Abstract

A method for preparing an aerogel comprising nano attapulgite and phenolic aldehyde and a method for preparing abrasion-resistant vehicle tire. 80-100 weight distributions of rubber, 3-8 weight distributions of SiO2.nH2O, 3-6 weight distributions of an anti-aging agent, 3-4 weight distributions of a heat stabilizer, 3-5 weight distributions of a compatibilizing agent, and 3-12 weight distributions of the aerogel comprising the nano attapulgite and the phenolic aldehyde is selected as a raw material of the abrasion-resistant rubber material to prepare rubber composite material for the abrasion-resistant vehicle tire.
