Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] a. Preparation of bonding glaze

[0019] According to the composition of Table 1, four formulations of inorganic bonding glazes were prepared. After mixing clay, potassium feldspar, quartz, alumina, talc, calcite, fluorite, and pigments, the mixture was mixed with material: ball stone: water = 1: 1.8 : 1 ratio for ball milling, and the ball milling time was 48 hours. The ball-milled slurry is baked in an oven at 100°C until it becomes a paste-like viscous body. The pigment is a commercially available product of iron chromium manganese oxide, and the color is brown.

Abstract

The invention discloses inorganic sticking glaze for high voltage electronic porcelain, and the inorganic sticking glaze has high temperature resistance and aging resistance. The invention comprises the following ingredients according to the weight percentage: clay of 20 to 28 percent, potassium feldspar of 20 to 28 percent, quardz of 20 to 28 percent, pencil stone of 3 to 5 percent, calcite of 3to 5 percent, fluorite of 5 to 8 percent, alumina of 5 to 12 percent and colouring matter of 0 to 10 percent. The sticking glaze is made into material slurry through ball grinding so as to be used forhigh voltage electronic porcelain sticking; the sticking glaze has certain liquidity, thereby being beneficial for generating the middle transition layer of the electronic porcelain sticking face andimproving the intensity of the insulator bonding. The invention adopts a V shaped joint face tie-in, which is beneficial for the improvement of the porcelain intensity after the sticking of the sticking product, so as to solve the problem that the traditional organic sticking agent has bad aging resisting performance.

Description

technical field [0001] The invention relates to an inorganic bonding glaze for a high-voltage porcelain sleeve and a bonding method for the porcelain sleeve. Background technique [0002] For many years, Western Porcelain has been using organic bonding glazes for bonding large high-voltage porcelain sleeves. Although the strength of organic bonding products can meet the product requirements, it has the disadvantage of poor aging resistance. With the continuous improvement of the voltage level of power transmission and transformation projects, power equipment OEMs are more inclined to use inorganic adhesive porcelain sleeve products with high strength and excellent aging resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inorganic bonding glaze for high-pressure porcelain sleeves with high temperature resistance and aging resistance. After firing at high temperature, the bonding glaze has certain fluid...
