The invention discloses an impregnated aramid rubber-based special material, comprising raw aramid short fibers, natural rubber, carbon black, stearic acid, zinc oxide, accelerator, silicone powder, quartz powder, molybdenum disulfide and sulfur, Also disclosed is a preparation method for impregnating aramid rubber-based special materials, including the following preparation steps: step 1: shearing; step 2: pretreatment; step 3: irradiation grafting; step 4: dipping; step 5: preparing mixed rubber mixing; step 6: preparation of semi-finished product impregnated aramid rubber-based special material; step 7: vulcanization. The invention improves the technical problems of poor wear resistance and low mechanical strength of the composite material of aramid fiber and rubber in the prior art, and has the advantages of improving the wear resistance and mechanical strength of the composite material of aramid fiber and rubber. |
