Description
Technical field
The invention belongs to field of new, particularly relate to a kind of carbon fiber reinforced friction resistance material that is applicable to making automobile and train braking sheet and preparation method thereof.
Background technology
Brake facing is the key part that is related to car brakeing security and stationarity.Wide-scale adoption at beginning of the eighties semi-metallic brake pad.The semi-metallic brake pad material can be adjusted frictional behaviour, thermal characteristics and the mechanical property of material within the specific limits by changing prescription and technology.But there are fatal " three heat " defectives such as heat fading, thermal expansion and thermal crack in semi-metallic brake pad in braking procedure, the braking of running at high speed down can produce very heavy spark, and its brake noise is big.Therefore the current micro-metal brake pad that progressively uses both at home and abroad, and pay much attention to the application of carbon fiber brake facing on heavy duty, the vehicle of running at high speed.The patent No. is the Chinese patent of CN1142024 disclosed " carbon fiber strengthens disk-type braking gland of automobile and preparation thereof ", the employing weight ratio is the disk-type braking gland of carbon fiber (5-15%)/glass fibre (15-20%)/steel fiber (0-5%) conjugated fibre hybrid systems preparation, goods have been overcome 300 ℃ of heat fading phenomenons that produced, but it adopts traditional heat-resistant fireproof resin to make tackiness agent, and there is the defective that fragility is bigger than normal, hardness is higher in the product of manufacturing; The patent No. is another Chinese patent of CN1209381 disclosed " rubber multi-component composite brake shoe and a manufacture method thereof ", adopted the composite brake shoe of metal primitive fiber and carbon fiber preparation, be to utilize rubber to be adhesive composition, its thermotolerance is poor slightly, and moulding process is also comparatively loaded down with trivial details.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide the free of contamination novel carbon fiber of a kind of functional, preparation process to strengthen friction resistance material and preparation method thereof.
The present invention realizes in the following manner:
A kind of carbon fiber reinforced friction resistance material, form by fortifying fibre, matrix resin, frictional property regulator, it is characterized in that fortifying fibre is the mixture of carbon fiber, steel fiber and inorganic mineral fiber, matrix resin is the water emulsion modified phenolic resins, and frictional property regulator adopts at least two kinds in barium sulfate, ferric oxide, Z 250, iron trichloride, magnesium oxide, the silicon-dioxide; The weight percent of each component concentration is: matrix resin content 15-30%, reinforced fiber content 30-50%, frictional property regulator are 20-35%.
Above-mentioned carbon fiber reinforced friction resistance material, it is characterized in that steel fiber is at least a in steel fiber, copper fiber, aluminum fiber, cast fiber and the Stainless Steel Fibre, inorganic mineral fiber is at least a in sepiolite fibre, wollastonite fibre, rock wool, sillimanite fiber and the polygorskite fiber.
Above-mentioned carbon fiber reinforced friction resistance material, the weight percent that it is characterized in that each component in the fortifying fibre is carbon fiber 20-35%, steel fiber 20-35%, inorganic mineral fiber 30-50%.
The preparation method of above-mentioned carbon fiber reinforced friction resistance material is characterized in that may further comprise the steps:
(1) compounding process: earlier with water emulsion modified phenolic resins, carbon fiber, steel fiber, inorganic fibre uniform mixing, at least two kinds of compositions that gradation is afterwards added in frictional property regulator barium sulfate, ferric oxide, Z 250, iron trichloride, magnesium oxide, the silicon-dioxide are made molding compound;
(2) preliminary drying operation: with the shredding of molding compound elder generation, then low molecular fugitive constituent is wherein removed, bake out temperature is preferably 100 ± 5 ℃, and the preliminary drying time is 20-40 minute;
(3) suppression process: molding compound is added in the mould pressurized, heated until solidifying and take out product from mould, mold temperature 160-200 ℃, forming pressure 30-35 MPa, molding time 2.0-3.0 minute/millimeter;
(4) postprocessing working procedures: product put into baking oven or vulcanizing oven carry out after fixing or thermal stresses is eliminated in sulfuration, after warm treatment temp at 160-180 ℃, 10 minutes/millimeter aftertreatment time.
In the material prescription system of the present invention, enhancement component adopts carbon fiber and steel fiber and inorganic mineral fiber etc. to mix, carbon fiber antifriction light weight, steel fiber high-strength heat conduction, advantage that the heat-resisting valency of inorganic fibre is low have been given full play to, can form the random crossover network that fiber is barricaded as, guarantee that from microtexture the friction resistance material of making has good braking ability, mechanical property and thermal characteristics.
Resin system of the present invention adopts the water-emulsion-based modified phenolic resins, utilizes the crosslinking reaction between the polymer to realize phenolic resin curing.And when being tackiness agent with the modified phenolic purely, in brake(-holder) block compression moulding process, discharge micro-molecular gas because of phenolic aldehyde generation polycondensation meeting, thereby be easy to blebbing during fabrication and cause the scrap rate height, and aerogenesis such as further polycondensation and heat scission reaction in use can take place in it because of phenolic aldehyde, cause cracking, fall slag and produce yield and split.And not having pollutions such as dust and organism volatilization when adopting water-emulsion-based resin system batch mixing, the low discharge quantity of hot pressing can guarantee that the goods bubbling that do not ftracture, the low splitting gas of use discharge and can guarantee to fall piece, fall slag, yield splits etc.Therefore the material that is made by this method has good braking characteristic and life-time service good reliability.
