Method for producing heat-insulation decoration board by using semi-dry type pressing and granulating iron tailings and albite powder co-firing method

Abstract

The invention discloses a method for producing a heat-insulation decoration board by using a semi-dry type pressing and granulating iron tailings and albite powder co-firing method, and relates to thetechnical field of foaming ceramics. The method adopts the preparation technology with the following steps of firstly, mixing the foaming ceramic raw material of the iron tailings for 1h in a dry way, spraying misty water, enabling a paired roll granulator to produce particles, paving the albite powder with diameter smaller than 0.074mm in a fire-resistant die cushioned with ceramic fiber paper,forming thickness of 3 to 8mm, enabling a material distributor to uniformly add and distribute the particles onto the albite powder, and firing in a roller kiln or a tunnel kiln to form the heat-insulation decoration board, wherein a glass layer with thickness of 3mm is formed on the fired albite powder. The preparation method has the advantages that the preparation method is simple; in the firingprocess, the glass layer with thickness of 3mm on the fired albite powder is tightly bonded with the foaming ceramic material fired by the tailing formula, and the stripping and cracking are avoided;the heat conduction coefficient of the produced heat insulation decoration board is 0.08W / (m.0C), and the index requirements of the heat-insulation decoration board of an outer wall are met.

Description

technical field [0001] The invention relates to a method for producing a thermal insulation decorative board by co-firing semi-dry pressed granulated iron tailings and albite powder, and belongs to the technical field of foamed ceramics. Background technique [0002] At present, the thermal insulation and decoration integrated board is basically formed by pasting the thermal insulation layer and the decorative layer, which has a short life and is easy to delaminate and fall off, causing accidents. [0003] The foamed ceramic insulation board has high strength and is A1 fireproof. At present, it is bonded with organic glue when it is combined with the decorative layer, which cannot meet the A1 fireproof requirements, and it is also easy to delaminate and fall off. Contents of the invention [0004] In view of the above problems, the technical problem to be solved in the present invention is to propose co-firing of albite and iron tailings foamed ceramic raw materials, and u...
