Abstract

The invention relates to a luminescent plate. The luminescent plate comprises a luminescent surface layer and a base material layer, the luminescent surface layer and the base material layer are obtained by solidifying corresponding weight parts of raw materials and compounded to prepare the luminescent plate which has moderate strength and toughness, the luminescent plate can be cut into luminescent products of any size and shape, the luminescent brightness of the luminescent plate obtained by compounding the luminescent surface layer and the base material layer is stable, and the luminescentduration is prolonged; the weather resistance, aging resistance and the like of the luminescent plate are further improved, and the situation does not easily occur that since the luminescent plate turns yellow when being used outdoors, the impression is influenced. According to the composition of the raw materials of the luminescent surface layer and the base material layer, a corresponding preparation method is established, all components are even and uniform, the solidified luminescent surface layer and the solidified base material layer are tightly combined, and the performance is stable.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a luminescent plate and a preparation method thereof. Background technique [0002] Luminescent board is a plate product made of photoluminescent materials and resins. It can be used for display signs and signs of ships, vehicles, subways, passages, fire protection, etc., and can be made into various signs and signs by screen printing. It is also used for decoration and decoration of ceilings, wall enclosures, baseboards, etc. in the living room. It can absorb all kinds of visible light to realize the light emitting function, especially has a strong absorption ability for short-wave visible light below 450nm, and can be recycled for many times. The luminescent panel shows its own appearance color in the bright place, and emits light of different colors and brightness in the dark place, showing good low-level emergency lighting, indicating signs and decoration and b...
