Researches on high temperature anti-corrosion coating formulation
Abstract
In this paper, a variety of basic components (such as silicate, 20% acidic silica sol, silane-modified silica sol, et cetera.) as the basis ,copper winding black and mica powder as fillers, sodium alginate, clay, montmorillonite as thickener,were prepared into the high temperature resistant anti-corrosion coatings.And studying the basic components of types and dosage on the properties of coatings systematic and comperhensive. The results show that, compared with other basic components 20% of acidic silica sol as the base component of high-temperature corrosion coatings have better performances, its high temperature resistance up to 850 ℃, impact resistance 50KN, adhesion 100% .Its thermostable was enhanced 100% and 45% by comparing with the ordinary and the organic inorganic compound kind of thermostable anticorrosion coatings.
