Problems solved by technology

As heavy-duty vehicles have a large inertia when they are fully loaded, obvious thermal recession often occurs during high-speed continuous braking, and the braking performance is unstable, resulting in smoke from the brake pads, fire and brake failure, which seriously threatens the safety of pedestrians and drivers.

Abstract

The invention discloses an automobile ceramic brake pad. The automobile ceramic brake pad comprises, by weight, 8-9 parts of phenolic resin, 14-17 parts of ceramic fibers, 9-12 parts of mineral fibers, 5-7 parts of zinc sulfide, 6-8 parts of butadiene-acrylonitrile rubber phenol, 7-9 parts of artificial graphite, 4-5 parts of potassium titanate fibers, 6-11 parts of steel wool fibers, 5-9 parts of red copper powder, 7-9 parts of barite, 0.1-1 part of brown fused alumina, 0.1-1 part of silicon carbide and 10-15 parts of calcium carbonate. To solve the technical problems, the invention provides the automobile ceramic brake pad which is reasonable in component ratio, simple in preparation process, good in high-temperature stability, stable in friction coefficient, long in service life and high in safety and a manufacturing process of the automobile ceramic brake pad.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, in particular to a ceramic automobile brake pad. Background technique [0002] Automobile brake pads are the key components of Class A of the automobile braking system, and their performance is directly related to the safety and reliability of automobile operation. As a brake material for brake pads, it is actually a composite material, which is formed by polymerization of various minerals and mineral fibers. Different models and regions have different requirements for brake material products. Friction coefficient is the most basic parameter of brake materials, which determines the braking performance of brake pads. The country strictly requires manufacturers to indicate the friction coefficient of brake pads on the product packaging. If the coefficient of friction is too high, there will be a great impact and vibration during braking. If the coefficient of friction is too low, the braki...
