Description

一种热密封性良好的电容器金属化薄膜及其制备方法
技术领域
本发明涉及电容器制造领域，特别是一种热密封性良好的电容器金属化薄膜及其制备方法。
背景技术
电容器用双向拉伸聚丙烯薄膜具有较高的机械性能和电气性能，与普通型薄膜制得的电容器相比，用聚丙烯薄膜制得的电容器以其热收缩率低、性能稳定、耐高温、耐高压，防止击穿等显著优点，使得聚丙烯薄膜制得的电容器的使用范围越来越广。
现有的聚丙烯电容薄膜，收缩率相对偏大、耐温性差，用此膜卷绕而成的电容器随着其工作时间的加长，其内部温升较快，导致电容器的稳定性急剧下降，甚至造成电容器失效，给电器整机或电网带来严重的安全隐患。因此对做为电介质的聚丙烯薄膜的耐温性能提出了更高的要求。
发明内容
本发明的目的是提供一种热密封性良好的电容器金属化薄膜及其制备方法。
为了实现本发明的目的，本发明通过以下方案实施：
一种热密封性良好的电容器金属化薄膜，由下列重量份的原料制成：等规聚丙烯200、聚乙烯醇3-4、乙烯基三乙氧基硅烷1-2、异辛基聚氧乙烯醚2-3、椰油酸单乙醇酰胺1-2、柠檬酸钾1-2、十溴二苯乙烷1-2、异氰酸酯2-3、助剂5-6；
所述助剂由下列重量份的原料制成：茂金属线性低密度聚乙烯12-15、防老剂ODA 1-2、磷酸三甲酚酯2-3、椴木灰烬1-2、硅烷偶联剂KH550 1-2、环氧亚麻油1-2、玫瑰精油0.1-0.2；制备方法是将茂金属线性低密度聚乙烯加热至熔融状态，加入其它成分，搅拌分散均匀，冷却，造粒，即得。
本发明所述热密封性良好的电容器金属化薄膜，由以下具体步骤制成：
（1）将等规聚丙烯、聚乙烯醇、乙烯基三乙氧基硅烷、异辛基聚氧乙烯醚加热熔融，再加入助剂以及其余剩余成分充分搅拌，送入挤出机熔融、过滤，然后再通过挤出机挤出片状熔体，过滤>1200目，所述挤出机的温度为220-260℃；
（2）将步骤（1）制成的片状熔体通过激冷辊及风淋室冷却定型后制得铸片，依次进行纵向拉伸、横向拉伸、粗化面电晕处理；
（3）收卷、第一次时效处理、第二次时效处理；
（4）真空蒸发金属化膜，粗化面形成金属化层。
本发明加工工艺简单,并且用其制作的薄膜电容器接触电阻小,从而使得产品特性好，同时添加了助剂，增强了薄膜的阻隔性和气密性，具有良好的耐压性和耐冲击性，同时具有热封强度高、热封性能好的特点，抗击穿，耐高温，使用寿命长。
