Problems solved by technology

[0002] The luminescent coatings seen in the market are mostly based on solvent-based coatings, which often need to specify strict application ranges and dosages, so that their application areas are limited. No emissivity and better luminous brightness, but they are all solvent-based, and will volatilize harmful organic solvents when coating and forming a film, and the multifunctional luminous coating described in CN1152593A only describes the imitation porcelain tempered coating Or the blending paint has limited use as a film-forming substance, and its composition cannot solve the problem of precipitation of photoluminescent materials due to its large specific gravity

Abstract

A water-based luminescent paint is composed of high molecular polymer emulsion, photoluminescence material, auxiliary agent and water. It is a non-radioactive, non-toxic, non-polluting, environmentally friendly water-based luminescent paint with high-brightness luminous function. The water-based luminescent paint of the present invention has a simple manufacturing process and stable performance, and can be widely used in indoor and outdoor decoration, signage, Emergency instructions in public places.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based luminous paint. Background technique [0002] The luminescent coatings seen in the market are mostly based on solvent-based coatings, which often need to specify strict application ranges and dosages, so that their application areas are limited. No emissivity and better luminous brightness, but they are all solvent-based, and will volatilize harmful organic solvents when coating and forming a film, and the multifunctional luminous coating described in CN1152593A only describes the imitation porcelain tempered coating Or the blending paint has limited application as a film former, and its composition cannot solve the problem of precipitation of photoluminescent materials due to its large specific gravity.
