Problems solved by technology

[0003] Due to the self-contained roller kiln with no backing plate for sintering, energy saving and material saving, and perlite as a scarce functional mineral material is expensive and resources are scarce. At the same time, bulk solid waste such as tailings and red mud cannot be utilized as resources. These not only restrict the application and development of foamed ceramic composite panels, but also restrict the development of thermal insulation decoration materials and metallurgical industries

Abstract

The invention discloses a foamed ceramic composite plate based on shale and copper tailings as main materials and a production method of the foamed ceramic composite plate. The foamed ceramic composite plate comprises a foamed ceramic material, a toughened ceramic material and a decorative glaze material, and the materials are used for producing and molding the composite plate according to the steps of material weighing, ball milling, spray drying, dry-pressing molding, drying, decoration, firing and cold processing; the foamed ceramic composite plate disclosed by the invention is produced by adopting process methods including secondary distributing one-step molding, a composite decorating process, naked foaming firing without a liner plate, and crusting foaming; the product has a low coefficient of thermal conduction, a low volume density, a low rate of water absorption, a high strength, a high hardness and a high-fidelity stone decoration effect; and as a key material of a foamed ceramic composite plate external wall thermal insulation system, the foamed ceramic composite plate disclosed by the invention, together with adhesive mortar, anchoring parts and joint sealing materials, forms an external wall thermal insulation system, so as to meet requirements for integrated thermal insulation and decoration in various environments.

Description

technical field [0001] The invention relates to the field of foamed ceramic thermal insulation composite panels for buildings, in particular to a foamed ceramic composite panel based on shale and copper tailings as main materials and a production method thereof. Background technique [0002] There are two main types of existing foamed ceramic composite board products: one is a foamed ceramic composite board with a glazed decorative protective layer fired at one time, and the other is a foamed ceramic composite board with a decorative panel (ceramic, stone, paint, etc.) ) are connected by adhesives, connectors or self-adhesive. There are also two production methods for the existing decorative foamed ceramic composite panels: one is the sintering method using roller kilns, tunnel kilns, pusher kilns, and shuttle kilns with refractory backing plates; the other is using pearl kilns. Bare sintering in a roller kiln without a backing plate that has the characteristics of the rock...
