Problems solved by technology

[0003] In order to meet the scratch resistance performance at high temperature, ceramic coatings are usually used to prepare coatings. Because ceramic coatings have high cross-linking density, fast response and good adhesion, they are mainly used as primers, but continuous coating on the outside of glassware When installing two layers of ceramic coatings of different colors, in order to prevent bleeding between the coatings, it is usually necessary to bake after spraying the primer, and then spray the topcoat on the primer. After the primer is baked, it is easy to cause the primer and The adhesion between the top coats becomes poor, which affects the performance of the coating

preparation example Construction

[0092] The preparation method of the scratch-resistant glass coating is as follows. First, sandblast the surface of the glass substrate, then spray the primer, bake at 120-150°C for 5-10 minutes, cool to 50-60°C, then spray the topcoat, and then bake at 280°C for 10 minutes. Finally cooled at room temperature.

[0093] When the ink layer is included in the scratch-resistant glass coating, the preparation method is as follows. First perform sandblasting treatment on the surface of the glass substrate, then screen print ink, bake at 60-80°C for 3-5 minutes, then spray primer on the ink, bake at 120-150°C for 5-10 minutes, After cooling to 50-60°C, spray topcoat, bake at 280°C for 10 minutes, and finally cool at room temperature.

Abstract

The invention relates to a scraping-resistant glass coating. The glass coating contains a base coat, a top coat arranged on the base coat, and an optional ink layer located under the base coat. The base coat contains silica sol-gel resin, toner, filler and optional silicone-modified polyester resin. Silica sol-gel resin of 100 weight parts is matched with 60-100 weight parts of toner, 10-15 weight parts of the filler and 0-150 weight parts of optional silicone-modified polyester resin; the top coat contains silica sol, organosilane, a catalyst, filler and toner. Silica sol of 100 weight parts is matched with 50-100 weight parts of organosilane, 0.3-1 weight part of the catalyst, 20-60 weight parts of the filler and 30-60 weight parts of toner; the ink layer contains silicone-modified polyester resin and toner. Silicone-modified polyester resin of 100 weight parts is matched with 50-70 weight parts of toner. The invention further relates to a preparing method for the coating and a coating combination used for preparing the coating.

Description

technical field [0001] The invention belongs to the field of glass coatings, in particular to scratch-resistant glass coatings. Background technique [0002] As the glass-making process has become more sophisticated, beautiful and durable glass products have been used more and more widely, especially kitchen items, such as glass bakeware used in ovens and other utensils. Glass products are usually transparent and have no color, and the appearance of glass products can be changed by coating. For the above-mentioned glassware, it can be observed from the inside of the vessel and from the outside of the vessel. If you want two-way observation to get different visual effects, you can apply two layers of colored coatings, such as coating the outside of the vessel first. Apply a layer of light color, and then apply a dark color on it, or vice versa, so that different visual effects can be obtained from the inside and outside of the vessel. At the same time, considering the use e...
