Beschreibung
Zusammenfassung:	The invention provides a preparation method of an oil-resistant and seawater-resistant polyurethane-based composite material, which comprises the following steps: preparing an isocyanate-terminated prepolymer from polycarbonate diol, isophorone dichloride and bis (hydroxymethyl) butyric acid; then nano particles or precursors of the nano particles are added for in-situ polymerization to prepare nano particle/polycarbonate type waterborne polyurethane hybrid resin, the nano particle/polycarbonate type waterborne polyurethane hybrid resin is compounded with liquid crystal polymer fibers, and the flexible composite material is prepared through a coating process. The prepared oil-resistant and seawater-resistant polyurethane-based composite material can be applied to underwater oil storage bags, such as storage of crude oil and product oil, development of ocean (marginal) oil fields, long-term storage and replenishment of island fuel and the like. The high and low temperature performance is excellent, and the usa
