The invention relates to the technical field of tire rubber manufacturing, and discloses a high-grip winter tire tread rubber composition containing modified aluminum hydroxide, the modified aluminum hydroxide is added into the composition, the modified aluminum hydroxide is prepared from a silane coupling agent modified aluminum hydroxide, and the use amount of the silane coupling agent is 1-3% of the mass of the aluminum hydroxide; the BET specific surface area of the aluminum hydroxide is 10-20 m < 2 >/g, and the particle size is 1-10 microns. By adding the modified aluminum hydroxide, under the condition that the dispersity of the filler and the processability of the rubber material are not obviously influenced, the wear resistance of the tire is improved, and meanwhile, the road holding force of the tire on the ice surface is basically not influenced; the invention also provides two preparation methods of the modified aluminum hydroxide.
本发明涉及轮胎橡胶制造技术领域,公开了一种含改性氢氧化铝的高抓地冬季胎胎面胶组合物,该组合物中添加了改性氢氧化铝,改性氢氧化铝由硅烷偶联剂改性氢氧化铝制备得到,硅烷偶联剂使用量为氢氧化铝质量的1‑3%;氢氧化铝的BET比表面积为10‑20m2/g,粒径为1‑10um。本发明中改性氢氧化铝的添加能够在不明显影响填料的分散性和胶料的加工性能的情况下,提高轮胎的耐磨耗性能的同时基本不影响其冰面抓地力;且提供了两种改性氢氧化铝的制备方法。
