Abstract

The invention discloses waterborne acrylic amino resin silver powder paint and a preparation method thereof, and belongs to the field of chemical paint. The silver powder paint is prepared from the following raw materials in parts by weight: 60 to 70 parts of waterborne acrylate emulsion, 8 to 10 parts of amino resin, 4 to 6 parts of ethylene glycol monobutyl ether, 0.2 to 0.3 part of a de-foaming agent, 0.2 to 0.3 part of a flatting agent, 1.5 to 2.0 parts of an anti-settling agent, 15 to 20 parts of de-ionized water and 8 to 10 parts of waterborne aluminum silver paste. The preparation method comprises the following steps: adding a wetting dispersant and titanium dioxide cladded aluminum powder into the de-ionized water, and stirring to prepare the waterborne aluminum silver paste; then stirring and mixing the waterborne acrylate emulsion, the amino resin, the ethylene glycol monobutyl ether, the de-foaming agent, the flatting agent, the anti-settling agent and the de-ionized water, and adding the waterborne aluminum silver paste to prepare the silver powder paint. The waterborne acrylic amino resin silver powder paint disclosed by the invention has the beneficial effects of relatively good adhesion force and covering power, and a paint film has good comprehensive performance.

Description

technical field [0001] The invention relates to a water-based acrylic amino resin silver powder paint and a preparation method thereof, belonging to the field of chemical coatings. Background technique [0002] Silver powder paint is a liquid mixed with silver powder (aluminum powder, etc.) and thinner. It is mostly used for painting the surface of plumbing pipes in old buildings. It is also suitable for heating equipment, vehicles, oil tanks, iron towers, metal pipes, anti-corrosion of metal surfaces and silver decoration of various objects. [0003] Silver powder paint is divided into non-leafing flash silver powder paint and silicone high temperature resistant silver powder paint. Non-leafing glitter silver powder paint is to first soak non-leafing glitter silver paste or pearl powder with appropriate fineness in xylene and other solvents, then slowly add it to the stirred paint, stir at low speed for more than ten minutes, and adjust the appropriate viscosity. Prepared...
