Description
Technical field
The present invention relates to automobile brake sheet preparing technical field, and in particular to a kind of high intensity for automobile brake sheet is resistance to
Hot rubber-based composition.
Background technology
With domestic and international auto industry and the fast development of traffic, on the one hand high growth rate is that friction material product carries
Market is supplied；Another aspect speed is improved, and more stringent requirement is proposed to the performance of friction material.It is exactly environmental protection first
It is required that；Then it is exactly should have good coefficient of friction and abrasion resistance properties, there is certain heat resistance and mechanical strength；Finally
It is exactly with market demands, ensures that performance researches and develops more inexpensive brake slice prescription and increasingly becomes trend simultaneously.
Automobile brake sheet is the important component for ensureing ride safety of automobile.The operation principle of brake is mainly to carry out self-friction,
Existing friction material hard particles in Motor Vehicle Braking Procedure easily wear brake disc in braking procedure, so as to reduce automobile system
The Moving plate life-span.Under bad working environments, high temperature is produced in braking procedure, the heat fading phenomenon in braking procedure is caused, jeopardizes driving
Safety.
Simultaneously with globalization resources conservation, environment friendly and pollution-free, low-carbon energy-saving lamp consumption concept popularization, existing car
With brake pad material many challenges are all suffered from from technology of preparing is designed into.With in brake slice prescription to the stone of early application
Cotton reinforcing agent is disabled comprehensively due to effects on environment and health, as asbestos material function preferable alternative materials metallic copper and its
He also increasingly causes extensive concern by heavy metal raw material to the harmfulness of environment and human body.Existed using copper fiber as Heat Conduction Material
Copper can enter in river, underground water with dampening in wear process, jeopardize the mankind and fish life security.Washington state etc. is
Legislation is promulgated, forces copper content in limitation brake block.Simultaneously because heavy metal sulfide containing Sb is in sky caused by brake pad wear
Oxidation reaction can form stable carcinogen in gas, therefore reduce copper and heavy metal component content in brake slice prescription, research
Develop the brake block without copper, heavy metal free content has turned into the trend of international automobile industry development.For this Chinese patent literature
CN106763357A discloses a kind of automobile brake sheet metal material and preparation method thereof, and its material prescription includes following components：Rubber
Glue, metallic fiber, graphite, frictional property regulator, glass fibre, phenolic resin, steel wool, resinoid bond, molybdenum disulfide, oxygen
Change zirconium, cobalt, talcum powder, the prior art by using rubber, metallic fiber, graphite, frictional property regulator, glass fibre,
The materials such as phenolic resin, steel wool, resinoid bond, molybdenum disulfide, zirconium oxide, cobalt, talcum powder are by heating the preparation sides such as hot pressing
Method makes brake block wearability more preferable, has good a heat absorptivity and thermal diffusivity, make it is simple, it is cost-effective, and the formula without copper,
It is heavy metal free, environment-friendly without asbestos.So due in the prior art matrix be rubber matrix cause high temperature decay serious,
It is and largely more high-leveled and difficult with popularization using the valuable raw material such as molybdenum disulfide, zirconium oxide and cobalt powder, holistic cost in the patent.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome prior art due to matrix to be that rubber matrix has high temperature
The defects of decay is serious, and largely using valuable raw material such as molybdenum disulfide, zirconium oxide and cobalt powders in the patent, it is whole
Body cost it is more high-leveled and difficult to promote the defects of, so as to provide a kind of high strength heat resistant rubber-based composition for automobile brake sheet,
Using and preparation method thereof, the formulation cost is cheap, and frictional behaviour performance is excellent.

The operation of step or condition can be carried out.Agents useful for same or the unreceipted production firm person of instrument, being can be by acquisition purchased in market
Conventional reagent product.
It is as follows provided by the present invention for the preparation method of the high strength heat resistant rubber-based composition of automobile brake sheet：
(1) rubber grain material is prepared：
It is put into after terminating by proportion ingredient in banbury and compound is subjected to banburying, internal mixing pass pressure is 0.5-
0.6Mpa, mixing time 5-20min, banburying is crushed after terminating and is granulated, and between particle diameter is about 0.2-1.0mm, the compound rises
Entitled rubber grain material, place stand-by.
(2) the high strength heat resistant rubber-based composition for automobile brake sheet is prepared：
The each component of proportional quantity is weighed respectively, after aramid fiber and barium sulfate filler then are mixed together into 1-5min, then
Remaining compound is added, 2-10min, being sufficiently mixed for each component can be completed.Compound is placed in hot pressing die and suppressed, is suppressed
Pressure is 300kg/cm2, five compactings, five deflation, press time 5-20s, deflation time 5-30s, dwell time 120-
360s, compacting purpose is friction material to be made to be molded according to the shape of mould, at the same after ensureing material compacting density rational
Within the scope of.Then blank is in 200-300 DEG C of solidification 2-5h of heating-up temperature after suppressing.
Embodiment 1-6 composition of raw materials forms
The embodiment 1-6 raw material weights percentage of table 1 forms
The raw material weight percentage composition of the embodiment 1-6 rubber grain material of table 2
Comparative example 1
Automobile brake sheet metal material disclosed in Chinese patent literature CN106763357A embodiments 1, is designated as X1.
Experimental example 1
Using the composition temperature of X1 and embodiment 1-6 made from same test condition test comparison example at 500 DEG C
Within coefficient of friction, compression strain, impact strength, weightless after AK-MASTER experiments, surface is either with or without crackle after experiment
Occur etc., specific data comparison is shown in Table 2.
The impact of performance data of X1 and embodiment 1-6 composition made from the comparative example of table 3
From table 2 it can be seen that the high strength heat resistant rubber-based composition performance provided by the present invention for automobile brake sheet
It is substantially better than X1, it may be possible to the effect to come into force is cooperateed with because each component in the prescription of the present invention generates under specific proportioning,
Found by correction data, it is 0.45 that X1, which is formulated nominal coefficient of friction, and nominal coefficient of friction is higher, and wherein heat fading coefficient is only
0.25, caused by this is due to the universal not heatproof of rubber based formulas, after being improved by new technology, rubber based formulas temperature tolerance improves,
Stable friction factor is between 0.36-0.42.Comparing number simultaneously it has been found that X1 formula compression strains are higher, impact strength is relatively low,
Find that obvious crackle occurs after experiment, cause to timely respond to brake when driving, and hold when brake pressure is excessive
Brake block fracture is easily caused, potential safety hazard be present.Found after AK-MASTER experiments are carried out, X1 formulas are weightless apparently higher than this
Invent the formulation data provided, it was demonstrated that X1 formula service lifes are not so good as formula provided by the invention.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
