Concentrated environment-friendly dust suppressant and preparation method thereof

Abstract

The invention relates to a concentrated environment-friendly dust suppressant and a preparation method thereof. The preparation method specifically comprises the following steps of: 1) adding 100g ofpolyvinyl alcohol into 800ml of a water-in-water type reversed-phase anionic polyacrylamide emulsion with a molecular weight of 6,000,000 and a solid content of 30%, performing swelling for 5h, and then conducting stirring for 30min to obtain 900ml of an aqueous phase solution; and 2) adding 35ml of a styrene-acrylic emulsion with a solid content of 40%-50% into the aqueous phase solution, then adding 65ml of glycerol, and mixing the substances uniformly to obtain 1L of the concentrated environment-friendly dust suppressant. The environment-friendly dust suppressant has the advantages that: the environment-friendly dust suppressant has excellent stability of high flash point and low freezing point, an environment-friendly function is completely realized, a good dust suppression effect is achieved, and reagents used in the environment-friendly dust suppressant are all safe and environment-friendly products.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a concentrated environmental protection dust suppressant and a preparation method thereof. Background technique [0002] With the continuous expansion of urbanization and the rapid development of industrialization, the ensuing environmental pollution problems are becoming more and more serious, especially the problem of dust, such as inhalable particulate dust and aerosols above pm2.5 in the air, which have a great impact on human health. harm. The main dust in the air comes from bare land surfaces, stockpiles, excavation areas, fallow farmland, mining enterprises, etc. The traditional dust suppression method using dust-proof nets is not only ineffective, but also causes secondary damage after the dust-proof nets are weathered and broken. pollute. In recent years, dust suppression methods and technologies have been greatly innovated and developed. Spraying dust...

AI Technical Summary

Problems solved by technology

At this stage, there are various types of dust suppressants with different principles, and there are many problems. One is environmental protection problems, such as: easy to cause harm to green vegetation, harden the soil, and use various additives such as solvent oil to easily cause secondary pollution. Secondary pollution, etc., have brought new environmental problems

Second, the technical content of the product is low, there are problems such as high concentration and low cost, difficulty in dissolution and unfavorable construction, etc., which bring many unfavorable factors to the popularization and use of dust suppressants
