Title: INSULATING COATING MATERIAL FOR USE WITH SILICON STEEL
Abstract:
Provided is an insulating coating material for use with silicon steel, comprising the following raw material components in parts by weight: 35-55 parts of an epoxy resin; 15-20 parts of diethyl maleate; 40-50 parts of aluminum dihydrogen phosphate; 5-10 parts of a drier; 2-6 parts of a solid catalyst; 5-8 parts of an insulation additive; 10-16 parts of ethanol; and 40-45 parts of deionized water. Coatings formed after the coating material is applied on non-oriented silicon steel have a highly transparent appearance, and have an excellent insulation, corrosion resistance, adhesion, weldability, and manufacturability, and overcome the shortcomings of chromium-free coatings of stickiness and poor wear-resistance, and can achieve the environmental protection performance of non-oriented silicon steel coatings.
