High-toughness conical suspension type porcelain insulator and preparation method thereof
The invention relates to the technical field of porcelain insulators, and provides a high-toughness conical suspension type porcelain insulator and a preparation method thereof. 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; the zirconium oxide composite nanoparticles are added, which belong to fine-structure ceramic materials. The particles are uniform in structure and high in mechanical strength, which serve as a dispersion phase to reinforce and toughen a matrix. The fracture toughness and the bending strength of the insulator are improved. According to the preparation method, a plurality of functional raw materials are compounded, the zirconium oxide composite nanoparticles are modified, and the porcelain insulator which is compact in organization structure and high in strength is obtained through the steps of batch ball milling, coarse grinding, fine grinding and the like.
本发明涉及瓷绝缘子技术领域，提供了一种高韧性圆锥悬式瓷绝缘子及其制备方法。本发明通过使用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，其属于细结构陶瓷材料，结构均匀，具有高的机械强度，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。本发明使用多种功能性原料复配以及对氧化锆复合纳米粒子进行改性，通过分批球磨、以及粗磨和细磨等步骤，得到了组织结构致密、强度高的瓷绝缘子。
