Description
Affiliated technical field
The present invention relates to the manufacture method technical field of mineral fibre, especially a kind of manufacture method of rockwool coating resin.
Background technology
Asbestos are as a kind of natural mineral fiber, and therefore characteristics such as have light weight, inexpensive, good dispersity, friction and wear behavior is good, reinforced effects is good have obtained using widely in friction materials.From 20 1 eighties of last century, asbestos-based friction material almost is to rule all the land.Since the seventies in last century, after asbestos and pyrolytic decomposition thing thereof were identified and belong to carcinogenic substance, many countries had all made concrete regulation to the use of asbestos.The automobile that Switzerland and Germany's regulation were produced in 1988 can not use asbestos-based friction material.Also there is the motion that bans use of asbestos in 10 years in the U.S..Meanwhile, the strictness of asbestos dust restriction must be carried out the great number investment to dust removal installation, causes the asbestos friction material price to rise.Along with the progress of auto technology, the speed of automobile is more and more higher, and stopper is littler, and the appearance of disc brake, and to the demands for higher performance of friction materials, working conditions is also more harsh.Nowadays car front-wheel disc type brake temperature can reach 300～500 ℃, and asbestos will lose crystal water about 400 ℃, and crystal water will completely lose in the time of 580～700 ℃, also follows the string and intensity simultaneously, loses reinforced effects substantially.Cause the frictional behaviour instability, damage antithesis and brake oil occurs after the asbestos dehydration, therefore, asbestos-based friction material obviously can not adapt to automotive industry and modern social development's demand will progressively be substituted.Because the backwardness that China's level of economic development is lower, common people's environmental consciousness does not reach automotive industry by force, the asbestos-based friction material that price is lower, range of application is wider are also being used so far.Yet along with the fast development of Chinese national economy, the improving constantly of living standards of the people, people are also more and more higher to requirement on environmental protection.The national departments concerned regulation, asbestos-based friction material will be substituted by other fiber reinforcement composite friction material in recent years.The effect of fortifying fibre mainly is to make material have certain intensity and toughness in the friction material reinforced, mechanical effect such as shock-resistant, shearing, stretching and be unlikely to occur crackle, rupture, collapse physical abuses such as scarce.Therefore fortifying fibre should satisfy following performance requriements: 1. have enough intensity and modulus and toughness preferably; 2. good frictional behaviour has stable frictional coefficient and suitable frictional dissipation in certain temperature range; Thermolysis, dehydration, phase transformation etc. and higher pyrolytic decomposition carbon residue rate do not take place in 3. higher heat decomposition temperature in certain temperature range; 4. fiber is easy to disperse and with matrix intermiscibility is preferably arranged; 5. suitable hardness does not produce serious noise; 6. measure wide, inexpensive, nontoxicity, free from environmental pollution.
At present, carried out the research that substitutes fortifying fibre both at home and abroad.Mainly contain steel fiber, glass fibre, carbon fiber, organic fibre.Though have so numerous fortifying fibres that substitutes, non-asbestos fiber also exists many deficiencies; 1. the intermiscibility of fortifying fibre and matrix is relatively poor; 2. price exceeds much than asbestos-based friction material; 3. the finished product performance of fortifying fibre friction materials is not very stable, though the substitute fibre friction materials has surmounted asbestos-based friction material in some aspects, also has bigger gap with regard to overall performance.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of manufacture method of rockwool coating resin, utilize the rockwool coating resin low price of this method manufacturing, the noise that can reduce friction materials and vibration, good with the intermiscibility of matrix, frictional behaviour is good.
The present invention solves technology and the case that its technical problem adopts: a kind of manufacture method of rockwool coating resin has following processing step:
A. pulverize; Basalt or slag are pulverized, each composition weight percent content of basalt or scoriaceous chemical composition is silicon-dioxide 40～45%, aluminium sesquioxide 7～9%, calcium oxide 32～38%, magnesium oxide 6～9%, other inorganicss 5～8%, and the breeze after the pulverizing requires to reach 40～60 orders;
B. high temperature melting; With the breeze fusion in induction furnace or resistance furnace after pulverizing, temperature of fusion is 1300 ℃～1800 ℃;
C. spray silk; Melt is got rid of silk with four roller whizzers become rock wool fibers; Fibre diameter is 1～10 μ m;
D. spray glue; Spray resol in rock wool fibers surface is got rockwool coating resin, spray bondline thickness 0.02 μ m;
E. cut; Rockwool coating resin after the processing of spray glue is cut, be cut into long 0.5～1.0mm;
F. screening; Rockwool coating resin after cutting is screened, and screening criteria is 0.5～1.0mm for rockwool coating resin length;
G. pack; Pack screening qualified rockwool coating resin.
The invention has the beneficial effects as follows that the rockwool coating resin that utilizes the present invention to make has following advantage:
1. friction and wear behavior is good.The raw material sources of rockwool coating resin are in the slag of basalt or steel-making, and the hardness of its product is lower than wollastonite, chemical ingredients circle between asbestos and wollastonite and glass bigger difference is arranged, the friction and wear behavior of rockwool coating resin also is different from glass fibre and wollastonite.Glass fibre and wollastonite polishing machine are bigger, and frictional behaviour is better, is easy to generate brake noise, and the polishing machine of antithesis is also bigger.Because rockwool coating resin has lower second-order transition temperature, therefore in the braking procedure of disc brake pad, because brake pressure is big, therefore the speed height produces than higher brake temperature, can reach more than 700 ℃, under all situations, surpassed the second-order transition temperature of rockwool coating resin, can play the effect of certain inorganic binder like this, can reduce the consumption of tamanori, lower tamanori consumption can improve heat fading.The rockwool coating resin wear resistance is better than glass fibre and wollastonite, and spray glue is handled and the consistency of other resins and filler is good, stable friction performance because the rockwool coating resin surface has been done; Rockwool coating resin is compared with steel fiber, and thermal conductivity is lower than steel fiber, can reduce the temperature at the brake facing back side.
2. low price.
