Abstract
A kind of friction plate that is used for motor vehicle and mechanical braking, replace asbestos fiber to make the reinforcing material of friction plate with brucite fiber, and add Steel Fibre, rubber powder, chromite powder, wollastonite, graphite, vermiculite power, resin in right amount, through mixing, carry out hot pressing, grind into finished product.The present invention reaches the harm that health of human body is caused owing to adopt brucite, Steel Fibre to replace asbestos to make the reinforcing material of friction plate thereby eradicated the asbestos dust environmental pollution.
Description
The invention belongs to motor vehicle and mechanical braking control system technical field, specifically a kind of brake friction plate.
Friction plate is one of motor vehicle such as automobile, train, aircraft and the indispensable accessory of various machinery.Along with rapid development of national economy, the consumption of friction plate is increasing year by year.The production main reinforcing material that brake lining adopted accounts for about 50% of friction plate material composition for being asbestos at present.Because the large percentage of asbestos that this friction plate occupies, a large amount of asbestos dust in production and using process has caused pollution to environment, and health is caused great harm.Also there are problems such as hardness height, thermal expansion in this in addition friction plate.Countries in the world are all making great efforts the development asbestos-free friction sheet, in order to replace asbestos friction sheet at present.
The purpose of this invention is to provide a kind of natural mineral fiber and replace asbestos to make reinforcing material, produce the pollution problem of asbestos dust during with solution production and use friction plate production environment and social environment.
The object of the present invention is achieved like this: replace asbestos fiber to make the reinforcing material of friction plate with brucite fiber, and add Steel Fibre, rubber powder, chromite powder, wollastonite, graphite, vermiculite power, resin in right amount, through mixing, carry out hot pressing, grind into finished product.The weight percentage of said mixture material each component is: brucite 10-50%, Steel Fibre 5-15%, rubber powder 3-10%, chromite powder 3-20%, wollastonite 3-20%, vermiculite power 3-20%, graphite 3-15%, resin 15-30%.Optimum weight percentage of the present invention is: brucite 20-40%, Steel Fibre 5-10%, rubber powder 3-10%, chromite powder 5-10%, wollastonite 5-10%, vermiculite power 5-15%, graphite 3-10%, resin 15-30%.
The present invention reaches the harm that health of human body is caused owing to adopt brucite, Steel Fibre to replace asbestos to make the reinforcing material of friction plate thereby eradicated the asbestos dust environmental pollution.The present invention also utilizes containing of brucite fiber self of multiple oxide (shown in the table 1), is furnished with simultaneously multiple friction filler again, thereby reduced the hardness of former friction plate, solved the thermal expansion problem in the using process, made comprehensive friction, the polishing machine of friction plate reach international most advanced level.
To be further described the present invention by embodiment below.
Embodiment 1
Replace asbestos to make the main body reinforcing material with brucite, Steel Fibre, and by following weight percentage adding chromite powder, rubber powder, wollastonite, vermiculite power, graphite, phenolic resin, after fully mixing material is carried out cold moudling after by required specification weighing, the cold mould of compacting is hot-forming by hotpress, be finished product through grinding again at last.The weight percentage of said mixture material each component is: brucite 37%, Steel Fibre 9%, rubber powder 4%, chromite powder 6%, wollastonite 4%, vermiculite power 13%, graphite 7%, phenolic resin 20%.
Embodiment 2
The weight percentage of each mixed material each component of this friction plate is: brucite 28%, Steel Fibre 10%, rubber powder 6%, chromite powder 8%, wollastonite 8%, vermiculite power 10%, graphite 5%, phenolic resin 25%, its production technology is same as example 1.Experimental result is referring to table 2.
Example 3
The weight percentage of each mixed material each component of this friction plate is: brucite 34%, Steel Fibre 7%, rubber powder 8%, chromite powder 6%, wollastonite 10%, vermiculite power 8%, graphite 4%, phenolic resin 23%, its production technology is same as example 1.Experimental result is referring to table 3.
