Abstract

The invention discloses a preparing technology for organic coating of zinc-sulfide long-afterglow luminescent powder. The preparing technology includes the steps that a compound emulsifier is prepared; lauryl sodium sulfate and triethanolamine are dissolved into water and prepared into a transparent solution, the compound emulsifier and an emulsifying assistant are added into high-density oxidized polyethlene wax, the mixture is subjected to high temperature and high pressure and emulsified, then the transparent solution is added, the mixture is stirred, and emulsion is obtained; an ammonia water solution is added into the emulsion, and organic modified emulsion is obtained; an anionic surfactant water solution is added into zinc-sulfide luminescent powder, the mixture is stirred, and slurry is obtained; the organic modified emulsion is added into the zinc-sulfide luminescent powder slurry, a dispersing agent is added, the mixture is cooled to be the room temperature, filtered and dried, and the zinc-sulfide luminescent powder after being coated with the organic emulsion is obtained. The zinc-sulfide long-afterglow luminescent powder is good in dispersity and organic compatibility, and can be evenly dispersed into a base material, the agglomeration phenomenon cannot be generated, and if the zinc-sulfide long-afterglow luminescent powder is added into an organic material, damage to mechanical performance of the material can be effectively reduced.

Description

technical field [0001] The present invention relates to a preparation process of zinc sulfide long afterglow luminescent powder organic coating, in particular, relates to a kind of polymer material which can be used in injection molding, ink paint, printing paste, unsaturated polyester, paint, resin and so on. The invention discloses a preparation process of zinc sulfide long-lasting luminous powder with organic coating on the surface, belonging to the technical field of chemical industry. Background technique [0002] As a safe and environmentally friendly energy-saving product, zinc sulfide long-lasting luminescent powder can be widely used in many fields such as children's toys, various plastic injection molding, luminous ink paints, and coatings. However, as an inorganic powder material and then added to the above-mentioned polymer organic matter process, due to the polar bonds on the surface of the inorganic powder and the non-polar bonds of the organic substrate cannot...
