A glass-ceramic facing lightweight ceramic composite brick and its preparation method

Abstract

The invention discloses a glass-ceramic decoration face light ceramic composite brick and a preparation method thereof. The glass-ceramic decoration face light ceramic composite brick comprises a heat-preserving base layer and a decorating wear-resisting layer arranged on the heat-preserving base layer. The heat-preserving base layer is a blind hole foaming ceramic layer, the thickness ranges from 4 mm to 60 mm, and the volume density ranges from 230 Kg / m<3> to 980 Kg / m <3>; the decorating wear-resisting layer is a glass-ceramic layer, the thickness ranges from 2 mm to 4 mm, and the volume density ranges from 2000 Kg / m<3> to 3000 Kg / m <3>; a bottom material of the heat-preserving base layer and a face material of the decorating wear-resisting layer are formed by secondary material distribution and one-time formation through a pressing machine and one-time firing through a roller kiln. The base layer of the composite brick has the heat-preserving, heat-insulating and sound-insulating performance, the decorating glass-ceramic layer has the wear-resisting property, the anti-skid property, shock resistance and the like, is excellent in decoration performance, and can be widely applied to heat-preserving decoration of external wall lower layers, indoor wall faces and indoor grounds, while existing heat-preserving materials and decoration materials do not have the properties and the application; solid waste generated by exploiting and processing perlite is adopted, the production process saves energy and is environmentally friendly, and sustainable development of perlite industries can be promoted.

Description

technical field [0001] The invention relates to the field of light-weight ceramic bricks, in particular to light-weight ceramic composite bricks with a glass-ceramic finish and a preparation method thereof, which can be applied to the decoration and heat preservation of the lower floors of exterior walls, interior walls and interior floors. Background technique [0002] China's building materials industry standard JC / T1095-2009 points out that light-weight ceramic tiles are low-density ceramic tiles prepared from ceramic raw materials or industrial waste as the main raw material through forming, high-temperature firing and other production processes (among them, the bulk density is not greater than 1.50g / cm³ ). [0003] There are mainly two types of existing lightweight ceramic tile products, one is full-body bricks, and the other is composite bricks. The material of the whole body brick is uniform, and the surface is decorated by carving; the surface of the composite brick...

AI Technical Summary

Problems solved by technology

The disadvantage of this technical solution is that the thickness of the base layer is difficult to distribute, and deformation will occur if the thickness exceeds 1mm. The thickness of the sprayed glaze layer cannot exceed 2mm, and it cannot protect the foam layer, which limits the application field.

Although the wear resistance of microporous foamed microcrystalline glaze is better than that of foamed glass or foamed ceramics, the wear resistance is greatly reduced due to the existence of micropores, and it still cannot meet the decorative and thermal insulation requirements of low-rise exterior walls, interior walls and interior floors. At the same time, the firing process of kiln furniture, dry-scattered materials, and tunnel kiln (or shuttle kiln) is used, the product yield is low, the stability is not high, and the consumption of kiln furniture and kiln cars is also large
