Problems solved by technology

[0003] Aiming at the problems of conventional solvent-based filling and coloring paints, such as large odor, high VOC emission, skin irritation, low construction efficiency, and poor paint film adhesion, the present invention aims to provide an environmentally friendly UV hand-rubbing filling and coloring paint, which uses low-viscosity UV resin, matched with special UV monomer, adding appropriate amount of fillers with high smoothness and photoinitiators of different wavelengths, to achieve good construction effect and non-irritating effect on human skin, to achieve real environmental protection, and The adhesion between the substrate and the upper paint film is good. After the color is wiped, it can enter the next process, and the construction efficiency is significantly improved.

Embodiment 1

[0020] The functional monomer is 15 kg of polyethylene glycol 400 diacrylate (PEG400DA), 13 kg of aliphatic urethane acrylic resin, 30 kg of polyether modified polyester acrylic resin, and the photoinitiator is trimethylbenzoyl- 0.5 kg of diphenylphosphine oxide, 0.1 kg of defoamer (TEGO920), 0.5 kg of wetting and dispersing agent, 15 kg of talcum powder, 1 kg of wax powder, 2 kg of fumed silica, mix and stir, after fully dispersed, add light Initiator 2-hydroxy-2-methyl-1-phenyl-1-propanone (1173) 5 kg, stir until fully dispersed and uniform without lumps. The experimental results of this example are: the viscosity of the product is basically moderate, the hardness of the paint film is moderate, the deep curing effect is achieved, and the wiping property is good.

Embodiment 2

[0022] Get 25 kg of functional monomer glycerol methoxy monoacrylate (TPGMEMA), 28 kg of aliphatic urethane acrylic resin, 32 kg of polyether modified polyester acrylic resin, photoinitiator phenyl bis(2,4 , 0.5 kg of 6-trimethylbenzoyl) phosphine oxide (819), 0.1 kg of defoamer, 1 kg of dispersant, 15 kg of talcum powder, 0.5 kg of wax powder, 1 kg of fumed silica, mixed and stirred, fully After dispersion, add 7 kg of photoinitiator phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, stir well and disperse evenly without lumps. The experimental results of this example are: the viscosity of the product is basically moderate, the softness and hardness of the paint film are moderate, the deep layer curing achieves the effect, and the wiping property is good.

Embodiment 3

[0024] Take 15 kg of functional monomer polyethylene glycol 400 diacrylate (PEG400DA), 5 kg of glycerol methoxy monoacrylate (TPGMEMA), 20 kg of aliphatic urethane acrylic resin, polyether modified polyester acrylic acid 25 kg of resin, 0.5 kg of phenyl bis(2,4,6-trimethylbenzoyl) phosphine oxide (819), 0.1 kg of defoamer, 1 kg of dispersant, 15 kg of KB-121 talcum powder, wax powder 0.5 kg, 1 kg of fumed silica, mixed and stirred, after fully dispersed, add 5 kg of photoinitiator 2-hydroxyl-2-methyl-1-phenyl-1-acetone (1173), stir fully and disperse evenly without hard lumps Can. The experimental results of this example are: the viscosity of the product is basically moderate, the hardness of the paint film is moderate, the deep curing effect is achieved, and the wiping property is good.

Abstract

The invention provides an environment-friendly type UV hand-brush filling and coloring coating, which is composed of the following ingredients (by weight0: 15-25 parts of a functional monomer, 13-30 parts of aliphatic polyurethane acrylic resin, 25-32 parts of polyether modified polyester acrylic resin, 15-25 parts of pigments and fillers, 0.5-5 parts of a wetting dispersant, 0.1-1 part of an antifoaming agent, and 4-8 parts of a photoinitiator, wherein the functional monomer is one of polyethylene glycol 400 diacrylate and glycerol methoxyl monoacrylate or a mixture thereof; and the photoinitiator is 2-hydroxy-2-methyl-1-phenyl-1-acetone matched with 2,4,6-trimethylbenzoyl-diphenylphosphine oxide or phenyl bis(2,4,6-trimethylbenzoyl)phosphine oxide. By using low-viscosity UV resin, matching special UV monomer and adding proper amounts of high-slipperiness fillers and the photoinitiator with different wavelengths, a good construction effect and non-irritating effect on human skin are achieved. The coating of the invention has good adhesion to a base material and an upper paint film. After color brushing, the next working procedure can be followed. The construction efficiency is remarkably enhanced.

Description

technical field [0001] The invention belongs to the technical field of UV curable coatings, and in particular relates to an environment-friendly UV hand-wiping filling coloring coating and a preparation method thereof. Background technique [0002] If the furniture industry wants to make a painting effect with transparent color, clear layers and strong three-dimensional effect, it depends on the first-degree coloring of the material, and the paint used is filled and colored paint, commonly known as filler. The filling and coloring coatings used in the industry today are mainly solvent-based products. On the one hand, solvent-based products have a strong odor and high VOC content, which is quite harmful to human health and seriously pollutes the atmosphere. On the other hand, the construction efficiency is extremely low , After the color wiping is completed, it must be placed in an environment of 15-25°C for 12 hours before entering the next process. In winter, due to the low...
