Description

A kind of brake block
The present invention relates to a kind of braking control system of motor vehicle, particularly the braking member brake block.
Original brake block is that raw material is made with the asbestos filled phenolic resin.Because of so it comes filled phenolic resin to the lamination coating that environment pollutes both at home and abroad all with non-asbestos.The raw material ratio of components of non-asbestos brake block is more various at present, and the main distinction is the tackiness agent difference.Generally adopt both at home and abroad based on phenolic resin, it is carried out modification with other organic high molecular compound.The shortcoming of well-known high-molecular organic material maximum is a poor heat resistance, does not satisfy the wear-resisting requirement under the worst hot case condition.The human inorganic compound is arranged in recent years as be used to make the oil-well rig brake block with boron modified phenolic resin, the resistance to heat of goods, heat fade performance are significantly improved than the goods of not modification.But manufacturing process more complicated, cost height with boron modified phenolic resin.It is a lot of easily damaged partss of consumption for automobile brake sheet, and the cost height is inapplicable.
The object of the present invention is to provide the brake block that a kind of cost is low, resistance to heat is good.
Purpose of the present invention can realize by following measure: a kind of brake block is characterized in that; The weight percentage of each component is: hybrid resin 10~30%, inorganic macromolecule compound 12~18%, blanc fixe 15~20% Iron Ore Powder 20~25%, calcium carbonate 5~6%, metallic oxide 2~5%, graphite 3~5%, molybdenum disulfide 1~2%, glass fibre 2~3%, Steel Fibre 2~5%, copper fiber 1%.Hybrid resin is the mixture of urea formaldehyde resin and phenolic resin, urea formaldehyde resin: phenolic resin=1~2: 1.Preferably the weight percentage of each component is: hybrid resin 20%, inorganic macromolecule compound 15%, blanc fixe 15%, Iron Ore Powder 25%, calcium carbonate 5%, metallic oxide 5%, graphite 5%, molybdenum disulfide 1%, glass fibre 3%, Steel Fibre 5%, copper fiber 1%.A kind of preparation method of brake block is characterized in that: carried out the blending and modifying processing in 10 minutes with stirring 5 minutes in phenolic resin and the urea formaldehyde resin input dispersion kneader, inorganic macromolecule compound is dropped into again to stir in the dispersion kneader.
The present invention mainly is with the tackiness agent of inorganic macromolecule compound modified organic polymer resin as brake block.
Raw material of the present invention mainly includes Bond, modifier, filler and reinforcing material.Wherein Bond is the hybrid resin of phenolic resin and urea formaldehyde resin, and its amount ratio is a urea formaldehyde resin: phenolic resin=1~2: 1.Though can reduce cost but can influence the performance of brake block if the urea formaldehyde resin ratio is too high,, can not fall if the urea formaldehyde resin ratio is crossed low brake block cost because the physical property of urea formaldehyde resin is poor than phenolic resin.Above-mentioned hybrid resin accounts in prescription and can effectively other component be combined securely in 10~30% o'clock.Preferably hybrid resin accounts for 20% in prescription.The modifier of above-mentioned hybrid resin is inorganic macromolecule compound such as aluminium vanadine and bentonite clay.They and hybrid resin blend can be with its modifications, because the inorganic macromolecule compound resistance to heat well has pliability again, its higher cohesive force and aging cohesive force can improve the intensity of product, and it can also improve the ductility of tackiness agent and the cost that adhesive attraction can reduce product again greatly simultaneously.Product has noise during hard brake very much if consumption too much solidifies the back, if the very few effect that does not reach modification again of consumption, so inorganic macromolecule compound in prescription, account for 12~18% more suitable.Be preferably in and account for 15% in the prescription.The reinforcing material that the present invention adopts includes glass fibre, Steel Fibre and copper fiber, and they can improve the impact strength of product.Wherein glass fibre also can improve the resistance to heat of product, but consumption is too much unsuitable, can increase the fragility of product too much.Generally in prescription, account for 2~3%, be preferably in and account for 3% in the prescription.Steel, copper fiber also can improve the heat-conducting property of product, and the two has noise as the too hard easy damaged antithesis of consumption fecund product during brake, also can increase cost simultaneously.General Steel Fibre accounts for 2~5% in prescription, the copper fiber accounts for 1% in prescription.Preferably the former accounts for 5% in prescription.The filler that the present invention adopts includes blanc fixe, Iron Ore Powder, calcium carbonate, metallic oxide.Graphite and molybdenum disulfide.Wherein blanc fixe can improve the cohesive force of product, and the too much product of consumption is too hard, and it is 15~20% more suitable generally to account in prescription, preferably accounts for 15%.Iron Ore Powder can be improved the goods heat-conducting property and can reduce cost again, but the too much rapid heat dissipation of consumption also can influence the intensity of product, and it is 20~25% more suitable generally to account in prescription, preferably accounts for 25%.Calcium carbonate (coarse whiting) mainly is the stability that can improve product size, reduces cure shrinkage, also can reduce cost.But consumption too much can influence the intensity of product, and it is 5~6% more suitable generally to account in prescription, preferably accounts for 5%.Metallic oxide such as magnesium oxide, aluminium sesquioxide, it can regulate high molecular flexibility, and it is 2~5% more suitable that consumption accounts in prescription, preferably accounts for 5%.Graphite can improve wear-resisting, the anti-ablation, heat conduction of product, performance such as lubricated, and consumption too much can increase cost and generally account for 3~5% in prescription, preferably accounts for 5%.Molybdenum disulfide can improve the wear-resisting and greasy property of product, and consumption too much can increase cost, generally accounts for 1~2% in prescription, preferably accounts for 1%.
The preparation method of product of the present invention is as follows: 1, mediate 1. and carried out the blending and modifying processing in 10 minutes with stirring 5 minutes in phenolic resin and the urea formaldehyde resin input dispersion kneader, inorganic macromolecule compound is dropped into again to stir in the dispersion kneader.2. filler is dropped in the above-mentioned dispersion kneader together, fully stirred 10 minutes.3. under stirring condition, in above-mentioned dispersion kneader, drop into glass fibre, Steel Fibre and copper fiber successively, stirred 20 minutes.2, it is 1. dry to give processing: with kneaded dry materials, it can be that air dry also can be a drying in the air dry oven about 105 ℃, and decide on the volatile constituent of material time of drying, with feel tack-free till.2. pulverize: the material that drying is crossed is cooled to normal temperature, drops in the shredder and pulverizes, and the granularity that makes material is about 80 orders.3,1. compression molding is suppressed: coating release agent in the mould that Xiang Yure crosses, put into steel backing treated mistake and that scribble Bond, material is placed die cavity, under 160 ℃~170 ℃, unit pressure 18~20MPa condition, suppress 1~1.5 minute/mm, so just obtain material is fixed on semi-finished product disc type sheet on the steel backing.2. heat treatment: pile up on anchor clamps semi-finished product disc type sheet fastening with screw, place baking oven then, rose to 100 through 1 hour and kept 3 hours, rose to 125~130 ℃ again through 30 minutes and kept 3 hours, stop afterwards heating treat that temperature is reduced to can discharging below 60 ℃.4 reprocessings: can obtain finished product through flour milling with after spraying paint.
The product that the technology of the present invention is produced has following advantage:
1, stable friction factor, character of heat-fading is little, and resistance to heat is good.
2, wear rate appropriateness is difficult for the scratch antithesis.
Noise is little when 3, braking.
4, cost is low, and price only is 1/3 of an import like product.
