  The present application discloses a method for making a rubber blade. The method includes applying a first coating composition and a second coating composition in separate steps on at least a part of a surface of a polyurethane elastic substrate; and solidifying the first coating composition and the second coating composition by ultraviolet light irradiating to form a hardened layer on the surface of the polyurethane elastic substrate. The first coating composition includes an isocyanate-group-terminated polyisocyanate and a first solvent. The second coating composition includes a first monomer, a photoinitiator, and a second solvent. The first monomer is at least one of an acrylate monomer and a methacrylate monomer each having an reactive hydroxyl group. The isocyanate group of the polyisocyanate is reacted with the reactive hydroxyl group of the first monomer to generate a urethane group to form a polyurethane acrylate. The present application also discloses a rubber blade.

  本申请公开了一种制造橡胶刀片的方法。该方法包括在聚氨酯弹性基材表面的至少一部分上以单独步骤涂敷第一涂层组合物和第二涂层组合物；以及通过紫外线照射使第一涂层组合物和第二涂层组合物固化，从而在聚氨酯弹性基材表面形成硬化层。第一涂料组合物包括异氰酸酯基团封端的多异氰酸酯和第一溶剂。第二涂层组合物包括第一单体、光引发剂和第二溶剂。第一单体是丙烯酸酯单体和甲基丙烯酸酯单体中的至少一种，每种单体都具有活性羟基。多异氰酸酯的异氰酸酯基团与第一单体的活性羟基反应生成氨基甲酸酯基团，形成聚氨酯丙烯酸酯。本申请还公开了一种橡胶刀片。
