Glassware coated with non-stick coating and its preparation process

Abstract

The invention discloses a glass vessel coated with a non-stick coating, which comprises a glass substrate, the glass substrate has an inner surface, the inner surface is coated with a non-stick coating, and the gap between the non-stick coating and the inner surface of the glass substrate is The transition is connected by an adhesive layer, wherein the non-stick coating includes a bottom layer and a surface layer; preferably, the glass substrate is made of high borosilicate glass. The invention also discloses a preparation process of the glassware coated with the non-stick coating, which includes pretreatment of the inner surface of the glassware, spraying of the adhesive layer, spraying of the bottom layer, spraying of the surface layer, and sintering to finally obtain the product. The glassware of the present invention avoids the sandblasting treatment on the glass surface but adopts the method of spraying a layer of bonding layer, the overall effect is improved, the non-stick coating has good bonding force with the substrate, and the surface of the vessel is non-stick, easy to clean, corrosion-resistant, High temperature resistance, long service life.

Description

technical field

[0001] The invention relates to the field of high borosilicate products, in particular to a glass vessel whose inner surface is coated with a non-stick coating and a preparation process thereof. Background technique

[0002] High borosilicate products are recognized as green and environmentally friendly glass. They are non-toxic, tasteless, and have no pollution to food. They can withstand high temperatures and can be used in ovens to make various Chinese and Western staple foods and pastries. Due to the advantages of high borosilicate glassware, It is being welcomed by many consumers day by day, and thus has entered thousands of households.

[0003] With the improvement of the quality of life, household ovens have gradually become popular in developed areas of the country and have entered the kitchens of many families. As a baking utensil for ovens, high borosilicate glassware is the choice of many home users because of its high temperature resistance and h...
