Abstract

The invention discloses a glazed ceramic decorative wall tile. The wall tile comprises a ceramic tile body and a glaze surface, wherein the ceramic tile body comprises 15-80% of ceramic factory wastepressed mud, 5-75% of rotten ceramic tile powder or stone powder tailings, 1-10% of coal water slurry slag, 0-20% of foamed ceramic recycled waste, 0-12% of talc, 5-20% of clay, 2-15% of bentonite and0.3-1.5% of a foaming agent; and the glaze surface comprises an isolation glaze located on the surface of the ceramic tile body, a surface glaze located on the isolation glaze and a protective glazelocated on the surface glaze. Solid waste in the ceramic industry is used as main raw materials, and the wall tile and the method conform to the trend of environmental protection, greenness and sustainable development. The foamed ceramic wall tile has a water absorption rate of less than 0.4%, a density of 0.9-1.4 g / cm<3>, compressive strength of more than 8 MPa, breaking strength of more than 5 MPa, tensile strength of more than 2 MPa, a heat conductivity coefficient of 0.25-0.46 w / m.k, and a combustion performance of AI grade.

Description

technical field [0001] The invention belongs to the technical field of building ceramic materials and the field of lightweight foamed ceramics, and specifically relates to a medium-density foamed ceramic glazed decorative wall tile based on industrial solid waste utilization and rapid bare firing in a roller kiln and a manufacturing method thereof. Background technique [0002] Traditional ceramic tiles are generally solid and dense, with a density of 2.3-2.5g / cm 3 Whether it is used for exterior walls or interior walls, it will greatly increase the load-bearing capacity of the wall. When used for exterior walls of high-rise buildings, the safety is even worse. Large-scale ceramic tiles are used for high-rise exterior walls. It has been explicitly banned in many places, and because their thermal conductivity is relatively large, generally around 2.0w / m.k, they do not have the functions of heat insulation and sound absorption, and cannot be used for the insulation of building...
