Abstract

The invention discloses a sizing agent for a long-afterglow luminescent panel and a preparation method. The sizing agent is characterized by being prepared from the following raw materials by weight percent: 44-75 percent of long-afterglow fluorescent powder, 0.2-1 percent of carrier and 24-55 percent of chelant. The preparation method comprises the following steps: (1) cleaning a substrate; (2) printing the sizing agent by using screen printing, and drying; (3) printing one layer or three layers of the long-afterglow luminescent sizing agent; (4) sintering the substrate printed and dried in the step (3); and (5) printing a layer of varnish on the sintered substrate, and drying to obtain the long-afterglow luminescent panel. The long-afterglow luminescent panel prepared by the method can illuminate at night, and the preparation method is simple with low cost.

Description

technical field [0001] The invention relates to a preparation technology of a long afterglow light-emitting panel, and to a fluorescent paste for a long-afterglow light-emitting panel. Background technique [0002] At present, the light-emitting panel is a new operation interface of electronic complete machine products that has become popular in recent years. It integrates switch buttons, panel function text, marks, trademarks, transparent windows and displays. Due to Light-emitting panels have the characteristics of durability, small size, light weight, and low cost. They are increasingly used in instrumentation, electromechanical products, computers, office equipment, electronic toys, and household appliances. [0003] The light-emitting panels currently available on the market usually use backlight lighting or electroluminescence for the convenience of working at night, which not only increases the difficulty in production, but also increases the production cost. Therefo...
