摘　　要：采用环氧改性聚氨酯胶黏剂制备了耐冷媒柔软复合材料,研究耐冷媒胶黏剂制备的影响因素及产品复合工艺,并对其耐冷媒性能进行测试。结果表明:采用质量分数为1.5%的促进剂C与环氧树脂C制备的改性环氧胶耐冷媒性能较好;当改性环氧胶与聚氨酯胶的固体含量比为2∶8时,耐冷媒胶黏剂制得的样品综合性能最佳。其最佳复合工艺温度为:Ⅰ区80℃、Ⅱ区85℃、Ⅲ区90℃。制备的耐冷媒复合材料NMN、NHN常规性能合格;耐冷媒测试后,其外观无明显变化、无分层和开裂现象,且其击穿电压和拉伸强度保持率均不低于85%、质量损失率不超过1.5%,耐冷媒性能优于市场上同类产品。Refrigerant resistant combined flexible materials were prepared using epoxy resin modified poly-urethane adhesive. The influencing factors of preparing refrigerant resistant adhesive and the composite technology of product were studied, and its refrigerant resistance was also tested. The results show that the modified epoxy resin adhesive prepared by 1.5% of accelerator C and epoxy resin C has good refrig- erant resistance. When the solid ratio of modified epoxy resin adhesive and polyurethane adhesive is 2：8, the samples prepared by refrigerant resistant adhesive have the best comprehensive performances. The best technical parameters of temperature from zone 1 to zone 3 are 80℃, 85℃ and 90℃, respectively. The conventional performances of refrigerant resistant combined flexible materials such as NMN and NHN are qualified. After the refrigerant resistance test, there is no obvious change, no delamination, and no cracking, the retention rates of breakdown voltage and the tensile strength are no less than 85%, the mass loss rate is no more than 1.5%. Therefore, the refrigerant resistances of them are better than that of the similar products on market.
