Semiconductor glaze of suspension type porcelain insulator and preparation method of semiconductor glaze

The invention provides semiconductor glaze of a suspension type porcelain insulator and a preparation method of the semiconductor glaze, and relates to the technical field of semiconductor glaze. The semiconductor glaze of the suspension type porcelain insulator comprises a glaze raw material, a conductive metal oxide filler, a wear-resistant filler and a cosolvent, and the mass ratio of the glaze raw material to the conductive metal oxide filler to the wear-resistant filler to the cosolvent is (45-60):(15-30):(12-16.5):(14-18.5). The glaze raw materials added with calcined zinc oxide, lithium chinastone and spodumene have small contractility, pinholes and cracks are not easy to appear on the glaze surface, the hydrophobicity and dustproof effect of the glaze surface are ensured, so that the occurrence probability of flashover is reduced, and the mechanical strength, hardness and wear resistance of the glaze are further enhanced by adding silicon dioxide, zirconium silicate and boron carbide into the glaze ra
