Abstract

The invention relates to a ceramic brake pad. The ceramic brake pad is prepared from 21 raw materials including foam iron powder, antimony sulfide, boron glass, cryolite, silicate ester, feldspar, fatty alcohol-polyoxyethylene ether sodium sulfate, brown aluminum oxide and the like in a certain portion and is manufactured through a traditional production process. The manufactured ceramic brake pad has very good heat-resistant and abrasion-resistant properties, does not easily produce a sintering phenomenon and meanwhile is quick in heat dissipation, and the safety of an automobile is improved.

Description

technical field [0001] The invention relates to a 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. Contents of the invention [0003] Aiming at the deficiencies ...
