Embodiment 1

[0022] Embodiment 1: A kind of UV-curable water-based coating whose raw material components are calculated by weight: 65 parts of water-based polyurethane acrylate, 15 parts of 25wt% tea polyphenol solution, 15 parts of ethylene urea ethyl acrylate, chitosan 5 parts, 5 parts of titanium dioxide photocatalystase, 2 parts of ethyl 2,4,6-trimethylbenzoylphenyl phosphonate, 0.3 parts of alkyl modified organosiloxane leveling agent, 7 parts of cosolvent, Fumed silica anti-settling agent 0.3 parts, defoamer 1 part, water 140 parts. The prepared coating can effectively absorb and decompose harmful substances such as benzene, formaldehyde, toluene, xylene, etc., reduce the content of indoor harmful substances, and is safe and environmentally friendly.

Embodiment 2

[0023] Example 2: A UV-curable water-based coating whose raw material components are calculated by weight: 75 parts of water-based polyurethane acrylate, 20 parts of 25wt% tea polyphenol solution, 20 parts of ethylene urea ethyl acrylate, chitosan 8 parts, 8 parts of titanium dioxide photocatalystase, 4 parts of 1-hydroxycyclohexyl phenyl ketone, 0.6 parts of polyether modified polydimethylsiloxane leveling agent, 8 parts of cosolvent, N of modified polyurea 0.5 parts of monomethylpyrrolidone anti-settling agent, 1.5 parts of defoamer, and 250 parts of water. The prepared coating can effectively absorb and decompose harmful substances such as benzene, formaldehyde, toluene, xylene, etc., reduce the content of indoor harmful substances, and is safe and environmentally friendly.

Embodiment 3

[0024] Embodiment 3: The raw material components of a kind of ultraviolet curing water-based paint are calculated by weight: 70 parts of water-based polyurethane acrylate, 18 parts of 25wt% tea polyphenol solution, 18 parts of ethylene urea ethyl acrylate, chitosan 5 parts, 5 parts of titanium dioxide photocatalyse, 2 parts of ethyl 2,4,6-trimethylbenzoylphenyl phosphonate, 2 parts of 2-hydroxy-2-methyl-1-phenyl-1-propanone , 0.5 parts of acrylate leveling agent, 10 parts of co-solvent, 0.3 parts of fumed silica anti-settling agent, 1.2 parts of defoamer, 220 parts of water. The prepared coating can effectively absorb and decompose harmful substances such as benzene, formaldehyde, toluene, xylene, etc., reduce the content of indoor harmful substances, and is safe and environmentally friendly.

Abstract

The invention relates to the technical field of coatings, in particular to a UV-curable waterborne coating. The UV-curable waterborne coating is prepared from the following raw materials in parts by weight: 65-75 parts of waterborne polyurethane acrylate, 15-25 parts of 25wt% tea polyphenol solution, 15-20 parts of ethylidene urea ethyl acrylate, 5-10 parts of chitosan, 5-10 parts of titanium dioxide photocatalysis, 2-4 parts of photoinitiator, 0.3-0.6 parts of flatting agent, 5-10 parts of cosolvent, 0.2-0.5 parts of anti-settling agent, 1-1.5 parts of antifoaming agent and 140-250 parts of water. The prepared coating can effectively absorb and decompose harmful substances such as benzene, formaldehyde, methylbenzene, xylene and the like, reduce the content of the harmful substances indoors, and is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an ultraviolet curing water-based coating. Background technique [0002] Solvent-based coatings, after long-term development, have high decorative properties, durable protection, and multi-functional innovations; but organic solvents volatilize, causing environmental pollution, and most of them are toxic to humans, animals, organisms, and even plants. With the enhancement of people's awareness of environmental protection, the paint industry has also begun to develop along the direction of sustainability. As a result, we are seeing more and more solvent-free coatings or coating systems using low levels of VOCs. The development of safe and low-VOC water-based coatings is imperative. Compared with traditional oil-based UV coatings, water-based UV coatings have the following advantages: [0003] 1. Reduce the curing shrinkage caused by the use of a large amount of reactive diluents, and can...
