| Abstract: | An ultraviolet curing powder coating UG 1 was prepared with an ultraviolet curing star grafted acrylate resin as a main film forming material.The chemical and physical properties of the coating film were measured.The quantities of the important components such as the ultraviolet initiator , flow modifier affecting the coating film properties , and the melting viscosity changing with different temperatures were inspected . The irradiating time with ultraviolet rays after melting and flow modifying was determined . The results showed that UG 1 ultraviolet curing powder coating's film has excellent chemical and physical properties,The more optimum quantity ( mass ratio ) ranges of the initiator and resin flow modifier are 2.0%～3.0% and 0.6%～0.9% respectively , the melting flow temperature of UG 1 is 110?℃ and the irradiating time with ultraviolet rays after melting and flow modifying is only 3 seconds. |
