The invention provides a zirconium oxide modified novel high temperature resistant ceramic car disc brake pad and a preparation method of the brake pad. The brake pad is prepared by the following steps: mixing barium sulfate, red copper fiber, ceramic fiber, zirconium oxide, synthetic graphite, antimony trisulfide, aramid fiber, mica powder, frictional powder, phenolic resin, light calcium carbonate and rubber powder, and putting the mixture into an oven with 70 DEG C to form mixed surface material; preparing steel fiber, synthetic graphite, flake graphite, petroleum coke powder, blanc fixe, porous iron powder, phenolic resin, light magnesium oxide, rubber powder and wollastonite into mixed backing material in the same way; pre-pressing and molding the mixed backing material, the mixed surface material and steel backing on a cold-pressing molding machine, then putting the product into a hot-pressing molding mould, and carrying out hot-pressing molding; after that, putting the product into a heat treatment oven, and carrying out heat treatment; and grinding the surface of the product, processing by other existing steps, and packaging. The zirconium oxide modified novel high temperature resistant ceramic car disc brake pad is free from heat fade, stable in friction coefficient, good in friction performance, stable in brake, sensitive and reliable, low in hardness and low in wear rate.
