Abstract

The invention relates to the technical field of environmental protection, and particularly relates to an environment-friendly wetting-type dust suppressant and a preparation method thereof. The environment-friendly wetting-type dust suppressant disclosed by the invention comprises the following raw materials: a mixed surfactant, a fluorine-containing and / or organic silicon-containing surfactant, apenetrating agent and water, wherein the mixed surfactant is a mixture of a nonionic surfactant and an ionic surfactant. According to the environment-friendly wetting-type dust suppressant disclosedby the invention, the surfactants in the raw materials are all green, environmentally friendly and degradable, so that relatively high biodegradability is achieved, high wettability and permeability are achieved, dust suppression efficiency is high, and dust suppression requirements under various dynamic dust raising working condition environments can be met.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environment-friendly wetting dust suppressant and a preparation method thereof. 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 ...
