Problems solved by technology

Although certain achievements have been made, the recycling rate of polishing slag in ceramic production is still small. At present, more than 90% of polishing slag is disposed of in landfill, and only less than 10% is recycled.

Abstract

The invention provides a manufacturing method of a ceramic thermal insulation wall material, and relates to the field of construction materials. The manufacturing method comprises following steps: mixing ceramic polishing slag, bentonite, glass fibers, limestone, and expanded perlite, grinding the mixture into powder, drying, adding fly ash, water, sodium terephthalate, and carboxymethyl cellulosesodium into dry powder, evenly stirring, filling the mixture into a mould, pressing, moulding to obtain a blank; wrapping a plastic film on the surface of the blank, placing the blank in an ultrasonic wave generator, carrying out an ultrasonic treatment, drying the blank in a drying box until the weight is constant; heating and sintering the dried blank in an electric furnace, taking out the blank, and curing the blank for 10 to 20 d to obtain the ceramic thermal insulation wall material. The technology is simple, the wastes are converted into valuable resources, and the manufactured ceramicthermal insulation wall material has the advantages of high strength, low density, and good thermal insulation and soundproof effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for manufacturing a ceramic thermal insulation wall material. Background technique [0002] At present, the most widely used wall materials are mainly divided into external insulation wall system, internal insulation wall system and self-insulation wall system according to the different insulation layer materials. At present, clay bricks, clay hollow bricks, cement mortar lattice bricks, aerated concrete blocks, etc. are mainly used as wall materials. Due to the heavy weight, high water absorption rate and high thermal conductivity of the above materials, the building has heavy load bearing, poor thermal insulation performance and low earthquake resistance. Poor, does not meet the performance requirements of modern building materials for shock resistance, heat preservation, and energy saving. [0003] With the rapid growth of the economy and construction industry, my c...
