The invention relates to a tire sidewall rubber composition containing a sustainable material, a preparation method of the tire sidewall rubber composition and a tire, and the tire sidewall rubber composition containing the sustainable material is prepared from the following components in parts by weight: 30-70 parts of natural rubber, 0-30 parts of petroleum-based butadiene rubber, 10-40 parts of bio-based butadiene rubber and 6-40 parts of reinforcing carbon black, the rubber is prepared from the following components in parts by weight: 10-35 parts of regenerated carbon black, 1-3 parts of stearic acid, 2-5 parts of zinc oxide, 1.5-3.0 parts of a vulcanizing agent, 0.5-1.5 parts of an accelerant, 4-7 parts of an anti-aging agent, 3-5 parts of a plasticizer and 2-5 parts of a tackifier. According to the tire sidewall rubber composition containing the sustainable materials, the two sustainable materials, namely the bio-based rubber and the regenerated carbon black, are combined, so that the physical property of a rubber material can be maintained, the rolling resistance of the rubber material is improved, meanwhile, the use of fossil raw materials is reduced, and the production cost is reduced. The current situation that a large number of petroleum-based products are used in existing tire components is relieved.
本发明涉及一种包含可持续材料的轮胎胎侧橡胶组合物及其制备方法和轮胎,所述包含可持续材料的轮胎胎侧橡胶组合物由以下重量份的组分制备而成:30‑70份天然橡胶,0‑30份石油基丁二烯橡胶,10‑40份生物基丁二烯橡胶,6‑40份补强炭黑,10‑35份再生炭黑,1‑3份硬脂酸,2‑5份氧化锌,1.5‑3.0份硫化剂,0.5‑1.5份促进剂,4‑7份防老剂,3‑5份增塑剂,2‑5份增粘剂。本发明提出的包含可持续材料的轮胎胎侧橡胶组合物将生物基橡胶与再生炭黑两种可持续材料进行组合,不仅能够维持胶料物性,而且还提升了胶料的滚阻性能,同时减少了化石原料的使用,缓解了现在轮胎部件中大量使用石油基产品的现状。
