稀土催化剂在MDI型聚氨酯塑胶跑道材料中的应用研究

Study on application of rare earth catalyst to MDI type polyurethane synthetic rubber sports track material

研究了MDI型聚氨酯塑胶跑道材料中稀土催化剂的固化性能及其对样品物理性能的影响。结果表明:稀土复合催化剂可以完全取代常用的有机Pb/Hg、Pb/Zn和Zn/Sn等复合催化剂体系,从而消除MDI型聚氨酯塑胶跑道材料的生产和使用过程中Pb、Hg污染。

The effeet of rare earth eatalyst on the solidifieation and the mechanical property of MDI type polyurethane synthetic rubber sports track materials were investigated.The result shows that the rare earth composite catalyst can perfectly replace common organic composite catalyst system such as organic Pb/Hg,Pb/Zn and Zn/Su composite catalysts,so as to eliminate the pollution of Pb and Hg in the production and application of MDI type polyurethane synthetic rubber sports track materials.
