Abstract

The invention discloses waterborne paint and a preparation method thereof, and relates to the technical field of paint. According to the technical key points, the waterborne paint is prepared from thefollowing components in parts by weight: 100-120 parts of waterborne polyurethane dispersoid, 30-50 parts of acrylic ester, 6-8 parts of dipropylene glycol methyl ether, 5-25 parts of boiled wood oil, 3-5 parts of bis(2-hydroxyethyl)-methyl-tetradecylazanium,bromide, 10-15 parts of nano-silver sol, 2-6 parts of a coloring agent, 1-3 parts of a dispersing agent, 1-3 parts of an antioxidant and 40-50 parts of deionized water. The waterborne paint prepared through the formula has the moth proofing and antibacterial advantages.

Description

technical field [0001] The invention relates to the technical field of paint, more specifically, it relates to a water-based paint and a preparation method thereof. Background technique [0002] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It does not contain benzene, toluene, xylene, formaldehyde, and free TDI toxic metals. It is non-toxic and non-irritating. It is harmless to the human body and does not pollute the environment. , crystal clear, good flexibility and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, fast drying and convenient use. Can be used on: wood, metal, plastic, glass, building surfaces and other materials. [0003] A Chinese invention patent with the publication number CN107828296A discloses a furniture water-based paint whose main components include absolute alcohol, limonene, polyvinyl butyral, glycerol, ethyl acetate, polyethylene glycol, acryli...
