技术领域
本发明涉及电瓷技术领域，更具体的，涉及一种电瓷绝缘子及其制备方法。
背景技术
在现有技术中，绝缘子是一种特殊的绝缘控件，能够在架空输电线路中起到重要作用。现在发展为高压电线连接塔的一端挂了很多盘状的绝缘体，它是为了增加爬电距离的，通常由陶瓷制成。绝缘子不应该由于环境和电负荷条件发生变化导致的各种机电应力而失效，否则绝缘子就不会产生重大的作用，就会损害整条线路的使用和运行寿命。瓷绝缘子在架空输电线路中起着两个基本作用，即支撑导线和防止电流回地。瓷绝缘子由绝缘瓷体和金属附件组成，绝缘瓷体表面有多个、间隔、突出的圆形伞裙。绝缘瓷体原料选择不同，其机械性能、电气性能不同，合理选用原料是保证产品性能、使用安全的重要保障。本类产品种类繁多，配方各异，达标才是产品质量的保证。
绝缘子是电力系统的重要零部件。在现有的电机传动的电力机车中普遍使用的是橡胶、树脂等有机高分子复合材料绝缘子，这种绝缘子相对传统的陶瓷绝缘子具有制造工艺相对简单、成型比较容易、产品质量可靠性较高等优点。但是，有机高分子材料本身存在着明显的缺点，如耐温、耐老化性能差。一般的有机绝缘材料最高使用温度不超过300℃，并且当温度较高时其使用寿命也大打折扣。而随着环境温度上升，有机高分子材料的老化速度加快，使用寿命缩短，并产生开裂、机械、电气性能下降等问题，严重影响产品的质量稳定性，无法完全满足新型高速电力的需求。
