电装主接线头灌封聚氨酯橡胶的研制

Polyurethane rubber research of terminal switch sealant for power assembly

主要介绍了电装主接线头灌封聚氨酯橡胶（ＧＢ－８）的国产化研制，讨论了ＮＣＯ％含量及ＮＨ２／ＮＣＯ之比对ＧＢ－８物理性能的影响。

In this paper the development domestically of polyurethane rubber(GF-8)of terminal switch sealant for power assembly is reviewed,The effect of NCO content and the ratio of NH 2/NCO on the physical properfies of GF-8 polyurethane rubber,It is found that GF-8 polyurethane rubber is simiar to imports products in the physical property and electrical properties.
