摘要
采用预聚体法,通过引入聚醚改性羟基硅油(S-900),合成有机硅改性水性聚氨酯(WPU);系统研究了不同异氰酸酯值(R值)、不同聚酯/聚醚多元醇软段以及S-900的用量,对WPU乳液性能和应用性能的影响。结果表明:当R值为1.6,选用聚己二酸-2-甲基丙二醇酯(PMA2000)为聚酯多元醇软段,S-900加量为6%时所得水性聚氨酯综合性能优异,将其应用于水性合成革时,产品的环保性、剥离强度、耐寒性、耐摩擦色牢度等,均超过了QB/T 2958-2008《服装用聚氨酯合成革》的指标要求。
Organosilicone modified WPU was successfully synthesized by the prepolymer method with polyether modified hy- droxy silicone oil（ S - 900）. The effects of R value, polyester or polyethe polylol as the soft segment and the amount of polyether modified hydroxy silicone oil on WPU emulsion properties and application properties were systemically investigated. The results show that the good organosilicone modified WPU is prepared when the R value is 1.6, the PMA2000 is used as the soft segment and the the amount of S -900 is 6%. Then, the organosilicone modified WPU was applied on the waterborne synthetic leather. The resultant products get excellent properties, whose environmental protection, resistance to peeling, low temperature resistance and color fastness to rubbing are above the requirement of QB/T 2958 -2008 standard.
