Description
Technical field
The present invention relates to a kind of automobile brake sheet, be specifically related to a kind of automobile brake sheet and preparation method thereof
.
Background technique
Braking system is safety system important on automobile, and brake member directly can have influence on the reliability of whole braking system.
Brake block bears the larger original paper of pressure in vehicle, and the gross requirement of brake block is: wear-resistant, friction factor is large, excellent heat-shielding performance.Different by manufactured materials, brake block can be divided into sheet asbestos, semimetal sheet, and NAO(is without asbestos organic substance) sheet three kinds.
Asbestos type brake block: its composition 40%-60% is asbestos.The major advantage of sheet asbestos is cheap.Its shortcoming is: 1, asbestos fiber may cause lung cancer.Do not meet modern environmental requirement; 2, the asbestos capacity of heat transmission is poor, usually braking can make heat heap in brake block repeatedly, after brake block heating, its braking ability will change, produce same friction and braking force needs more to touch on the brake number of times, this phenomenon is called as " braking atrophy ", if brake block reaches certain temperature, will cause brake failure.
Semimetal mixture brake block: the coarse Steel Wool of main employing is as reinforced fibers and important mixture.The major advantage of semimetal sheet is: have higher brake temperature because of its good heat conductivity.Its shortcoming is: 1, need higher retardation pressure to complete same braking effect; 2, particularly in low temperature environment, tenor is high large to brake disc wearing and tearing, can produce larger noise simultaneously; 3, braking heat is passed on brake calipers and assembly thereof, can accelerate brake calipers, piston packing and return spring aging; 4, the heat dealt with improperly reaches uniform temperature level, will cause braking atrophy and brake-fluid boiling.
Without asbestos organic substance automobile brake sheet: mainly use glass fibre, aromatic system polyamides fiber or other fiber (carbon, pottery etc.) as reinforcement material.Its major advantage of NAO sheet is: all keep good braking effect at low temperature or high temperature, reduce wear, and reduces noise, extends the working life of brake disc.Represent the developing direction of current brake block.
Summary of the invention
The object of the invention is to provide that a kind of frictional behaviour is good, wear resistance is strong and automobile brake sheet that noise is little and preparation method thereof.
To achieve these goals, the present invention is by the following technical solutions:
A kind of automobile brake sheet, the material of brake block comprises the component of following parts by weight: phenolic resin 5-10, modified resin 5-10, Fanglun 1414 3-5, glass fibre 8-10, graphite 5-12, sepiolite fibre 3-5, Steel Fibre 3-5, aramid fibre 2-3, antimonous sulfide 3-5, calcium carbonate 10-15, mica 2-5, vermiculite 2-5, steel wool 8-10, red copper cotton 5-10, molybdenum sulfide 15-20, barium sulphate 10-15, molybdenum trioxide 8-10, feldspar powder 10-12, hollow aluminosilicate ball 10-20, Frication powder 3-5.
Further, the material of brake block comprises the component of following parts by weight: phenolic resin 7, modified resin 8, Fanglun 1414 3, glass fibre 8, graphite 10, sepiolite fibre 3, Steel Fibre 3.5, aramid fibre 2, antimonous sulfide 3, calcium carbonate 12, mica 3, vermiculite 3, steel wool 10, red copper cotton 8, molybdenum sulfide 15, barium sulphate 12, molybdenum trioxide 8, feldspar powder 10, hollow aluminosilicate ball 15, Frication powder 3.5.
A processing method for automobile brake sheet, comprises the steps:
(1) prepare burden: the material taking brake block by proportioning is prepared burden, mixing time 40min;
(2) hot-forming: adopt hot pressing one-shot forming technique, pressure is 100-200Mpa, hot pressing time 5 minutes, hot pressing temperature patrix 180 DEG C, middle mould 160 DEG C, counterdie 140 DEG C;
(3) heat treatment: heat treatment installation adopts heat treatment box, and treatment temperature is 150 DEG C-180 DEG C, and the time is 4-8h;
(4) grinding: adopt disc grinder, parallelism of products is 0.15mm, and tolerance is for being less than 0.02mm, and material plane degree is 0.1mm, and tolerance is for being less than 0.01mm;
(5) spray: adopt electrostatic painting process, spraying equipment rotating speed is 800rpm, and ambient temperature is 170 DEG C.
Test brake block of the present invention on constant speed testing machine by B5763-2008 standard, it is as shown in the table for result.
As can be seen from the table, brake block friction factor of the present invention is high, friction factor temperature and frictional force large, brake security and sensitivity good, wear rate is low, and that brake block of the present invention is worn and torn is little, and long service life, noise is little.When detected temperatures is higher than 700 DEG C, heat fade phenomenon is not obvious, and braking ability is stablized, and being less than 2.6% when noise is greater than 75db, is zero when being greater than 80db.
Beneficial effect of the present invention:
Modified resin is good as the high temperature resistant frictional property of binder, antimonous sulfide can improve triboabsorption as frictional property regulator, reduce wear, glass fibre, aramid fibre can absorb the noise of braking automobile, Fanglun 1414, glass fibre, sepiolite fibre, Steel Fibre, the work of gaining in strength is played in aramid fibre cooperation, calcium carbonate, mica, vermiculite, calcium carbonate, mica, vermiculite is that mineral filler can improve the thermostability of material and can improve the heat fade performance of material, Frication powder also plays the effect reducing noise, molybdenum trioxide can prevent brake block from heat fade and cracking at high temperature occurring, it is good that above-mentioned each raw material cooperation makes brake block have wear resistance, noise is little, heat fade performance is good, and the feature of long service life.
