Background technology
Friction materials is made up of sticker, fortifying fibre, abrasive material, lubricant and five big types of materials of filler usually.Its function is following:
Sticker: powder body materials such as fortifying fibre, abrasive material, lubricant and filler are bonded together.What generally adopt is resin modified phenol resin.Commonly used has: cashew nut oil modified alkyd resin, nitrile rubber modified phenolic resin, aromatic modified resol and various import high-temperature resin.
Fortifying fibre: in the friction process of friction materials, play a crucial role, can play enhancement and improve the friction and wear behavior characteristic.Fortifying fibre commonly used has: fibrous magnesium silicate, steel fiber, copper fiber, vermiculite fiber, wollastonite fibre, sepiolite fibre, spun glass, ceramic fiber, aramid fiber, thomel, polyacrylonitrile fibre etc.Add fibrous magnesium silicate in the brake material, have characteristics such as snappiness, frictional coefficient are high, cheap, but make and use in atmosphere pollution and carcinogenic.Thomel and aramid fiber have intensity height, a series of excellent properties such as heat-resisting, wear-resisting, corrosion-resistant, are a kind of more satisfactory reinforcing fiber materials, but cost an arm and a leg.Characteristic such as that ceramic fiber has is heat-resisting, frictional coefficient is high, price is low, but poor thermal conductivity is prone to make brake material crackle to occur.Steel fiber have the intensity height, heat-resisting, thermal conductivity good, frictional coefficient height and wide material sources are cheap.
Abrasive material: in friction materials, play the effect of raising and stable high temperature friction coefficient.Abrasive material commonly used has: aluminum oxide, silicon oxide, zirconium sulfate, Calcium Fluoride (Fluorspan), silit, red stone, glass-cermic powder and refractory metal etc.Abrasive material should have sufficiently high physical strength and hardness, guaranteeing in the friction process as much as possible energy expenditure in the breakage of abrasive particle, but can not be too high, otherwise the mating material that worn and torn to a great extent.Globule size to abrasive material also has certain requirement simultaneously, has played not effect too for a short time, the wearing and tearing that then can increase mating material too greatly, even cause noise.
Lubricant: in friction materials, play and reduce friction, improve wear resistance, and play the effect of stablizing frictional behaviour, also help the moulded section of friction materials simultaneously.Lubricant commonly used has: graphite, molybdenumdisulphide, tungsten disulfide, cuprous sulfide, SP 1, ANTIMONY SULPHIDE, Natural manganese dioxide, lead, bismuth, antimony, coke, talcum powder etc.Lubricant is along with the increase of add-on, and wear resistance obviously improves, but frictional coefficient can descend, and the physical strength of material also can descend, so add-on is unsuitable too many.
Filler: not only can improve the physical property of material at friction materials, but also can play the effect of regulating braking effect, suppressing noise and reduce cost.Filler commonly used has; Kaolin, Feldspar Powder, permanent white, lime carbonate, copper scale, silica powder, tyre powder, rubber powder, wollastonite powder etc.Filler is an indispensable component in the friction materials.
At present, composite friction material be with these above materials according to prescription and processing requirement, prepare according to following steps: the first step: with starting material by filling a prescription weighing, thorough mixing in high speed mixer then.Second step: powder mix weighed put into mould and cold pressing; With or the 3rd the step: hot-forming, guarantee that resin solidification reacts completely.Hot pressing temperature will be confirmed according to the resin solidification temperature, generally more than 140 ℃; Pressure 12-20Mpa; Soaking time is confirmed with size according to the shape of material with the venting number of times.The 4th step: aftertreatment.Confirm post-processing temperature according to the resin solidification temperature, generally more than 140 ℃; Soaking time: 4-24h.The 5th step: mechanical workout, spray paint.Obtain shape, mechanical property, the different composite friction material of friction and wear characteristic.
See that from present bibliographical information people are the improvement of frictional coefficient and polishing machine to the more concern of Study on Friction Materials, and the improvement of various mechanical properties or the like.In order to increase frictional coefficient, need in friction materials, add aforesaid abrasive material, these abrasive materials are generally the higher pottery of hardness; The higher pottery of these hardness can cause scuffing to mating plate when friction materials is worked, particularly when hoping high friction coefficient, people tend to add like these high firmness potteries of silit or the like; Cause the very big scuffing of mating plate; And we know, mating plate generally than high the getting of friction materials cost, is not hoped too early scrapping usually; Therefore, hope a kind of, friction materials that simultaneously again can keep higher coefficient of friction little of exploitation to the mating plate wearing and tearing.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide to the little method for preparing friction of mating plate wearing and tearing.
For realizing above-mentioned purpose, technical scheme of the present invention is following:
A kind of to the little method for preparing friction of mating plate wearing and tearing, said friction materials is made up of following component in weight part: fourth cyanogen modified phenolic resins 16-18 part, aramid fiber 2-3 part; Aluminum fiber 3-5 part, vermiculite fiber 7-9 part, calcium carbonate crystal whisker 5-7 part ,-200 order silicon-dioxide 4-6 parts;-250 order electrofused mullite 3-5 parts; Colloid molybdenumdisulphide 2-4 part, 40-60 order crystalline flake graphite 2-3 part ,-120 order crystalline flake graphite 5-7 parts;-200 orders sulfuration antimony powder 3-5 part ,-200 order permanent white 10-12 parts; Described preparation method is: by each component materials of said ratio content weighing; Fourth cyanogen modified phenolic resins, aramid fiber, aluminum fiber, vermiculite fiber, calcium carbonate crystal whisker, silicon-dioxide, electrofused mullite, permanent white and the ANTIMONY SULPHIDE of weighing put in the mixer mixed about 4-6 hour, put into colloid molybdenumdisulphide, 40-60 order crystalline flake graphite and-120 order crystalline flake graphite remix then about 3-5 hour; Carry out under for about 175-185 ℃ hot-formingly at the about 26-28MPa of pressing pressure, temperature, pressing speed is about 0.1-0.2mm/ second, and exhaust is carried out in the centre; Handle at about 165-185 ℃ of constant temperature then and got final product in about 8-10 hour.
