Abstract
The present invention provides a making method of a carbon brake friction plate. Carbon, carbon black, feldspar powder, chromium mineral powder, copper wires, vegetable fiber, etc. are mixed together, and then, are stuck on a braking horseshoe in heat preservation by cold compression, hot compression and heat treatment, or are compressed on the braking horseshoe. The present invention has the advantages of large friction coefficient, less abrasion, quick brake, low noise, no spark production, long service life and no air pollution; particularly, in the high temperature of 250 DEG C, the friction coefficient is 0.49 (the Chinese Standard of motor-dom is 0.15), and the abrasion is 0.54 (the Chinese Standard of motor-dom is equal to or less than 2.00). The carbon brake friction plate is an excellent substituting product for an asbestos brake friction plate.
Description
The present invention relates to the manufacture method of a kind of manufacture method of brake strip, particularly a kind of carbon brake friction sheet.
Currently be the asbestos compacting at China's automobile industry and the used brake strip of drilling well industry and form, the flying dust that is produced in braking process all enters air, is a kind of poisonous carcinogen, and is very harmful to human body.All classified the forbidding product as in the U.S. and Germany.The friction plate that the while asbestos are made produces shortcomings such as heat fade (skidding) and thermal expansion in the time of 250 ℃, influence its working life.
Purpose of the present invention be exactly to provide that a kind of friction factor is big, wearing and tearing are little, to the manufacture method of the free of contamination carbon brake friction sheet of air.
Purpose of the present invention can realize by following technological method: take by weighing following material at first by weight: feldspar powder, particle diameter≤0.074mm 12.4%-21.1% barite, particle diameter≤0.074mm 12.05%-19.4% chromite ore fine, particle diameter≤0.074mm 14.21%-20.24% stearic acid 0.26%-1.29% silicon carbide, particle diameter≤0.149mm 0.26%-1.29% potter's clay, the material diameter≤0.074mm 3.49%-12.05% carbon black 0.65%-2.06% copper wire, Φ 15-19 decimillimeter, the pre-oxygen silk of length≤5mm 0.43%-1.29%, length≤1cm 2.05%-10.76% vegetable fiber 2.15%-5.59% phenolic resin 217 9.18%-17.23% hexamethylenetetramine 0.9%-1.72% phenolic resin 2123, concentration 60% 7.75%-15.5% antimonous oxide 0.09%-0.3% glass fibre 1.29%-2.15%
With above-mentioned mixing of materials, be that 98% alcohol stirs with 45%-65%, the concentration of above-mentioned material gross weight subsequently, extrude, dry, cold moudling, under 50 ℃ of-60 ℃ of temperature, dry, again 14 ℃ ± 5 ℃, the insulation of 1 minute condition of every thick 1mm insulation, with the friction plate bonding after the insulation or be pressed on the system car shoes, subsequently 130 ℃-150 ℃ down insulation got final product in 30 minutes.
The present invention has following advantage: friction factor is big, wearing and tearing are few, the braking spirit, noise is low, does not produce spark, long service life, pollution-free to air, especially its friction factor is 0.49 when 250 ℃ of high temperature, (the automobile industry GB is 0.15), and wearing and tearing are 0.54 (the automobile industry GB is≤2.00), are fabulous Updated products of asbestos brake strip.
