For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of composite brake block, calculate by weight, this composite brake block is made by following raw material: 2～4 parts in phenolic resin, 10～15 parts of nitrile butadiene rubbers, 2～5 parts in graphite, 15～20 parts of Steel Fibres, 10～16 parts of mineral fibre, 3～5 parts in silicon carbide, 2～4 parts of iron oxide, 1～3 part in fluorite, 10～15 parts in barite, 13～17 parts in magnesium oxide, 0.5～1.2 part of molybdenum disulfide, 1～3 part in sulphur.
In the above-mentioned composite brake block, described barite fineness is 100 orders, and barium sulfate content is more than 98%.
In the aforesaid composite brake block, described phenolic resin is melamine-cashew nut oil modified alkyd resin, and free phenol ﹤ 3%, polymerization speed are 60～100s under 150 ℃, volatile constituent ﹤ 2%, 95～115 ℃ of softening temperatures.
The preparation process of aforementioned composite brake block may further comprise the steps,
(1), batching: adopt automatic batching system to take by weighing 2～4 parts in phenolic resin, 10～15 parts of nitrile butadiene rubbers, 2～5 parts in graphite, 15～20 parts of Steel Fibres, 10～16 parts of mineral fibre, 3～5 parts in silicon carbide, 2～4 parts of iron oxide, 1～3 part in fluorite, 10～15 parts in barite, 13～17 parts in magnesium oxide, 0.5～1.2 part of molybdenum disulfide, 1～3 part in sulphur, once batching amounts to 120 kg;
(2), banburying: adopt internal rubber mixer earlier phenolic resin, nitrile butadiene rubber to be carried out banburying, add other materials then and carry out banburying, discharging afterwards;
(3), pulverize: the banburying discharging is ground into granular;
(4), compacting: will be ground into granular material and be pressed at hydraulic press;
(5), solidify: the product after will suppressing is put into baking oven and is cured processing, is rapidly heated 120 ℃ from room temperature, and insulation 1h is warmed up to 130 ℃ then, insulation 1h is warmed up to 150 ℃ again, and insulation 4h is warmed up to 180 ℃ again, insulation 4h naturally cools to 80 ℃ then, comes out of the stove.
Beneficial effect of the present invention: compared with prior art, this patent by prescription that adopt to optimize and preparation technology solved existing wind-powered electricity generation brake shoe not oil resistant, crackle, fall the problem of piece and shake, product meets the relevant national standard requirement, has function admirable, braking ability is good, advantages such as long service life.
The present invention is further illustrated below in conjunction with embodiment.
