Embodiment Construction

[0021] Below in conjunction with example the present invention will be further described.

[0022] Various implementation examples and the contents of each component are listed in Table 1. The above example is the formulation of the luminescent layer. Weigh the raw materials according to the formula, add other materials except the luminescent material into the high-speed disperser, disperse evenly at high speed, and then add the luminescent material and disperse evenly at high speed to obtain the luminescent material.

[0023] There are three methods for making luminescent panels. The first is to apply luminescent paint directly on white or light-colored plates such as PVC whiteboards to form a luminescent layer with a thickness of 0.02-5.0mm and a wavelength of 200- 600nm, 5.6-8KW ultraviolet light source irradiation, speed 4.0-10.0m / min can get a uniform luminous panel. The second method is to directly use white or light-colored film as the reflective layer, apply luminesce...

Abstract

An UV curing luminescent panel consists of a luminescent layer and a reflective layer. The luminescent layer with the thickness of 0.02-5.0mm consists of light-cured resin (10-40 percent of resins such as epoxy acrylic resin, polyurethane acrylic resin, polyester acrylic resin and the like), photosensitive diluent (photosensitive diluent is 10-20 percent of resins of ethoxylated acrylic ester, propoxylated neopentyl glycol diacrylate, TMPTA and the like), photoinitiator (2-10 percent of beans development kit BDK and the like), luminescent materials (10-65 percent) and additive (0-5 percent). The UV curing luminescent panel has the advantages of no solvent emission, saving energy due to instant drying of UV curing, high production efficiency due to on-line processing, and being applicable to base materials sensitive to heat; furthermore, the prepared luminescent panel is characterized by high brightness, long luminescent time, excellent acid and alkali resistance and weatherability, good printing performance, non-toxicity, no radiation and stable physicochemical performance.

Description

Technical field: [0001] The invention relates to a composition and a manufacturing method of a light-storage photoluminescent plate. Background technique: [0002] Luminescent board is a board product made of photoluminescent materials and resins. It can be made into a low-profile display light source board, which can be used for display signs and signs of ships, vehicles, subways, passages, fire protection, etc., and It can be made into various signs and signs by screen printing, and it is also suitable for decoration and decoration of ceilings, wall enclosures, baseboards, etc. in the living room. It can realize the function of emitting light by absorbing various visible light, especially has a strong absorption ability for short-wave visible light below 450nm, and can be recycled for many times. The light-emitting board presents its own appearance color in the bright place, and emits light of different colors and brightness in the dark place, showing good low-level emerg...
