Problems solved by technology

Glass-ceramic is also a kind of glass, and the Si-O content in its composition will not be less than that of ordinary inorganic glass, but why is there such a big difference? It can be understood that the traditional approach is to formulate hydrophobic and oil-repellent coating solutions for interfaces rich in Si-O structures. work effectively

[0174] The steps of the preparation method are the same as those in Example 1, and the differences are shown in Table 1, Table 2 and Table 3. That is to say, the specific composition of each raw material of the glass frit, the heat treatment process conditions of step (2) and the properties of the obtained glass-ceramic The test and step (3) ion exchange process conditions and the performance test results of the obtained strengthened glass-ceramic are shown in Table 1, Table 2 and Table 3 for details.

Abstract

The invention relates to microcrystalline glass with a hydrophobic and oleophobic composite coating on the surface as well as a preparation method and application of the microcrystalline glass, and the coated glass is microcrystalline glass or glass ceramic with a hydrophobic and oleophobic composite coating on the surface. The coated microcrystalline glass is characterized in that from the outermost surface of the glass, the microcrystalline glass comprises a hydrophobic and oleophobic layer, a middle layer, a priming layer and microcrystalline glass body or glass ceramic, the middle layer is formed by ionic crystals with the lattice energy of 700-3000kJ / mol, and the priming layer comprises a compound containing Si-O bonds or a mixed silicon oxide layer. According to the invention, a firm, durable and excellent-performance hydrophobic and oleophobic coating can be formed even if a coating interface of the microcrystalline glass has a few Si-O structures, and excellent hydrophobicity and oleophobicity can be generated no matter whether ion exchange is carried out on high-crystallinity glass or not.

Description

technical field [0001] The invention relates to a coated glass with water- and oil-repellent properties, a preparation method and application thereof, in particular to a glass-ceramic with a water- and oil-repellent composite coating on the surface of the high-crystallinity glass-ceramic. Background technique [0002] Generally speaking, the surface active energy of glass is relatively high, so the water and oil repellency is poor, which means that it is easier to adhere to dirt, and it is difficult to clean the surface after it is dirty. In many application scenarios, such as: stoves, range hood glass products, mobile phones, tablet computers, touch screen human-computer interaction windows, etc., people use a "hydrophobic" film on the glass surface to reduce the surface active energy of the glass. Improve its "water- and oil-repellent" ability and improve its hydrophobicity. After the hydrophobic ability is increased, the "slidability" can be clearly felt when the finger t...
