Description
Technical field
The present invention relates to a kind of friction materials, particularly, relate to a kind of resin-matrix friction material for brake facing for brake facing.
Background technology
Within 1897, invent first piece of brake facing in the world, and for carriage and early stage automobile, subsequently at invention in 1909 first solidification asbestos base brake facing, nineteen sixty-eight invention first semi-metallic based brake facing in the world, after this, friction materials starts to develop to without asbestosization.The alternative fiber of various asbestos begin one's study both at home and abroad as the application on friction materials such as steel fiber, glass fibre, aramid fiber, carbon fiber.Although the kind of fortifying fibre is a lot, do not have a kind of fiber can replace asbestos completely on cost and performance, therefore domestic and international research has in recent years turned to assorted fibre from Single Fiber gradually.
The Main Function of cakingagent is bonded together by each components in close of brake facing, keeps the structural integrity of brake facing under high-temperature machinery effect.The cakingagent the most often used in brake facing is resol, and it has excellent resistance toheat and mechanical property, electrical insulating property and moulding processability good, and raw material is easy to get, low price, technique and production unit simple.But the use of pure phenolic resin can cause brake facing much higher hard, fragility large, and heat-resistant limit temperature is only about 250 DEG C.When more than 300 DEG C, thermolysis phenomenon is quite serious, and the performance of brake facing can be caused significantly to decline.Therefore must carry out toughness reinforcing and heat resistance modified to resol.
The modified resin abroad used mainly contains Effect of Organosilicon-modified Phenol-formaldehyde Resin, boric acid modified resol, hydrocyanic ester modified phenolic resins, epoxy modified phenolic resin etc.The brake facing wherein utilizing boric acid modified resol to prepare, in 400 DEG C, still keep higher frictional coefficient, but this friction materials cost is higher.
Existing friction materials generally includes a few part of binding agent, strongthener, frictional property regulator, filler and compound, wherein binding agent generally adopts resol to do raw material, its shortcoming existed is: poor heat resistance, and heat decomposition temperature is low, is not suitable for the production of high temperature friction sheet; The cohesive strength of resin is low, and cause the wear rate of friction goods high, work-ing life is short; The poor toughness of resin, vehicle can produce noise, the frangible damage of friction plate when braking; Free phenol content is high, and the friction plate compactness of producing is poor.Such friction materials can not meet market demands.The research of China's brake facing is more late than abroad starting to walk, and also has larger gap with World Developed Countries.
