A kind of water-based bright environment-friendly tempered glass ink and preparation method thereof

Abstract

The invention belongs to waterborne highlight environment-friendly toughened glass ink and a preparation method thereof. The toughened glass ink is prepared from, by weight, 8-30 parts of inorganic pigments, 30-78 parts of a low-melting-point frit, 10-55 parts of ink abrasive oil, 0-2 parts of a wetting dispersant, 0-1 part of a defoamer, 0-2 parts of a flatting agent and a 0-2 parts of a solid additive. The glass ink is low in melting point, good in weather fastness, good in brightness and high in artistic appreciation; the low-melting-point frit is low in melting temperature and power saving, service life of the device can be effectively prolonged, and oxide is less volatile; the low-melting-pint frit does not contain Pb, Cr<6+>, Cd and Bi, cost of the ink can be effectively reduced, and harmful Pb, Cd and Cr<6+> are not contained; a Te element is introduced in the low-melting-point frit which can reduce the melting temperature, low-temperature viscosity of the frit is effectively reduced, and high covering power and anti-ultraviolet linear capacity of the glass are achieved.

Description

technical field [0001] The invention belongs to the field of chemical inks, and in particular relates to a water-based high-brightness environment-friendly tempered glass ink and a preparation method thereof. Background technique [0002] As we all know, glass tempered ink should have low sintering temperature, good weather resistance, excellent hiding power and good visual effect and other properties. However, traditional tempered inks contain lead and cadmium, or add a large amount of high-cost bismuth oxide. Oxide melting in traditional frits needs to be carried out at above 1200°C. Higher melting temperatures require more power consumption and greater damage to melting equipment, which greatly reduces its service life. At high temperature, oxides volatilize more, and many oxide vapors are poisonous, which will also cause greater damage to the health of operators. The present invention adopts 800°C-1000°C melting process, which is more low-carbon and environment-friendl...

Problems solved by technology

[0003] Traditional tempered glass inks are obtained by dissolving resins with varnishes such as xylene, cyclohexanone, and isophorone. This varnish contains a large amount of toxic and volatile solvents, which is harmful to people and the surrounding environment.
