preparation example Construction

[0036] Further, the present invention also provides a preparation method of water-based light-cured floor coating, characterized in that, as figure 1 shown, including steps:

[0037] S100. Mix ethoxylated pentaerythritol tetraacrylate, active amine resin, photoinitiator, wear-resistant powder, dispersant, substrate wetting agent, leveling agent and defoamer, and stir at the first speed until the solid is completely dissolved to obtain the first mixture;

[0038] S200. Mix the hexafunctional water-based polyurethane acrylic resin and the difunctional water-based polyurethane acrylic resin, stir at the second rotational speed, and gradually add the first mixture, matting powder and dipropylene glycol methyl ether dropwise during the stirring process, to obtain the second mixture;

[0039] S300. Filter the second mixture with a 200-mesh filter to obtain the water-based photocurable floor coating.

[0040]In this embodiment, by using a 200-mesh filter to filter the second mixtu...

Abstract

The invention discloses waterborne photocuring floor coating and a preparation method thereof. The coating is prepared from, in percentage by weight: 55-65% of hexa-functional group waterborne polyurethane acrylic resin, 5-10% of di-functional group waterborne polyurethane acrylic resin, 5-15% of pentaerythritol tetraacrylate ethyl oxide, 1-5% of active amine resin, 3-12% of a photoinitiator, 2-7%of extinction powder, 1-5% of wearproof powder, 0.2-1% of a dispersing agent, 0.5-2% of a base material wetting agent, 0.1-0.5% of a flatting agent, 0.01-0.1% of a defoaming agent and 5-15% of dipropylene glycol methyl ether. The coating can be rapidly solidified to form a film through ultraviolet irradiation after being subjected to roller coating, the speed is high, the efficiency is high, thecoating has the high performance of coin scratching resistance, solvent resistance, water resistance, iodine resistance and high wear resistance after being the film independently, and the features oflog can be presented.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based light-curing floor coating and a preparation method thereof. Background technique [0002] UV light-curing coating is a new type of coating with low environmental pollution, energy saving and high efficiency. Generally, the reactive diluents used in UV coatings are monomers or solvents, and the odor or irritation of the coatings is relatively high. Compared with traditional organic UV coatings, the diluent of water-based UV coatings is mainly water, which can achieve extremely low VOC (volatile organic compounds), reduce the odor and irritation of coatings, and achieve truly harmless and environmentally friendly. [0003] In order to make the floor have better scratch resistance, it is generally necessary to apply multi-coat traditional UV light-curing coatings on the floor. For example, first apply putty, then coat primer and topcoat, etc., through multiple layers Layer c...
