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

[0057] Correspondingly, refer to figure 2 , the present invention also discloses a method for preparing the above-mentioned large-scale ceramic rock slab, which includes the following steps:

[0058] S1: Mix various raw materials evenly according to the formula, and ball mill to obtain slurry;

[0059] Specifically, the formula is: 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 the toughening agent; the sum of the parts by weight of the above raw materials is 100 parts. The above formula can be better applied to the existing production line, reduce drying breakage, breakage during transportation and firing breakage, and increase the yield of finished products. At the same time, this formula can also ensure that the deformation is relatively uniform during the drying and firing process, and the passing rate of drying and firing can be improv...

Embodiment 1

[0080] This embodiment provides a large-scale ceramic slab, its size is 3600 × 2000 × 20mm 3 ; Wherein, the thickness of green body layer is 19mm;

[0081] The formula of green body layer is:

[0082] 19 parts of potassium feldspar, 12 parts of albite feldspar, 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, and 6 parts of high-temperature toughening agent;

[0083] Among them, 80% of the particles in the calcined kaolin have a particle size of less than 1 μm; methyl cellulose is used as the low-temperature toughening agent, and mullite whiskers are used as the high-temperature toughening agent;

Abstract

The invention discloses a large-size ceramic rock plate which has a surface area of 3-12m<2> and a thickness of 12-30mm. The large-size ceramic rock plate comprises a green body layer, a ground coat layer, a pattern layer and a cover coat layer; wherein the thickness of the green body layer is 11.5-29.5mm; the green body layer is mainly prepared from the following raw materials by weight: 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 and 1-10 parts of a toughening agent; wherein the sum of the weight parts of the raw materials is 100 parts. The ceramic rock plate can well adapt to a later deep processing technology, can be widely applied to the fields of floors, curtainwalls 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 large-scale ceramic rock plate and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the choice of decoration and decoration materials, the aesthetics are becoming more and more individualized, and more attention is paid to style and taste. For walls, floors, curtain walls, furniture, cabinets, countertops and other decorative materials in modern times There are more and more application requirements in decoration. Existing facing materials mainly contain natural stone and artificial quartz stone. Among them, artificial quartz stone refers to a plate formed by vibrating resin, quartz, and coloring materials 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 te...
