基于聚碳酸亚丙酯二元醇的水性聚氨酯的制备及其在水性木器涂料中的应用研究

Preparation of Waterborne Polyurethane Based on Poly Propylene Carbonate Glycol and its Application in Waterborne Wood Coatings

水性聚氨酯乳液作为水性木器涂料的成膜树脂之一,对木器涂料的性能起着至关重要的作用。采用聚碳酸亚丙酯(PPC)和聚己内酯(PCL)为软段,制备PPC型水性聚氨酯乳液(PPC-PUD),采用动态光散射(DLS)对所合成PPC型水性聚氨酯乳液粒径进行分析,采用所制备的水性聚氨酯作为成膜树脂,添加合适的涂料助剂,配制水性木器涂料,并对涂料性能进行测试。

Waterborne polyurethane emulsion as the main iflm building resin in waterborne wood coatings played an important role for the properties. PPC and PCL as soft parts, waterborne PPC-PUD was prepared. Particle size was analyzed by DLS. The prepared resin as iflm building resin, by adding other additives, waterborne wood coatings were prepared and the properties of the coatings were tested.
