Abstract

The present invention relates to a energy-storing water-borne luminescent paint. Said invention adopts strontium aluminate activated by bivalent europium as luminescent powder, adopts the acrylic resin process or polyethylene wax process to make coating treatment of luminescent powder surface, so that it can raise the hydrolysis stability of luminescent powder. Said invention uses water epoxy resin emulsion as base material, and matches it with filling material, adjuvant and solidifying agent so as to obtain the invented luminescent paint. After the surface of body is coated with said paint, and dried, a luminescent coating layer is formed, after which is irradiated by UV ray, sun light and fluorescent lamp, the light energy can be stored by it, after the light source is removed.

Description

technical field [0001] The invention relates to the improvement of luminous paint technology, in particular to an environment-friendly water-based epoxy energy-storing luminous paint, which belongs to the technical field of chemical compositions. Background technique [0002] In the past, most of the luminescent coatings used copper-activated zinc sulfide (ZnS: Cu) luminescent powder as the luminescent material. The afterglow of this luminescent material can only reach 1-2 hours, and it is easy to deteriorate and fail after being irradiated by ultraviolet rays or contacting oxygen. Deuterium and Pm are also added to prolong the afterglow 147 Such radioactive elements are harmful to the human body, so they are gradually eliminated by the market. In recent years, it has been discovered that europium-activated strontium aluminate (SrAl 2 o 4 : Eu +2 ) type luminescent material, the afterglow time of the luminescent material is longer, up to more than 12 hours. The luminesc...
