Abstract

The invention relates to a preparation method of an ultraviolet curing luminous coating which is prepared by the following formula according to the weight percentage: 1 percent to 20 percent of rare earth superlong afterglow luminescent material which is carried out the surface modification by vinylsilane coupling agent, 40 percent to 70 percent film-forming substance, 1 percent to 10 percent photoinitiator, 5 percent to 25 percent pigment and filler, 0 percent to 5 percent organic solvent or water, 0.01 percent to 5 percent dispersant, 0.01 percent to 5 percent defoamer and 1 percent to 8 percent other auxiliary agents. The preparation method has the advantages that: 1. the surface modified rare earth superlong afterglow luminescent material has better compatibility and simultaneously improves the luminous intensity of the luminous coating and prolongs the luminescence time; 2. the ultraviolet curing luminous coating not only has the luminous performance as the ordinary luminous coating, but is also characterized by rapid curing, good coating performance, no greatly volatile solvent, and the like; and 3. the preparation method is beneficial to the elimination of the environmental pollution and the saving of the organic solvent.

Description

technical field [0001] The invention relates to a preparation method of a paint, in particular to a preparation method of an ultraviolet light curing luminous paint. Background technique [0002] With the development of modern science and technology and people's increasing awareness of environmental protection, the demand for composite functional materials that can produce huge economic and social benefits and are environmentally friendly and beautiful is becoming more and more urgent. Rare earth light-storing luminescent materials have attracted widespread attention as an environmentally friendly, stable and efficient "green" luminescent material. UV-cured luminous coatings have excellent light-storing and luminescent effects, and have a long lifespan. They can be exposed to the sun outdoors and can be used all-weather. Architectural decoration and highway signs and other fields. [0003] The luminescent indication system in the building is mainly an electroluminescence t...
