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.

Description

【Technical field】 [0001] The invention relates to a paint, in particular to a surface-treated aluminum powder paste imitation metal fluorocarbon paint. 【Background technique】 [0002] In the decoration of the exterior wall of high-rise buildings, there is an imitation metal fluorocarbon paint cured at room temperature, which can meet the conditions of room temperature environment, and through the construction process, it can complete the decoration and protection effect of the hanging panel similar to the aluminum-plastic panel curtain wall, and has excellent weather resistance. , Such as resistance to ultraviolet radiation, wind erosion, chalking resistance to atmospheric corrosion. However, in the application of wall construction, the general imitation metal fluorocarbon paint uses ordinary aluminum powder paste. Under the action of alkalinity on the wall, the aluminum powder or aluminum paste is easily eroded, and the powder and blackening cause decorative effects. Destr...
