1200 Mesh Silicon Carbide Corona Protection Varnish with Epoxy/OMMT Nano-Composite Adhesive

Abstract:

In this paper, a new corona protection varnish was prepared by using epoxy/montmorillonite nanocomposite and pure epoxy resin as adhesive respectively. The adhesive with different amounts of organic montmorillonite (OMMT) was mixed with 1200 mesh silicon carbide (SiC) by different weight ratios. The surface states of the varnishes with various adhesive were observed by powerful light microscope. Some properties of the varnishes were analyzed under DC, such as the relation of change in nonlinear coefficient and natural surface resistivity. The results showed that the amounts of OMMT had little effect on the natural surface resistance of the varnish but it had important influence on the nonlinear property of the varnish. When the range of the OMMT content was 2wt% to 6wt%, the nonlinear coefficient of all materials with epoxy/OMMT nanocomposite adhesive was higher than that with pure epoxy resin adhesive.
