Preparation method for black marking glaze for borosilicate glass insulator

Abstract

The invention provides a preparation method for black marking glaze for a borosilicate glass insulator. The preparation method comprises the following steps of: adjusting a proper burdening point by taking various chemical pure oxides as basic raw materials, sintering at the high temperature, and water-quenching to obtain basic glass; smashing and grinding, and mixing the smashed basic glass and an organic solvent to obtain the black marking glaze; and finally printing the prepared marking glaze through a silk screen. The preparation method for the black marking glaze for the borosilicate glass insulator has the advantages that: 1, in the preparation method, the marking glaze is prepared by mixing the organic solvent and an inorganic glass material; the marking glaze prepared by the method is encapsulated by an atmosphere furnace at the high temperature and subjected to post chemical polishing, so letters or numbers marked by the marking glaze are hard to fall off and clear, and short lines and decoloration phenomena are avoided; and the appearance quality of a sealed socket meets the requirements; 2, the marking glaze which is prepared by the method and subjected to the whole test of the sealed socket has no influence on the electric insulation performance; and 3, the marking glaze prepared by the method is directly printed on a glass blank cake, and the glaze is deep black in color, strong in stereoscopic sensation, clear to see words, convenient to operate and simple in process.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of a black marking glaze for borosilicate glass insulators, and belongs to the technical field of new material manufacture and application. Background technique [0002] The sealed socket of the stainless steel shell is the key component of the connection of the electrical circuit. It has high requirements on the performance of the product. The glass insulator and the metal are hermetically sealed, which is far stronger than the conventional seal. The hermetic seal can withstand higher temperatures and Pressure, and can always provide an effective barrier against humid air pollutants or other pollutants. This high-end electrical connector is mostly used in many critical occasions such as aircraft, petrochemical, and electronic industries. [0003] Borosilicate insulating glass has the advantages of good insulation, strong voltage resistance, good chemical stability aga...

Problems solved by technology

However, due to the high sintering temperature in the sealing process, ordinary organic colorants decompose at high temperatures and fail to achieve the purpose of marking; while ordinary inorganic colorants will reduce the surface resistance of the insulator, and the post-processing of the sealed socket During the process, after chemical polishing and gold-plated pins, it is easy to cause marking numbers and letters to fall off, which cannot meet the marking requirements
