Problems solved by technology

[0005] However, in the process of tempering and sintering, on the one hand, the silver color material has slight oxidation phenomenon, and the chroma of the silver glaze layer is dark, which affects the decorative effect; some pollution
In addition, whether the silver decorative layer on the glass surface is prepared by the organic coating or the glass glaze layer process, its surface finish is very high, and the reflectivity is very high. Concave-convex sandstone effect on stone surface

preparation example Construction

[0026] The invention provides a method for preparing glass with a silver coating, which is characterized in that the preparation method comprises the following steps:

[0027] Step 1, preparation of glass surface modifier: weigh a certain amount of silica sol, aluminum sol and FeCl according to the formula ratio 3 solution, then pour it into the same container under the condition of 6000 rpm, stir at room temperature for 1-2 hours, then add boric acid powder, continue stirring, when the boric acid is completely dissolved, then add water glass, at 6000 rpm After stirring for 20-30 minutes under the condition of 10 minutes, stop stirring to obtain a mixed solution, and then put the mixed solution into an airtight container to obtain a glass surface modifier;

[0028] In step one, the formula of the glass surface modifier includes: water glass with a modulus of 2.8 at 10-15% by weight, silica sol with a solid content of 10% at 50-60% by weight, and 10% by weight. - 20% aluminum ...

Abstract

The invention discloses a preparation method of glass with a silver coating. The preparation method includes the following steps of 1, preparation of a modifier on the surface of the glass; 2, surfacemodification of the glass; 3, preparation of a cement base coating; 4, preparation of a cement coating. The method has the following advantages that by adopting mixed sol of Si(OH)4, Al(OH)3 and Fe(OH)3 for conducting surface modification on the glass, the bonding force between the cement coating and the glass is enhanced; by adopting a brushing method for combining a cement nursing and curing process, a silver inorganic gelatinized coating material can be prepared on the surface of the glass and firmly bonded to the glass, the structure of the coating material is porous and uneven, and a silver semigloss stone-like decoration effect can be achieved. A preparation process is simple, and the cost of the method is lower than that of a glass enamel layer process for preparing the silver glass; the silver coating is an inorganic material, has higher hardness than organic thin film materials and cannot be aged.

Description

【Technical field】 [0001] The invention relates to the technical field of preparation of building decoration materials, in particular to a method for preparing glass with a silver coating. 【Background technique】 [0002] Silver flat glass, because of its special metallic decorative effect, is widely used in partition materials and wall decoration panels for urban decoration. At present, there are two common processes for preparing silver flat glass: [0003] One is to use a special silver fluorocarbon resin glass paint to spray on the surface of the flat glass. After the paint is cured, a silver coating is formed on the surface. This method is simple in process and low in cost, but the coating on the glass surface is organic and has low hardness and aging resistance. Poor, it is easy to be scratched and peeled off during use, and the normal service life is no more than 10 years, and even less than 5 years under strong ultraviolet conditions. [0004] The other is to print a...
