摘　　要：以异佛尔酮二异氰酸酯(IPDI)和糠胺(KA)为原料合成呋喃环的聚氨酯A组分(FIPF);用IPDI、聚乙二醇(PEG-1000)合成聚氨酯预聚物,以N-羟乙基马来酰亚胺封端,制备聚氨酯齐聚物(B组分)。利用NMR和IR对A和B组分进行结构表征。基于Diels-Alder反应的热可逆性,制备自愈合聚氨酯涂膜材料,并借助NMR、GPC等对其自愈合性能进行考察。Isophorone diisocyanate(IPDI)and furfuryl amine(KA)were the raw material for the synthesis of furan ring polyurethane A group(FIPF);using IPDI and polyethylene glycol(PEG-1000)makes polyurethane pre-polymer,and N-hydroxyethyl maleimide was capping agent,to create polyurethane oligomer(B group points).NMR and IR were used to characterize the structure of A and B.Based on the thermal reversibility of Diels-Alder reaction,the self-healing polyurethane coating material was created,and the self-healing properties were reviewed by NMR、GPC and so on.
