Waterborne silver powder stoving varnish for surface of hydraulic equipment

Abstract

The invention provides a waterborne silver powder stoving varnish for the surface of hydraulic equipment. The waterborne silver powder stoving varnish is prepared from the following components by percentage: 50 to 60 percent of epoxy modified waterborne acrylic emulsion, 7.2 to 8.6 percent of amino resin, 10 to 12 percent of waterborne aluminum paste, 0.3 to 0.4 percent of dispersing agent, 0.2 to0.25 percent of defoaming agent, 0.1 to 0.15 percent of multifunction additive, 0.5 to 0.55 percent of anti-flash rust agent, 0.5 to 0.7 percent of silver powder directional arrangement agent, 0.15 to 0.2 percent of wetting agent, 0.2 to 0.25 percent of rheological additive, 0.1 to 0.15 percent of bactericide, 0.4 to 1.2 percent of thickening agent, 3.5 to 4 percent of propanediol butyl ether, 3.5 to 4 percent of isopropanol and the balance of deionized water. By using reasonable formula combination and improving a technology, the prepared waterborne silver powder stoving varnish provided bythe invention has excellent mechanical properties; in addition, water resistance, salt mist resistance and volatile oil resistance are significantly improved; besides, the waterborne silver powder stoving varnish has the advantages of high speed of overall drying rate, smooth and uniform coating film, capability of replacing oil paint for use, safety and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of protective paint for the surface of mechanical equipment, in particular to a water-based silver powder baking paint for the surface of hydraulic equipment. Background technique [0002] As the country has higher and higher requirements for environmental protection, the country has successively issued environmental protection laws, "consumption tax", "pollution discharge tax", etc., and some cities have issued policies prohibiting the production and use of oil-based paints. How to realize the development of environmentally friendly coating technology is The most critical moment in the coatings world right now. The coating requirements on the surface of traditional hydraulic equipment are relatively high, requiring high salt spray resistance and volatile oil resistance. In the past, oil-based paints were used, which can no longer meet the modern needs of environmental protection. Therefore, based on the cur...

Problems solved by technology

The coating requirements on the surface of traditional hydraulic equipment are relatively high, requiring high salt spray resistance and volatile oil resistance. In the past, oil-based paints were used, which can no longer meet the modern needs of environmental protection. Therefore, based on the current national It is imperative to develop a water-based baking paint with performance comparable to that of oil-based paint
