Summary: | The invention relates to a one-step modification method of leather scraps as well as a composite material and application thereof. The method comprises the following steps: firstly, modifying and finely crushing leather scraps by utilizing compounds such as a silane coupling agent, sodium hydroxide and urea to obtain modified fine leather scraps; uniformly mixing the mixture with butadiene styrene rubber, isoprene rubber, butadiene rubber, a vulcanizing agent, a vulcanizing aid, an anti-aging agent, a reinforcing agent and the like in proportion; and performing vulcanization molding to obtain the modified fine leather scrap/rubber composite material. The composite material has excellent wear resistance, skid resistance, tear resistance and bending resistance at the same time, waste is turned into wealth, resource reutilization of waste leather waste is achieved, the production cost of the leather scrap modified composite material is obviously reduced, resources are saved, and the leather scrap modified compos |
