Water-based amino stoving varnish and preparation method thereof

Abstract

The invention discloses water-based amino stoving varnish and a preparation method thereof, and relates to the technical field of coating compositions. The water-based amino stoving varnish is prepared from, by weight, 25%-40% of water-based polyester resin, 4%-5% of water-based epoxy resin,7%-10% of water-based amino resin, 25%-35% of deionized water, 1.5%-2.5% of pH modifier, 0.3%-0.5% of wetting agent, 0.2%-0.6% of antifoaming agent, 0.5%-1% of dispersing agent, 1%-5% of cosolvent, 10%-20% of pigments and filler, 2%-5% of nanometer aluminum oxide, 0.3%-0.5% of magnesium lithium silicate, 0.3%-0.5% of thickener and 0.5%-0.8% of flatting agent through uniform mixing and stirring. The flatting agent is waterborne, environmentally friendly, good in stability, high in hardness, high in adhesive force, fast in drying, high in gloss retention, excellent in ageing resistance, good in water resistance, convenient to construct, low in cost and free of pollution.

Description

technical field [0001] The invention relates to the technical field of coating compositions. Background technique [0002] The ever-growing modern coating industry has higher and higher requirements for environmental protection. Reducing the discharge of organic solvents not only protects the environment, but also reduces costs, and is more secure for the health and safety of operators. [0003] At present, paints generally use organic solvents as raw materials. This kind of paint will not only cause a large amount of organic solvents to discharge and cause pollution, but also endanger the health of operators, laying a major hidden danger for environmental safety issues. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water-based amino baking varnish and its preparation method. The water-based amino baking varnish is water-based and environmentally friendly, has good stability, high hardness, can be painted in...
