Abstract

The invention relates to a continuous color-changing interior decoration coating comprising the following components in percentage by weight: 82-88.0% of a polyurethane emulsion, 1.0-3.0% of a coordination compound, 3.0-5.0% of EFC-300, 5-7% of a filling material, 0.7-0.9% of TEGO Disper 752, 1.6-2% of a heteropolyacid photosensitizer, 0.08-0.12% of Foamaster A34, 0.08-0.12% of an SN-thickener 641 and 0.1-0.3% of Levelling 620. The continuous color-changing interior decoration coating disclosed by the invention can be changed into different colors under the illumination with different intensities; moreover, various properties and environmental friendliness of the coating are superior to the prior art.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a continuous color-changing interior decoration coating and a preparation method thereof. Background technique [0002] Photochromism refers to the change of the molecular structure of certain compounds under the action of light of a certain wavelength and intensity, resulting in a corresponding change in the color of the light absorption peak, and this change is generally reversible. Color-changing paint is a paint in which the color of the coating changes with environmental conditions. At present, there are many types of color-changing paints on the market. According to different light sources, the coating presents different colors. In daily life, it can relieve people's visual fatigue , brings visual freshness, and is especially widely used in interior decoration coatings, interior furniture surface coatings and other household items. [0003] At present, most of the color-changing pa...
