Abstract

A manufacturing method of a friction plate is disclosed. The method includes a step of weighing and mixing materials, namely a step of weighing cellulosic fiber, aramid fiber pulp, phenolic resin, zinc stearate, zirconium silicate, potassium feldspar powder, calcium carbonate, biotite powder, fluorite powder, magnesium oxide, barium sulfate, antimony sulfide, micaceous iron oxide, iron oxide black, potassium hexatitanate whiskers, copper fiber, frictional powder, rubber powder, crystalline flake graphite, electrolytic copper powder and zinc powder, and mixing to obtain a material mixture, a step of subjecting a metal substrate to surface treatment, namely a step of subjecting the metal substrate to shot blasting, cleaning the metal substrate with a diluted acid solution, cleaning the metal substrate with clear water, drying the metal substrate and cooling the metal substrate, a step of cold press molding, a step of glueing, and a step of vulcanization. The manufactured friction plate is high in inner bonding strength and high in adhesive strength. Continuity of friction materials is maintained. Torque transmission capacity and mechanical strength of the friction plate are improved. The service lifetime of the friction plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a method for manufacturing a friction plate. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking and clutch plates are used for transmission. [0003] Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction. For example, the clutch plate transmits power, and the brake plate absorbs kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and even critical material. [000...
