Phosphogypsum-based facade greening wallboard and preparation method thereof

Abstract

The invention discloses a phosphogypsum based elevation greening wallboard and a preparation method thereof. The preparation method of the phosphogypsum based elevation greening wallboard comprises steps as follows: slurry containing 80%-90% of semi-hydrated phosphogypsum, 1%-5% of a foaming agent and 10%-15% of fibers is poured into a mold provided with geocells and is subjected to casting to be latticed, flexible reinforced materials are arranged in lattices, the slurry can be subjected to drying sintering or natural drying forming, then plant growing geocells are filled with plant culture media, and grass seeds are scattered on two sides of the plant culture media in advance or plants are grown on the two sides of the plant culture media. According to the preparation method, solid waste is adopted as a main material, waste is changed into wealth, and comprehensive utilization of the waste is realized; a product is rich in bubbles, thereby being low in density, light in weight and low in transportation cost; by means of rich fibers in the product, the tensile property of the product is good; by means of polymer yarn in the product, the bending resistance and the fracture resistance of the product are good; the phosphogypsum based elevation greening wallboard has functions of beautifying the environment and purifying air, has certain sound absorption and insulation effects, is low in manufacturing cost and has good market application prospect.

Description

technical field [0001] The invention relates to the technical field of greening wallboard manufacturing, in particular to a phosphogypsum-based facade greening wallboard and a preparation method thereof. Background technique [0002] The invention patent with the publication number CN102409625A discloses a plant sound insulation wall, which includes a support column, one or more plant cultivation boxes are fixed on the support column, and several sound insulation fins are arranged outside the plant cultivation box. The fins form an oblique angle with the horizontal plane. The plant sound insulation wall of the present invention not only plays the role of beautifying the road, preventing visual fatigue and absorbing carbon dioxide and harmful gases, but also can perform sound insulation and noise reduction through the simultaneous action of sound insulation fins and complex overlapping plant stems and leaves, greatly reducing Compared with the traditional simple sound insula...

AI Technical Summary

Problems solved by technology

[0003] However, the manufacture and installation of the plant sound insulation wall in the above-mentioned patent is complicated and costly, and support columns and sound insulation fins need to be provided, and the support columns and sound insulation fins are easy to wear and tear
