Abstract

The invention discloses a water-based dust suppressant which is prepared from the following raw materials in parts by weight: 20-25 parts of magnesium chloride, 15-18 parts of sodium polyacrylate, 4-8 parts of polylactic acid, 5-9 parts of hydroxyethyl acrylate, 1-3 parts of sodium dodecylsulfonate, 1-2 parts of polyethylene glycol laurate, 2-5 parts of zinc dialkyl dithiophosphate, 12-16 parts of xanthan gum, 7-10 parts of sodium silicate, 1-2 parts of pentaerythritol trimethacrylate, 3-6 parts of sodium hexametaphosphate, 5-9 parts of calcium stearate, 8-12 parts of soluble starch derivative and 100-120 parts of water. The invention also discloses a preparation method of the water-based dust suppressant. The water-based dust suppressant prepared according to the invention has advantages of excellent dust suppression effect, long dust suppression period, low dosage and stable performance.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water-based dust suppressant and a preparation method thereof. Background technique [0002] Dust pollution is one of the main factors leading to environmental pollution. In production and storage sites such as ports, power plants, cement plants, and coal storage yards, as well as during railway and road transportation, a large amount of dust is often generated, which not only directly threatens the safety of production, but also causes great pollution to the surrounding environment. [0003] Dust pollution is particularly serious in surface mining. With the continuous increase of open-pit mining in my country, the production intensity continues to increase, the level of mechanization continues to improve, and the dust pollution in production operations is becoming more and more serious. Dust in open-pit mines is concentrated in drilling rig perforation opera...
