preparation example Construction

[0059] A method for preparing a one-time firing foamed ceramic decorative plate, comprising the following steps S1-S8.

[0060] S1. Put the green body raw material of the foaming layer into a ball mill according to the formula for ball milling. The ball milling process parameters of the green body raw material of the foam layer are: fineness 1.8-2.0%, slurry moisture in weight percentage 35-40%, flow rate 55-65", and the mud passes through 16 mesh and 100 mesh standard sieves after passing .

[0061] Fineness test method: 1 specific gravity cup with 325 mesh water washing, and the rest of the sieve is the fineness. The slurry flow rate was tested with a Tusi Viscometer.

[0062] Refer to the above ball milling process parameters to obtain a better uniformity of the slurry. The slurry passes through a 16-mesh and 100-mesh standard sieve, which can sieve out the oversized mud and fine powder, which is convenient for molding and improves the foaming of the green body during the...

Embodiment 1

[0081] like figure 1 As shown, the once-firing foamed ceramic decorative plate in this embodiment includes a foam layer 1, a sealing layer 2 and a surface decoration layer 3 arranged in sequence from bottom to top, and the foam layer 1, sealing layer 2 and surface decoration layer 3 For one firing, the sealing layer 2 is used to seal the surface holes of the foaming layer 1, the foaming layer 1 is a foamed ceramic with a single formula, the sealing layer 2 is a makeup soil layer, the surface decoration layer 3 is a glaze layer, and the surface decoration Layer 3 includes a decorative layer 31 and a protective layer 32 .

[0082] The base formula of foam layer 1 is shown in the following table in terms of weight percentage raw materials:

[0083] raw material Taishan moderate temperature sand Xinfengsha Warm sand in Mocun Sihui mud Sand in Teng County, Guangxi Dosage 11％ 9％ 5％ 18％ 10％ raw material Xinhuimu Guangsisha Liantang medium tem...

Embodiment 2

[0098] The once-fired foamed ceramic decorative plate in this embodiment includes a foam layer, a sealing layer and a surface decoration layer that are sequentially arranged from bottom to top. The foam layer, sealing layer and surface decoration layer are fired once, and the sealing layer is used The pores on the surface of the foaming layer are closed, the foaming layer is foamed ceramics with a single formula, the sealing layer is a makeup soil layer, the surface decoration layer is a glaze layer, and the surface decoration layer includes a decoration layer and a protection layer.

[0099] The base formula of the foamed layer is shown in the following table in terms of weight percent raw materials:

[0100] raw material Taishan moderate temperature sand Xinfengsha Warm sand in Mocun Sihui mud Sand in Teng County, Guangxi Dosage 10％ 10％ 4％ 19％ 9％ raw material Xinhuimu Guangsisha Liantang medium temperature sand Zhongshan sand Talc ...

Abstract

The invention discloses a one-time firing foamed ceramic decorative plate, which comprises a foaming layer, a sealing layer and a surface decoration layer which are sequentially arranged from bottom to top. It is used to close the pores on the surface of the foaming layer. The foaming layer is a foamed ceramic with a single formula, and the sealing layer is a make-up soil layer, or the sealing layer is a non-foaming ceramic base layer and a make-up soil layer, and the non-foaming ceramic base The layer is located between the foam layer and the make-up soil layer, and the surface decoration layer is a glaze layer. Correspondingly, the present invention also discloses a preparation method of the above-mentioned decorative plate, including ball milling, staling in a slurry tank; spraying granulation, staling in a silo; pressing into a green body and drying; applying a sealing layer; applying a surface decorative layer; firing. The sealing layer can improve the flatness of the product and enhance the decorative effect of the product. The foamed ceramic decorative plate of the present invention is easy to clean. The foam layer, the sealing layer and the surface decoration layer are fired at one time, and the bonding between the layers is firm.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a once-fired foamed ceramic decorative plate and a preparation method thereof. Background technique [0002] One-time fired foamed ceramics usually adopt a cloth press molding process, and the blank is pressed and molded, dried and directly fired in a kiln. Since the foamed ceramics will generate gas during the firing process, holes will be formed inside the green body to realize foaming. The generated gas will overflow the surface of the green body. Therefore, there are many pinholes on the surface of the fired product, which are easy to store and absorb dirt. [0003] Existing foamed ceramic decorative boards usually cut the fired foamed ceramics, and then set a decorative layer on the surface of the foamed ceramics to form a foamed ceramic decorative board. This decorative board is affected by the pores on the surface of the foamed ceramics. , The adhes...
