用于聚氨酯发泡轮胎的微孔泡沫的合成研究

Study on the Synthesis of Microcellular Polyurethane Elastomer Tyre

采用低不饱和度、高相对分子质量聚醚多元醇和纯二苯基甲烷二异氰酸酯(MDI),合成了聚醚型聚氨酯微孔弹性体材料。该聚醚型微孔弹性体泡沫材料具有优异的力学性能,可用于自结皮微孔弹性体轮胎的制备。

The polyether-type polyurethane （PU） microcellular elastomer was prepared by low unsaturated, high molecular weight polyether polyols and pure MDI. This kind of polyether-type PU microcellular elastomer had excellent mechanical properties and could be used for the preparation of the polyurethane foam tyres.
