Frictional heat self-sintering antifriction material

Abstract

The invention belongs to the friction material field of friction stopping devices used in transport machinery and various engineering operation machineries, and relates to a friction heat self-sintering friction-resistant material. The material comprises the following raw materials by weight percent: 10 to 16 percent of adhesive, 8 to 20 percent of modified framework material, 10 to 20 percent of friction stabilizer, 10 to 25 percent of plasticizing fiber, 5 to 15 percent of various auxiliary agents, 3 to 13 percent of sintering material, 8 to 18 percent of friction-increasing agent, 2 to 8 percent of chopped glass fiber, 3 to 16 percent of petroleum coke and 4 to 16 percent of coke dust. The invention is characterized in that: ceramic-like material is converted into compound with low melting point by utilization of the heat on a friction surface; moreover, the conversion ensures that grains are refined and compact and distributed more evenly. Test result shows that the friction material has stable friction coefficient, small fluctuation, not more than +-0.035 deviation, less abrasion loss, long service life, no braking noise, no smoke and spark and no dust; moreover, the outstanding characteristic of the friction material lies in that the material does not cause damages on a brake drum (disc).
