Problems solved by technology

Among them, large slate boards can be used in cabinet countertops, panels, dining tables, coffee tables and other areas. Compared with traditional wood products, the cost is lower and the life is longer. It provides a new choice for modern architectural decoration. Currently, slate boards on the market Most of the products are mainly polished and polished. With the promotion of rock slabs, the single effect of the product will inevitably cause consumers' aesthetic fatigue, and the rock slabs with natural concave-convex texture are close to the time imprinted effect left by the original marble after many years. , in line with the individual aesthetics of modern people, the market demand is getting higher and higher, but this type of product is usually of poor quality, and the general product surface flatness is not good, which leads to poor stain resistance of the product, which is difficult to meet the requirements of modern high-end decoration need

preparation example Construction

[0043] One embodiment of the present invention provides a method for preparing rock slabs, comprising the following steps:

[0044] S101: preparing a green body.

[0045] It can be understood that existing methods can be used to prepare green bodies, preferably step S101 includes the following steps:

[0046] S1011: Obtain powder;

[0047] In some embodiments, the moisture content of the powder in step S1011 is 6.5%-7.0%. In some embodiments, the moisture content of the green body is controlled at 6.5%, 6.6%, 6.7%, 6.8%, 6.9% or 7%, so as to facilitate the formation of a dense green body, facilitate the subsequent steps, and improve the quality of the green body. The strength of the body meets the strength requirements of rock slabs.

[0048] In some embodiments, by mass percentage, the chemical composition of the powder includes: SiO 2 60%-64%, Al 2 o 3 22%-26%, TiO 2 +Fe 2 o 3 0.2%-0.6%, MgO 1%-2%, CaO 0.5%-1.2%, K 2 O 1.5%-2.5%, Na 2 O 2.5%-3.5%; further, the c...

Embodiment 1

[0107] Raw materials for preparing dry beads: 38 parts of potassium feldspar, 8 parts of albite, 8 parts of kaolin, 14 parts of barium carbonate, 6 parts of wollastonite, 4 parts of zinc oxide, 6 parts of strontium carbonate, 11 parts of calcite, quartz 2 parts, 3 parts of alumina;

[0108] (1) Preparation of dry ball beads: Precisely mix the above raw materials and mix them evenly, then put the mixture into a frit furnace for firing, the temperature curve is: heating to 300°C for 10 minutes, and then heating for 30 minutes to 1100°C, then heated to 1450°C for 20 minutes, and then kept at 1450°C for 10 minutes. The above-mentioned materials are melted under this temperature curve, and then flow into the cold water tank through the discharge port for quenching to obtain the semi-finished product of dry ball bead, crush the semi-finished product of dry bead, and control the particle gradation between 250 mesh and 300 mesh ;Spray the dry beads obtained after crushing into the ve...

Embodiment 2

[0118] Raw materials for preparing dry beads: 30 parts of potassium feldspar, 10 parts of albite, 10 parts of kaolin, 13 parts of barium carbonate, 7 parts of wollastonite, 5 parts of zinc oxide, 7 parts of strontium carbonate, 12 parts of calcite, quartz 3 parts, 3 parts of alumina;

[0119] The preparation method is the same as in Example 1, and the difference is that the glaze and water-based glaze are different in (5) and (6), specifically:

[0120] Peel-off glaze: including 40% of peel-off base glaze, 45% of ethyl acetate flux, and 15% of additives. The peel-off base glaze is prepared from the following raw materials: 7 parts of calcined kaolin, 26 parts of potassium feldspar, sodium feldspar 18 parts of limestone, 8 parts of wollastonite, 4 parts of barium carbonate, 5 parts of zinc oxide and 33 parts of frit; by mass percentage, the chemical composition of frit includes: SiO 2 55.5%, Al 2 o 3 19%, CaO 4.5%, MgO 2.8%, K 2 O 4.6%, Na 2 O 4.7%, BaO 2% and ZnO 2.8%, ...

Abstract

The invention relates to a rock plate and a preparation method thereof. The preparation method comprises the following steps: preparing a green body; forming a cover glaze layer on the green body; forming a pattern layer on the cover glaze layer; sequentially applying stripping glaze containing a hydrophobic solvent and water-based glaze containing water on the pattern layer to form a grain layer; and forming a dry bead particle layer on the grain layer, wherein dry bead particles in the dry bead particle layer are spherical and are mainly prepared from the following raw materials in parts by weight: 30-45 parts of potassium feldspar, 6-10 parts of albite, 6-10 parts of kaolin, 10-20 parts of barium carbonate, 4-8 parts of wollastonite, 3-6 parts of zinc oxide, 4-8 parts of strontium carbonate, 7-13 parts of calcite, 1-4 parts of quartz and 1-5 parts of aluminum oxide. The rock plate prepared by the preparation method not only has better matte gloss, but also has concave-convex textures along lines on the surface; and the rock plate is combined with matte dry round bead particles for application, so high flatness, fine, smooth and mild hand feeling and good quality are achieved, and the application range of the rock plate can be widened.

Description
