Problems solved by technology

However, this kind of light-storing luminescent powder currently only has five varieties of luminescent pigments: yellow-green, red, sky blue, blue, and purple, and the color is relatively dark during the day, and the luster is not enough. When used in advertisements, colored paper, etc. Will affect the normal visual effect

Embodiment 1

[0015] Example 1: A method for making high-brightness color fluorescent and light-storing luminescent powder, which is based on the primary product of red fluorescent powder and light-storing luminescent powder, after dissolving the fluorescent powder to remove residues, preparing a fluorescent solvent→adding light-storing luminescent powder→air-drying→grinding And other steps are processed to obtain the finished product that meets the requirements. The specific production method is to carry out the following steps:

[0016] (1) Dissolving the fluorescent powder and preparing the fluorescent solvent: Add 500 grams of red fluorescent powder in a closed container containing 1,000 ml of thinner water, stir thoroughly for 30 hours, then let it stand for stratification, remove the sediment, and obtain the upper layer Liquid fluorescent solvent;

[0017] (2) Add light-storing luminescent powder: add 400 grams of light-storing luminescent powder to the fluorescent solvent obtained a...

Embodiment 2

[0021] Embodiment 2: A method for making high-brightness color fluorescent light-storing luminescent powder, which is based on the yellow fluorescent powder and the yellow-green light-storing light-storing powder as the primary product, after dissolving the yellow fluorescent powder to remove residues, preparing a fluorescent solvent → adding yellow-green light-storing light-emitting powder Powder and color paste→air drying→grinding and other steps to get finished products that meet the requirements. The specific production method is to carry out the following steps:

[0022] (1) Dissolving the fluorescent powder and preparing the fluorescent solvent: Add 400 grams of yellow fluorescent powder in a closed container containing 1000 ml of thinner water, stir thoroughly for 30 hours, then let it stand for stratification, remove the sediment, and obtain the upper layer Liquid fluorescent solvent;

[0023] (2) Add light-storing luminescent powder: add 450 grams of yellow-green lig...

Abstract

The present invention relates to the preparation process of one kind of high brightness color light accumulating phosphor. The high brightness color light accumulating phosphor consists of phosphor and light accumulating and emitting powder. The preparation process includes preparing fluorescent solvent, adding the light accumulating and emitting powder, drying in air, grinding and other steps. The high brightness color light accumulating phosphor has light color depending on the phosphor, and may have one, two and three kinds of color. During the preparation, flash powder and transparent color slurry may be added. The solvent thinner is used to make the preparation process simple and practical, and make the phosphor and the light accumulating and emitting powder well combined, raise the color of the material and raise the combination of the material with silica gel, organic glass or plastic.

Description

Technical field [0001] The invention relates to a method for making fluorescent light-storing luminescent powder. Background technique [0002] Fluorescent materials have good strong scattering and reflective properties, and are very sensitive to light in the dark. But it does not have the function of luminescence. If there is no light, it will not reflect light. The "Meteor Shower" brand light-storing luminescent powder that has appeared on the market in the last two years is an XL type rare earth ultra-long afterglow light-storing luminescent powder. It is a non-toxic, harmless, non-radioactive, green and environmentally friendly product that is sintered from rare earth silicate combined with electric energy. , after absorbing light for 5-10 minutes, the light-storing luminescent powder can continuously emit visible light to the naked eye for more than 15 hours in the dark, and the initial brightness can reach 20000mcd / m2; in the case of keeping t...
