However, the conventional wear-resistant rubber sheet has the following problems in use:
in the process of woolen carding of carding machine equipment, a certain amount of wool blending emulsion is added into the mixed material, when the twisting plate twists the divided small wool strips, the rubbing plate contacts with the wool blending emulsion on the small wool strips for a long time and twists the small wool strips into smooth, tight and round rough yarns through reciprocating motion, and then the rough yarns are output to a winding roller for winding through the reciprocating motion, and the fabric is provided with various oil solutions. When the rubber plate manufactured according to the existing formula is used, the rubber plate is not contacted with chemical oil resistant agent to cause the swelling of the rubber plate, so that the hardness of the rubber plate is lowered, the twisting effect is poor, and the service life of the rubber plate is short.
