Toughening column type porcelain insulator and preparation method thereof
The invention relates to the technical field of porcelain insulators, and provides a toughening column type porcelain insulator and a preparation method thereof. The insulator is provided with an insulator body and an insulating layer, and a base material, a filler and a pore forming agent are adopted, so that it is ensured that sintered ceramic contains some fine open pores, the combination of the insulator body and other insulating materials is facilitated, and the strength of the insulator body is not affected; the insulator body is soaked in insulating slurry to obtain the insulating layer, so that the air holes are closed, the strength is ensured, and the insulating property is also improved. By using the raw material with relatively high Al2O3 content, the structure of the obtained insulator is more compact, the stress concentration of the insulator is effectively reduced, and the strength of the insulator is improved; zirconium oxide composite nanoparticles are added to serve as a dispersion phase to reinforce and toughen a matrix, so that the fracture toughness and bending strength of the insulator are improved; and by adding a water reducing agent, the fluidity of the slurry is enhanced, and the surface quality of the sintered insulator is ensured.
本发明涉及瓷绝缘子技术领域，提供了一种增韧性柱式瓷绝缘子及其制备方法。本发明设置绝缘子体和绝缘层，采用基料、填充料和制孔剂，确保烧成后的陶瓷中含有一些细小的开放型气孔，助于绝缘子体与其余绝缘材料的结合，而且也不会影响其强度；绝缘子体在绝缘浆料中浸泡后得到绝缘层，不仅封闭了气孔保证强度，还提高了绝缘性能。通过使用Al2O3含量较高的原料，所得绝缘子的组织更加致密，有效降低了绝缘子的应力集中，提高绝缘子的强度；通过加入氧化锆复合纳米粒子，作为弥散相对基体进行增强韧化，提高绝缘子的断裂韧性、抗弯强度；通过加入减水剂，强化浆料的流动性保证绝缘子烧成后的表面质量。
