Abstract
The invention discloses an analogous ceramic high-temperature resistant friction material and a preparation method thereof, which are used for solving the technical problem of poor heat resistance of the traditional friction material. The analogous ceramic high-temperature resistant friction material is prepared by replacing a phenolic resin adhesive in an organically synthesized friction material with an inorganic liquid water-soluble aluminum silicate adhesive, and the heat resistance of the friction material is enhanced because the analogous ceramic high-temperature resistant friction material does not contain organic components. The analogous ceramic high-temperature resistant friction material is not reduced in friction coefficient after being ablated at the high temperature of 600 DEG C; and in addition, the friction material with ceramic characteristics is prepared by discarding a high-temperature sintering process of the traditional ceramic friction material on the aspect of a preparation process and adopting a preparation process of the organically synthesized friction material, thereby the cost is greatly lowered.
