有机硅改性水性阳离子聚氨酯的合成与性能研究
Synthesis and Use Study of Organo-silicone Modified Water-borne Cationic PU
【摘要】 本研究合成了有机硅改性的阳离子聚氨酯乳液,有机硅的加入改善了漆膜的耐水性、漆膜光泽性和手感,随着有机硅的加入量的增加,漆膜的耐水性提高、吸水率下降,热重分析表明漆膜耐热性提高,FTIR表明乳液中不存在NCO。
【Abstract】 Organo-silicone modified cationic PU latex is synthesized. Addition of organo-silicone improved the water resistance, gloss and touching property of film. With the increase of organo-silicone dosage, water-resistance of film improves and water absorbance decreases. Thermal weight analysis tells that heat resistance improves and FTIR shows no NCO.
