Abstract
A preparation method of a coconut carbon compound type brake pad is that the rate of coconut carbon, silicon oxide, carburant, barium sulfate, brown aluminum oxide, vermiculite, carbon fibers, petroleum coke, nitrile butadiene rubber copolymerization modification phenolic resin and steel fibers is 35-45 to 3-5 to 5-8 to 10-12 to 4-5 to 2-5 to 3-5 to 5-7 to 6-8 to 8-10, the carbon fibers in a formula are evenly stirred in a high speed stirring machine to be standby, other raw materials in the formula are arranged in the stirring machine to be evenly stirred, the stirred carbon fibers and other raw materials are stirred together for 5 to 10 minutes, the materials are arranged in a sheet type mould or a disk type mould of a mould machine and then are arranged in a mould pressing machine to be molded and pressed, simultaneously the materials are pressurized and heated for 16 to 19 minutes, pressure is between 14 to 14.5Mpa, temperature is between 130 DEG C to 148 DEG C, pressure is released, the materials are stopped being heated, the mould is taken out, the brake pad is poured out to be ground and polished on a grinding machine to achieve a product.
Description
Technical field
The present invention relates to a kind of brake member of running device, specifically a kind of coconut palm carbon compound type brake pad and preparation method, solve that the hardness that prior art exists is large, damage fastness, noise is large, powder is many, befouling environment and the problem that heat fade is fast, friction factor is unstable.
Background technique
The brake block of current oil field drill, well repairing machine and some large-scale engineering vehicles is mostly have metal brake block, without metal brake block, carbon-base brake sheet and asbestos base brake block, these brake blocks are in operation and mainly contain following shortcoming: have metal brake block too hard, brake failure injures brake assemblage; The little brake of carbon-base brake sheet friction factor is unstable; Asbestos base brake block hardness is too little, working life is short, produce asbestos powder many, befouling environment, metal-free ceramic-type brake plate (patent No.: IL200610068631.2) is although eliminate the defect of above-mentioned brake block existence, it is ideal brake block, but it is many also to there is the selection of material, between proportioning easily produce error, easily produce product performance unstable, in addition purchase material difficult, affect the normal production of brake block.
Summary of the invention
The object of this invention is to provide a kind of coconut palm carbon compound type brake pad and preparation method, overcome the defect that above-mentioned prior art exists.
Technological scheme of the present invention is achieved in the following ways:
Material of preparing of the present invention comprises coconut palm carbon, silica, recarburizer, barium sulphate, Brown Alundum, vermiculite, carbon fiber, petroleum coke, Phenolic Resin Modified By Copolymerizating With Nitrile Butadiene Rubber and Steel Fibre, and its mass fraction ratio is: coconut palm carbon: silica: recarburizer: barium sulphate: Brown Alundum: vermiculite: carbon fiber: petroleum coke: Phenolic Resin Modified By Copolymerizating With Nitrile Butadiene Rubber: Steel Fibre=35-45:3-5:5-8:10-12:4-5:2-5:3-5:5-7:6-8:8-10;
Preparation method of the present invention is: first by coconut palm carbon: silica: recarburizer: barium sulphate: Brown Alundum: vermiculite: carbon fiber: petroleum coke: Phenolic Resin Modified By Copolymerizating With Nitrile Butadiene Rubber: the carbon fiber in the formula of Steel Fibre=35-45:3-5:5-8:10-12:4-5:2-5:3-5:5-7:6-8:8-10 stirs stand-by in homogenizer, again other raw materials in formula to be placed on after stirring in stirrer and again the carbon fiber after stirring to be put together stirring, stir taking-up in 5-10 minute, place it in chip mould on mould bed or disk mold, then be placed on mold pressing in moulding press, pressurized, heated simultaneously, pressure is between 14-14.5Mpa, temperature is between 130-148 DEG C, maintain 16-19 minute, release stops temperature, take out mould, pour out brake block, on grinding machine, namely finishing polishing makes product.
Compared with the prior art the present invention has the following advantages:
1, quality is light, and not water funk, heat fade is little, stable friction factor, long service life;
2, adopt coconut palm carbon to be main raw material, Surface gap degree increases, and noise is little, does not produce powder, free from environmental pollution;
3, be applicable to the friction catch of rig, well repairing machine and mining machinery, Security is high.
Embodiment
For disclosing technological scheme of the present invention further, be described further below in conjunction with embodiment:
Preparation method of the present invention is: first by coconut palm carbon: silica: recarburizer: barium sulphate: Brown Alundum: vermiculite: carbon fiber: petroleum coke: Phenolic Resin Modified By Copolymerizating With Nitrile Butadiene Rubber: the carbon fiber in the formula of Steel Fibre=35-45:3-5:5-8:10-12:4-5:2-5:3-5:5-7:6-8:8-10 stirs stand-by in homogenizer, again other raw materials in formula to be placed on after stirring in stirrer and again the carbon fiber after stirring to be put together stirring, stir taking-up in 5-10 minute, place it in chip mould on mould bed or disk mold, then be placed on mold pressing in moulding press, pressurized, heated simultaneously, pressure is between 14-14.5Mpa, temperature is between 130-148 DEG C, maintain 16-19 minute, release stops temperature, take out mould, pour out brake block, on grinding machine, namely finishing polishing makes product.
