| titleOfInvention | A kind of friction plate material and its preparation method and application |
| abstract | The invention discloses a friction sheet material, a preparation method and application thereof. Among the raw materials of the friction sheet material, carbon nanotubes account for 2-6wt.%, spherical graphite accounts for 0.5-1wt.%, and friction-increasing fillers account for 6-10wt.% .%, the friction reducing filler accounts for 6‑10wt.%, the coupling agent accounts for 0.1‑0.50wt.%, the raw rubber accounts for 8‑10wt.%, the resin accounts for 8‑10wt.%, and the continuous fiber accounts for 45~55wt.%, The balance is additives. The carbon nanotubes and spherical graphite surface modified coupling agent are added to conventional fillers, and the friction lining blank is made by winding molding; then the friction lining blank is hot-pressed into a semi-finished friction lining, and finally the semi-finished friction lining is heat-treated , to obtain the vulcanized friction plate material. The synergistic effect of carbon nanotubes, spherical graphite and coupling agent greatly improves the thermal conductivity and heat dissipation performance of the matrix, reduces the high temperature wear rate of the friction plate, and avoids the decomposition of the matrix caused by the accumulation of excessive heat in the friction process. Friction discs "slip" or break. The method is simple in process and easy for industrialized mass production. |
