Abstract

A ceramic brake pad of high-performing automobile comprises the following components according to weight percentages: 7%-11% of ceramic fibre, 7-9% of glued aluminium silicate fibre, 5-8% of polyacrylonitrile fibre, 2-3% of aramid fibre 7-9% of red copper fibre, 7-10% of acicular aedelforsite fibre, 7-12% of barite, 7-9% of chromite, 1-2% of butyronitrile rubber, 7-11% of graphite particle, 0.2-0.5% of zinc oxide, 5-8.5% of calcined petroleum coke, 1-3% of expansion graphite, 6-10% of boron containing phenolic resin, 3-5% of magnetite, 1-1.5% of heavy-burned magnesia, 0.3-0.5% of modified whiten bead of resin acceptor, 3-5% of boron nitride and 0.3-0.5% of alumina; the invention can form excellent friction layer and transmission film in using process, thereby having good lubricating effect without damaging the couple plate; therefore, the service life of the friction material is greatly prolonged.

Description

technical field [0001] The invention relates to a brake pad, in particular to a high-performance automotive ceramic brake pad. Background technique [0002] Semi-metal or metal-less brake pads are one of the non-asbestos friction materials that are mainly promoted and applied in my country. However, the semi-metallic brake pads are severely corroded under the action of moisture, and the noise and vibration are relatively high during braking, which will cause certain damage to the brake disc. In addition, most semi-metallic or metal-less brake pads are prone to dust generated during use. These dusts are adsorbed on the wheel hub. Because it is difficult to clean, it is easy to cause corrosion of the wheel hub due to its long-term influence. Although ceramic brake pads have the advantages of long service life, no rust, high friction coefficient, and low noise. However, at present, foreign companies regard the formula of ceramic brake pads as a commercial secret, and the form...
