Problems solved by technology

However, most of the existing rock slabs are 1200×1600mm in size 2 、2400×1800mm 2 、2400×1200mm 2 And other specifications, still unable to meet the requirements of large home decoration (cooktop, cabinet, bathroom cabinet, etc.)
On the other hand, the existing rock slab production system is immature, resulting in cracked bricks during drying and transportation, and the passing rate of drying is lower than 95%. Similarly, the passing rate of firing is also low, around 90%.
In addition, the existing ceramic rock slabs are extremely easy to break during processing. According to statistics, the cracking rate of the existing rock slabs has reached more than 65%, which has become a huge problem that plagues the industry.

preparation example Construction

[0046] see figure 1 , the invention provides a kind of preparation method of ceramic slate, which comprises the following steps:

[0047]S1: Mix various raw materials uniformly according to the formula, and ball-mill to obtain slurry;

[0048] Specifically, the formula is:

[0049] 15-20 parts of potassium feldspar, 8-15 parts of albite, 15-20 parts of calcined kaolin, 12-20 parts of black mud, 8-15 parts of white mud, 15-20 parts of pyrophyllite, 1-10 parts of toughening agent ; The sum of the parts by weight of the above raw materials is 100 parts.

[0050] Among them, potassium feldspar and albite are the main fluxes, which can promote sintering, obtain finished ceramic slate with water absorption <0.1%, improve the flexural strength of ceramic slate, reduce micropores, and improve stain resistance. Wherein, the consumption of potassium feldspar is 15-20 parts, and the consumption of albite is 8-15 parts; preferably, the consumption of potassium feldspar is 17-20 parts, ...

Embodiment 1

[0090] This embodiment provides a ceramic rock slab with a size of 3600×2000×20mm 3 ; Among them, the thickness of the green layer is 19mm;

[0091] The formulation of the green layer is:

[0092] 19 parts of potassium feldspar, 12 parts of albite, 16 parts of calcined kaolin, 18 parts of black mud, 10 parts of white mud, 18 parts of pyrophyllite, 1 part of low temperature toughening agent, 6 parts of high temperature toughening agent;

[0093] Among them, the particle size of 80% of the calcined kaolin is less than 1 μm; the low temperature toughening agent is methyl cellulose, and the high temperature toughening agent is mullite whisker;

[0094] Preparation method of ceramic slate:

[0095](1) Mixing various raw materials uniformly according to the formula, and ball milling to obtain slurry;

[0096] Among them, the 250-mesh sieve residue of the slurry is 0.2%;

[0097] (2) the slurry is spray-dried, and the first powder is obtained after sieving;

[0098] (3) passing ...

Embodiment 2

[0115] This embodiment provides a large-sized ceramic rock slab with a size of 3600×1800×25mm 3 ; Among them, the thickness of the green body layer is 24.5mm;

[0116] The formulation of the green layer is:

[0117] 19 parts of potassium feldspar, 12 parts of albite, 16 parts of calcined kaolin, 18 parts of black mud, 10 parts of white mud, 18 parts of pyrophyllite, 1 part of low temperature toughening agent, 6 parts of high temperature toughening agent;

[0118] Among them, the particle size of 90% of the calcined kaolin is less than 1 μm; the low temperature toughening agent is tobermorite, and the high temperature toughening agent is talc;

[0119] Preparation method of ceramic slate:

[0120] (1) Mixing various raw materials uniformly according to the formula, and ball milling to obtain slurry;

[0121] Among them, the 250-mesh sieve residue of the slurry is 0.4%;

[0122] (2) the slurry is spray-dried, and the first powder is obtained after sieving;

[0123] (3) pass...

Abstract

The invention discloses a preparation method of ceramic rock slabs, which comprises preparing slurry, spray drying to obtain powder, sieving part of the powder and mixing with the remaining powder to obtain powder for pressing, and pressing into a powder. , glazed for decoration, and then fired. The invention also discloses a ceramic rock slab prepared by adopting the above preparation method. The ceramic slate of the invention can be well adapted to the later deep processing technology, can be widely used in the fields of floors, curtain walls and veneers, and has the advantages of high strength, high hardness, acid and alkali resistance, high temperature resistance and the like.

Description

technical field [0001] The invention relates to the field of ceramic tiles, in particular to a preparation method of a ceramic slate and a ceramic slate. Background technique [0002] With the improvement of people's living standards, the selection of decoration and decoration materials has become more and more personalized, and more attention is paid to style and taste. The demand for applications in decoration is also increasing. The existing veneer materials mainly include natural stone and artificial quartz stone. Among them, artificial quartz stone refers to a plate formed by vibrating and pressing resin, quartz, and pigments and curing at 100-200 ° C. Because it contains resin materials, it has low hardness, poor acid and alkali resistance, and high temperature resistance. Although natural stone has relatively high hardness, good high temperature resistance and rich color, natural stone resources are extremely limited. [0003] In recent years, ceramic slabs have be...
