聚氨酯改性水性醇酸树脂涂料的性能及应用

Performance and Application of Polyurethane Modified Waterborne Alkyd Resin Coatings

以聚氨酯改性水性醇酸树脂PUA-1642为成膜物质,制备了水性醇酸树脂涂料。讨论了催干剂、消泡剂、不同颜基比对涂料性能的影响。选择ZH-101为催干剂,干燥性能优异,BYK-028为消泡剂,漆膜外观正常。不同颜基比下的涂料性能均满足行业标准要求,有较大的配方设计空间根据使用性能要求进行配方调节。聚氨酯改性水性醇酸树脂涂料具有干燥快、储存期长、耐水性好、极低VOC等优点,在水性工业轻防腐领域已经大规模应用。

Polyurethane modified waterborne alkyd resin PUA-1642 was choseas a film-forming substance and a waterborne alkyd resin coating was prepared.The effects of driers,defoamersand different pigment base ratios on the properties of the coating were discussed.When ZH-101 was a drier,the drying performance was good.When BYK-028 was an antifoaming agent,the paint film looked normal.Coating properties in different pigment base ratios met the industry standards,there was a large design space to adjust the formulation according to the performance requirements.Polyurethane modified waterborne alkyd resin coating had the advantages of fast drying,long storage period,good water resistance and very low VOC.It had been applied on a large scale in the field of light industrial anti-corrosion.
