Problems solved by technology

The surface of the disc (hub) is as smooth as a mirror, and there will be no friction furrows. It is smoother, increases the friction surface, makes the friction force more stable, and has stronger braking performance. It has completely solved the problem in the production process and material formula. Noise problem, no noise at all; low cost, simple molding process

The formula comprises the following components in proportions: 7-9 parts of phenolic resin, 5 parts of butadiene-acrylonitrile rubber powder, 10-15 parts of ceramic fiber, 10-12 parts of mineral fiber, 4-6 parts of Kevlar fiber, 12-20 parts of potassium titanate whisker, 7-10 parts of synthetic graphite, 6-8 parts of zinc sulfide, 7-9 parts of red copper powder, 8-10 parts of white vermiculite and 6-10 parts of compound silicate whisker; the manufacturing method of the ceramic brake pad comprises the following steps: material preparation-material mixing-hot forming-thermal treatment-grinding-spraying; and the ceramic brake pad has the advantages of being free of noise and ash, having no corrosion on hubs, being long in service life and environment-friendly, and the like.

Description

Technical field: [0001] The invention relates to a brake pad, in particular to a formula of a ceramic brake pad and a manufacturing process thereof. Background technique: [0002] The braking function of the brake pad is to generate friction between the braking pair, forcing the pair to brake. As motor equipment and vehicle parts, brake brake parts are one of the most important safety components of motor equipment and vehicles. 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 an...
