Toughening rod type porcelain insulator and preparation method thereof
The invention discloses a toughening rod type porcelain insulator and a preparation method thereof, and relates to the field of insulators, raw materials are uniformly mixed, blank making, glazing and firing are carried out to prepare a primary blank, the surface of the primary blank is continuously coated with sol containing crystalline flake graphite, and heat treatment is carried out after drying to prepare the rod type porcelain insulator. According to the method, the surface of the initial blank is continuously coated with the sol containing the crystalline flake graphite, on one hand, the sol can form a continuous film on the surface, on the other hand, the crystalline flake graphite covers open holes formed after firing, a matrix is more compact, and the mechanical bending strength of the insulator is enhanced.
本发明公开了一种增韧性棒型瓷绝缘子及其制备方法，涉及绝缘子领域，将原料混合均匀，制坯，施釉，烧成，制得初坯，继续在初坯表面涂覆含有鳞片石墨的溶胶，干燥后进行热处理，制得棒型瓷绝缘子。本发明通过在初坯表面继续涂覆含有鳞片石墨的溶胶，一方面能够使得溶胶在表面形成连续的膜，另一方面鳞片状石墨覆盖烧制后出现的开放性孔，使基体更加致密，增强绝缘子的机械弯曲强度。
