Abstract
The gasket contains the following components: phenolic resin, urea resin, oleic acid, molybdenum disulfide, zinc oxide, barium sulfate, talcum powder, graphite powder, glass fibre, and others. It is produced by mixing to obtain base material in the condition of stirring, base material drying, hot pressing of base material and steel backboard inside die in hydraulic press, drying and post-treatment. The prodn process has no dust pollution and the product has high wear resistance and no damage to duals.
Description
The present invention relates to the disc type friction plate that the Light-duty Vehicle of a kind of braking control system of motor vehicle, particularly car is used.
More original friction plate is to adopt asbestos as reinforcing material, and people work out some asbestos-free friction plates again because of therefore it pollute to environment.As on October 5th, 1994 Gazette of Patent for Invention disclosed a kind of＜friction plate (application number 93115918.0) its to the effect that replace asbestos fiber to make the reinforcing material of friction plate with brucite fiber, specifically composed as follows: brucite 10～50%, Steel Fibre 5～15%, rubber powder 3～10%, chromite powder 3～20%, wollastonite 3～20%, vermiculite power 3～20%, graphite 3～15%, resin 15～30%.Its deficiency is product rigidity easy damaged break when braking too by force, and the raw material of product be that pulvis dust in course of working is understood production environment and be polluted the health that influences the operator substantially simultaneously.
The object of the present invention is to provide a kind of gasket for disc brake that does not damage break when no dust pollution uses in course of working again.
Purpose of the present invention can realize by following measure: a kind of gasket for disc brake that is used for car and Lightweight Vehicles, it is characterized in that: the weight percentage of each component is: phenolic resin 5～15%, urea formaldehyde resin 5～15%, oleic acid 0.5～1.5%, molybdenum disulfide 0.5～1.5%, zine oxide 4～6%, sodium fluoride 4～6%, plumbago 4～6%, tyre talc 1%, barium sulphate 12～18%, French chalk 12～18%, Iron Ore Powder 18～22%, copper fiber 4～6%, Steel Fibre 4～6%, glass fibre 1～3%.The weight percentage of each component is: phenolic resin 10%, urea formaldehyde resin 10%, oleic acid 1%, molybdenum disulfide 1%, zine oxide 5%, sodium fluoride 5%, plumbago 5%, tyre talc 1%, barium sulphate 15%, French chalk 15%, Iron Ore Powder 20%, copper fiber 5%, Steel Fibre 5% glass fibre 2%.A kind of preparation method who is used for the disk type braker of car and Lightweight Vehicles, it is characterized in that: 1. batch mixing: will phenolic resin and urea formaldehyde resin add in the stirrer and stirred 5～10 minutes, again with oleic acid, molybdenum disulfide, zine oxide, sodium fluoride, barium sulphate, French chalk, plumbago, tyre talc, Iron Ore Powder adds stirring 15～20 minutes successively, again with glass fibre, Steel Fibre and copper fiber add successively, be stirred to material and be loose condition (of surface), 2. give processing: with above-mentioned base-material drying, its fugitive constituent is controlled at 2～3%, and with the fragmentation of aniseed piece, 3. hot-forming: the mould that base-material is placed hydraulic press, put into the steel backing that scribbles Bond simultaneously, at 160～170 ℃, unit pressure 18～20MPa suppresses 1～1.5 minute/mm, will obtain the disc type blank and place baking oven to keep 6 hours in 130～160 ℃.
Raw material of the present invention mainly includes four parts such as Bond, filler, fiber and modifier.Wherein Bond is resin such as phenolic resin and urea formaldehyde resin.They respectively account for 5～15% in prescription, preferably respectively account for 10%.The filler that strengthens usefulness includes zine oxide, sodium fluoride, plumbago, barium sulphate, French chalk, Iron Ore Powder and tyre talc.Wherein zine oxide, sodium fluoride, plumbago respectively account for 4～6% in prescription, preferably respectively account for 5%.Barium sulphate and French chalk respectively account for 12～18%, preferably respectively account for 15%.Iron Ore Powder accounts for 18～22% in prescription, preferably account for 20%, and tyre talc accounts for 10% in prescription.The fiber that adds includes copper fiber, Steel Fibre and glass fibre.Wherein copper fiber and Steel Fibre respectively account for 4～6% in prescription, preferably account for 5%.Glass fibre accounts for 1～3% in prescription, preferably account for 2%.For the performance of improving friction plate also is added with modifier such as oleic acid and molybdenum disulfide in prescription.They respectively account for 0.5～1.5% in prescription, and preferably 1%.
