Abstract

The invention discloses environment-friendly epoxy resin paint for a transformer. The environment-friendly epoxy resin paint comprises raw materials in parts by weight: 118-125 parts of modified epoxy resin, 18-26 parts of phenolic resin, 13-18 parts of alkenyl succinic acid ester, 3-4 parts of phthalate glycol acrylate, 1-2 parts of pentaerythritol triacrylate, 0.3-0.6 part of phenylamine methyl triethoxysilane, 0.3-0.4 part of isopropyl three (dioctyl pyrophosphoric acid acyl oxygen radicals) titanate, 0.9-1.2 parts of polyacrylic acid ethyl acrylate, 1-2 parts of polyacrylic acid, 0.2-0.4 part of benzoyl peroxide, 0.2-0.6 part of 2,6-butylated hydroxytoluene and 0.1-0.2 part of polydimethylsiloxane serving as an antifoaming agent. By the environment-friendly epoxy resin paint, a modified finished product prepared by the modified epoxy resin is used as a main film-forming substance, so that the whole process is stable and easy to control, the consistency of a finished product is greatly improved, and the batch stability is good; and the phthalate glycol acrylate and the pentaerythritol triacrylate are used as solvents, so that the smell of a prepared finished product is greatly improved, and the environment pollution to production and application is reduced.

Description

technical field [0001] The invention mainly relates to an environment-friendly epoxy resin paint for transformers, which belongs to the field of chemical industry. Background technique [0002] Epoxy resin paint is widely used in the manufacture of special coils (such as DY coils, power tool coils, various transformer coils) due to its excellent moisture resistance and deformation resistance. The epoxy resin paint produced by the traditional method has the following defects: the use of common industrial phenol and xylene as the solvent, the odor is strong, the irritation is strong, and the environment is polluted; the synthesis process is difficult to control the molecular weight, resulting in uneven paint quality batches, affecting batches Stability: The process range is small, the furnace temperature / rotation speed is greatly affected when the coating wire is applied, and the coating application requirements are high, and it is difficult to form a smooth surface; th...
