纯环氧VPI浸渍树脂的研制及性能测试

摘要

介绍了一种无酸酐无易挥发性稀释剂的纯环氧VPI浸渍树脂。通过优选环氧活性稀释剂及自制固化剂，制备一种黏度适中、不易吸潮、储存稳定，且具有优异的电气性能和机械性能的纯环氧VPI浸渍树脂。该树脂性能与环氧酸酐树脂性能相当，是环氧酸酐VPI浸渍树脂理想的替代品。%An epoxy VPI resin without anhydride and volatile thinner was introduced. By optimally selecting active epoxy diluting agent and self-made curing agent, the epoxy VPI resin with moderate viscosity, moisture resistance, good storage stability, excellent electrical and mechanical properties was prepared. The performance of the resin as mentioned is equal to that of epoxy anhydride resin, it is an ideal substitute of epoxy anhydride VPI resin.
