The invention provides modified resin for a tire tread. The modified resin is characterized by being prepared from the following raw material components: 50-60 parts of nylon, 3-5 parts of tea polyphenol, 2-7 parts of absolute ethyl alcohol, 1-2 parts of sodium hydroxide and 1-3 parts of [Cu (NH3) 4] S04. And 5-10 parts of liquid rubber. The modified resin has the beneficial effects that the modified resin disclosed by the invention is used in a tire tread rubber formula, so that the tensile strength, hardness and tear strength can be ensured on the premise that the wear resistance and compression heat generation are improved, the use of natural rubber can be reduced, and the cost of tire raw materials is reduced.

    本发明提供了一种用于轮胎胎面的改性树脂,其特征在于:所述改性树脂的制备原料包括以下组分:尼龙50‑60份,茶多酚3‑5份,无水乙醇2‑7份,氢氧化钠1‑2份,[Cu(NH3)4]S041‑3份;液态橡胶5‑10份。本发明的有益效果为:在轮胎胎面胶配方中使用本专利公开的改性树脂,在耐磨性和压缩生热有所提高的前提下,能保证拉伸强度、硬度和撕裂强度,且能减少天然橡胶的使用,降低了轮胎原材料的成本。
