Abstract

The water soluble inorganic zinc paint consists of two components, component A and component B, in the weight ratio of 1 to 1.5-4. The component A is prepared through mixing alkali silicate, water soluble resin, nano colloid solution of inorganic oxide and silane as cross-liking agent under stirring for reaction to obtain sol; ageing the sol to obtain gel; adding pure water, inorganic pigment, alkali water solution and water soluble defoaming agent; and grinding. The component B is prepared with spherical zinc powder, chip metal powder, alkali-resisting inorganic pigment and stuffing, wetting carboxylate dispersant and through mixing. The paint has good early stage water resistance, high slipping resistance and high salt mist corrosion resistance, and the production process has no waste water, slag and waste gas produced and is environment friendly.

Description

Technical field [0001] The invention relates to a water-based paint and a manufacturing method thereof, in particular to a water-based two-component inorganic zinc paint and a manufacturing method thereof. The paint is particularly suitable for the protection of high-strength bolt connection surfaces and can also be widely used for the corrosion protection of steel structures. Background technique [0002] Water-based inorganic zinc-rich coating is one of the few excellent coatings that can protect steel structure and make it have a corrosion resistance life of more than 10 years. It achieves corrosion resistance through electrochemical action, that is, anode action. Its coating film is very hard and wear-resistant, has excellent chemical resistance within a certain pH range, and can withstand high temperatures up to 400°C. It can be used as a single long-lasting protective coating or as a primer for high-performance coating systems. Since the 1970s, it has been used more and mor...
