Abstract

The invention discloses an energy-storage environment-friendly water-based luminescent coating and a preparation method thereof. The coating includes a primer and a finish paint , the finish paint comprises, by mass, 35-55 parts of a water-based emulsion, 20-40 parts of noctilucent powder, 10-15 parts of a curing agent, 4-6 parts of a diluent, 1-2 parts of a dispersing agent, 0.2-1 part of a defoaming agent, 0.4-1 part of an anti-settling agent and 0.6-1 part of a thickening agent; and the difference between the primer and the finish paint is that noctilucent powder is not added. The water-based luminescent coating is an energy-storage environment-friendly coating, can be directly diluted with water as a diluent in the coating process and used for coating, does not use the diluent needed in the coating process of a solvent-based coating, greatly reduces VOC emission, only contains a very small amount of a cosolvent, basically has no influence on the environment, and is environment-friendly; and meanwhile, the coating has the properties of higher initial luminance, lasting afterglow, water resistance, strong adhesive force, excellent insulating property and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an energy-storage and environment-friendly water-based luminous coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of social economy and the improvement of people's living standards, higher requirements have been put forward for the development of the coating industry. Ordinary exterior wall architectural coatings often have defects such as poor stain resistance and insufficient aging resistance, and have gradually been unable to meet the needs of modern society. High performance, environmental protection and decoration have gradually become the mainstream development trend. [0003] As a kind of functional coating, luminescent paint has the characteristic of emitting bright light in dark places after being irradiated by sunlight or indoor lighting. Therefore, luminous paint can be sprayed and printed on various ...
