preparation example Construction

[0061] A method for preparing a one-time fired multi-density composite foamed ceramic decorative plate includes the following steps S1-S8.

[0062] S1. Put the green body raw materials of the first and second foam layers into a ball mill according to the formula for ball milling. The ball milling process parameters of the green body raw materials of the first and second foaming layers are: fineness 1.8-2.0%, slurry moisture in weight percentage 35-40%, flow rate 55-65", and the qualified mud passes through 16 mesh and 100 mesh standard sieve.

[0063] 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.

[0064] 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 a...

Embodiment 1

[0083] Such as figure 1 As shown, the single-firing multi-density composite foamed ceramic decorative plate in this embodiment includes the first foam layer 1, the second foam layer 2, the sealing layer 3 and the surface decoration layer 4 arranged sequentially from bottom to top. The density of the second foam layer 2 is less than the density of the first foam layer 1, the first foam layer 1, the second foam layer 2, the sealing layer 3 and the surface decoration layer 4 are fired once, and the sealing layer 3 is used for sealing The surface of the second foam layer 2 has holes, the sealing layer 3 is a make-up soil layer, the surface decoration layer 4 is a glaze layer, and the surface decoration layer 4 includes a decoration layer 41 and a protective layer 42 . The thickness of the first foam layer 1 is twice that of the second foam layer 2 .

[0084] The base formula of the first foam layer 1 is shown in the following table in terms of weight percentage raw materials:

Embodiment 2

[0101] The once-firing multi-density composite foamed ceramic decorative plate of this embodiment includes a first foam layer, a second foam layer, a sealing layer and a surface decoration layer arranged in sequence from bottom to top, and the density of the second foam layer is less than The density of the first foam layer, the first foam layer, the second foam layer, the sealing layer and the surface decoration layer are fired once, the sealing layer is used to close the surface holes of the second foam layer, and the sealing layer is the makeup soil layer , the surface decoration layer is a glaze layer, and the surface decoration layer includes a decoration layer and a protection layer. The thickness of the first foam layer is 2.3 times that of the second foam layer.

[0102] The raw body formula of the first foam layer is shown in the following table in terms of weight percentage:

[0103]

[0104]

[0105] The raw body formula of the second foam layer is shown in t...

Abstract

The invention discloses a once-firing multi-density composite foamed ceramic decorative board. The once-firing multi-density composite foamed ceramic decorative board comprises a first foamed layer, asecond foamed layer, a sealing layer and a surface decorative layer arranged in order from bottom to top, wherein the density of the second foaming layer is less than the density of the first foaminglayer; the first foaming layer, the second foaming layer, the sealing layer and the surface decorative layer are fired once; the sealing layer is used for sealing a hole in the surface of the secondfoaming layer; the sealing layer is an engobe layer, or the sealing layer is a non-foamed ceramic slurry layer and an engobe layer, and the non-foamed ceramic slurry layer is located between the foamed layer and the engobe layer; the surface decorative layer is a glazed layer. Correspondingly, the invention also discloses a preparation method of the decorative board. The sealing layer can improvethe flatness of the product and improve the decorative effect of the product. The foamed ceramic decorative board is easy to clean. The foamed layers, the sealing layer and the surface decorative layer are fired once, and the layers are firmly bonded.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a once-fired multi-density composite 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 foame...
