摘要
合成了改良型Karstedt催化剂,考察了其在有机硅灌封树脂制备中的催化活性,分析了催化剂用量和反应温度对胶料反应固化过程表观黏度的影响,并用其催化制备了室温固化透明有机硅灌封树脂材料。结果表明,该催化剂符合室温固化有机硅灌封树脂的操作要求,可制备出性能良好的透明有机硅灌封树脂材料。
The improved Karstedt catalyst was synthesized. And its catalytic activity in the preparation of organicsil- icon potting compound was studied. Meanwhile the influence of the catalyst content and reaction temperature on the silicone resin curing process were investigated. And the transparent RTV organicsilieon potting material was prepared by using the catalyst. The results suggested that the catalyst met the operation demands of RTV organicsilicon potting compound, and the transparent organicsilicon potting material with excellent performances was obtained.
