preparation example Construction

[0066] A method for preparing a single-firing multi-density composite foam whole-body decorative board, comprising the following steps S1-S7:

[0067]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 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 .

[0068] 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.

[0069] 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 th...

Embodiment 1

[0084] Such as figure 1 As shown, the single-firing multi-density composite foam whole-body decorative board of this embodiment includes a first foam layer 1, a second foam layer 2, and a surface hole for sealing the second foam layer 2 arranged in sequence from bottom to top. The sealing layer 3, the density of the second foaming layer 2 is less than the first foaming layer 1, and the formula of the first foaming layer 1, the second foaming layer 2 and the sealing layer 3 all contains colorant, and the sealing layer 3 is Make-up soil layers. The thickness of the second foam layer 2 is 1.5 times that of the first foam layer 1 .

[0085] The green body formula of the first foam layer 1 includes a green body basic formula and a green body colorant, and the weight ratio of the green body colorant to the green body basic formula is 10:100, and the basic formula raw materials in weight percentage are shown in the following table :

Embodiment 2

[0101] The single-firing multi-density composite foam whole-body decorative board of this embodiment includes a first foam layer, a second foam layer, and a sealing layer for sealing the surface holes of the second foam layer arranged in sequence from bottom to top. The density of the foaming layer is smaller than that of the first foaming layer, and the formulations of the first foaming layer, the second foaming layer and the sealing layer all contain pigments, and the sealing layer is a make-up soil layer. The thickness of the first foam layer is 2.5 times that of the second foam layer.

[0102] The green body formula of the first foaming layer includes a green body basic formula and a green body colorant, and the weight ratio of the green body colorant to the green body basic formula is 5:100, and the basic formula raw materials in weight percentage are shown in the following table:

Abstract

The invention discloses a one-time fired multi-density composite foam whole-body decorative board, which comprises a first foam layer, a second foam layer and a sealing layer for sealing holes on the surface of the second foam layer which are sequentially arranged from bottom to top , the density of the second foam layer is less than the density of the first foam layer, and the formulas of the first foam layer, the second foam layer and the sealing layer all contain colorants, and the sealing layer is a make-up soil layer, or the sealing layer is The non-foaming ceramic base layer and the makeup soil layer, the non-foaming ceramic base layer is located between the second foaming layer and the makeup soil layer. Correspondingly, the present invention also discloses a method for preparing the above-mentioned decorative board, which includes ball milling the green body raw material of the foaming layer, staleing the slurry tank, spraying granulation, aging the silo, pressing it into a green body, drying, and applying makeup soil, or Apply the non-foaming ceramic slurry and make-up clay. The decorative plate of the present invention is a decorative plate with a whole body color, and has the characteristics of easy cleaning, high surface smoothness and suitable product density.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a one-time fired multi-density composite foamed whole-body 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 th...
