高绝缘、耐低温浇注胶的防开裂

CRACKING PREVENTION OF POTTING MATERIALS WITH EXCELLENT INSULATING PERFORMANCE AND FREEZE RESISTANCE

从树脂、增韧剂、填料及固化剂的种类和用量等方面讨论了如何降低固化收缩应力及低温收缩应力，从而减少因固化收缩和冷冻收缩引起的开裂现象，以保持所合成浇注胶固化物在常温和低温下的高绝缘性能。

This article discuss how to lower the curing shrinkage internal stress and freezing shrinkage internal stress of the product to prevent its cracking resulted from curing and freezing shrinkage, to maintain the excellent insulating performance of the solidified potting materials beth in ordinary temperature and in freezing conditions, focused on the influence of the variety and addition level of resin, plasticizer, filler and solidifier.
