Abstract

The invention provides universal water enamel and a preparation method thereof. The universal water enamel comprises the following components by weight percent: 42-65% of organic silicon modified water acrylic resin, 8-12% of acrylic acid modified water epoxy resin, 10-20% of water, 0.20-0.80% of dispersant, 0.20-0.80% of wetting agent, 0.10-0.60% of flatting agent, 0.20-0.80% of defoaming agent,3-5% of nano talcum powder, 0.20-0.50% of fungicide, 0.5-2% of thickening agent, 2-5% of film forming assistant, 0.30-1% of adhesion promoter, 0.50-2% of rust inhibitor, 0.10-0.50% of pH regulator and 0-10% of water colour paste. The universal water enamel of the invention has high hardness, strong adhesion and good film flexibility, can be applied to multiple substrates and has the characteristics of good levelling property, full and beautiful film and easy construction.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a paint that dries at normal temperature and can be used on the surfaces of metals, medium and low temperature ceramics, glass, plastics, and interior walls, and has high hardness, strong adhesion, and good flexibility of the paint film. Versatile, water-based universal enamel. Background technique [0002] With the improvement of people's living standards, various types of engineering decoration have higher and higher requirements on the environmental protection of decorative materials. Ordinary solvent-based paints contain a large amount of organic solvents, which cause great pollution to the environment and cause harm to the human body when used, which does not meet environmental protection requirements. Therefore, the modern paint industry is working hard to reduce the use of solvents and has developed a high-efficiency paint. Environmentally friendly coatings such as solid content coa...
