研究了增韧剂、稀释剂及促进剂对环氧灌封胶性能的的影响。以聚氨酯为增韧剂,断裂伸长率较未增韧体系提高80.8%;以502树脂为稀释剂,降低了体系黏度,对断裂伸长率和模量影响不大,断裂强度稍有降低,但剪切强度有所提高,冲击强度则可提高53.1%;以间苯二酚为固化促进剂缩短了剪切强度达到峰值的时间,且峰值强度略有增加。 The effects of toughening agent, diluent and accelerator on the properties of epoxy potting were studied. Polyurethane toughening agent, the elongation at break than the non-toughened system increased by 80.8%; 502 resin as a diluent to reduce the viscosity of the system, the elongation at break and modulus of little effect, the fracture strength slightly reduced, But the shear strength is improved and the impact strength can be increased by 53.1%. Resorcinol as a curing accelerator shortens the time when the shear strength reaches the peak, and the peak intensity slightly increases.
