Abstract

The invention discloses a non-crackable rock slab and a preparation method thereof. The non-crackable rock slab is prepared from the following raw materials; 40-55 parts of wollastonite, 25-40 parts of mullite, 15-20 parts of potassium feldspar, 10-20 parts of flint clay, 6-12 parts of calcined hydrotalcite, 5-10 parts of high-alumina bauxite, 4-8 parts of modified silicon carbide, 2-6 parts of dolomite, 2-5 parts of magnesium oxide, 2-5 parts of strontium carbonate, 0.8-1.8 parts of far-infrared ceramic powder and 10-25 parts of reinforcing agent. The rock slab of the present invention has anexcellent modulus of rupture and extremely high breaking strength, so that the rock slab is not easy to be broken. The modulus of rupture and the breaking strength of the rock slab are significantlyimproved by adding modified silicon carbide and reinforcing agent to the formula of the rock slab.

Description

technical field [0001] The invention relates to the technical field of rock slabs, in particular to an unbreakable rock slab and a preparation method thereof. Background technique [0002] Ceramic rock slab, the English description is SINTERED STONE, which means sintered stone. It is made of natural raw materials through a special process, pressed by a press, combined with advanced production technology, and fired at a high temperature above 1100 ° C, which can withstand cutting , drilling, grinding and other processing processes of super-large specifications of new porcelain materials. [0003] Ceramic slabs are mainly used in the field of home and kitchen panels. At present, the existing slabs are easily damaged during use, transportation and installation, so it is necessary to increase the fracture modulus and failure strength of the slabs so that the slabs are not easily broken. Contents of the invention [0004] The invention provides a non-fragile rock plate and a ...
