Abstract

The invention relates to a preparation method of brake pad in the automobile industrial field, in particular to a method for preparing brake pad by utilizing potassium titanate lamella crystal. The technical scheme thereof includes that the brake pad is composed of the following components by weight percent: 5-10% of binder, 15-25% of reinforced fiber, 20-30% of abrasive material, 15-25% of lubricant and 30-40% of regulator. The invention has the beneficial effects that the brake pad processed by adopting the method can well absorb heat energy released by high speed braking and heat conduction of brake pad is reduced. Thus, the brake pad has excellent high temperature brake performance and braking comfort.

Description

Utilize potassium titanate lamella crystal to prepare the method for brake facing
One, technical field:
The present invention relates to a kind of preparation method of auto industry field brake facing, particularly a kind of method of utilizing potassium titanate lamella crystal to prepare brake facing.
Two, background technology:
The primary structure of brake facing is cakingagent, fortifying fibre, abrasive, lubricant and necessary conditioning agent.Its complete processing is as follows: batch mixing, hot pressing, thermal treatment, grinding, spray paint, installation accessories, seal mark packing.
Automotive industry develop rapidly in modern age, the passenger car speed of a motor vehicle is more and more higher.This also requires brake facing not only to have good braking effect, and good heat-resisting effect and good braking comfort property also will be arranged.The ubiquitous problem of brake facing is that product thermal conduction is excessive at present, so braking ability is not very desirable with the braking comfortableness under the high temperature and high speed condition.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, and a kind of method of utilizing potassium titanate lamella crystal to prepare brake facing is provided, and utilizes thermal capacitance is big, resistance toheat is outstanding potassium titanate lamella crystal to improve the resistance toheat of friction materials.Make brake facing in use can be good at absorbing the heat energy that brake is at a high speed discharged, reduce the thermal conduction of brake facing.Reach the purpose that improves the high temperature and high speed braking ability, improves the braking comfortableness.
Its technical scheme is: made by following compositions in weight percentage: tackiness agent 5-10%, fortifying fibre 15-25%, abrasive 20-30%, lubricant 15-25%, conditioning agent 30-40%; Wherein, tackiness agent adopts resol, nbr modified phenolic resins or silicon modified phenolic resins; Fortifying fibre adopts copper cotton fibre and the combination of aramid pulp or the combination of ceramic fiber and aramid pulp; Abrasive adopts the combination of zirconium silicate, iron oxide black, aluminium sesquioxide and friction powder; Lubricant adopts the combination of inorganic lubricant, organic lubricant or metallic sulfide; Conditioning agent adopts the combination of potassium titanate lamella crystal, barium sulfate or lime carbonate.
