Abstract

The invention discloses a preparing technology of organic coating of high purity industrial product zinc sulfide powder. Firstly, polyethylene powdery material with small molecular weight and high density as well as catalyst are heat in the reaction kettle to increase temperature, afterwards oxidizing agent (hot air, O2 or H2O2) is introduced to prepare oxidized polyethlene wax, the prepared oxidized polyethlene wax is added into emulsifier, polymerization inhibitor, co-emulsifier and the like, emulsification is conducted under status of heating and stirring to obtain oxidized polyethlene wax emulsion, then the oxidized polyethlene wax emulsion is atomized to conduct spraying of the high purity industrial product zinc sulfide powder, so that organic coating of the high purity industrial product zinc sulfide powder is achieved.
