Problems solved by technology

On the one hand, the existing lightweight ceramic plates and their production technologies have high firing temperatures, basically above 1100°C, and some even reach 1600°C, and the firing cycle is long.
On the other hand, the utilization rate of existing pearl industrial waste is low, and the patent CN102603356A can only use perlite micropowder, and the utilization of expanded perlite is still blank

Abstract

The invention discloses a thermal insulating decorative ceramic plate produced by comprehensive utilization of perlite waste and a production method thereof. A matrix formula consists of: 25%-100% of perlite micropowder, 20%-80% of expanded perlite micropowder, 2%-25% of Guangdong black mud, 0%-10% of limestone, 0.1%-5% of fluorite, 0.1%-2% of black silicon carbide, 0.5%-15% of bentonite, 0.1%-5% of sodium metasilicate nonahydrate, 0.1%-0.5% of sodium humate, and 0.1%-1.0% of sodium tripolyphosphate. A glaze formula consists of: 50-90% of expanded perlite powder, 50-90% of low temperature frit, 0.1-5% of zinc oxide, 0.1-5% of fluorite, 0-5% of apatite, 0.1-2.0% of sodium tripolyphosphate, 0.5-5% of kaolin, and 0.1-0.5% of sodium methyl cellulose. The production method is characterized by naked firing in a roller kiln at a low temperature of 900DEG C-1050DEG C. After firing, the thermal insulating decorative ceramic plate with a water absorption rate of less than 0.5%, a volume density of less than 500kg/m<3>, a rupture modulus of greater than 3.5Mpa, a thermal conductivity coefficient of less than 0.08/W/(m.k), and a combustion level of A can be obtained.

Description

technical field [0001] The invention relates to the field of thermal insulation building materials, in particular to a light-weight thermal insulation decorative ceramic plate produced by using the solid waste in the production and processing process of expanded perlite-perlite micropowder and expanded perlite micropowder and a production method thereof. Background technique [0002] Chinese patent CN1800082A provides a production method of shale thermal insulation ceramic facing bricks. The technical feature is that shale ore particles and fly ash are used as the main raw materials to press into blanks, and the surface of the bricks is coated with clay glaze and calcined at a high temperature of 1600 ° C. product. There are no more detailed product technical characteristics such as thermal conductivity, thickness, and bulk density in the manual, so its thermal insulation performance cannot be determined. [0003] Chinese patent CN201137265Y provides a thermal insulation ce...
