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
The present invention relates to a kind of preparation method of coating, relate in particular to a kind of preparation method of UV curing luminous paint.
Background technology
Along with the development of modern science and technology and the enhancing day by day of people's environmental consciousness, more and more urgent to the demand that can produce tremendous economic and social benefit, environmental protection composite functional material attractive in appearance.The rare earth light-storing and emitting material as a kind of environmental protection, stable, " green " luminescent material has caused people's extensive concern efficiently.The luminous paint of ultraviolet light polymerization has fabulous light-accumulated luminous effect, life-span is long, can under outdoor sunlight, be exposed to the sun, round-the-clock use, nontoxic, safe and reliable, can be used for that round-the-clock outdoor various indicatrixs, billboard, Emergency Light, building decoration are decorateed and the fields such as direction board of motorway.
Luminous indication mechanism in the buildings is mainly the electroluminescence type Pointing sign board.Yet, because the electroluminescent label must rely on power supply, and must be ability works better under the situation that all components and parts do not damage, in case power failure, outage or components and parts damaged condition occur, promptly can not bring into play its sign, indicative function.And the long afterglow photoluminescence label is the energy of absorption sunlight and light and stores, and sends light in the dark again, does not need power supply, there is not damage of components and out of use problem, also do not need routine maintenance, the reliability height is optimal emergent Warning Mark.Long after glow luminous material is a class advanced luminescent material that grows up early 1990s, the luminosity height, time of persistence is long, "dead" pollution, and the kind of luminescent material is constantly increasing, and the scope of emission wavelength has also almost covered whole visible lights, this makes long-persistence luminous label not only obtain to use widely aspect the emergent indication, and also the application for other sign, sign provides wide prospect.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of UV curing luminous paint, table and rare earth overlength afterglow luminescent material (SrAl after the modification
