Embodiment 1

[0022] A kind of corrosion-resistant epoxy resin paint, it is made up of the raw material of following parts by weight (kg):

[0023] E-20 epoxy resin 132, modified phenolic resin 25, 1,2,3-benzotriazole 1, polyacrylic acid 2, ethylene glycol 12, pentaerythritol triacrylate 4, N-2-(aminoethyl )-3-aminopropyltrimethoxysilane 0.8, polyethylacrylate 1.2, tert-butyl peroxybenzoate 0.4, emulsifier OP-10 0.6, defoamer polydimethylsiloxane 0.1, dodecane Dimethyl tertiary amine 0.8;

[0024] The preparation method of the modified phenolic resin is as follows: add 5 kg of phenolic resin to 18 kg of styrene and 4 kg of methanol, heat at 75-85°C until the phenolic resin is completely dissolved, and then add 4,4′-di 2 kg of phenylmethane diisocyanate, 2 kg of polyacrylate, 2 kg of acrylic acid, 1 kg of vinyltrimethoxysilane, 1 kg of dioctyl sebacate, 0.5 kg of sodium dodecylbenzenesulfonate, sodium persulfate 0.2 kg, stirred evenly and reacted for 0.9-1.2 hours to obtain modified phenol...

Abstract

The invention discloses corrosion-resistant epoxy resin paint. The corrosion-resistant epoxy resin paint comprises the following raw materials in parts by weight: 132-145 parts of E-20 epoxy resin, 21-25 parts of modified phenolic resin, 18-24 parts of 1,2,3-benzotriazole, 2-3 parts of polyacrylic acid, 1-3 parts of ethylene glycol, 2-4 parts of pentaerythritol triacrylate, 0.8-1 part of N-2-(aminoethyl)-3-aminopropyl trimethoxysilane, 1-1.2 parts of poly(ethyl acrylate), 0.2-0.4 part of tert-butyl peroxybenzoate, 0.6-1 part of emulsifier OP-10, 0.1-0.2 part of defoaming agent poly(dimethylsiloxane) and 0.5-0.8 part of dodecyl dimethyl tertiary amine. The corrosion-resistant epoxy resin paint disclosed by the invention adopts an aqueous emulsion finished product prepared from the modified epoxy resin as a main film-forming substance, the whole production process is smooth and easy to control, the consistency of the finished product is greatly improved, and the batch stability is good; and the ethylene glycol and the pentaerythritol triacrylate are selected as solvents, the odor of the product is greatly improved, and the environmental pollution in production and use is reduced.

Description

technical field [0001] The invention mainly relates to a corrosion-resistant epoxy resin paint, 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, and 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: common industrial phenol and xylene are used as solvents, which have a strong smell, strong irritation, and pollute the environment; it is difficult to control the molecular weight during the synthesis process, resulting in uneven paint quality batches and affecting batches Stability; the process range is small, and the furnace temperature / speed has a great influence on the application of coated wire rods, which has high requirements for coating applications, and it is difficult to form a smooth surface; the adhesion...
