TECHNICAL FIELD

[0032] According to the preparation process of the glass-ceramic stacked ceramic product, the following steps are included:

[0033] Step a, preparing a glass module and a biscuit module;

[0034] Step b, stacking the glass module and the biscuit module to obtain a green body;

[0035] Step c, applying glaze on the surface of the green body;

[0036] Step d, glazing in the kiln. Glazing temperature is 1100-1150 degrees Celsius. Because the melting temperature of the glass module is high, the deformation of the glass module is less at this glazing temperature. After glazing, the glass module and the biscuit module form an integral whole, and the glaze is covered on the surface.

[0037] In step a, the glass module preparation process is as follows: 1. Prepare raw materials: prepare and mix the raw materials in proportion; 2. Put the raw material mixture into the melting furnace for high-temperature melting, the melting temperature is 1600 degrees Celsius, and the melting time is 8-10 hours; 3. Glass forming: pour the melted raw materials into the mold for forming, the ejection temperature is 500-600 degrees Celsius, use annealing equipment for cooling, the annealing equipment is a conveyor belt with a closed cover, the initial stage temperature of the conveyor belt is consistent with the ejection temperature, and the end temperature is 60 degrees Celsius, the annealing time is 6-8 hours, and finally the glass module is obtained; the preparation process of the biscuit module is as follows: after the blank forming, the biscuit module is prepared by baking in the kiln. The initial stage temperature of the conveyor belt is consistent with the ejection temperature, and the glass module is not easy to crack through slow annealing.

[0038] In step a, one or both of the inner and outer surfaces of the glass module are treated, which is mist treatment and / or waxing treatment; the surface treatment can be mist treatment or waxing treatment, the inner and outer surfaces can be treated by the same surface treatment process or different surface treatment processes, or both surface treatment processes are carried out at the same time. Different process combinations make the glass module have different effects. For example: when the inner and outer surfaces of the glass module are mist treated at the same time, after subsequent glazing, the inner and outer surfaces are glazed at the same time, and after glazing, the glass and the inner and outer glaze surfaces are combined; when the inner and outer surfaces of the glass module are waxed at the same time, after subsequent glazing, the inner and outer surfaces are not glazed at the same time, and after glazing, the glass is in its original color and has glaze vertical lines; when one surface of the glass module is waxed and the other surface is mist treated, after subsequent glazing, one surface is covered with glaze and the other surface is not glazed, and after glazing, the glass and the glaze are combined, and one surface has glaze vertical lines; the same surface can be mist treated first and then waxed, and after subsequent glazing, the surface of the glass module is not glazed, but during the firing stage, the glaze forms vertical lines on its surface. Because the glass surface is mist treated, the glaze flows slowly, the vertical lines are limited to the upper half of the glass module, and the glass module presents a mist effect and has glaze flow lines.

[0039] The step of the frosting treatment includes: sandblasting the surface of the glass module, and then etching the surface by using an etching liquid to form a frosted surface; the surface of the glass module after the frosting treatment is rough, so that the face glaze can be hung on the surface of the glass module in the subsequent glazing process, and the face glaze and the glass module form a unique glaze effect after being combined; when different glazes are applied to the inner and outer surfaces of the glass module, the light and shadow formed by the interlaced lines of different colors after the glass module transmits light have unique beauty.

[0040] The step of the waxing treatment includes: cleaning the surface of the glass module, and then waxing the surface to form a wax layer; the wax layer on the surface of the glass module is completely decomposed in the subsequent drying and firing stages; the surface of the glass module after the waxing treatment cannot be glazed in the glazing process, so the surface is not covered with glaze; after firing, the surface mainly presents the natural color of the glass; however, due to the fluidity of the glaze, the glaze of the fired module flows downward to the surface of the glass during the glazing process, so the surface of the glass has the vertical lines formed when the glaze of the upper fired module flows, and the surface of the glass presents the vertical lines with the same color as the glaze and a concave-convex texture after firing.

[0041] In step b, the glass module and the fired module are connected by using a buffer bonding material at the connecting position. The buffer bonding material is applied to the connecting position of the fired module to connect the glass module and the fired module; the buffer bonding material contains a large amount of organic matter, has high porosity after firing, and has low elastic modulus, large elastic deformation capacity, and good elasticity; when the buffer bonding material is used as the connecting material of the glass module and the fired module, it can absorb the deformation of the two modules and improve the adaptability of the two modules.

[0042] The above are only some specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application using this concept shall be regarded as an infringement of the protection scope of the present application.
