Yttria-stabilized zirconia ceramic friction material and preparation method thereof
The invention discloses a yttria-stabilized zirconia ceramic friction material and a preparation method thereof. The preparation method comprises the following steps that firstly, modified resin, rubber powder, friction powder and aramid fiber are added into a high-speed dispersion machine according to the mass parts and mixed for 10-20 min at the speed of 1000-2000 r/min, and a resin mixture is obtained; 2, yttrium oxide stabilized zirconia powder, potassium titanate whiskers, mineral fibers, tin sulfide, surface modified graphite, coke, ferric oxide, calcium hydroxide and barium sulfate are added into a high-speed stirrer according to the mass parts and mixed for 0.5-1.5 h at the speed of 400-500 r/min, then the resin mixture is added, mixing continues for 0.5-1.5 h, and a friction mixture is obtained; and 3, a steel backing is subjected to cleaning, shot blasting and glue brushing treatment, then the steel backing and the friction mixture are put into a brake pad mold, the mold pressing condition is 165-175 DEG C/25-27 Mpa/8-10 min, cooling and demolding are conducted, a brake pad is subjected to aftertreatment in a drying oven, the aftertreatment conditions are 120-140 DEG C/1-2 h, 150-170 DEG C/1-2 h and 180-200 DEG C/1-2 h, the temperature is reduced to the normal temperature, and the yttrium oxide stabilized zirconia ceramic friction material is obtained. The friction material obtained by the invention has more excellent wear resistance and more stable friction performance.
