A brick adobe fired into a glass-ceramic composite board at one time

Abstract

The invention discloses a green brick of a one-step sintered glass-ceramic composite board. The green brick comprises a green body layer, a ground coat layer and a glass-ceramic frit layer from bottom to top and also comprises a fixing layer arranged on the surface of the glass-ceramic frit layer, wherein the fixing layer is formed by spraying a glass-ceramic frit particle fixing agent; and the glass-ceramic frit particle fixing agent comprises the following components in percentage by mass: 6.5-7.5% of nonionic polyurethane associative thickener, 3.2-4.4% of white carbon black, 1-1.5% of defoaming agent, 0.3-1.3% of dispersing agent and the balance of solvent. By using the green brick, glass-ceramic frit particles on the surface cannot be taken away by a draught fan at a preheating zone when being sintered, so that the waste is avoided, and the defect rate of glass-ceramic composite board products is reduced.

Description

technical field

[0001] The invention relates to the technical field of architectural ceramics, in particular to a brick adobe made of a glass-ceramic composite plate fired once. Background technique

[0002] Since the technology of glass-ceramic composite panel has been maturely applied, its technology has been continuously developed and innovated, and the product has become a high-grade decorative material in the market because of its transparent micro-crystalline frit particles and personalized decorative effect, and is well received by consumers. favorite.

[0003] The adobe of the glass-ceramic composite board fired at one time includes a green body layer, a bottom glaze layer and a glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The adobe is pressed, glazed and printed. Finally, a layer of glass-ceramic frit particles will be placed on the surface of the bottom glaze layer, and then sent to the kiln...
