Description

一种高强度瓷绝缘子及其制备方法
技术领域
本发明属于电瓷绝缘子，尤其涉及一种高强度瓷绝缘子及其制备方法。
背景技术
电瓷坯料是指黏土原料和熔剂性原料及其他原料按一定比例组成的混合物，经磨细和混合成为可供制坯用泥料。在确定各种原料比例时必须保证坯料能满足电瓷生产过程所要求的工艺性能和烧成后瓷质的物理性能要求。瓷绝缘子的性能直接取决于黏土原料的品质和用量。
机械强度一直是电瓷生产追求的最重要的性能，因为电瓷材料具有高强度时，在同等电压等级的条件下，可以提高材料的使用率，降低成本。传统的瓷绝缘子，机械强度不高，上釉后对提高电瓷的机、电、热性能效果不好，尤其是不能较大的提高瓷质的弯曲强度。
发明内容
针对上述存在的不足，本发明提供了一种高强度瓷绝缘子及其制备方法，本发明通过控制各电瓷坯料的组分，达到增强瓷绝缘子机械强度的目的。
为了实现上述目的，本发明采用的技术方案如下：
一种高强度瓷绝缘子，其特征在于，主要由如下原料质量份数组成：铝矾土20-30份、氧化锆5-10份、泾阳土10-20份、钾长石5-10份、白胶泥15-24份、黑粘土12-15份、左云土5-10份，矿化剂1-3份，硅酸锆32-38份。
进一步的，所述矿化剂为石灰石、滑石粉、钛白粉、氧化钇中的一种。
进一步的，所述钾长石为低钠钾长石，钠含量小于2.5%。
进一步的，所述瓷绝缘子无釉弯曲强度大于180Mpa，拉伸强度大于113MPa。
进一步的，所述高强度瓷绝缘子的制备方法为：首先将原料按配好的比例称料，加入原料总重量30%的水得到浆料，然后对浆料进行球磨9h,得到的新浆料经过筛除铁后进行榨泥，得到的泥饼在真空练泥机内挤制，得到的泥段再进行电阴干，最后成型、干燥后即得到生坯，生坯经上釉、烧结、胶装后得到所述瓷绝缘子。
进一步的，所述烧结温度在1350℃-1400℃范围之间。
综上所述，本发明由于采用了上述方案，本发明具有以下优点：
本发明瓷绝缘子机械性能好且生产成本低，易于工艺控制。所用原料均为现有的普通陶瓷矿物原料，采用泾阳土，缩短球磨时间，既减少了成本又能改善工艺性能。该配方另一特点是合理匹配不同矿物类型的粘土，是材料具有良好的工艺性能，特别是烧成性能，易于工艺控制，提高瓷绝缘子合格率。
