Embodiment approach

[0026] (1) The urethane acrylate is composed of self-emulsifying urethane acrylate and external emulsifying water-based urethane acrylate, and the mass ratio of self-emulsifying urethane acrylate to externally emulsifying water-based urethane acrylate is 1:0.8~1 :1.2. In practical application, the self-emulsifying polyurethane acrylate can adopt RPCURE T-101 produced by Jiangsu Ruipu Resin Technology Co., Ltd., and the externally emulsifying water-based polyurethane acrylate can adopt RPCURE T-101 produced by Jiangsu Ruipu Resin Technology Co. 9061.

[0027] (2) The acrylate is a self-emulsifying acrylate. In practical applications, the self-emulsifying acrylate can be RPCURE 9092 produced by Jiangsu Ruipu Resin Technology Co., Ltd.

[0028] (3) The silver powder is silica-coated silver powder.

[0029] (4) The silver powder dispersant is a high molecular weight block copolymer with pigment affinity groups.

[0030] (5) The additives include wetting additives, defoaming ad...

Embodiment 1

[0037]An environment-friendly UV photocurable water-based silver powder paint, which is composed of the following components in mass fractions: self-emulsifying polyurethane acrylate 25-30%, external emulsifying water-based polyurethane acrylate 25-30%, self-emulsifying acrylate 1 ~5%, photoinitiator 2.5~3.5%, silica-coated silver powder 4~5%, silver powder dispersant 0.2~0.5%, wetting aid 0.5~1%, defoaming aid 0.1~0.5%, 1-3% of anti-sedimentation aid, 0.5-1% of thickening aid, and deionized water as the balance.

[0038] Specifically, the preparation method of the environment-friendly UV light-curable water-based silver powder paint may include: according to the component distribution ratio of the above-mentioned environment-friendly UV light-curable water-based silver powder paint, the emulsified polyurethane acrylate, the external emulsified water-based polyurethane acrylate, and the self- Emulsifying acrylate, photoinitiator, silica-coated silver powder, silver powder disp...

Abstract

The invention discloses an environment-friendly UV light-cured water-based silver powder paint, and a preparation method and a use method thereof. The environment-friendly UV photocuring water-based silver powder paint comprises the following components in percentage by mass: 50 to 60% of urethane acrylate, 1 to 5% of acrylate, 2.5 to 3.5% of a photoinitiator, 4 to 5% of silver powder, 0.2 to 0.5%of a silver powder dispersing agent and 1 to 6% of an auxiliary agent, with the balance being deionized water. According to the invention, surface drying can be completed without UV curing, excellentphysical and chemical properties are achieved after UV curing, use of an organic solvent is avoided, and the problem that the organic solvent volatilizes and pollutes the environment is solved.

Description

technical field [0001] The invention relates to the field of water-based UV (Ultravioletray, ultraviolet) light-cured coatings, in particular to an environment-friendly UV light-cured water-based silver powder paint and a preparation method and use method thereof. Background technique [0002] With the development of social economy and the improvement of environmental protection awareness, people have put forward higher and higher requirements for the development of UV single-coated silver powder paint. Traditional UV single-coat silver powder paint has problems such as organic solvent volatilization and pollution of the environment, so the application of traditional UV single-coat silver powder paint is subject to more and more restrictions. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an environment-friendly UV light-curing water-based silver powder paint and its preparation method and appl...
