Embodiment 1

[0035] The present embodiment adopts following raw material and process to make ceramic sheet:

[0036] (1) Take each component with the following weight and set aside:

[0037] Clay particles 1000g; Surfactant and binder (one material with two functions): 88% hydrolyzed PVA, 200g; Water: 1500g; Plasticizer: propylene glycol, 300g; Additive: n-butanol, 100g.

[0038] (2) Prepare a mixture containing clay particles, surfactants, binders, additives and water, and form a layer of the mixture prepared in step S1 on the substrate by casting method; then, dry the mixture at 30°C to remove The water in the water forms a film layer;

[0039] (3) Peel off the film layer from the substrate, and according to the thickness requirements of the final product, laminate the film to form a layered structure, and hot press it at 10MPa to form a blank; finally, heat treat the blank at 1280°C for 2 hours to make it Sintered to make a thin ceramic plate for performance testing.

Embodiment 2

[0041] The present embodiment adopts following raw material and process to make ceramic sheet:

[0042] (1) Take each component with the following weight and set aside:

[0043] Clay particles 1000g; Surfactant and binder (one material with two functions): 88% hydrolyzed PVA, 500g; Water: 3000g; Plasticizer: propylene glycol, 300g; Additive: n-butanol, 100g.

[0044] (2) Prepare a mixture comprising clay particles, surfactants, binders, additives and water, and use a coating method to form a layer of the mixture prepared in step S1 on the substrate; then, dry and remove the mixture at 30°C The water in the water forms a film layer;

[0045] (3) Peel off the film layer from the substrate, and according to the thickness requirements of the final product, laminate the film to form a layered structure, and hot press it at 20MPa to form a blank; finally, heat treat the blank at 1280°C for 2 hours to make it Sintered to make a thin ceramic plate for performance testing.

Embodiment 3

[0047] The present embodiment adopts following raw material and process to make ceramic sheet:

[0048] (1) Take each component with the following weight and set aside:

[0049]Clay particles 1000g; surfactant: polysorbate 80, 310g; binder: polyacrylic acid, 300g; water: 1500g; plasticizer: propylene glycol, 300g; additives: n-butanol 100g + zirconium dioxide whiskers 10g.

[0050] (2) Prepare a mixture containing clay particles, surfactants, binders, additives and water, and form a layer of the mixture prepared in step S1 on the substrate by tape casting; then, dry naturally to remove the water, forming a film;

[0051] (3) Peel off the film layer from the substrate, and according to the thickness requirements of the final product, laminate the film to form a layered structure, and hot press it at 10MPa to form a blank; finally, heat treat the blank at 1280°C for 2 hours to make it Sintered to make a thin ceramic plate for performance testing.

Abstract

The invention discloses a preparation process of a ceramic sheet. According to the process, the ceramic blank film is firstly prepared, the influence of local defects on the performance of the ceramicsheet is reduced through a multi-layer overlapping process, the yield and the consistency of products are improved, and the reinforcing and toughening effects of additives such as whiskers can be fully exerted through cross overlapping in the overlapping process. The ceramic sheet prepared by the process is excellent in layered structure and low in water absorption rate, and the toughness of theceramic sheet is improved by 30-50% compared with that of a ceramic plate with the same thickness prepared by a traditional dry pressing method.

Description

technical field [0001] The invention relates to a preparation process of a thin ceramic plate, which belongs to the technical field of building decoration materials. Background technique [0002] Ceramic thin plate (referred to as thin porcelain plate or ceramic sheet) is a plate-shaped ceramic product made of kaolin clay and other inorganic non-metallic materials through forming, high-temperature calcination and other production processes. Under the condition of ensuring the function of the product, the thinning of the product is realized to the maximum extent, and the thickness of the product is less than 5.5mm; compared with similar products, the amount of building ceramic materials per unit area is more than doubled, saving more than 60% of raw material resources, reducing The comprehensive energy consumption is more than 50%, regardless of the amount of raw materials used or the energy consumption in the production process, the low-carbon goal of "material saving and en...
