Abstract

The invention discloses a preparation method of a mineral particle reinforced thermal insulation ceramic sheet, and the method comprises the following steps: step 1, mixing fly ash, diatomite, paraffin and water to obtain a dispersion system; step 2, stirring wollastonite, alumina microspheres, zirconia microspheres, magnesium carbonate, attapulgite, sodium silicate and zeolite in a nitrogen protective atmosphere for 40-60 minutes to obtain a mixed system; step 3, carrying out ball milling on the mixed system for 2-4 hours, and drying; step 4, sintering the dried system for 4-6 hours at the temperature of 900-1200 DEG C, molding, cutting, and naturally cooling to room temperature to obtain a thin plate base material; step 5, spraying the dispersion system onto a thin plate base material, and standing and curing; and step 6, sintering the base material subjected to standing and curing at 800-1200 DEG C in a nitrogen protective atmosphere, cooling to room temperature, and polishing to obtain the mineral particle reinforced thermal insulation ceramic sheet.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to a preparation method of a mineral particle-reinforced thermal insulation ceramic thin plate. Background technique [0002] Ceramic materials refer to a class of natural or synthetic inorganic non-metallic materials, which are mainly formed by molding and sintering raw materials at high temperatures. There are many types of ceramic products, and they are easy to maintain and decorative. However, the application of most ceramic materials is limited due to insufficient strength, poor toughness and single performance. [0003] At present, there are many insulation materials in my country, mainly including hard silicate materials, foam plastic materials and other cotton and linen fabric materials. Among these materials, foam plastic materials and cotton and linen fabric materials are mainly used in residents' lives, and are not suitable for the production proce...
