Abstract

The invention relates to functional building coating technologies and aims to provide a long-lasting phosphorescent waterborne coating and a preparation method thereof. The coating is prepared by mixing the following raw materials in parts by weight: 30-50 parts of synthetic resin emulsion, 15-30 parts of hydrophobic modified luminescent powder, 12-30 parts of pigments and fillers, 6.5-8 parts of an assistant and 20-40 parts of de-ionized water. The luminescent powder is subjected to hydrophobic modification to obtain the hydrophobic modified luminescent powder which is stable for a long term (more than 6 months) in a waterborne environment and emits light for 12 hours. The hydrophobic modified luminescent powder is introduced into the coating, so that a film-forming material has the functions of being stable for a long term (more than 6 months) in the waterborne coating and emitting light for 12 hours. At the same time, the preparation method is simple, convenient and favorable for reducing the industrialized production cost. According to the preparation method, the raw materials are ground, stirred and dispersed to prepare the coating; the preparation process is simple, easy to implement, simple and convenient to operate and favorable for large-scale industrialized production, and reduces the industrialized production cost.

Description

technical field [0001] The invention belongs to the technical field of functional architectural coatings, in particular to a long afterglow luminescent water-based coating and a preparation method thereof. Background technique [0002] As an energy storage luminescent material, long afterglow luminescent paint has the advantage of long luminescence time, and its nighttime indicating function is applied in tunnels, signboards, indicator marks and other occasions. However, the luminescent material of the long-lasting luminescent paint is usually an easily hydrolyzed inorganic salt, which usually appears in the form of a solvent-based paint, which pollutes the environment and is not suitable for large-scale use in the construction field. [0003] The Chinese invention patent application with the publication number CN01110277.2 discloses a kind of energy storage luminescent coating, which includes 35-40 parts by weight of modified hydrocarbon volume, 25-35 parts by weight of pol...
