Embodiment 1

[0022] Embodiment 1: A kind of formaldehyde-removing ultraviolet curable water-based coating whose raw material components are calculated by weight: 65 parts of water-based polyurethane acrylate, 15 parts of bamboo charcoal fiber, 15 parts of graphene, 5 parts of chitosan, titanium dioxide photocatalyst 5 parts, 2 parts of ethyl 2,4,6-trimethylbenzoylphenyl phosphonate, 0.3 parts of alkyl modified organosiloxane leveling agent, 7 parts of co-solvent, fumed silica anti-settling agent 0.3 parts, 1 part of defoamer, 140 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 2

[0023] Embodiment 2: A kind of formaldehyde-removing ultraviolet curing water-based coating whose raw material components are calculated by weight: 75 parts of water-based polyurethane acrylate, 20 parts of bamboo charcoal fiber, 20 parts of graphene, 8 parts of chitosan, titanium dioxide photocatalyst 8 parts, 4 parts of 1-hydroxycyclohexyl phenyl ketone, 0.6 parts of polyether modified polydimethylsiloxane leveling agent, 8 parts of co-solvent, N-methylpyrrolidone anti-settling agent of modified polyurea 0.5 parts, 1.5 parts of defoamer, 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] Implementation 3: The raw material components of a formaldehyde-removing UV-curable water-based coating are: 70 parts of water-based polyurethane acrylate, 18 parts of bamboo charcoal fiber, 18 parts of graphene, 5 parts of chitosan, and 5 parts of titanium dioxide photocatalystase 2 parts, 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, and 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 field of paint, particularly to a formaldehyde removing ultraviolet curing water-based paint which is prepared from the following components in parts by weight: 65-75 parts of waterborne polyurethane acrylate, 15-25 parts of bamboo carbon fiber, 15-20 parts of grapheme, 5-10 parts of chitosan, 5-10 parts of titanium dioxide photocatalyst, 2-4 parts of a photoinitiator, 0.3-0.6 part of a flatting agent, 5-10 parts of a cosolvent, 0.2-0.5 part of an anti-settling agent, 1-1.5 parts of a defoamer and 140-250 parts of water. The prepared paint can effectively absorb and decompose hazardous substances of benzene, formaldehyde, methylbenzene, xylene and the like, reduces the content of the indoor hazardous substances, and is safe and environment-friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a formaldehyde-removing UV-cured 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 diluen...
