摘　　要：以4,4′-二苯基甲烷二异氰酸酯(MDI)和聚醚多元醇制备了单组分聚氨酯预聚体。按照配方量将预聚体、填料、增塑剂、偶联剂和催化剂等物质混合,经真空搅拌得到单组分聚氨酯密封胶。单组分聚氨酯密封胶与第1道密封材料(丁基密封胶)的相容性良好。用该密封胶与底涂剂配套使用时,对玻璃和铝具有良好的粘接效果。The one-component prepolymer was prepared with diphenylmethane-4,4＇ -diisocyanate（MDI） and polyether polyol as the main raw matrerials in this paper. The prepolymer, fillers, plasticizer, coupling agent and catalyst were mixed according to the formulation, followed by stirring under the vacuum condition to obtain the polyurethane sealant. The polyurethane sealant exhibits good compatibility with the primary sealing material of butyl sealant. The cooperative use of the polyurethane sealant and the primer has favorable bonding performance to aluminum and glass.
