Abstract
The invention relates to the technical field of brake pads, in particular to a non-asbestos organic brake pad of a high-speed rail. The brake pad comprises, by mass, 15-20 parts of high-temperature-resistant resin, 3-6 parts of organic aramid fiber, 20-23 parts of carbon fibers, 1-2 parts of heat-resistant additives, 1-3 parts of waterproof agents, 3-6 parts of ultra-fine grinding aid, 6-10 parts of cement, 2-5 parts of butyronitrile powder and 3-8 parts of silicone rubber powder. By means of the waterproof agents and the heat-resistant additives, the brake pad has a stable friction coefficient and is free of noise when water exists or in high-temperature, high-speed and high-pressure work conditions, the cement can coagulate when in contact with water, certain bonding strength is produced, and a certain reinforcing function can be performed on a substrate in the high-temperature working condition; as is proved by tests, after the cement is added in the formula, impact strength is improved and wear resistance is improved at high temperature.
Description
Technical field
The present invention relates to brake block technical field, be specifically related to a kind of high ferro without the organic brake lining of asbestos.
Background technique
Along with the develop rapidly of China's science and technology, in recent years, China Transportation Industry has had the tremendous development of advancing by leaps and bounds.China Railway High-speed, through unremitting effort for many years, occupies first place in the world at present.According to incompletely statistics, to 2012, China railways operation mileage reached 110,000 kilometers; Wherein newly-built high-speed railway has reached 1.3 ten thousand kilometers.Along with building up of China " four is vertical " " four horizontal strokes " railway personal rapid transit system comprehensively, China will enter " high ferro epoch " completely.Face development and the manufacturing demand of car load of China's high ferro industry, domestic very most accessory is in addition still needed and by import, just can be guaranteed the normal safe handling of high ferro, particularly high ferro brake safe part.The brake lining that current nearly all (250 kilometers/hour) are above, all dependence on import maintains current running.For example: the Ke Nuoer of Germany, Siemens, the Alstom of France, the Na Botesike of Japan, daily output and Mitsubishi Denki K.K., world-renowned company and the brand such as the Féraud of Britain is many, in occupation of the staple market of China's high ferro accessory, and the production domesticization of high ferro brake safe part becomes the bottleneck that current high ferro develops.
Summary of the invention
Technical problem to be solved by this invention is to provide the high ferro of a kind of Security, travelling comfort and wear resistance aspect superior performance without the organic brake lining of asbestos.
Technical problem to be solved by this invention realizes by the following technical solutions:
High ferro is without the organic brake lining of asbestos, the component of following mass fraction, consists of:
Fire resistant resin 15-20 part, organic aramid fiber 3-6 part, carbon fiber 20-23 part, heat-resisting additive 1-2 part, water-proofing agent 1-3 part, ultra-fine increasing grinding agent 3-6 part, cement 6-10 part, butyronitrile powder 2-5 part, silicone rubber powder 3-8 part.
The better quality umber of each component is:
18 parts of fire resistant resins, 5 parts of organic aramid fibers, 22 parts, carbon fiber, 2 parts of heat-resisting additives, 2 parts of water-proofing agents, 5 parts of ultra-fine increasing grinding agents, 6 parts of cement, 4 parts, butyronitrile powder, 5 parts, silicone rubber powder.
High ferro, without a preparation process for the organic brake lining of asbestos, comprises following process step:
1) batching, batch mixing: weigh by formula requirement, send in plough type batch mixer batch mixing 20 minutes;
2) brake lining backboard is prepared: first with special cleaning machine, clean brake lining back plate surface spot, then with Shot-blasting Machine, carry out ball blast and make brake lining backboard reach the roughness of expection, finally carry out glue spraying processing;
3) hot-forming: by above-mentioned ready material and brake lining backboard, with hot pressing die, in temperature, be 160-170 ℃, pressure is hot-forming under 25MPa, the time condition that is 10min, in the 1-3min starting, exits 3-6 time in hot pressing, then carries out pressurize;
4) heat treatment;
5) chamfering, fluting, electrostatic spraying, mark, riveted joint, installation accessories, packing makes finished product;
6) check, warehouse-in.
The invention has the beneficial effects as follows:
1) use of waterproof additive and heat-resisting additive, makes goods have water and high temperature, at a high speed, have more stable friction factor, noiseless under high pressure operating mode;
2) adding of organic fiber and butyronitrile powder, silicone rubber powder, make the static friction coefficient of product guarantee there is no brake noise and large spark.
3) because of product belong to brake area large, compared with thick product, in pressing process, be easy to because of the deficiency of exitting, material humidity is large, the various reasons such as Resin Flow is large make product foaming after hot pressing and heat treatment, layering and produce waste product, in order to reduce these disadvantages, in trial-manufacturing process, we arrange special-purpose exhaust port on mould, on material, easy damp material is dried in advance, strengthens compacting and deflation time and makes product be able to smooth production.
4) cement water breakthrough has cohesion, produces certain bonding strength, when high temperature, matrix is had to certain strengthening action, and evidence adds in formula after cement, and impact strength improves, and during high temperature, wear resistance is improved.
