Embodiment 1

[0068] The present embodiment 1 water-based photochromic coating is made after LED photocuring by the following components by weight:

[0069]

[0070] The preparation method is as follows:

[0071]Add 15 parts of water-based aliphatic urethane acrylate UCECOAT 7200 (Allnex), 15 parts of UCECOAT 7177 water-based aliphatic urethane acrylate (Allnex), and 1 part of deionized water into a mixing bucket with a condenser. Then, under the condition of uniform stirring, add 5 parts of reactive emulsifier ER-20 into the above emulsion system to make it uniformly dispersed in the solvent, stirring at 800r / min for 0.5 hours. Then, add 0.05 parts of dispersant DISPERBYK-180 to make it evenly dispersed in the system. Then, gradually add 0.2 parts of #19 red photosensitive microcapsule powder (Chongyu Co., Ltd.), increase the stirring speed to 1200r / min, and stir for 0.5 hours. Then, add 30 parts of epoxy monomer EP-4231 (Hengqiao Industry), 0.2 part of free radical photoinitiator IRG...

Abstract

The invention discloses a waterborne photochromic coating as well as nail polish and a decorative material. The waterborne photochromic coating is prepared from the following components in parts by weight: 30 to 90 parts of a waterborne polyurethane acrylate oligomer, 1 to 10 parts of an epoxy group-containing monomer, 0.5 to 5 parts of a reactive emulsifier, 0.5 to 10 parts of a photoinitiator, 0.2 to 30 parts of a waterborne photochromic agent, 0.5 to 5 parts of a waterborne wetting dispersant, 0.05 to 5 parts of a waterborne flatting agent and 1 to 20 parts of deionized water. The waterborne photochromic coating disclosed by the invention has the advantages that the problems of low curing speed and low efficiency of a heat curable photochromic coating, and the problem that a large amount of solvents or volatile monomers are used in a UV (ultraviolet) photochromic coating are solved; the waterborne photochromic coating is suitable for coating various plastic substrates or nail, and has relatively-high industrial production benefits and a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based photochromic coating, nail polish and decorative materials. Background technique [0002] In recent years, with people's increasing emphasis on environmental protection and the gradual strengthening of environmental regulations, the traditional coatings industry has undergone tremendous changes. Because traditional solvent-based coatings contain a large amount of volatile organic compounds, the country has increasingly strict restrictions on the production conditions of solvent-based coatings. In recent years, the development of low-pollution or even non-pollution environment-friendly powder coatings, water-based coatings, light-curing coatings, etc. has become the main direction of coating development. Powder coating is a new type of solvent-free 100% solid powder coating. This type of coating has the characteristics of solvent-free, pollution-free, ...
