Abstract

The invention discloses a fluorescent and transparent thin film. The fluorescent and transparent thin film comprises a surface layer and an inner layer, wherein the inner layer is clung to the surface layer; the surface layer is a high-transparency thin film and the inner layer is a fluorescent thin film; and the light transmittance of the surface layer is more than or equal to 90% and the fluorescent brightness of the inner layer is more than or equal to 150cd / m<2>. According to the invention, the thin film has the characteristics of high light transmittance and high fluorescent brightness. The invention further discloses a preparation method of the fluorescent and transparent thin film. By adopting the preparation method, the fluorescent brightness and the light transmittance of the thin film can be improved.

Description

technical field [0001] The invention relates to the field of plastic films, in particular to a fluorescent transparent film; correspondingly, it also relates to a preparation method of the fluorescent transparent film. Background technique [0002] At present, fluorescent films can be used in LED luminescent materials, night-time marking materials, decorative materials and other fields, and their preparation methods and formulas are also different. And the fluorescent film that existing decoration and night mark are used is to add appropriate fluorescent powder on the basis of existing plastic film formula, makes after adjusting corresponding production process. In order to ensure the fluorescent brightness of the film, many manufacturers realize it by increasing the thickness of the film or increasing the content of phosphor powder, but the above-mentioned technological means directly lead to a great decrease in the light transmittance of the film, which affects the applica...
