Abstract

The invention discloses a shock resisting epoxy resin composite material. The shock resisting epoxy resin composite material is characterized by being prepared from the following raw materials in parts by weight: 50-55 parts of TDE-85 type epoxy resin, 1.2-2.7 parts of 2-mercaptobenzothiazole benzimidazole, 1-3 parts of sludge, 2-4 parts of glass fiber, 1.3-2.9 parts of triethoxysilane, 1-2 parts of paris polyphylla, 2-4 parts of antifebrile dichroa, 8-9 parts of octadecyl alcohol, 14-16 parts of optal, 5-7 parts of polyvinyl butyral, 10-12 parts of phthalic anhydride, 0.6-1.1 parts of calcium aluminate cement, 3-5 parts of butyl acetyl ricinoleate, 7-9 parts of trimellitic anhydride, and 4-6 parts of an additive. The preparation method provided by the invention is simple in technology and convenient to operate, and effectively solves the problem that conventional epoxy resin is single in function; the epoxy resin has the advantages of good rigidity, good strength, good impact resistance, no irritant smell, excellent adsorption performance and the like.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an impact-resistant epoxy resin composite material 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 mass and heat transfer, and strong o...
