[Abstract]:Objective to investigate the effect of different curing processes on the properties of non-oriented environmental protection silicon steel insulation coating and to study the curing mechanism of non-oriented environmental protection silicon steel insulation coating. Methods A new kind of insulating coating liquid for environmental protection silicon steel was prepared. The coating was cured by different curing processes. Neutral salt spray test and electrochemical test were used. The corrosion resistance, electrochemical properties, insulation properties and surface morphology of the coatings were evaluated by the coating insulation resistance measuring instrument and scanning electron microscope, and the effects of the process on the properties of the non-oriented silicon steel insulation coatings were investigated. The curing mechanism of the coating was studied by thermogravimetric differential thermal analysis and infrared spectroscopy. Results when the curing temperature was 400 鈩，
