Title
(EN) Multiphase structure UV curable powder coating resin and preparation method thereof
(ZH) 一种多相结构UV光固化粉末涂料树脂及其制备方法
Abstract
(EN) The invention discloses a multiphase structure UV curable powder coating resin and a preparation method thereof. The preparation method comprises the following steps of: (1) heating a liquid UV resinand an emulsifier, conducting dispersing, adding deionized water while dispersing, and performing emulsifying to obtain an emulsion of the liquid UV resin; (2) melting and dispersing solid UV resin, aphase change agent, the emulsifier and deionized water, adding the emulsion of the liquid UV resin, fully and uniformly mixing the substances by stirring, and performing cooling in the stirring process to obtain a suspension; (3) carrying out filter pressing on the suspension to obtain a filter cake; and (4) drying and grading the filter cake to obtain the multiphase UV curable powder coating resin. Correspondingly, the multiphase structure UV curable powder coating resin is prepared by the method. By the adoption of the method, the performance of liquid UV resin and the performance of powdercoating resin are both achieved, spraying construction can be conducted in a powder coating mode, the utilization rate of the resin is increased, and the environment cannot be affected.
(ZH) 本发明公开了一种多相结构UV光固化粉末涂料树脂及其制备方法,包括:(1)将液体UV树脂和乳化剂加热,并进行分散,边分散边加入去离子水进行乳化,得到液体UV树脂的乳化液;(2)将固体UV树脂、相变剂、乳化剂和去离子水熔融分散,并加入液体UV树脂的乳化液,通过搅拌使其充分混合均匀,并在搅拌过程中降温,得到悬浮液;(3)将悬浮液进行压滤,得到滤饼;(4)将滤饼进行干燥和分级,得到多相UV光固化粉末涂料树脂。相应的,本发明多相结构UV光固化粉末涂料树脂是由上述方法制得。采用本发明,兼具液体UV树脂以及粉末涂料树脂的性能,能采用粉末涂料的方式进行喷涂施工,提高树脂的使用率,且不会对环境造成影响。
