Description
技术领域
本发明涉及橡胶复合材料加工领域，特别是一种氟橡胶电容器密封垫及其制备方法。
背景技术
电容器通常简称为电容，是电子设备中大量使用的电子元件之一，广泛应用于电路的隔直通交、耦合、旁路、滤波、调谐回路、能量转换、控制等方面。电容器由壳体、电容芯子、端盖及接线端子组成，电容器壳体内装有浸渍介质，浸渍介质一般为植物油或矿物油，电容器的密封部位均设有密封垫或密封圈，由于电容器的工作环境千差万别，有的电容器需要在恶劣的环境下工作，电容器密封垫需要耐高温、耐寒、耐酸碱、耐盐雾等有不同要求。
发明内容
本发明的目的是提供一种氟橡胶电容器密封垫及其制备方法。

所述改性凹凸棒土由下列重量份的原料制成：凹凸棒土30-34、二苯基甲烷二异氰酸酯3-4、二缩三丙二醇二丙烯酸酯3-4、三聚磷酸钠5-6、玉石4-5、硅烷偶联剂KH-5501-2、碳化硅4-5、2，6-二叔丁基对甲酚1-2、吗啉1-2、硫醇丁基锡1-2、当归油1-2；制备方法是将凹凸棒土、玉石放混合入煅烧炉中在700-720℃下煅烧3-4小时，冷却，放入10-12%盐酸溶液中浸泡1-2小时，过滤取出，用清水洗净烘干，粉碎成200-300目粉末，与其它剩余成分混合，研磨分散1-2小时，即得。
本发明所述氟橡胶电容器密封垫，由以下具体步骤制成：将氟橡胶、氧化镁、促进剂BPP、甲基乙烯基硅橡胶加入密炼机中，加热至30-40℃，混炼3-5min；然后升温至40-50℃，再加入电石废渣、氨基磺酸、半补强炭黑、菜籽油、硫化剂BP、促进剂TMTD，混炼6-8min，再加入双巯基乙酸异辛酯二正辛基锡继续混炼4-6min；加入其余剩余成分混炼5-6min，即得本发明橡胶料。
本发明的优异效果是：本发明添加改性凹凸棒土，改善了胶料的工艺性能，使用环保型配合剂，减少其毒副作用和对环境的污染；本发明采用氟橡胶，具有较好的耐油性，而且生产效率高，使用寿命长，应用前景广泛。
