摘要
本文通过在端乙烯基聚二甲基硅氧烷中,添加聚合物与有机硅树脂,以此作为交联剂,并选用氢氧化铝作为阻燃填料,增加铂乙烯基配合物作为催化剂,选择氮化硼与空心玻璃微珠作为辅助,最终实现轻量化灌封胶的制备。本文主要对此灌封胶制备进行了详细分析,并在此基础上,深入探究了灌封胶性能的影响因素,即氮化硼、铂乙烯基配合物、空心玻璃珠等。结果表明,在端乙烯基聚二甲基硅氧烷为100份,聚二甲基硅氧烷为16份,氢氧化铝为120份,氮化硼为30份,有机硅树脂为5份,空心玻璃微珠为45份,铂乙烯基配合物为1.5份时,所得基于汽车锂电池的轻量化灌封胶的整体性能处于最佳状态。
In this paper, polymer and silicone resin were added to vinyl-terminated polydimethylsiloxane as crosslinking agent, aluminum hydroxide was selected as the flame retardant filler, platinum vinyl complexes were added as catalyst, boron nitride and hollow glass beads were selected as auxiliary, and the preparation of lightweight pouring sealant was finally realized. In this paper, the preparation of pouring sealant was analyzed in detail, and on this basis, the factors affecting the performance of pouring sealant, namely boron nitride, platinum vinyl complexes, hollow glass beads, etc. Results show that the end of the vinyl polydimethylsiloxane of 100, polydimethylsiloxane as 16, aluminum hydroxide for 120, boron nitride as 30, organic silicon resin as five copies, hollow glass beads to 45, 1.5 for vinyl platinum complexes, the car lithium-ion batteries based lightweight potting glue the overall performance of the optimum state.
