Abstract

The invention discloses an epoxy resin composite material with corrosion-resisting and wear-resisting properties. The epoxy resin composite material with the corrosion-resisting and wear-resisting properties is characterized by being prepared from the following raw materials in parts by weight: 50-56 parts of o-cresol formaldehyde epoxy resin, 20-25 parts of polypropylene glycol diglycidyl ether, 1.2-2.3 parts of diaminodiphenylmethane, 2-3 parts of oyster shell powder, 1-3 parts of sodium carbonate, 1-2 parts of calcium aluminate, 2-4 parts of zinc borate, 5-7 parts of phthalic anhydride, 9-11 parts of diphenyl silanediol, 8-10 parts of polyvinyl butyral, 6-9 parts of polyesteracrylate, 2.1-3.5 parts of 3-diethylaminopropylamine and 3-6 parts of auxiliaries. The epoxy resin composite material with corrosion-resisting and wear-resisting properties can be used for effectively solving the problem that the traditional epoxy resin is single in properties, epoxy resin prepared by utilizing the epoxy resin composite material with corrosion-resisting and wear-resisting properties has the advantages of resistance to chemical corrosion, wear resistance, ageing resistance, high strength and the like and can be widely used for manufacturing anticorrosive materials for different applications, so as to adapt to the working condition environment that the modern industrial equipment and spare parts are complex.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an epoxy resin composite material with both corrosion resistance and wear resistance and a manufacturing method thereof. Background technique [0002] Epoxy resins generally refer to organic compounds containing two or more active epoxy groups in the molecule, which can cross-link with various types of curing agents to form insoluble and infusible three-dimensional network structures. polymers. With excellent electrical insulation, mechanical, bonding, chemical corrosion resistance and good physical and chemical properties, it is widely used as laminates, adhesives, coatings, etc., and is more and more popular in the fields of ships, automobiles, aerospace, etc. Pay attention to. [0003] At present, epoxy resin is used as the matrix of composite materials, showing many problems, such as low hardness, poor insulation, softening by heat, easy delamination, difficult ma...
