Abstract

A water-soluble thermosetting acrylate paint for cold-rolled silicon steel is prepared from water-soluble acrylic acid, inorganic solid filler and cross-linking agent through proportionally mixing them together, stirring, adding deionized water for deluting it, homogenizing and sand grinding. Its advantages are high resistance to cold and weather, high adhesion, uniform color, and high antirust performance.

Description

technical field [0001] The invention relates to a subnano-level water-soluble thermosetting acrylate cold-rolled silicon steel coating. The invention belongs to the technical field of paint application. Background technique [0002] So far, there are many technologies and coating formulations for forming an insulating layer on conductive steel sheets. The earliest coatings were mainly chromate and phosphate to form an inorganic film on the conductive steel sheet. Although the inorganic film is excellent in heat resistance, it is poor in water resistance, impact resistance, and adhesion. Recently, in order to solve the above problems, there have been some methods using hybrid coating formulations containing two main components, organic and inorganic. This formulation takes full advantage of the good solderability and heat resistance of inorganic films and the excellent water resistance, insulation, impact resistance and adhesion of organic films. For example, in the coati...
