Embodiment 1

[0024] A kind of environment-friendly light-diffusion paint, is made up of following components by weight: 60 parts of water-based acrylic resin (ECO-36, Dow), 3 parts of coating additives, 2 parts of amino resin microspheres (BMV-2, proficient, particle size 2μm), 40 parts of water.

[0025] The coating additive is composed of the following raw materials in parts by weight: 0.5 parts of defoamer (BYK-024), 1 part of leveling agent (BYK-354), and 1.5 parts of anti-yellowing agent (TDS-103).

[0026] The preparation method of the environment-friendly light-diffusing paint is to stir the water-based acrylic resin, paint additives, amino resin microspheres and water evenly to obtain the environment-friendly water-based light-diffusing paint. The light transmittance test results of the light-diffusing coating prepared in this embodiment are shown in Table 1.

Embodiment 2

[0028] A kind of environment-friendly light-diffusion paint, is made up of following components by weight: 30 parts of water-based polyurethane resin (PU-3461, three liters), 3.5 parts of coating additives, 2 parts of amino resin microspheres (BMV-2 proficient, Particle size 2μm), 30 parts of water.

[0029] The coating additive is composed of the following raw materials in parts by weight: 0.5 part of defoamer (BYK-057), 1 part of leveling agent (BYK-332), and 2 parts of anti-yellowing agent (TDS-103).

[0030] The preparation method of the environment-friendly light-diffusing coating is to stir the water-based polyurethane resin, coating additives, amino resin microspheres and water evenly to obtain the environment-friendly water-based light-diffusing coating. The light transmittance test results of the light-diffusing coating prepared in this embodiment are shown in Table 1.

Embodiment 3

[0032] A kind of environment-friendly light-diffusion paint, is made up of following components by weight: 40 parts of water-based polyester resin (WA-60, Yinlong), 3.5 parts of coating additives, 2 parts of amino resin microspheres (BMV-2 proficient, particle size 2μm), 40 parts of water.

[0033] The coating additive is composed of the following raw materials in parts by weight: 1 part of defoamer (BYK-057), 0.5 part of leveling agent (BYK-354), and 1.5 parts of anti-yellowing agent (TDS-103).

[0034] The preparation method of the environment-friendly light-diffusing coating is to stir the water-based polyester resin, coating additives, amino resin microspheres and water evenly to obtain the environment-friendly water-based light-diffusing coating. The light transmittance test results of the light-diffusing coating prepared in this embodiment are shown in Table 1.

Abstract

The invention belongs to the technical field of environment-friendly paint, and discloses environment-friendly light diffusion paint and a preparation method thereof. The environment-friendly light diffusion paint is prepared from the following components in parts by weight: 20-60 parts of water-based resin, 0.3-10 parts of paint auxiliaries, 0.2-5 parts of a hydrophilic light diffuser and 20-40 parts of water. The method comprises the steps of mixing the water-based resin, the paint auxiliaries, the hydrophilic light diffuser and the water, and uniformly stirring, thereby obtaining the environment-friendly light diffusion paint. The light diffusion paint is high in light transmittance, so that light of a light source is soft, and therefore, the environment-friendly light diffusion paint is green and environmentally-friendly.

Description

technical field [0001] The invention belongs to the technical field of environmental protection coatings, and relates to an environmental protection light diffusion coating and a preparation method thereof. Background technique [0002] Light diffusion materials can convert point light sources into surface light sources, that is, they can convert dazzling light into soft and uniform light. Due to the above effects, light diffusion materials have played an important role in LED lighting, liquid crystal display and other fields. Light-diffusing materials can be divided into light-diffusing plates and light-diffusing coatings. Most of the light-diffusing coatings currently on the market are solvent-based coatings, because they contain a large amount of toxic organic solvents such as acetone, toluene, and xylene. The volatilization of solvents is harmful to the environment and personnel. great harm. Therefore, the development of water-based light-diffusing coatings is both an e...
