Abstract

The invention discloses a non-fragile rock and a preparation method thereof, which are prepared from the following raw materials in parts by weight: 40-55 parts of wollastonite, 25-40 parts of mullite, 15-20 parts of potassium feldspar, 10-20 parts of Parts of burnt gemstone, 6-12 parts of sintered talc, 5-10 parts of high alumina, 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 far-infrared ceramic powder, 10~25 parts enhancer. The rock slab of the present invention has excellent modulus of rupture and extremely high failure strength, so that it is not easily broken; the modulus of rupture and the failure strength can be significantly improved by adding modified silicon carbide and a reinforcing agent into the formula of the rock slab.

Description

technical field [0001] The invention relates to the technical field of rock slabs, in particular to a non-fragile rock slab and a preparation method thereof. Background technique [0002] Ceramic slate, 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 large-scale new porcelain materials. [0003] Ceramic slate is mainly used in the field of home and kitchen board. At present, the existing rock slabs are easily damaged during use, transportation and installation, so it is necessary to improve the fracture modulus and failure strength of the rock slabs, so that the rock slabs are not easily broken. SUMMARY OF THE INVENTION [0004] The invention provides a non-fragile rock slab and a preparation method thereof. The roc...
