Embodiment 1
[0054] Embodiment 1: A kind of photosensitive coating, the component that comprises and its corresponding parts by weight are shown in Table 1, and adopt following steps to prepare and obtain:
[0055] S1, weigh 15 parts of deionized water, slowly add the corresponding parts by weight of polyacrylic acid sodium salt, fatty alcohol polyoxyethylene ethers, 0.35 parts of non-ionic modified silicone defoamer at a stirring speed of 400-800rpm, Mix for 3-10min to form the first mixture;
[0056] S2, slowly add rutile titanium dioxide R-996, calcined kaolin Ultrex96, and heavy calcium carbonate to the first mixture obtained in S1, gradually increase the stirring speed in the range of 800-1250rpm, and mix for 20-25min to form a second mixture;
[0057] S3, slowly add the remaining deionized water and hydroxyethyl cellulose colloid to the second mixture obtained in S2, the stirring speed is 1000-1250rpm, and mix for 10-15min to obtain the third mixture;
[0058] S4, adjust and maintai...
Embodiment 2-5
[0063] Embodiment 2-5: A photosensitive coating, the difference from Embodiment 1 is that the components and their corresponding parts by weight are shown in Table 1.

Abstract
The invention discloses light-sensitive coating and a preparation process thereof. The light-sensitive coating comprises deionized water, sodium polyacrylate, fatty alcohol polyoxyethylene ether, a non-ionic modified organic silicon defoamer, an organic silicon-based pH regulator BS168, rutile type titanium dioxide R-996, calcined kaolin Ultrex96, heavy calcium carbonate, hydroxyethyl cellulose colloid, bactericide, self-crosslinked acrylic emulsion, light-sensitive color-changing toner, dioctyl phthalate, ethanol and an ultraviolet absorbent, wherein the self-crosslinked acrylic emulsion is E-3030 self-crosslinked acrylic emulsion or SF-500 self-crosslinked acrylic emulsion; and the ultraviolet absorbent comprises at least two of phenyl salicylate, 2-hydroxyl-4-octyloxybenzophenone and hexamethylphosphoramide. The light-sensitive coating and the preparation process thereof have the advantages that the light-sensitive coating is harmless for a human body, can change colors, and is not liable to serous breakage when being subjected to an action force.
Description
technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a photosensitive coating and a preparation process thereof. Background technique [0002] For home decoration, traditional solvent-based wall paint is usually used. The organic solvent volatiles produced by it, such as formaldehyde, pollute the indoor environment, damage the human respiratory system, hematopoietic function, and immune system, and even cause Certain genetic diseases seriously endanger human health. While consumers pay more and more attention to their health, they also pay more attention to the performance of wall paint used in interior decoration. Therefore, consumers have higher and higher requirements and standards for the selection of wall paint. [0003] The wall paint in the prior art is always white no matter day or night, and the color is relatively single, which is difficult to satisfy the increasingly changeable personalities of differen...
