼条件,最终即得汽车轮胎低碳胎侧胶料;其可降低轮胎使用过程中对环境的锌污染,并可提升轮胎胎侧胶料的强度和力学性能。
