Abstract

The invention discloses an epoxy resin composite material for an outdoor mutual inductor electrical insulating coating. The epoxy resin composite material is characterized by being prepared from the following raw materials in parts by weight: 55-60 parts of polybutadiene epoxy resin, 1-2 parts of flower seed powder, 2-3 parts of nylon 66 fiber, 3-5 parts of cocinic acid monoethanolamide, 10-12 parts of butanol, 9-11 parts of citric acid, 6-9 parts of methylhexahydrophthalic anhydride, 1.2-3.2 parts of nano-zinc oxide, 0.7-1.2 parts of dipotassium glycyrrhizinate, 0.9-1.4 parts of (3-aminopropyl)trimethoxysilane, 1.3-3.5 parts of methylisothiazolinone, 2.1-3.5 parts of N, N`-diphenylthiourea, 0.8-1.5 parts of isopropyl tri(dioctylpyrophosphate) titanate and 4-7 parts of an auxiliary. The preparation process is simple, the operation is simple and convenient, and the problem that the conventional epoxy resin is single in performance is solved effectively. The epoxy resin provided by the invention has the advantages of excellent physical and chemical property, high-temperature resistance, low-temperature resistance, ultraviolet irradiation resistance, ageing resistance, high hardness, and excellent insulation effect, and is suitable for electrical insulation of outdoor mutual inductors and other electrical equipment.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an epoxy resin composite material used for electrical insulation coatings of outdoor transformers 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,...
