Abstract
A pseudo-metallic fluorocarbon paint adopts polymer or inorganic substance-coated aluminum paste, solving the problems of darkening and peeling caused by insufficiency of alkali resistance of untreated aluminum powder paste used in the prior art. The pseudo-metallic fluorocarbon paint comprises composition I including hydroxyl fluorocarbon resin, the polymer or inorganic substance-coated aluminum paste, wetting and dispersing agent, cellulose acetate butyrate, anti-settling sagging agent and solvent; and composition II, hexamethylene diisocyanate (HDI) trimer, wherein, the proportion of composition I to composition II is 16-19:1. The pseudo-metallic fluorocarbon paint prepared by using such compositions including polymer or inorganic substance-coated aluminum paste, in such a proportion, has the advantages of extraordinary alkali and color-changing resistance, so in alkaline environment, aluminum powder erosion changes seldom occur. When being applied to building walls for coating protection, the paint has excellent color retention performance.
