Abstract

The invention discloses a dust suppressant as well as a preparation method and an application thereof. Based on 100 parts by weight, the dust suppressant consists of 8-10 parts of pure acrylic emulsion, 0.2-0.4 part of sodium dodecyl sulfate, 0.2-0.4 part of sodium carboxymethyl cellulose, 1-2 parts of starch, 0.1-0.2 part of anhydrous sodium sulfate and the balance of water. The preparation method for the dust suppressant comprises the following steps: heating water until boiling, adding the pure acrylic emulsion and the sodium dodecyl sulfate, controlling the temperature to 75-95 DEG C to stir for 20-50 minutes, then, adding the starch and the anhydrous sodium sulfate, controlling the temperature to 75-95 DEG C to further stir for 20-60 minutes, then, adding sodium carboxymethyl cellulose to for further stir for 20-60 minutes, and cooling to the room temperature, thereby obtaining the dust suppressant which is environmentally friendly, low in cost and free of secondary pollution. The dust suppressant disclosed by the invention is used for suppressing dust in a powder storage yard, wherein the dust suppressing rate is up to over 85%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a dust suppressant, a preparation method thereof and an application thereof in suppressing powder dust. Background technique [0002] Many human activities generate dust. With the continuous development of my country's economy, the output and use of coal are also increasing, and the problem of dust in coal yards and ash yards has also attracted widespread attention; at the same time, with the high-intensity economic activities in cities and surrounding areas, large-scale Urban construction, high-speed development of road traffic, etc. have resulted in a large number of soil storage yards, which have caused serious pollution to the urban atmospheric environment, and have caused harm to human health and environmental ecology. [0003] The traditional method of dust suppression is to regularly sprinkle water on roads, construction sites and other places ...
