Problems solved by technology

However, after testing, the glow intensity of this luminescent powder is very low under the excitation of external energy, and the recognizable afterglow time is only 30-60 minutes. 1-2 years, the practical value is not high

Abstract

A light-collecting luminescent pigment and luminescent fiber thereof are disclosed. The pigment consists of light-collecting powder with strontium aluminate as substrate 30-45wt%, refractive reflecting powder 10-15wt% and carrier 40-60wt%. It has excellent wetting ability and adhesion. It can be used for luminescent fiber and other luminescent products.

Description

technical field [0001] The present invention relates to a light-storing (night) luminescent coating, in particular to a luminescent coating that absorbs ultraviolet light energy and stores energy during the day, emits light at night or in the dark, and can reflect light at the same time. Very good wetting is achieved. The invention also relates to a luminescent fiber object coated with the paint and a corresponding luminescent article. Background technique [0002] The so-called luminous coatings, the types that have been recorded at present are: reflective coatings, that is, the coatings contain components that can reflect light substances, and when there is light, they can reflect and emit light. This kind of paint; self-illuminating paint, is to add phosphor to the paint to produce a luminous effect; light-storing luminous paint, the paint is added with light-storing powder, which can store light continuously when there is light, and automatically when the light is dark ...
