Zusammenfassung:	This invention is preparation method of rigid polyurethane foam plastics with rape oil. The procedure is as followings: 1) adds alcohol to alcoholysis with the precence of rape oil and catalysis, obtain mixed unsaturated fatty acid monoester. 2) Add epoxidation agent to get mixed epoxidated fatty acid ester. 3) React with nucleophilic reagent to get mixed hydroxy fatty acid monoesters-biological polyatomic alcohol. 4) Mix with auxiliary catalysis, foam stabilizer and water to form polyether polyol. 5) Mix with foaming agent and isocyanate to obtain rigid polyurethane foam plastics. This invention has a high compatibility with alkane foaming and low cost. It's a good heat insulating material.
