Glass composition, glass powder, glass ink and application of glass ink

Abstract

The invention provides a glass composition, glass powder, glass ink and application of the glass ink, and belongs to the technical field of glass ink. The glass composition and the glass powder are prepared from the following components in percentage by mass: 35 to 45% of SiO2, 25 to 35% of Bi2O3, 5 to 15% of B2O3, 4 to 8% of ZnO, 2 to 8% of Na2O, 2 to 5% of K2O, 0.5 to 2.5% of Li2O, 1 to 4% of TiO2, 0.5 to 5% of Al2O3 and 1 to 3% of ZrO2. The glass powder has lower glass transition temperature and better acid and alkali corrosion resistance under the condition of not containing harmful components such as lead, mercury, cadmium, hexavalent chromium, fluorine and the like. The glass ink comprises the glass powder, and when the glass ink is applied to preparation of a glass film on the surface of a base material, the sintering temperature of the glass ink can be effectively reduced, and the acid and alkali corrosion resistance of a glass film material obtained through sintering can be improved.

Description

technical field [0001] The present application relates to the technical field of glass ink, in particular, to a glass composition, glass powder, glass ink and the application of the glass ink. Background technique [0002] As an important part of glass ink, glass powder enables the ink to form glass film and crystallization when sintered at high temperature, endows the ink with anti-adhesion and chemical corrosion resistance, and is an important factor affecting the performance of the ink. [0003] In traditional commercial glass, a large amount of PbO is often added as a glass flux oxide to achieve a low melting point. However, with the enhancement of environmental protection awareness and the implementation of environmental protection policies, more and more attention has been paid to environmentally friendly and harmless lead-free low-temperature glass, and higher requirements have been put forward for the environmental protection of inks. [0004] Based on the above bac...

AI Technical Summary

Problems solved by technology

However, the currently proposed lead-free glass ink usually has a great impact on the acid and alkali resistance of the glass when the sintering temperature is adjusted, resulting in either the sintering temperature is too high or the glass film material obtained by sintering has a high resistance to acid and alkali. Poor acid and alkali corrosion

In order to improve the above problems to a certain extent, some existing lead-free glass inks usually add harmful components such as hexavalent chromium and fluorine to the glass powder, which will also affect the environmental performance of glass inks.
