Abstract

The invention relates to the field of a pollution prevention method and provides a preparation method of a micro-fog dust depressor, aiming at solving the problems that a dust removal effect is not good when a water spraying device is used for removing dust in a construction site at present. The preparation method comprises the following steps: adding 60 to 90 parts by weight of a modified organic silicon surfactant and 20 to 30 parts by weight of dodecyl dimethyl betaine into 10 to 20 parts by weight of a natural macromolecular emulsifier; stirring for 0.5h to 1.5h and adding 1 to 10 parts by weight of a stabilizer to obtain the micro-fog dust depressor. By adopting the micro-fog dust depressor provided by the invention, a non-permanent waterproof shell can be formed on the outer surface of a material stack and dust dissipation is controlled; the materials are protected from corrosion of wind, rain and snow, the loss of the materials is reduced and the environment is beautified.

Description

technical field [0001] The invention relates to the field of pollution prevention methods, in particular to a preparation method of a micro-mist dust suppressant. Background technique [0002] With the rapid growth of my country's economy, urban air pollution is rapidly emerging as a major environmental problem. Statistical data show that although the emission of soot and dust in my country has a downward trend year by year, the main pollutants affecting urban air quality are still particulate matter. The reason is that construction dust pollution has become one of the main sources of total suspended particulate matter in urban air. First, it is an important factor that plagues urban air quality. There are three main sources of construction dust: one is the dust generated in the process of building construction foundation engineering, earthwork engineering, structural engineering, etc.; The third is dust pollution caused by factors such as uneven roads or excessive loading ...
