High hardness and high wear resistance waterborne wood paint and preparation method thereof

Abstract

The invention discloses a high hardness and high wear resistance waterborne wood paint and a preparation method thereof. The high hardness and high wear resistance waterborne wood paint is composed of the following components by weight: 60-80 parts of a waterborne acrylic aliphatic polyurethane copolymerization emulsion L-3928; 10-30 parts of waterborne polyurethane resin L-2967; 0.1-1 part of a wetting agent TEGO270; 0-5 parts of a nano-alumina slurry VK-L30W; 0-1 part of a defoaming agent BYK028; 1-10 parts of a film-forming assistant dipropylene glycol methyl ether; 0-2 parts of a preservative HTK-30; 1-20 parts of water; 0.1-1 part of a leveling agent EFKA3772; 0.1-1 part of a leveling agent EFKA3034; and 0.1-1 part of a thickener RM-12W. The product provided by the invention has high hardness and good wear resistance, and the hardness can be greatly improved without changing the luster. By adopting the two-component leveling agents, the handfeel and fullness of the product are improved.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a water-based wood paint with high hardness and high wear resistance and a preparation method thereof. Background technique [0002] Since traditional solvent-based coatings are a major cause of environmental pollution, solvent-based coatings use organic solvents as the main dispersion medium. During the production and use of coatings, volatilized organic solvents will not only affect human health, but also act as organic solvents When volatilized into the atmosphere, it will also pollute the atmosphere. Therefore, in order to protect the environment in which we live and our health, the production and use of environmentally friendly coatings has become an urgent problem to be solved in the coatings industry, and the water-based coating is the best way to solve this problem, because water-based coatings use water as the dispersion. The medium greatly reduces the applicatio...

Problems solved by technology

[0003] Among them, the development of water-based wood lacquer is very representative, and it is also a main research direction of paint researchers, but there are still problems and defects in water-based wood lacquer: the hardness and abrasion resistance of water-based wood lacquer are obviously much worse than those of solvent-based, water-based wood lacquer Because the solid content of water-based resins is not as high as that of similar oil-based resins for wood paints, the fullness of the products produced is often worse than that of solvent-based wood paints. Since the volatilization of water requires more energy than the volatilization of solvents, the use environment of water-based paints stricter requirements