The preparation method of product of the present invention is as follows: 1,1. hybrid adhesive of batch mixing: will phenolic resin and urea formaldehyde resin add in the stirrer and stirred 5～10 minutes.2. filler is mixed with Bond: with oleic acid, molybdenum disulfide, zine oxide, sodium fluoride, dredge sour barium, French chalk, plumbago, tyre talc, Iron Ore Powder adds to stir in the stirrer successively made it even mixing in 15～20 minutes.3. fiber is mixed with filler and Bond: under stirring condition, add glass fibre, Steel Fibre and copper fiber successively.Continue to stir again after all adding, treat that material is the base-material that is that loose condition (of surface) can discharging obtains.2, give 1. drying of processing; With substrate material drying, it can be that air dry also can be oven dry, and its fugitive constituent is controlled at 2～3%.2. pulverize: mixing is standby afterwards to carry out fragmentation greater than the material piece of 6 * 6mm in the base-material that drying is crossed.3, hot-forming 1. compacting: the mould that above-mentioned base-material is placed hydraulic press, put into the steel backing that scribbles Bond simultaneously, under 160～170 ℃, unit pressure 18～20MPa condition, suppress 1～1.5 minute/mm, so just obtain the base-material sheet is fixed on disc type blank on the steel backing.2. heat treatment: the disc type blank is piled up on anchor clamps with screw fastening, placed baking oven then, kept 6 hours in 130 ℃～160 ℃, stop heating afterwards, treating that temperature is reduced to can discharging below 60 ℃.4 reprocessings: through spray paint and flour milling after can obtain finished product.
The present invention has following advantage compared to existing technology: pollution and injury that the wet method processing has avoided dust that environment and human body are caused; Stable friction factor, wear-resisting property are good; Do not damage the antithesis of break.
Example 1
Get 5 kilograms of phenolic resin, 15 kilograms of urea formaldehyde resins, they are joined stir 5～10 minutes in the stirrer.Get again 0.5 kilogram of oleic acid, 1.5 kilograms of molybdenum disulfide, 4 kilograms of zine oxide, 6 kilograms of sodium fluorides, 12 kilograms dredge sour barium, 18 kilograms of French chalk, 6 kilograms of plumbagos, 1 kilogram of tyre talc and 18 kilograms of Iron Ore Powder and add successively and stir 15～20 minutes in the stirrer.Still under stirring condition, add 3 kilograms of glass fibres afterwards earlier, add 6 kilograms of Steel Fibres again, add 4 kilograms of copper fibers at last.Continue to stir after all adding to treat that material is loose condition (of surface) and gets final product discharging, what obtain is the substrate material again.Above-mentioned substrate material is placed charging tray, deliver in the drying oven and dry, its volatile constituent is controlled at 2～3%.Place on the disintegrator broken and then sneak into material equably greater than the material piece of 6 * 6mm in the base-material that drying is crossed.Above-mentioned base-material is placed the mould of hydraulic press, put into the steel backing that scribbles Bond simultaneously, under 160～170 ℃, unit pressure 18～20MPa condition, suppress 1～1.5 minute/mm.Be fixed on disc type blank on the steel backing so just obtain the base-material sheet.The disc type blank is piled up on anchor clamps, be placed in the exsiccator, after 130 ℃ are kept 3 hours, be warming up to 160 ℃ again and keep again and stopped heating in 3 hours, treat that temperature reduces to 60 ℃ and get final product discharging with screw is fastening.Again through spray paint, reprocessing such as flour milling can obtain product.
