Abstract

The invention discloses a phosphogypsum-based metal-like decoration material and a preparation method thereof. The phosphogypsum-based metal-like decoration material comprises the following raw materials by weight part: 60-130 parts of phosphogypsum, 70-90 parts of electrolytic yellow phosphorus slag and 3-9 parts of quicklime. The preparation method comprises the following steps: burdening, aging, moulding, performing autoclaved curing on a phosphogypsum base material, drying, and spraying to obtain the finished product. The phosphogypsum-based metal-like decoration material has the characteristics of simple construction process, good waterproof flame resistance, high compressive strength, high flexural intensity and strong weatherability, has good decorative effect as an interior decoration building material, consumes a lot of phosphogypsum, reduces natural stone exploitation, and has important meaning for environment protection and continuous development.

Description

technical field [0001] The invention relates to the field of chemical building materials, in particular to a phosphogypsum-based imitation metal decoration material and a preparation method thereof. Background technique [0002] Phosphogypsum is the main industrial by-product when phosphate and compound fertilizer enterprises use phosphate rock and sulfuric acid as raw materials to produce phosphoric acid. The wet-process phosphoric acid production process is to produce extraction slurry by decomposing phosphate rock powder with sulfuric acid, and then filtering to obtain phosphoric acid, which is filtered and washed. Phosphogypsum waste is generated in the process. [0003] With the development of ammonium phosphate industry and high-concentration phosphate compound fertilizer, the discharge of phosphogypsum is increasing year by year. At present, the annual increase of phosphogypsum discharge in the world is 280 million tons, and China is about 50 million tons, accounting ...
