Novel ceramic brake pad for automobiles

Abstract

A novel ceramic brake pad for automobiles is prepared from the following raw materials in parts by weight: 6 to 8 parts of dextrin solution, 4 to 6 parts of borax glass, 3 to 8 parts of cryolite, 3 to 6 parts of silicate ester, 2 to 7 parts of white feldspar, 3 to 6 parts of fatty alcohol polyoxyethylene lauryl ether sulfate sodium, 6 to 8 parts of polyester fiber, 3 to 8 parts of alkali-free glass fiber, 1 to 4 parts of lauryl sodium sulfate, 9 to 15 parts of nickel, 3 to 6 parts of copper, 2 to 8 parts of crystalline flake graphite, 8 to 14 parts of crystalline flake graphite, 2 to 6 parts of bamboo-carbon fiber, 8 to 12 parts of modified epoxy polyurethane resin, 6 to 11 parts of chloroprene rubber, 5 to 9 parts of red copper powder and 5 to 7 parts of barium sulfate. The novel ceramic brake pad for automobiles, provided by the invention, has the benefits of very good heat-resisting and wear-resisting properties, low probability of sintering and rapidity of heat dissipation and improves the security of automobiles.

Description

technical field [0001] The invention relates to a novel automobile ceramic brake pad. Background technique [0002] When braking, it is squeezed on the brake disc or drum to generate friction, so as to achieve the purpose of vehicle deceleration and braking. Due to friction, the friction block will be gradually worn. Generally speaking, the lower the cost of the brake pads, the faster the wear. Ceramic brake pads are a kind of brake pads. Many consumers mistakenly think that they are made of ceramics at first. In fact, ceramic brake pads start from the principle of metal ceramics instead of non-metallic ceramics. The high temperature generated on the surface can reach 800-900 degrees according to the measurement, and some are even higher. However, most ordinary brake pads produce sintering reactions after repeated use. Due to the sharp rise in surface temperature, the surface material will melt and even produce air cushions.
