Abstract

The invention relates to the technical field of automobile parts, in particular to a ceramic brake pad. The ceramic brake pad is prepared from following materials including, by weight, 5-15 parts of adhesive, 23.5-33.5 parts of reinforcing agent, 1-7 parts of friction increasing agent, 11.3-21.3 parts of anti-wear lubricant, 5.7-15.7 parts of elastic flexibilizer, 27.5-37.5 parts of filling agent, wherein the reinforcing agent is formed by mixing the following materials including aramid fiber, ceramic fiber, potassium titanate whisker and calcium carbonate whisker at the weight ratio of 1:8:8:2; the anti-wear lubricant is formed by mixing the following materials including molybdenum disulfide, antimony trisulfide, graphite and calcined petroleum coke at the weight ratio of 1:3.5:1.9:1.75; the adhesive is formed by mixing the following materials including nano-rubber powder and butadiene-arylonitrile modified phenolic resin at the weight ratio of 4:6.5. The unit cost of products is lowered, the effect of noise reduction is achieved, and the impact strength of products is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a ceramic brake pad. Background technique [0002] With the rapid development of my country's automobile industry, especially the brake pads of light passenger cars have put forward higher technical requirements in terms of performance, cost, life and environmental protection. [0003] The Chinese patent with application number 201210317626.6 discloses a modified phenolic resin-based electronic ceramic brake pad, which utilizes talc porcelain fibers or high-alumina magnetic fibers with excellent electrical insulation and low cost, high frequency, high temperature, and high strength.
