改性聚氨酯植绒胶的研究

Study on Modified Polyurethane Binder for Electrostatic Flocking

由亲油性较好的端羟基聚酯型聚氨酯或有机硅改性聚氨酯作为甲组分，端NCO基聚酯-TDI预聚体为乙组分，固化促进剂复配物为丙组分，配制成三组分静电植绒粘合剂。研究了组分配比、甲组分分子结构、植练工艺等主要因素对值线PVC革制品材湿擦性能的影响，得到了改善耐擦性能的植绒胶。

Electrostatic flocking binders were formulated from three-component compounds, A component is OH-capped hydrophobic polyester-based polyurethane (PU)or polysiloxane modified PU, B is NCocappped prepolymer based on polyester and TDI,C is mixture of curing promoters- The main factors such as ratio of three components,molecular structure of A and the flocking process on the wet-rub fastness property of PVC leather flocking articles were studied. A flocking binder which modified the rub fastness was obtained.
