Abstract
Thermal aging exprirnents at different temperature were carried out on two types of water-soluble and extra-thick insulation coatings for non-oriented silicon steel? And a series of test methods such as glossmeters, TG-DTA, FT-IR, GDS, SEM were applied in analysis. For evaluating the thermal aging effect of this kind of insulation coating, the proper temperature range was proposed. The difference of aging performance between two coatings was been investigated and the related behaviors were been discussed. The results indicate that the adhesion of coatings decreases with increasing thermal aging time. During the thermal aging,the fourier transfor infrared studies reveal that the chemical bond created by cross-linking reaction does not break, and the rupture of tridzine ring of amino resin is regarded as the main facor to destroy the three dimensional hydrophobic ploymer network.关键词
