Abstract

The invention discloses a brake pad with low wear rate and a preparation method thereof. In terms of parts by weight, the brake pad is composed of: 45-55 parts of high manganese steel, 18-24 parts of iron powder, 15-25 parts of carbon fiber, 8-14 parts of ethylene-vinyl acetate copolymer, 5-8 parts of lithium 8-12 parts of potassium titanate whiskers, 6-10 parts of nylon powder, 14-20 parts of nitrile rubber powder, 3-5 parts of brown corundum, 4-6 parts of grinding aid, 20-25 parts of graphite, 2 to 4 parts of chemical modifiers. Its preparation method is to weigh high manganese steel, iron powder, lithium, nylon powder, brown corundum and graphite, stir evenly, add absolute ethanol, grinding aid and chemical resistance modifier, dry after ball milling; weigh carbon Fiber, ethylene-vinyl acetate copolymer, potassium titanate whiskers and nitrile rubber powder, add water, and stir evenly; mix the two-step results evenly, hot press molding, take out the rough mold, dry it, and cut it after cooling. On the basis of maintaining excellent heat resistance, the brake pad of the invention greatly reduces the amount of wear and prolongs the service life.

Description

technical field [0001] The invention relates to a brake pad and a preparation method thereof, in particular to a low wear rate brake pad and a preparation method thereof, belonging to the technical field of brake pads. Background technique [0002] Any kind of mechanical equipment and moving vehicles must have brakes or transmissions. Friction material is a critical component on such a brake or transmission. Its main function is to absorb or transmit power through friction. If the clutch plate transmits power, the brake plate absorbs the kinetic energy. They enable machinery and various motor vehicles to work safely and reliably. Therefore, friction material is a widely used and even critical material. Performance requirements of friction materials: good friction coefficient and wear resistance, as well as certain heat resistance and mechanical strength, which can meet the performance requirements of vehicle or mechanical transmission and braking. The brake pads are squ...
