[0007] Although the bulk density of the above-mentioned architectural ceramics reaches 1.2-1.8 g / cm 3 and 1.96-2.33 g / cm 3 , but its water absorption rate reaches 5-9% and 10-22%, which is not safe and has a short service life, especially not suitable for dry hanging on external walls
[0008] In addition, the existing travertine and sandstone have poor frost resistance and do not meet the requirements for outdoor high-altitude curtain walls

Abstract

The invention discloses a light-weight high-strength ceramic plate. The light-weight high-strength ceramic plate is a light-weight ceramic plate which is fired at a firing temperature of 1050-1120 DEG C and has a honeycomb-like sealed pore internal structure, the volume weight is 1.55-2.1g/cm<3>, the thickness is 18-30mm, the water absorptivity is 0.1-0.5%, and the rupture modulus is no less than 20MPa.The light-weight high-strength ceramic plate is mainly prepared from the following raw materials: 1-3 parts of silicon carbide, 15-50 parts of ceramic waste solid, 10-35 parts of sludge or sediment, 10-35 parts of bentonite, 0.1-2 parts of green body enhancer and 0.1-3 parts of dispergator. Correspondingly, the invention also provides a preparation method of the light-weight high-strength ceramic plate. The light-weight high-strength ceramic plate has the advantages of light weight, high strength, low water absorptivity and high stone simulation degree, and can be dimensionally enlarged and thickened. When being used as an outdoor high-altitude curtain wall, the light-weight high-strength ceramic plate is very safe and convenient to construct, and the hanging cost is saved.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a lightweight high-strength ceramic plate and a preparation method thereof. Background technique [0002] In our country, ceramic products have been widely used in the interior and exterior wall decoration of buildings. The early buildings mostly used the wet paste process for the interior and exterior wall decoration construction of ceramic tiles. However, because the tiles that adopt the wet paste construction method are on the outer surface of the building, they are prone to aging, loosening and falling off under the effects of wind and rain erosion, earthquakes and temperature changes. In severe cases, it may cause a large amount of financial losses and casualties. [0003] With the development, experimentation and maturity of the ceramic panel curtain wall technology, the external wall dry-hanging ceramic panel curtain wall system, as the latest construction form of the building curt...
