Description

采用纳米陶瓷材料壳体的超韧保险丝
技术领域
本发明涉及敏感元器件技术领域，尤其涉及一种采用纳米陶瓷材料壳体的超韧保险丝。
背景技术
保险丝作为电路中重要的敏感电子元器件，在电流异常升高到一定的高度和热度的时候，保险丝会自身熔断切断电流，从而起到保护电路安全运行的作用。一般的保险丝，主要包括三个部分：一是熔体部分，它是保险丝的核心，熔断时起到切断电流的作用；二是电极部分，通常有两个，它是熔体与电路联接的重要部件，它必须有良好的导电性，不应产生明显的安装接触电阻；三是壳体(也称支架)部分，保险丝的熔体一般都纤细柔软的，壳体的作用就是将熔体固定并使三个部分成为刚性的整体便于安装、使用，它必须有良好的机械强度、绝缘性、耐热性和阻燃性，在使用中不应产生断裂、变形、燃烧及短路等现象。
现有技术保险丝的壳体，大部分是塑胶、金属材料制成，其综合性能不好。虽然也有一些使用陶瓷材料的保险丝壳体，但其韧性不好，容易断裂，进而限制了陶瓷壳体保险丝的使用范围，例如：汽车等比较颠簸振动的电路中，就不能使用。
发明内容
本发明的目的在于针对现有技术的不足而提供一种采用纳米陶瓷材料壳体的超韧保险丝，从而扩大陶瓷壳体保险丝的使用范围。
本发明的目的通过以下技术措施实现：
一种采用纳米陶瓷材料壳体的超韧保险丝，包括陶瓷壳体，所述陶瓷壳体由以下重量份的原料制成：氧化铝20～30、纳米氧化锆6～10、纳米三氧化二锑1～2、纳米氮化铝13～15、氧化钇1～1.5、聚乙烯醇3～4、异丙醇铝0.5～1、正硅酸乙酯0.6～0.8、去离子水10～15，余量为稀硝酸溶液。
本发明有益效果在于：
本发明的陶瓷壳体通过添加氧化铝、纳米氧化锆、纳米三氧化二锑、纳米氮化铝等成分，使各原料协同作用，有效的提高了复合陶瓷的韧性，最终制备的复合氧化铝陶瓷具有良好的塑性和韧性，抗裂能力更强，特别适用于保险丝的壳体，形成超韧保险丝；采用本发明陶瓷壳体的保险丝，即使在汽车等比较颠簸振动的电路中，也不会断裂。因此，本发明采用纳米陶瓷材料壳体的超韧保险丝，属于敏感元器件领域的关键领先技术，可扩大陶瓷壳体保险丝的使用范围，提高市场占有率。
具体实施方式

本发明的陶瓷壳体由以下几个步骤制备得到：
(1)先将聚乙烯醇、异丙醇铝、正硅酸乙酯与去离子水混合，置于85度水浴条件下，磁力搅拌混合，待混合液的pH值不再变化为止，随后加入稀硝酸溶液，调节体系pH值为4.0，随后水浴升温至100度，继续回流1.5小时得到稳定的铝溶胶备用。
(2)将纳米氧化锆、纳米三氧化二锑、纳米氮化铝与离子液体混合球磨30分钟，随后将其与氧化铝、氧化钇混合，继续球磨分散2小时，最后再将其与步骤(1)制得的铝溶胶混合，再次球磨分散8小时，球磨结束后所得浆料真空脱泡，控制粘度为7000Pa.s，所得浆料进行流延处理，得到胚体。
(3)将制得的胚体在承烧板上以1度/分钟的升温速率升温至500度，保温排胶4小时，随后在1720度的条件下真空保温烧结4小时，出料后即得。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，均属本发明的保护范围。
