when in use, the convex embossing roller 1, the concave embossing roller 2, the first pressing roller 3 and the second pressing roller 4 are respectively heated to a specified temperature by a heating device; conveying the surface layer fiber material to a position between the convex embossing roller 1 and the concave embossing roller 2, and passing through the convex embossing roller 1 and the concave embossing roller 2 to heat the surface layer fiber material to form a convex part and puncture to form an air hole; the formed surface layer fiber material is conveyed between the concave embossing roller 2 and the first pressing roller 3, and is preheated and pressed with the bottom layer fiber material through the concave embossing roller 2 and the first pressing roller; continuously conveying the bonded limiting material to a concave embossing roller 2 and a second pressing roller 4 for secondary hot pressing to obtain a formed double-layer composite fiber material, and then firstly weighing 120 kg of polyethylene, 15 kg of a coupling agent, 10 kg of a plasticizer, 15 kg of a crosslinking agent, 5 kg of an antioxidant, 5 kg of a lubricant, 15 kg of a friction auxiliary agent and 9 kg of a toughening agent, wherein the coupling agent is gamma-mercaptopropyl trimethoxy silane; plasticizer diethylene glycol monobutyl ether adipate; the cross-linking agent is dicumyl peroxide; the antioxidant is antioxidant 619; the lubricant is ethylene bis-stearamide; the toughening agent is cellulose acetate butyrate; and placing the prepared ingredients into a stirring melting box for melting, and coating the ingredients on the surface of the double-layer composite fiber material.
To sum up: the production method of the wear-resistant resin matrix composite fiber material solves the problems of the prior double-layer non-woven fabric that: the dryness, the air permeability and the three-dimensional effect are required to be improved, and the improvement space is provided; in addition, as the surface layer and the bottom layer are connected by adopting the glue, the glue can be stuck or destroy the raised structure of the surface layer when the two layers of materials are bonded, the glue can bring taste or permeate into the surface of the materials from the inside of the fiber materials to affect ventilation and water absorption, and the glue bonding generally needs a certain standing time and pressure application, so that the problem of the formed three-dimensional effect is more easily destroyed.
