Abstract

The invention discloses modified aluminum nitride powder toughened epoxy resin composite material. The modified aluminum nitride powder toughened epoxy resin composite material is characterized by being prepared from the following raw materials in parts by weight: 49 to 59 parts of epoxy resin, 2 to 3 parts of aluminum nitride powder, 5 to 8 parts of linseed oil, 1.2 to 3.2 parts of dicumyl peroxide, 0.8 to 1.4 parts of a titanate coupling agent TMC-TTS, 7 to 9 parts of dioctyl sebacate, 8 to 10 parts of diethylene glycol dimethacrylate, 4 to 7 parts of polyvinylpyrrolidone, 6 to 9 parts of 2,5- di-tert-butylhydroquinone, 10 to 13 parts of dipropylene glycol methyl ether, 3 to 5 parts of polyisobutene, 4 to 7 parts of imethylaminopropylamine, and 3 to 6 parts of an assistant. The modified aluminum nitride powder toughened epoxy resin composite material has the advantages that the aluminum nitride powder is taken as a filler and is subjected to surface treatment, meanwhile other effective constituents are mixed and added to the raw materials, epoxy resin prepared is high in hardness, temperature resistance, waterproofness and tenacity, and the performance of a coating prepared from the composite material is greatly improved.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a modified aluminum nitride powder toughened 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 he...
