Abstract

The invention discloses a carbon powder reinforced resin based composite friction material and a preparation method thereof. The composite material is prepared from 55% of carbon powder, 30% of cashew nut shell oil modified phenolic resin, 5% of nitrile butadiene rubber, 5% of graphite and 5% of silicon carbide powder, wherein the sum of all the components is 100%. The preparation method comprises the following steps of modifying carbon powder, graphite and silicon carbide powder by using a silane coupling agent, and then, drying; mixing carbon powder, graphite, silicon carbide powder, resin and nitrile butadiene rubber; paving; carrying out compression molding; cooling for molding to obtain the composite material with a certain specification. Meanwhile, the prepared composite friction material is favorable in frictional wear property and wide in application range.

Description

technical field [0001] The invention relates to a composite friction material prepared by using carbon powder, modified resin and filler, in particular to a carbon powder-reinforced resin-based composite friction material and a preparation method thereof, belonging to the technical field of composite material manufacturing. Background technique [0002] Friction materials are mainly used in functional parts such as transmission, deceleration, braking, and parking in many sports machinery and equipment, and are widely used in motorcycles, automobiles, trains, aircraft, industrial machinery (injection molding machines, oil drilling rigs, construction machinery , hoisting machinery, forging equipment, agricultural machinery) brake linings, clutch surfaces, brake shoes, and brake pads. [0003] The particle size of the toner powder is small, the raw material is easy to obtain, the price is low, and the production cost is saved; and the combustion product of the toner powder is i...
