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. Safety

Abstract

The invention relates to the field of brake pad, and particularly relates to an automobile ceramic brake pad and a manufacturing technology thereof. The automobile ceramic brake pad is made from the following raw materials in parts by weight: 6-10 parts of phenolic resin, 12-18 parts of ceramic fiber, 8-12 parts of mineral fiber, 4-8 parts of zinc sulfide, 6-10 parts of nitrile-butadiene rubber phenol, 7-12 parts of artificial graphite, 4-6 parts of potassium titanate fiber, 6-12 parts of steel cotton fiber, 5-8 parts of red copper powder and 6-9 parts of barite. The invention provides an automobile ceramic brake pad and a manufacturing technology thereof, wherein the automobile ceramic brake pad is reasonable in component proportioning, simple in preparation technology and good in high-temperature stability, and has stable friction coefficient, long service life and high safety.

Description

technical field [0001] The invention relates to the field of brake pads, in particular to an automotive ceramic brake pad and a manufacturing process thereof. 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 frictio...
