Problems solved by technology

[0003] Due to the requirements of environmental protection and the concept of green, most of the current photosensitive coatings are water-based systems, and the components such as resin and photosensitive materials need to be dispersed in water. After the dispersion system is dried, the photosensitive materials are easy to agglomerate, which affects the photochromic performance
At the same time, the reversibility of light-sensitive coatings is often inefficient, and the lack of sufficient oxidation leads to low reversibility efficiency. Therefore, it is necessary to improve the reversible discoloration performance of light-sensitive coatings

Abstract

The photosensitive coating comprises 25%-40% of a polyurethane acrylate prepolymer, 5%-10% of a water-absorbing acrylic resin microcapsule, 1%-5% of a reactive dispersant, 10%-20% of photosensitive powder, 1%-10% of a photoinitiator and the balance of water, the dispersing agent is a reactive dispersing agent, and the reactive dispersing agent is acrylamide sulfonate; the water-absorbing acrylic resin microcapsule has a core-shell structure, the shell is polymer resin, and the core is water-absorbing acrylic resin.

Description

technical field [0001] The invention relates to a light-sensitive paint and a preparation method thereof. Background technique [0002] Light-sensitive paint generally means that the paint does not change color or fall off under the illumination of fluorescent lamp or strong light at room temperature, and can maintain certain physical and mechanical properties, showing another color after receiving sunlight. This type of coating can be used in the field of cosmetics to give special properties to packaging materials. When used in some special products, it can attract the attention of the public, thereby increasing the popularity of the products. At the same time, by adjusting the coating formulation, the photosensitive coating can have many good properties, such as weather resistance, so that the product can be used in a wider range of natural areas. [0003] Due to the requirements of environmental protection and the concept of green, most of the current photosensitive coat...
