Abstract

The invention relates to an environment-friendly aqueous fluorocarbon metallic paint, consisting of the following raw materials in the following percents by weight: 35-65 percent of fluorocarbon emulsion, 5-12 percent of aluminum paste, 0.1-0.5 percent of antifoam agent, 0.1-0.3 percent of wetting agent, 0.1-0.3 percent of leveling agent; 0.2-0.8 percent of dispersing agent, 2-8 percent of metal orienting agent, and 0.1-0.3 percent of thickener: organic modified montmorillonite, 1.0-5.0 percent of polyurethane associative thickening agent, 1-3 percent of film forming agent, 1-3 percent of anti-freezing agent, 6-10 percent of solvent, and deionized water as the rest. The environment-friendly aqueous fluorocarbon metallic paint can reduce environmental pollution and application risks in thermal-insulation decoration systems and the performance can equal to that of solvent-based fluorocarbon aluminum paste (pearl powder) coating.

Description

Environment friendly water-soluble metal fluorocarbon coatings

Technical field

The present invention relates to a kind of metallic paint, relate in particular to a kind of metallic paint that is applied to decorating outer wall of building and outer insulation and decoration system.

Background technology

Fluorocarbon coating is with its super-weathering resistance, high-decoration, endurance, resistance to soiling, decorating outer wall of building and outer insulation and decoration system have been widely used in, especially fluorine carbon aluminium-silver slurry (pearly-lustre) coating is with its lower cost, high-decoration and substitute expensive metal curtain wall gradually, but VOC is higher because of solvent-borne type fluorine carbon aluminium-silver slurry (pearly-lustre) lacquer, contaminate environment, and in external wall heat insulation system, because of the lagging material poor solvent resistance, solvent based coating has the risk of destroying thermal insulation layer, and its use is restricted.

Summary of the invention

The technical issues that need to address of the present invention have provided a kind of environment friendly water-soluble metal fluorocarbon coatings, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

The present invention is made of by mass percentage following raw material:

Fluorine emulsion 35%～65%

Aluminium-silver slurry (pearly pigment) 5%～12%
