Problems solved by technology

But this luminous energy storage dye has several obvious disadvantages: 1. When the light is turned on during the day or night, there is no luminous effect; 2. The luminous intensity is very low, and the luminous effect is very weak; 3. The luminous duration is very short , the luminous effect will not be visible after a few hours; 4. The validity period of the ink layer is very short, and the energy storage effect of the ink layer will be greatly reduced after 2 to 3 months, which will obviously affect the luminous effect at night

Abstract

The invention relates to electroluminescent water-based ink and wallpaper, and a preparation method and application of the electroluminescent water-based ink. The electroluminescent water-based ink comprises the following raw materials in percentage by weight: 30-40% of a water-based emulsion, 5-20% of an electroluminescent substance, 1-10% of a dispersing agent and 30-60% of a solvent. The preparation method comprises the following steps: adding the water-based emulsion into a stirring barrel, carrying out stirring, sequentially adding the electroluminescent substance, the dispersing agent and the solvent into the stirring barrel, carrying out uniform stirring, and finally carrying out filtering by using a 200-mesh screen. The prepared electroluminescent water-based ink can be used for preparing the electroluminescent wallpaper. The wallpaper prepared from the electroluminescent water-based ink provided by the invention has a soft luminescent effect. The wallpaper can emit light continuously as long as a 12-V weak current is applied to the two ends of the wallpaper, is not influenced by temperature, humidity, ultraviolet rays and light emitting time, and is convenient to use likea household common fluorescent lamp.

Description

technical field [0001] The invention relates to the formulation and preparation method of ink, in particular to electroluminescent water-based ink, wallpaper, preparation method and application. Background technique [0002] With the continuous development of the national economy and the continuous improvement of people's living standards, a large number of commercial housing, hotels, and exhibition halls have emerged, and people's requirements for interior decoration materials have continued to increase. As an important part of modern interior decoration materials, wallpaper has become more and more popular. people's attention. Because wallpaper has good decorative effect, convenient construction and environmental protection, it has been more and more widely used. From the initial use in hotels, office buildings, exhibition halls and other public places, it is now increasingly used in ordinary residential buildings. However, in addition to the appearance of the wallpaper ...
