Abstract

The invention provides an ultra-high molecular weight polyethylene reinforced material and a preparation method thereof. The preparation method comprises the following steps of carrying out three-bath process impregnation, namely carrying out impregnation treatment by using a first-bath impregnation solution, a second-bath impregnation solution and a third-bath impregnation solution. Water-based epoxy resin, dimethyl pyrazole blocked isocyanate and an acidic metal oxidation catalyst are adopted as the first-bath impregnation solution, and a water-based mixture of zinc methacrylate or zinc acrylate and the like is adopted as the second-bath impregnation solution. The second-bath impregnation solution is a mixed solution of an aqueous solution of RF resin produced through condensation polymerization of resorcinol and furfural and one or more latexes in VPL, NRL, CRL and SBRL. According to ultra-high molecular weight polyethylene fibers treated by the method, the interface bonding performance of the fibers and rubber is enhanced after treatment.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an ultra-high molecular weight polyethylene fiber reinforced material and a preparation method thereof. Background technique [0002] The three high-performance fibers in the world today are: aramid fiber, carbon fiber, and ultra-high molecular weight polyethylene fiber. At present, aramid fiber is only produced in a small amount due to technical problems; carbon fiber is still in the stage of testing and primary production, and the product can only be used in wear-resistant Filling and other fields; ultra-high molecular weight polyethylene fiber has high specific strength and high specific modulus, and its specific strength is more than ten times that of steel wire with the same cross section. , including mooring ropes in offshore oil fields to high-performance lightweight composite materials, have shown great advantages, and play a pivotal role in modern warfare and aviatio...
