Abstract

The invention discloses a preparation method of a special dust suppressant for the soil surface, and belongs to the technical field of environmentally-friendly materials. The preparation method comprises the following steps: mixing and swelling polyvinyl alcohol with water, and performing heating and stirring for dissolving to obtain a polyvinyl alcohol solution; mixing and swelling chitosan withwater, and performing heating and stirring for dissolving to obtain a chitosan solution; mixing and swelling sodium alginate with water, and performing heating and stirring for dissolving to obtain asodium alginate solution; mixing the polyvinyl alcohol solution, the chitosan solution, the sodium alginate solution, a cross-linking agent, chitosanase and algae according to a certain weight part ratio, and carrying out ultrasonic dispersion to obtain a dispersion; carrying out spray drying on the dispersion at a low temperature to obtain coated microcapsules; and stirring and mixing the coatedmicrocapsules, isocyanate, water, a surfactant and nano-metal oxide to obtain the special dust suppressant for the soil surface. The special dust suppressant for the soil surface has the advantages ofexcellent water retention property, excellent water stability and excellent wind erosion resistance.

Description

technical field [0001] The invention discloses a preparation method of a special dust suppressant for soil surface, which belongs to the technical field of environmental protection materials. Background technique [0002] The hazards of dust are well known, and the research on the prevention and control of dust in open-air storage coal piles and railway coal transportation has never stopped for decades. In the prior art, one of the most novel and effective methods is chemical dust suppression, which has been paid great attention to since it appeared in the 1930s. Coal resources still occupy the largest proportion in energy consumption. At present, there are a large number of bulk coal storage yards and coal transportation railway lines. The coal pollution caused is very large, which not only brings huge economic losses to coal storage and transportation enterprises, but also causes surrounding environmental pollution, which seriously affects the production and life of resid...
