Abstract

Luminous water paint containing long-lasting phosphorescence material coated with nano titanium dioxide and a preparation method thereof are disclosed, belonging to luminous water paint field and inorganic luminous paint and particularly luminous paint coating treatment technique. The preparation method includes the following steps: firstly, coating the long-lasting phosphorescence material with nano titanium dioxide, then preparing the water paint from the coated long-lasting phosphorescence material, film-forming emulsion resin, filler, addition agent and water. The luminous water paint has good stability to hydrolysis and good adhesive attraction; the paint film is of good water resistance, alkali resistance, weather resistance, high brightness and long after time. The luminous water paint is applicable in door and out of door and applicable to boats and road signs and is particularly suitable for underwater signs and road signs in pluvial regions.

Description

technical field [0001] The invention belongs to the field of luminescent coatings, and relates to inorganic luminescent materials, especially the coating treatment technology of luminescent materials. Background technique [0002] At present, there are two main types of energy storage luminescent materials used in the coating industry, namely zinc sulfide ZnS luminescent materials and rare earth activated alkaline earth metal aluminate luminescent materials i . A typical representative of zinc sulfide-based energy storage luminescent materials is zinc sulfide activated by copper and cobalt, which is light yellow powder. Zinc sulfide-based luminescent materials have always been considered as a long-lasting luminescent material and are used in many fields. However, the afterglow of this material can only last for 1 to 2 hours, and it does not have sufficient brightness in many applications, and it is easy to deteriorate after being exposed to ultraviolet rays or oxygen.
