High-performance ceramic rock plate and preparation method thereof

Abstract

The invention discloses a high-performance ceramic rock plate, which is prepared from the following raw materials in percentage by weight: 7.0 to 9.6 percent of talc, 5.7 to 7.7 percent of wollastonite, 0.01 to 0.05 percent of borocalcite, 0.04 to 0.2 percent of black mud, 0.06 to 0.3 percent of aluminum oxide, 27.9 to 30 percent of washing mud, 17.5 to 20 percent of lithium chinastone, 9.6 to 11 percent of albite and 24 to 32.19 percent of potassium feldspar. In addition, the invention further discloses a preparation method of the high-performance ceramic rock plate. Through formula design, a large number of layered anorthite crystals are separated out from a system, and the thermal expansion coefficient with a glass phase can be reduced by regulating and controlling the anorthite / quartz crystal phase proportion and increasing the anorthite content, so that internal stress formed in the cooling process is avoided, and the problems that a rock plate product is prone to cracking and edge breakage, high in splicing difficulty and the like are effectively solved; and the purpose of easy processing is achieved while good stability is achieved. The preparation method disclosed by the invention is based on a general traditional ceramic glaze and a ceramic production process, and has a promotion effect on technical progress and application development of the architectural ceramic industry.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a high-performance ceramic rock plate and a preparation method thereof. Background technique [0002] Slate is an explosive product in the building materials industry today, and it has many advantages that other building materials cannot match. The surface porosity of slate is almost negligible, which makes it have almost zero water absorption and permeability, which can meet the needs of water-rich areas and can easily wipe off surface stains. Due to high-temperature firing, the slabs are resistant to high temperatures and will not change color or deform, and will not release toxic substances, and there is no radiation. The safety can be guaranteed, and food can be placed and processed. Slate also has acid and alkali resistance, extremely high hardness and wear resistance, and is suitable for places with strict requirements such as tables, kitchens, and labor...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-performance ceramic slab. Through formula design, a large number of layered anorthite crystals are precipitated in the system to reduce the difference between the coefficient of thermal expansion and the glass phase, thereby Effectively solve the defects of rock slabs that are easy to crack and collapse, and achieve high toughness, strength and low expansion coefficient while having good stability
