Fluorescence coating

Abstract

The invention discloses a fluorescence coating. The fluorescence coating comprises, by weight, 50-60 parts of an acrylic resin, 10-30 parts of phosphor, 5-10 parts of a chaotropic agent, 3-8 parts of an anti-settling agent, 5-15 parts of phenyl methane and 1-5 parts of a curing agent. Nanometer polyethylene phosphate is used as a luminescent material, so the prepared noctilucence coating has a high initial brightness, has a long afterglow time reaching above 10h, has the characteristics of stable color, no radioactivity, heat resistance, environmental erosion resistance, good oxidation resistance, simple preparation technology and stable performances, and can be widely used for indoor and outdoor decoration, indication labels, and the emergency indication of public places.

Description

technical field [0001] The invention belongs to the field of chemical materials and relates to a fluorescent paint. Background technique [0002] With the development of the architectural decoration industry, the paint industry also develops. There are various functional paints on the market, and fluorescent paint is one of them. Currently, there are two main types of energy storage luminescent materials used in the paint industry. That is, zinc sulfide-based luminescent materials and rare earth activated alkaline earth metal aluminate luminescent materials. Zinc sulfide luminescent materials are generally unstable and will turn black under long-term ultraviolet radiation. Zinc sulfide will transform into zinc sulfate, and copper in the crystal lattice will transform into copper oxide. Its chemical composition and crystal lattice of the compound The structure changes so that it gradually loses its luminous properties. Rare earth activated alkaline earth metal aluminate lum...

The safety doors and safe passage signs in ordinary public places are mainly indicated by electric light sources. Once a fire breaks out and the power is cut off, in the case of dense smoke, these fire-fighting signs that rely on power to illuminate will lose their effect, making trapped people Unable to identify the evacuation position and direction in time, thus affecting the escape
