Experiment Study on Vehicle Friction Material Prepared with High Sulfur Anthracite

In order to develop a new access of high sulfur anthracite clean uillization, the paper analyzed the feasibility of No. 15 high sulfur anthracite from Lanyan Coal Company Jincheng Shanxi to replace the high pure carbon powder and the sulfur powder to prepare the vehicle friction material.The coal samples were pre-treate d with the floatation technology and the ash content of the coal samples would be reduced to 5.56%.With the rational formula selected, the samples of the brake disk W ere made with the dry heat pressed forming technique.The friction coefficient was 0.3870 454 and the wear rate was (0.0100.020) x 10-7 cm2/ (N.m) .The friction coeffic ient would have small variation with the temperature varied and could meet the requirements of the national standard GB 5763- 2008 Brake Liner of Vehicle. The results showed that after the ash reduction with the floatation to No.15 high sulfur anthracite from Jincheng, Shanxi could replace the carbon powder and sulfur powder to prep are and produce the brake disks with the designed requirement of the friction performances.
