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 as follows: 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 the energy 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.
