Highly wear-resistant wet paper-based friction material, preparation method and use thereof

Abstract

Provided are a highly wear-resistant highly wear-resistant wet paper-based friction material, a preparation method and use thereof. A natural fiber, a synthetic fiber, a friction performance modifier, and water are mixed to obtain a slurry, the slurry is subjected to dehydration forming and drying in sequence to obtain a base paper, the base paper is impregnated in a phenolic resin impregnation solution including a nanocellulose and then dried to obtain an impregnated paper, and the impregnated paper is subjected to hot-pressing vulcanization at a temperature of not greater than 230° C. to obtain the highly wear-resistant wet paper-based friction. The nanocellulose is added into the impregnation solution, such that the nanocellulose reacts chemically with the phenolic resin to generate a network composite macromolecule during the hot-pressing vulcanization.
