摘要
介绍一种新型的低渗水聚氨酯灌封材料,该材料为2组分,甲组分为低聚物多元醇与脂肪族异氰酸酯合成的预聚体,乙组分为二胺与二醇复配的固化剂,该材料具有较低的渗水性能。
A new type encapsulating material with low water permeability was introduced in this paper, this material is two-component：（A） a prepolymer synthesized from oligomer polyols and aliphatic diisocyanate; （B）：a compounded ,curing agent of diamine and glycol. The material has very low water permeability.
