Abstract

The invention provides a preparation method for a super-hydrophobic self-luminous coating. The method comprises the following two steps of 1, uniformly mixing a high-molecular polymer monomer, a cross-linking agent, an initiating agent, nano-particles and long-lasting phosphor materials to obtained a mixture; 2, uniformly coating the surface of a base material with the mixture, and carrying out polymerization to obtain the super-hydrophobic self-luminous coating. The preparation method for the super-hydrophobic self-luminous coating overcomes the shortcomings of the prior art, the application range of the long-lasting phosphor materials is widened, and meanwhile the problem that the super-hydrophobic self-luminous coating is decomposed or the luminous intensity is reduced when water is encountered is solved. The preparation method for the super-hydrophobic self-luminous coating is simple in process and high in universality, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to a method for preparing a superhydrophobic self-luminous coating by coating and doping a long-lasting luminescent material, and belongs to the technical field of coatings. Background technique [0002] Long afterglow luminescent material is a "green" light source material, that is, it stores light radiation energy under the irradiation of natural light or artificial light source. When the light source is cut off, it can still release the stored energy in the form of visible light, showing bright and recognizable light. , is an ideal emergency light source. With the deepening of research in recent years, the afterglow time has also increased from a few seconds to more than ten hours. It has lighting function and can play the role of emergency indication. However, many long-lasting luminescent materials with excellent luminous performance are very sensitive to water, easy to decompose in humid air, weaken luminescence, and finall...
