Problems solved by technology

However, too high water content will lead to long drying time of the green body, deformation and cracking of the green body after drying, etc.
Foreign ceramic panels mainly use a large amount of aggregate and barren materials, but such a formula has high requirements for extrusion molding equipment and is not suitable for domestic conditions.
Some terracotta panels directly use the formula of bricks and tiles, or use the formula of general daily-use ceramics, which are difficult to apply to the production and requirements of terracotta panels.

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with specific examples.

[0016] The raw material composition of pottery plate is as shown in table 1, and in the embodiment 1-10 shown in table 1, plastic material powder content is generally at 35-55% (weight), if less than 30%, plastic material content is also little in the sintered body , the reinforcing effect of coarse aggregate is limited, and the mechanical properties of the fired body decrease. If it is greater than 55wt%, the amount of bentonite added will increase correspondingly, and the plasticity of the corresponding mud is too good. Although it is beneficial to extrusion, it is difficult to dry.

[0017] The best content of bentonite is 10-22%. If it is less than 10%, the corresponding mud material may not have good plasticity, which is not conducive to extrusion. If it exceeds 25%, the plasticity of the mud is too high, it is very difficult to dry, and cracking may occur eve...

Abstract

The invention relates to a ceramic plate for curtain wall decoration and a preparation method thereof. In the ceramic plate, a raw material formula comprises coarse ceramic aggregates and fine plastic materials, and ceramic slurry comprises the following components of bentonite, illitic soil, kaoline, pyrophyllite, quartz, feldspar, waste clinker, and water. The preparation method comprises the following steps of: uniformly mixing the ceramic raw materials according to a proportion of 45-65 wt% of aggregates and 35-55 wt% of plastic materials; then adding 12-16 wt% of water; shaping by using a spiral extruder; drying, and sintering at 1050-1350 DEG C in a raceway kiln. The obtained slurry has a favorable extrusion property, green bodies are easy to dry and sinter, and the ceramic plate has high strength, small contraction and difficult cracking.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a pottery plate used for curtain wall decoration and a preparation method thereof. Background technique [0002] Ceramic panels for architectural curtain wall decoration are made of natural pure clay as raw materials, and are manufactured through fine processing with various industrialized advanced equipment, with considerable strength, hardness and relatively precise geometric size and shape requirements. It is the application of traditional materials in modern architecture, and the ingenious combination of traditional materials, modern industrial technology and modern architecture. The installation of ceramic panels for architectural decoration adopts dry-hanging technology, so the materials are required to have excellent impact resistance and frost resistance. Its entire system is durable, solid and safe. At the same time, single-piece replacement can be realized in the case...
