摘要
通过对沉淀二氧化硅在硅酮胶的应用现状进行了总结,并指出目前商品用的沉淀二氧化硅存在粒径大,硅溶胶含量高,产品分散性差以及金属杂质含量高等缺点,影响了沉淀二氧化硅在硅酮胶中的进一步应用;认为可以通过对沉淀二氧化硅进行超细化加工,高分散处理,以及去溶胶化处理,才能更大程度发掘沉淀二氧化硅的应用潜能,突出沉淀二氧化硅的优势。
The current status of precipitated silica on silicone adhesive was discussed.The results showed that the defects of precipitated silica were agglomerated , big diameter , the high contents of silica sol and metals.It was pointed out that the potential application and advantage of the precipitated silica were full played by the ultrafined , highly dispersed and surface modification treated.
