摘要
使用碳化二亚胺改性MDI(液化MDI)与聚碳酸亚丙酯二元醇(PPC)合成了一种不含VOC的可在露天常温环境下进行光-湿固化的聚氨酯预聚体,其制备的跑道涂层拉伸强度达到了1.5MPa,断裂延伸率97%,邵氏硬度74HA,性能优异且环境友好,具有较好的市场应用价值。
A VOC-free photo-moisture curable polyurethane prepolymer is prepared by using carbodiimide modified MDI（liquefied MDI） and poly propylene carbonate（PPC） as raw materials.The prepared prepolymer shows the tensile strength up to 1.5 MPa, the elongation at break 97% and the Shore hardness 74 HA. Meanwhile, the environmental friendly photo-moisture curable polyurethane exhibits excellent performance and has a good application prospect.
