摘要:为响应二十一世纪高效、节能、绿色和环保的时代主题，水性紫外光固化体系以其无毒性、无污染、无刺激性和生产安全等优点，在众多的固化体系中脱颖而出，是目前较为活跃的研究和开发领域。本文以二羟甲基丙酸（DMPA）作为亲水单体，聚碳酸酯二元醇（PCDL）或聚醚二元醇（N210），甲苯二异氰酸酯（TDI）为主要原料，采用预聚体法合成不同配比的聚酯型PUA和聚醚型PUA。测试合成乳液的各项性能，将乳液常温干燥放置在紫外灯下交联固化成膜，测试固化成膜的各项性能。结果表明聚酯型PUA和聚醚型PUA均具有良好的耐水性，高固含量。且聚酯型PUA硬度明显高于聚醚型PUA。但是乳液的稳定性和分散性不是很好，长时间放置会出现分层的现象。在这一方面的性能还有待于改善。24760

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
