Abstract
A kind of asbestos-free brake block provided by the invention, is at least made by the component of following parts by weight: 40-55 parts of fiber, 10-15 parts of resin, 35-45 parts of Frication powder.The present invention also provides the preparation methods of above-mentioned asbestos-free brake block.The non-asbestos brake block is free of asbestos, health environment-friendly, while being turned waste into wealth as Frication powder using the waste of no asbestos clutch surface production, reducing growth cost, reducing waste discharge.
Description
Technical field
The invention belongs to field of automobile parts and components, in particular to a kind of asbestos-free brake block.
Background technique
Asbestos are just utilized as the reinforcement material of brake(-holder) block since initially, since asbestos fibre is with high-intensitive and resistance to
The characteristic of high temperature, therefore can satisfy the requirement of brake(-holder) block and clutch surface.This fiber has stronger tensile energy, very
It can extremely match with advanced steel, and 316 DEG C of high temperature can be born.More importantly asbestos are relatively inexpensive, it be from
It is extract in amphibole ore, and such ore has largely been found in many countries, so asbestos brake piece was once once
Mainstream as brake(-holder) block.
But asbestos brake piece has basically been eliminated now, because it has some serious defects.
Firstly, asbestos are carcinogens by medical field confirmation, acicular fiber is easy into people lung and stops, and makes
At stimulation, the generation of lung cancer, harm health may finally be caused.
Furthermore since asbestos are insulation, the capacity of heat transmission is particularly poor, is generally repeated as heat being made to make using brake
Nearby heap comes movable plate rubbing surface, and after brake(-holder) block heating, its braking ability will decay, if brake(-holder) block reaches one
Fixed temperature, even results in brake failure.
So asbestos brake piece has been unable to meet Hyundai Motor high speed because of the disadvantages of it pollutes environment and poor high temperature stability
The requirement of change, heavy loading, car body lightweight and environmental protection etc..
Summary of the invention
Technical problem: in order to solve the defects of prior art, the present invention provides a kind of asbestos-free brake blocks.
Technical solution: a kind of asbestos-free brake block provided by the invention is at least made by the component of following parts by weight:
40-55 parts of fiber, 10-15 parts of resin, 35-45 parts of Frication powder.
Preferably, the resin is nitrile rubber and/or cashew nut oil modified alkyd resin.
Preferably, the byproduct that the Frication powder produces for no asbestos clutch surface, i.e., it is raw without asbestos clutch surface
The mill of production is grey (being waste in the past).
The present invention also provides the preparation methods of above-mentioned asbestos-free brake block, comprising the following steps:
(1) ingredient: each group component is weighed according to above-mentioned formula, and is put into the mixing machine of batch mixer:
(2) it is stirred: after ingredient is put into batch mixer, being sufficiently mixed, discharge is into material storage tube；
(3) compression moulding: having loaded lower mould and be placed on hot press, is then fed into lower mould notch, passes through
Molding in 140~165 DEG C of hot pressing temperature, 16~22Mpa of pressure, 7~10min of hot-press solidifying time, deflates 2 on hot press~
3 times；
(4) solidify heat treatment: the friction plate of compression moulding is put into process control drying box and carries out solidification heat treatment, temperature
Degree section is room temperature~180 DEG C, and temperature rise is 1~3 DEG C/min, is respectively in 120 DEG C, 140 DEG C, 160 DEG C and 180 DEG C soaking times
2h,1h,2h,2h；Cool to room temperature with the furnace；Finishing is carried out by grinding machine to get product.
The utility model has the advantages that non-asbestos brake block provided by the invention is free of asbestos, health environment-friendly, while using no asbestos clutch
The waste of device dough sheet production turns waste into wealth as Frication powder, reduces growth cost, reduce waste discharge.Meanwhile it rubbing
The excellent performance of powder ensure that the performance of product.In addition, reducing the use of blanc fixe in product formula, product is reduced
Specific gravity realizes product lightweight.
