Abstract

The invention discloses an oil-stain-resistant ceramic sheet, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of mullite, 10 to 20 parts of cordierite, 5 to 10 parts of talcum powder, 4 to 6 parts of fiber-reinforced graphene, 2 to 6 parts of wollastonite hybrid modified alpha-aluminum oxide, 1 to 3 parts of silicon nitride composite nano powder and 1 to 5 parts of barium carbonate sintering aids. The oil-stain-resistant ceramic sheet is composed of mullite, cordierite, talcum powder and other raw materials, and the prepared product is resistant to oil stain and excellent in strength performance through the composite proportion of fiber-reinforced graphene, wollastonite hybrid modified alpha-aluminum oxide and silicon nitride composite nano powder.

Description

technical field [0001] The invention relates to the technical field of ceramic thin plates, in particular to an oil stain-resistant ceramic thin plate and a preparation method thereof. Background technique [0002] Ceramic thin plate (referred to as thin porcelain plate) is a plate-shaped ceramic product made of kaolin clay and other inorganic non-metallic materials, which are formed and calcined at a high temperature of 1200 degrees. Ceramic sheet is a plate-shaped ceramic product prepared by clay and other inorganic non-metallic materials through molding and high-temperature firing. The raw materials of ceramic thin plates usually contain minerals such as clay, quartz, feldspar, etc. After high-temperature firing, the green body forms a dense body mainly composed of glass phase, quartz and mullite. [0003] Most of the existing ceramic thin plates are sintered with inorganic materials, and the oil stain resistance of the thin plates is poor, which affects the use efficien...
