Problems solved by technology

Although the bulk density of the above-mentioned architectural ceramics reaches 1.2-1.8 g / cm 3 and 1.96-2.33g / 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
[0007] Moreover, the existing travertine has poor frost resistance and does not meet the requirements for outdoor high-altitude curtain walls.

Abstract

The invention discloses high-strength and lightweight travertine. The travertine fired at the firing temperature of 1,050-1,120 DEG C and having a stereoscopic hole inside structure has the volume weight being 1.55-1.9 g / cm<3>, the thickness being 18-30 mm, the water absorption rate being 0.1%-1% and the modulus of rupture larger than or equal to 15 MPa. The high-strength and lightweight travertine comprises a surface material and a bottom material. Correspondingly, the invention further provides a preparation method of the high-strength and lightweight travertine. The high-strength and lightweight travertine is light in weight, high in strength and low in adsorption rate, has high stone simulation degree, can be made to be larger and thicker in size and is very safe and convenient to construct when used for high-altitude outdoor curtainwalls, 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 travertine 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 curtain wall technology, the external wall dry-hanging ceramic curtain wall system, as the latest construction form of the architectural curtain wall, ...
