Abstract
This invention discloses a novel granulating process used in automobile brake-shoes production. The process comprises: uniformly mixing cashew nut oil resin, NBR latex, natural graphite, carbon fibers, wollastonite fibers and calcium carbonate, placing mixed friction material into a mesh-type granulator, granulating, then placing in an oven, baking, uniformly mixing resin, steel fibers, copper powder, friction powder, petroleum coke and NBR, mixing the two mixed materials, placing with steel back in a holotype hot press, molding by hot pressing, baking, cooling to normal temperature, grinding and spraying plastic to obtain automobile brake-shoes. The obtained automobile brake-shoes have such advantages as high heat resistance and long service life.
Description
Technical field: the present invention relates to the automobile brake sheet manufacturing process technology field, is a kind of novel granulation process that is used for the automobile brake sheet manufacturing process more specifically.
Background technology: in Motor Vehicle Braking Procedure, heat fading is too high, influences the work-ing life of brake facing.
Summary of the invention:, the objective of the invention is to design a kind of novel granulation process that is used for the automobile brake sheet manufacturing process for overcoming above-mentioned shortcoming.Its technical scheme is: get cashew nut oil resin 20 weight parts, butadiene acrylonitrile rubber breast 10 weight parts, natural graphite 20 weight parts, carbon fiber 10 weight parts, wollastonite fibre 20 weight parts, lime carbonate 20 weight parts, be mixed into the compound of 100 weight parts, put into whipping appts, stirred 5 minutes, it is mixed; Mixed friction materials is put into the particle that the mesh-type tablets press manufactures diameter 3mm, put into baking oven again and toast, temperature is 100 ℃, and the time is 2 hours; It is stand-by to make the back; Get resin 10 weight parts in addition, steel fiber 50 weight parts, copper powder 10 weight parts, friction powder 10 weight parts, petroleum coke 15 weight parts, nitrile rubber 5 weight parts are mixed into the compound of 100 weight parts, put into whipping appts, stir 5 minutes, and it is mixed; The material that mixes for twice is placed in the whipping appts, stirred 5 minutes, it is mixed; The steel backing that the material that final blending is good transfers with stamping procedure by the sheet weighing is put in and carries out hot-formingly on the holotype thermocompressor, and system pressure is 18Mpa, and back pressure pressure is 13-15Mpa; Dwell time is 260 seconds; Temperature is 160 ± 5 ℃ of patrixes, in, counterdie is 165 ± 5 ℃; The friction materials product that presses is put into baking oven to be toasted, temperature is 180 ± 2 ℃, and the time is 3 hours ± 5 minutes, after the friction materials product that baking is finished is cooled to normal temperature, carry out grinding and plastic-blasting more successively, make the automobile brake sheet that utilizes novel granulation process to make.The advantage of this invention is: improve the resistance to elevated temperatures of brake facing, fading rate is reduced to 25% by original 40%, has improved its work-ing life.
Embodiment: get 100 kilograms of particulate material that make, wherein the cashew nut oil resin is 20 kilograms, 10 kilograms of butadiene acrylonitrile rubber breasts, 20 kilograms of natural graphites, 10 kilograms on carbon fiber, 20 kilograms of wollastonite fibres, 20 kilograms in lime carbonate; Get 200 kilograms of mixed friction materialss again, its composition is 20 kilograms of resins, 100 kilograms of steel fibers, 20 kilograms of copper powders, 20 kilograms in friction powder, 20 kilograms of petroleum cokes, 10 kilograms of nitrile rubbers; 100 kilograms of particulate material that make and 200 kilograms of mixed friction materialss are mixed, and mixed friction materials is put in by the sheet weighing and carries out hot-formingly on the holotype thermocompressor, and system pressure is 18Mpa, and back pressure pressure is 14Mpa; Dwell time is 260 seconds; Temperature is 160 ℃ of patrixes, in, counterdie is 165 ℃; The friction materials product that presses is put into baking oven toast, temperature is 180 ℃, and the time is 3 hours, after the friction materials product that baking is finished is cooled to normal temperature, carries out grinding and plastic-blasting more successively, makes 2120 of automobile brake sheets that utilize novel granulation process.
