Description
Technical field
The present invention relates to the car brake new material technology field, especially relate to environment protection type fast car brake block and warm-pressing technology thereof.
Background technique
Along with high development of social economy, China has entered the car epoch, and particularly a series of economic policies of government's appearance provide bigger development space to market for automobiles; Along with developing rapidly of market for automobiles, people pay close attention to every performance, the especially braking ability of car more and more, because of it is directly connected to person for driving a car and rider's life safety.The braking ability of car then is that the braking system by car realizes, this shows the significance of car brake system.
The braking system of car is by four most of compositions such as brake oil pump, braking clamp, brake block, brake discs, and the fine or not direct relation of brake block performance reliability, stability and the Security of automobilism.This brake pad of car is made up of steel backing, friction material and annex, and this friction material is bonded on the steel backing, and brake pad of car is installed on the car by braking clamp.At present, the brake block that is used for car brake mainly contains following three kinds, and the deficiency of its existence is:
(1) asbestos base brake block: the prescription of asbestos base brake block friction material is framework material with the asbestos fiber mainly, and asbestos content reaches 40%～50%, is the multi-element composite material composition that Bond adds other functional filler again with phenolic resin.Will cause healthy problem because human body sucks asbestos fiber, therefore be used by developed country's restriction.In addition, asbestos base brake block heat is lost serious, the braking of incompatibility car high speed operation.
(2) semi-metallic based brake block: the prescription of semi-metallic brake pad friction material mainly be by Steel Fibre as framework material, phenolic resin is as tackiness agent, iron powder is as anti-wear agent, the multi-element composite material that adds various functional fillers is again formed.Owing to add metallic material in a large number in the semimetal friction material, so its proportion obviously increases with thermal conductivity, and the aggressiveness enhancing to antithesis gets rusty easily, occurs low frequency noise etc.High gravity will increase complete vehicle weight, increases the driving cost.The increase of heat-conducting property will weaken the shearing strength of brake block under the high temperature behaviour in service, and it is dangerous to cause braking.In addition, cross high thermal conductivity also can produce vehicle rapidly in frequent braking a large amount of heat energy and pass to brake valve, make generation bubble and vapour lock in the hydraulic braking pipe, thus the Security when having a strong impact on car brakeing.
(3) organic ceramic base brake block: the prescription of organic ceramic base brake block friction material is that a spot of copper fiber, ceramic fiber, mineral fibre and Kafra fiber are matrix, phenolic resin is as Bond, and the multi-element composite material that adds multiple functionality ceramic material is again formed.Its shortcoming is: inapplicable large-scale SUV vehicle, and cost an arm and a leg, ordinary consumer is beyond affordability.
(4) preparation method of existing brake pad of car mainly is to be main with the dry method batch mixing, wherein moulding process is mainly by the board-like mould production of two step method, this preparation method's shortcoming is: the yield rate of brake block is low, the manufacture cycle is long, manufacturing efficiency is low, the quality instability of product, mechanization degree is not high, and energy consumption is big.
(5) along with the continuous expansion of market for automobiles, our homemade brake block has also had external market for automobiles, for example Europe.The characteristics of European market are to pay attention to the performance of brake block and velocity correlation, because the expressway in Europe is speed limit not generally, particularly the vehicle driving speed of German expressway can reach more than 200 kilometers/hour, the brake block that Here it is uses in Europe must be paid attention to the reason with the velocity correlation performance, therefore just needs us to develop a kind of fast car brake block of suitable European market.
