Synthesis and Development of High-Performance Waterborne Wood Coatings
Abstract: In response to the twenty-first century, High efficiency, energy saving, green and eco-friendly theme of the times, Waterborne UV-curing systems non-toxic, non-polluting, safety and non-irritating etc. come to the forien many curing system, which is more active in the Research and development field. As ahydrophilic monomer is DMPA for This article, PCDL and N210 and TDI are mainly raw material, then gain different proportions of polyether type of PUA and polyester type of PUA. Test to emulsion for every performance. The emulsion was dried at room temperature then put them under UV irradiation to film curing. Result show that both emulsions has good water resistance and high solid content. Beside hardness of polyether type of PUA is better than polyester type of PUA. While the emulsion stability and dispersed is not good ,and it happen to layer phenomenon in emulsions .this side need to be improved.
Key Words: High Performance ; PUA emulsion;; Water-based paint; Film properties; UV Curing
