Problems solved by technology

The main body of water-based metal anti-corrosion paint is an organic product, while the steel structure is an inorganic product. The adhesion between the inorganic product and the organic product is not very strong. Therefore, the current ordinary water-based metal anti-corrosion paint simply applies the paint to the steel structure. On the surface, the protective layer cannot last long, and the old paint film needs to be removed regularly, and the anti-corrosion paint should be repainted, so there is a lot of waste

Abstract

The water soluble anticorrosive paint for metal is prepared with deionized water, titanium white powder, wollastonite powder, kaolin, water soluble fluorocarbon resin, organosilicon emulsion, acrylate emulsion, hydrazyl adipate, film forming assistant and other materials, and through dispersing and mixing. The water soluble anticorrosive paint for metal has high weather resistance, high water resistance, high scrubbing resistance, good adhering performance, great adhesion, capacity of being painted onto rusty surface and wide application range. It may be applied for anticorrosive protection of iron and steel structure in building decoration, petrochemical, bridge, ship, container, etc.

Description

technical field [0001] The invention relates to a metal anti-corrosion paint, in particular to a water-based metal anti-corrosion paint used for anti-corrosion treatment of the surface of metal substrates. The invention also relates to a preparation method of the water-based anticorrosion paint. Background technique [0002] Metal is an indispensable and important engineering material for national economic development and national defense construction, especially steel occupies a larger proportion. However, metal materials are easily damaged by corrosion due to the chemical or electrochemical action of the environmental medium. Therefore, for a long time, people have been devoting themselves to using various technologies to protect metals and prevent corrosion. [0003] The most effective and commonly used metal anti-corrosion method is to coat the metal surface with an anti-corrosion coating to isolate the corrosive medium from the metal substrate. [0004] Most of the t...
