摘　　要：以聚醚多元醇、聚酯多元醇和蓖麻油为混合多元醇,以改性MDI(4,4′-二苯基甲烷二异氰酸酯)及PAPI(多亚甲基多苯基多异氰酸酯)为混合异氰酸酯,合成了聚氨酯(PU)胶粘剂预聚体;然后以PA(羟基丙烯酸酯树脂)作为PU预聚体的改性剂,制得高固含量的PUA(聚丙烯酸酯改性聚氨酯)胶粘剂。结果表明:当m(改性MDI)∶m(PAPI)=1∶1、n(-NCO)∶n(-OH)=2.2∶1、w(PA)=8%(相对于PU质量而言)和w(丙烯酸羟乙酯)=3%(相对于PU质量而言)时,PUA胶粘剂的综合性能较好。With polyester polyol,polyether polyol and castor oil as mix polyols,modified MDI（4,4′-diphenyl-methane diisocyanate） and PAPI（multimethylene multiphenyl multiisocyanate） as mix isocyanate,so a poly-urethane（PU） adhesive prepolymer was prepared.Then a PUA（PU modified by polyacrylate） adhesive with high solid content was prepared when PA（hydroxyl acrylate resin） was used as modifier of PU prepolymer.The results showed that the PUA adhesive had well combination property when mass ratio of m（modified MDI）∶m（PAPI） was 1∶1,molar ratio of n（-NCO）∶n（-OH） was 2.2∶1,mass fractions of PA and hydroxy ethyl acrylate were 8% and 3% in PU respectively.
