Title: Stock solution composition for use in production of hard polyurethane foam
Inventor: IMASHIRO YASUO
IPC: C08L75/04
Filed: 1996-09-05
Abstract: A stock solution composition for use in producing rigid polyurethane foams, which enables flame-retardant fillers to remain stably dispersed therein when left to stand still and becomes reduced in the viscosity when stirred or put under an external pressure, thus facilitating in-site liquid feed and urethane foaming. The composition comprises a polyol ingredient, a blowing agent, a flame-retardant filler, and a solvent-swollen clayey mineral as the essential ingredients. The swollen clayey mineral has such thixotropic characteristics that it is a gel as a result of the intermolecular interaction when left to stand still but is converted into a liquid sol as a result of the breakage of the intermolecular interaction when put under an external pressure. By utilizing such characteristics, this composition can maintain a high viscosity when left to stand still, while it can be reduced in the viscosity when stirred or put under an external pressure.
