Method of preparing zinc oxide product by adding nano antimony oxide

Abstract

The invention discloses a method of preparing a zinc oxide product by adding nano antimony oxide. The method comprises the following steps: weighing all components according to mass percentage: 3.5 to4.0 percent of bismuth oxide, 2.7 to 3.7 percent of nano antimony oxide, 1.0 to 1.8 percent of cobalt oxide, 0.6 to 1.3 percent of silicon oxide, 0.6 to 0.9 percent of manganese oxide, 0.8 to 1.4 percent of chromium oxide and other additives and the balance of zinc oxide; mixing all raw materials except the nano antimony oxide; then adding a dispersing agent, an adhesive solution and a defoamingagent, adding purified water to enable the solid content to be 60 to 65 percent and carrying out ball milling; then adding the nano antimony oxide, pulping, tabletting, discharging glue, carrying outhigh-temperature sintering and annealing, coating the annealed resistor disc with a side glass insulating layer and drying the insulating layer; rubbing down two end faces of the resistor disc and spraying aluminum electrodes on the two end faces of the resistor disc by using an arc spraying method, thus obtaining a zinc oxide arrester product. The zinc oxide arrester prepared by the method disclosed by the invention has high potential gradient and good energy absorption capability.

Description

technical field [0001] The invention relates to a method for preparing zinc oxide products by adding nano antimony oxide, which is used in zinc oxide arresters and belongs to the technical field of high-voltage power transmission equipment. Background technique [0002] The main problems existing in my country's lightning arrester products are: the appearance of the equipment is huge, and the space for user wiring in the outlet room is small, so the equipment occupies a large area, the cost of production, transportation and installation is very high, and the consumption of raw materials is large. pose a huge threat. This result is caused by the low potential gradient of the zinc oxide arrester, because the potential gradient of the zinc oxide arrester is too low, and a large enough volume must be used to meet the requirements of a specific voltage, thus causing a waste of resources. [0003] In recent years, in order to achieve the miniaturization of arrester products, many ...
