Sintered decorative brick of dry wall and manufacturing method thereof

Abstract

The invention provides a sintered decorative brick of a dry wall and a manufacturing method thereof. The decorative brick is made from the following raw materials in percentage by weight: 25-80 percent of shale, 10-30 percent of fly ash, 10-60 percent of metallurgy ore tailing or reservoir silt and 0-4 percent of admixture; the metallurgy ore tailing is one of a mineral gold ore tailing, a lead-zinc ore tailing, an iron ore tailing and an alumina ore tailing; and the admixture is one of chromium powder, manganese powder, cobalt powder and ferrous powder. The manufacturing method is achieved asfollows: coarsely rushing and milling the shale with the milling fineness less than or equal to 1mm, adding the fly ash, the metallurgy ore tailing or the reservoir silt and the admixture for mixing,adding water for stirring, then feeding the mixture to an ageing bunker to age for 72 hours, extruding the aged product by a high vacuum extruder for forming, treating the surface of the formed product, cutting and drying the formed product, and finally feeding the dried product to a calcining kiln to form a finished product. The invention uses the fly ash and the reservoir silt so as to save theenergy source and be beneficial to environmental protection; and the decorative brick has high compactness, high strength, favorable durability, good fireproofing function and elegant and beautiful appearance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a sintered dry wall decorative brick and a manufacturing method thereof. Background technique [0002] In the prior art, most of the building walls are sintered ordinary bricks or sintered hollow bricks, and then the walls are coated or decorated with mixed mortar, paint and ceramic tiles. The construction process is complicated and requires a large amount of mixed mortar, paint and Ceramic tiles and other plastering decorative materials, and the production technology mainly exists: raw material processing is not fine, resulting in rough appearance of the product; using ordinary extrusion molding methods, the density of decorative bricks is low, and the strength is not high; After the walls are built, plastering and exterior decoration are carried out. Contents of the invention [0003] The purpose of the present invention is to aim at the deficiencies in the prior ar...
