Problems solved by technology

Water-based acrylic topcoats can meet weather resistance requirements, but the gloss of current water-based acrylic topcoats is lower than that of oil-based acrylic topcoats, and the gloss is generally only 10-20%, which cannot achieve the effect of oil-based topcoats
At the same time, its corrosion resistance and wear resistance have a large gap compared with oil-based topcoats, so it is urgent to develop a new acrylic water-based anti-corrosion topcoat to meet market requirements.

Abstract

The invention discloses a finish paint, particularly provides a water-based anticorrosive finish paint which comprises softened water, water-based polyacrylic emulsion, nano- pigment and filling and other necessary components, with the water-based finish paint with the above components adopted, coating effect of the oily propenoic acid finish paint can be achieved, the waterproofing and anti-corrosion property are good; in addition, the water-based propenoic acid finish paint adopts water as solvent with no pollution to the environment, no harm to health of constructors, and safe and convenient use; can adopts a general spraying method and can also be applicable to high-pressure airless spraying with high construction efficiency, no sagging and no cracking, the finish paint construction can be completed; the water-based propenoic acid finish paint can not only be applied to auto body decoration and protection, but also widely replaces oily propenoic acid finish paint for rust-resisting of steel materials in facilities, such as other vehicles, bridges and channels and the like.

Description

technical field [0001] The invention relates to an acrylic paint, in particular to a water-based anti-corrosion finish paint using an acrylic emulsion. Background technique [0002] In the current automobile industry, the exterior painting of automobiles is a very important process, especially for some vehicles that are returned to the factory for repair after some hang-up accidents, its painting is even more indispensable. The existing spray paint for automobiles, Most of them are solvent-based coatings. Common varieties include epoxy resin, chlorinated rubber, acrylic acid, polyurethane, etc., which contain a large amount of organic solvents. These solvents are harmful to the health of construction workers and pollute the environment, and the cost is relatively high. Foreign countries have begun to develop new anti-corrosion and anti-rust paints that replace organic solvent-based paints since the early 1970s, but due to technical difficulties, no major progress has been ma...
