Problems solved by technology

The existing antique brick slabs have made some progress in appearance, color, hardness, water absorption, wear resistance and other aspects; but the improvement of performance has led to an increase in the production cost of antique bricks; at the same time, the existing antique bricks In the preparation process of rock slabs, the preparation method is complicated, and the concave-convex feeling of the preparation is uncontrollable, and the concave-convex feeling cannot be designed according to the user's needs. Generally, when the brick body has a concave-convex structure, the brick body is not easy to have gloss. That is, the two requirements of bumpiness and gloss cannot be met at the same time
[0003] Moreover, the existing antique brick and rock slab products have a single effect and serious homogeneity, which causes aesthetic fatigue to users

Embodiment 1

[0040] The dewdrop dry granules, applied on the surface of the slate, include the following components by weight:

[0041] 35~40 parts of nepheline syenite, 8-12 parts of burnt talc, 8-15 parts of calcite, 15-20 parts of zircon, 10-15 parts of quartz, 0-6 parts of barium carbonate, 2-5 parts of calcined alumina , 4-8 parts of air knife soil and 1-5 parts of zinc oxide;

[0042] The chemical composition percentages of dewdrop dry granules are as follows:

[0043] ZrO 2 :3-5%, SiO 2 :55-64%, Al 2 o 3 :8-12%, CaO:10-15%, MgO:3-6%, ZnO:1-5%, BaO:0-6%, K 2 O:3-4%, Na 2 O:3-5%, Fe 2 o 3 : 0-0.1%, B 2 o 3 : 2-5%, loss on ignition 3-5%.

[0044] Nepheline syenite is a solid solution of feldspar and nepheline. The zircon is a silicate mineral, and zircon is widely found in acidic igneous rocks and also in metamorphic rocks and other sediments. Zircon is chemically stable, so gem-quality zircon can also be seen in river gravel. There are many kinds of zircons, and differen...

Embodiment 2

[0052] The difference with embodiment 1 is that the dewdrop dry granules are selected as follows:

[0053] 35-38 parts of nepheline syenite, 10-12 parts of burnt talc, 8-10 parts of calcite, 15-17 parts of zircon, 10-12 parts of quartz, 1-2 parts of barium carbonate, 2-3 parts of calcined alumina , 4-5 parts of air knife soil and 1-3 parts of zinc oxide;

[0054] The chemical composition percentages of dewdrop dry granules are as follows:

[0055] ZrO 2 :4-5%, SiO 2 :58-62%, Al 2 o 3 :8-10%, CaO:10-12%, MgO:3-4%, ZnO:3-5%, BaO:2-3%, K 2 O:3-4%, Na 2 O:3-5%, Fe 2 o 3 : 0-0.1%, B 2 o 3 : 2-5%, loss on ignition 3-5%.

[0056] The dewdrop dry crystals in this example belong to the tetragonal crystal system, the crystals are square short columnar, square biconical, high hardness, diamond luster, high refractive index, strong gloss, high birefringence, high density, high dispersion and typical spectral features, etc.

[0057] Tested by a gloss meter model WGG60-E4, the ...

Embodiment 3

[0059] A dewdrop effect glaze ink,

[0060] Dewdrop effect glaze ink, including the following raw materials by weight:

[0061] Dewdrop dry granule glaze powder 35-55 parts, functional resin 4-8 parts, dispersant 25-45 parts, surfactant 2-4 parts, defoamer 0.2-0.5 parts, suspending agent 0.05-0.12 parts;

[0062] The dewdrop dry glaze powder comprises the following components by weight:

[0063] 35-38 parts of nepheline syenite, 10-12 parts of burnt talc, 8-10 parts of calcite, 15-17 parts of zircon, 10-12 parts of quartz, 1-2 parts of barium carbonate, 2-3 parts of calcined alumina , 4-5 parts of air knife soil and 1-3 parts of zinc oxide.

[0064] The functional resin is a mixture of carboxymethyl cellulose and acrylic resin, and the mass mixing ratio of carboxymethyl cellulose and acrylic resin is 1:1-5.

[0065] The dispersant is polymer polyacrylate emulsion.

[0066] The antifoaming agent is at least one of mineral oil and organic silicon; the suspending agent is cas...

Abstract

The invention relates to the application field of slate, and discloses dewdrop dry particles, dewdrop effect glaze ink and a preparation method, slate and a preparation method. Dried dewdrops, applied on the surface of rock slabs, include the following components by weight: 35-40 parts of nepheline syenite, 8-12 parts of burnt talc, 8-15 parts of calcite, 15-20 parts of zircon, 10 parts ‑15 parts of quartz, 0‑6 parts of barium carbonate, 2‑5 parts of calcined alumina, 4‑8 parts of air knife soil and 1‑5 parts of zinc oxide; the invention realizes the application by setting dewdrop dry particles and dewdrop effect glaze ink It has a high-gloss water drop effect when placed on a rock plate, has high transparency, high temperature resistance, and wear resistance, and has a good surface unevenness, and the gloss can reach more than 80 degrees; by introducing nepheline syenite and adjusting SiO 2 and Al 2 o 3 The ingredients ensure the crystal clear effect of dewdrop dry particles, while maintaining the effect of dewdrop particles, lowering the firing temperature, increasing the firing range, and making the firing range reach 1120-1200°C, which is conducive to firing.
