Abstract

The invention discloses a high-temperature-resistant ink for microcrystal glass and a preparation method of the high-temperature-resistant ink. The ink consists of the following raw materials in partsby mass: 45-55 parts of an organic silicon resin, 25-35 parts of anatase titanium dioxide, 15-25 parts of barium sulfate, 0.2-1 part of a defoaming agent and 1-3 parts of a silane coupling agent withan epoxy group. The high-temperature-resistant ink disclosed by the invention adopts the organic silicon resin as a connecting material, the anatase titanium dioxide as a pigment and the barium sulfate as a filler, and under synergetic effects of the defoaming agent and the silane coupling agent with the epoxy group, the temperature resistance of the ink can be improved, the obtained high-temperature-resistant ink is capable of enduring a temperature up to 350 DEG C for 100 hours, and requirements of microcrystal glass of which the working temperature is 200-350 DEG C can be completely met. The ink disclosed by the invention has good printing adaptability when high-temperature-resistant properties are ensured, has good adherence to the microcrystal glass, has good flexibility and is not cracked on the microcrystal glass.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a high-temperature-resistant ink used for glass ceramics and a preparation method thereof. Background technique [0002] Glass-ceramic refers to the addition of some nucleating substances to the glass, and through heat treatment, light irradiation, or chemical treatment, a large number of tiny crystals are uniformly precipitated in the glass to form a multi-phase dense microcrystalline phase and glass phase. Complex. Crystalline glass (CRYSTOE and NEOPARIES) is also known as microcrystalline jade or ceramic glass. Crystallized glass looks very different from our common glass. It has the dual characteristics of glass and ceramics. The atomic arrangement inside ordinary glass is irregular, which is one of the reasons why glass is fragile. Glass-ceramics, like ceramics, is composed of crystals, that is to say, its atomic arrangement is regular. Therefore, glass-ceramics has higher b...
