A Catalytically Active Tertiary Amino- and Polyether-Modified Silicone Surfactant and Its Application in Polyurethane...

In this paper, a polyether- and tertiary amine-modified silicone surfactant was studied, which had both the surface properties and catalytic properties of the polyurethane reaction. A series of surfactants were synthesized, and their structures were characterized. The performance of the surfactant was discussed by testing its static and dynamic surface tension. The catalytic efficiency was verified by infrared dynamic tracking of the isocyanate reaction process. Finally, the prepared polyether- and tertiary amine-modified silicones were used as surfactants in the polyurethane rigid foam formula, and it was found that the use of organic amine catalysts could be greatly reduced. Therefore, the volatile organic content emission of rigid polyurethane foam can be reduced, and the surface defects of the rigid polyurethane can be improved.
