Problems solved by technology

These coatings have several shortcomings that cannot be overcome at present: 1. The coatings contain organic solvents, which are harmful to the environment; 2. The effect of the film surface depends on the leveling effect, and the flatness of the film surface cannot be guaranteed; 3. The surface hardness is low. It has anti-damage performance; 4. The surface energy is high, and the stain resistance cannot be guaranteed
At present, UV coatings are mainly used in wood paints, adhesives and other fields. Due to the inability to achieve large-area coatings, their application in interior wall coatings is limited.

Embodiment 1

[0020] Preparation of interior wall paint: Take 400g of epoxy acrylate, 500g of diethylene glycol acrylate, 300g of titanium dioxide, 20g of 2-hydroxy-2-methyl-1-phenylacetone, 3g of BYK358N, 3g of BYK110, 3g of BYK410, Mix evenly under high-speed stirring, grind for 2 hours with a basket sand mill, and store in a sealed and dark place.

[0021] Painting of interior wall paint: use spraying process to evenly coat the paint on the surface of the interior wall, every 1m 2 Cover with a layer of polyester film, and expose the coating to the air for 5 minutes. After the entire wall is painted and covered, a UV light source with a power of 120W / cm is placed and cured for 10 minutes.

Embodiment 2

[0023] Preparation of interior wall paint: Take 300g of polyurethane acrylate, 500g of isobornyl acrylate, 500g of carbon black, 10g of 1-hydroxycyclohexyl phenyl ketone, 2g of BYK358N, 2g of BYK110, and 2g of BYK410, and mix them uniformly under high-speed stirring. Grind with a basket sand mill for 2 hours, and store in a sealed and dark place.

[0024] Painting of interior wall paint: use the spraying process to evenly coat the interior wall paint on the surface of the interior wall, every 0.5m 2 Cover with a layer of polyethylene film, and expose the coating to the air for 8 minutes. After the entire wall is painted and covered, place a UV light source with a power of 150W / cm for 10 minutes to cure.

Embodiment 3

[0026] Preparation of interior wall paint: Take 400g of polyether acrylate, 600g of isobornyl methacrylate, 200g of iron oxide red, 2-methyl-2-(4-morpholinyl)-1-[4-(methylsulfide Base) phenyl] -1-acetone 30g, BYK358N 4g, BYK110 4g, BYK410 2g, mix uniformly under high-speed stirring, grind with a basket sand mill for 2 hours, seal and store away from light.

[0027] Coating of interior wall paint: use spraying process to evenly coat the interior wall surface, every 1m 2 Cover with a layer of polypropylene film, and expose the coating to the air for 10 minutes. After the entire wall is painted and covered, place a UV light source with a power of 90W / cm to cure for 30 minutes.

Abstract

The invention discloses an antifouling and antidamage interior wall coating and a coating method thereof. The interior wall paint is composed of the following components in parts by weight: 30-50 parts of prepolymer, 40-60 parts of acrylic monomer, 20-50 parts of pigment, 1-6 parts of photoinitiator and 0.2-1 part of auxiliary agent. When painting, use spraying or roller coating process to evenly coat the paint on the surface of the inner wall, every 0.5 ~ 1.5m 2 Cover with a layer of film, and the coating should be exposed to the air for no more than 10 minutes, and then put a UV light source with a power of 90-150W / cm to cure for 10-60 minutes. The interior wall coating does not contain organic solvents, is green and environmentally friendly, and has no harm to the environment; after coating, the coating has good anti-damage performance, good stain resistance, good flatness, and beautiful wall surfaces.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antifouling and antidamage interior wall coating and a coating method thereof. Background technique [0002] With the improvement of people's living standards, higher requirements are put forward for the waterproof, anti-fouling and anti-damage performance of building interior wall coatings. At present, interior wall coatings with anti-fouling and anti-damage properties mainly include coatings prepared with acrylic acid, epoxy resin and polyurethane, or their silicon- and fluorine-modified polymers as base materials, and the coating conditions are all room temperature curing conditions. These coatings have several shortcomings that cannot be overcome at present: 1. The coatings contain organic solvents, which are harmful to the environment; 2. The effect of the film surface depends on the leveling effect, and the flatness of the film surface cannot be guaranteed; ...
