Abstract
The invention relates to an explosion-proof composite soft brake shoe. The explosion-proof composite soft brake shoe is characterized in that the shoe is made of soft materials without asbestos, phenolic resin and metal power in whole, and made of the following raw materials in percentage by weight: 20 percent of rubber, 12 percent of graphite, 13 percent of carbon black, 10 percent of argil, 5 percent of a dm accelerant, 5 percent of paraffin, 3 percent of sulphur powder, 7 percent of magnesium oxide, 5 percent of zinc oxide, 10 percent of coumarone, and 10 percent of rubber powder; the raw materials are poured into a stirrer to be uniformly stirred and to be prepared into mixture; the mixture is subjected to hot press molding through a die, with the hot press temperature being 180 to 200 DEG C and the time being 20 to 25 minutes; then mold stripping is performed, so that the shoe is formed; the shoe comprises three types applied to trains, motor vehicles under coal mines and tramcars. The shoe is good in wear-resisting property, nontoxic and pollution-free, greatly improves the safety, comfort and wear-resisting property of the vehicles, and can greatly prolong the service life of the vehicles.
Description
Technical field
The invention belongs to a kind of accessory being applicable to train, mine vehicle, electric locomotive and tramcar, particularly to a kind of explosion-proof composite soft skidding brake shoe.
Background technology
At present, the brake brake shoe first generation of domestic train in the prior art, mine vehicle, electric locomotive and tramcar adopts cast iron brake shoe that vehicle is had grievous injury, has spark simultaneously, and winter can produce wheel holding phenomenon.Second filial generation product is to do with phenolic resin that binding agent adds asbestos, iron oxide red, stearic acid, metal powder, brium carbonate are made owing to phenolic resin and asbestos are a kind of harmful substances that can be carcinogenic for raw material, human body is had very big injury by the brake block product therefore produced, asbestos, phenolic resin have been acknowledged as carcinogen, environment is not only caused serious pollution by the dust of asbestos, and can be very big to the health hazard of human body, phenolic resin does friction material with asbestos and there is also the phenomenons such as hardness height, easily expansion, easy decline in performance.
Summary of the invention
Instant invention overcomes the defect of above-mentioned existence, purpose is for train, mine vehicle, electric locomotive and tramcar, there is provided one to have noiselessness, to wheel fanout free region, no-spark produces, sleet sky is braked, non-slip i.e. not wheel holding etc., can greatly improve the service life of vehicle, non-toxic and non-pollution explosion-proof composite soft skidding brake shoe.
The present invention explosion-proof composite soft skidding brake shoe content Description:
The explosion-proof composite soft skidding brake shoe of the present invention, it is characterized in that: overall employing is made without asbestos, soft material without phenolic resin, without metal powder, percentage ratio by weight, adopt: rubber 20%, graphite 12%, white carbon black 13%, potter's clay 10%, dm accelerator 5%, paraffin 5%, Cosan 3%, magnesium oxide 7%, zinc oxide 5%, ancient Malong 10% and rubber powder 10% are raw material, being put into by raw material in blender stirs makes compound, compound is undertaken hot-forming by mould, hot pressing temperature 180～200 DEG C, 20～25 minutes time molded and is molded as；Explosion-proof composite soft skidding brake shoe is divided into train explosion-proof composite soft skidding brake shoe, coal mine under well electric locomotive explosion-proof three kinds of forms of composite soft skidding brake shoe of explosion-proof composite soft skidding brake shoe and tramcar disc type.
The explosion-proof composite soft skidding brake shoe of train be shaped as circular arc friction piece 1, friction piece 1 is overall circular shape.
