Abstract

The invention discloses an environmentally-friendly multifunctional dust suppressant and a preparation method thereof. The environmentally-friendly multifunctional dust suppressant comprises the materials in percentage by weight: 0.05-2.50% of carboxymethylcellulose, 0.05-2.50% of chitosan, 0.1-0.5% of acetic acid, 0.25-1.00% of glycerol, 0.05-0.15% of sodium alkyl benzene sulfonate, 0.01-0.05% of copper sulfate, 2-20% of magnesium chloride and the balance of water. The dust suppressant provided by the invention is remarkable in dust suppressant and loss preventative effect. Compared with other dust suppressants, the preparation method has the following advantages: the machining process is simple and convenient, the cost is lower, the dust suppressant time is long, the performance cost ratio is high, and the components are independent. The liquor of the dust suppressant is free from any toxic and side effects and corrosive effect, and the dust suppressant can be biodegradable and is free from any secondary pollution. The dust suppressant provided by the invention can be widely applied to the fields of construction sites, cement plants and coal storage and transportation and dust suppression.

Description

technical field [0001] The invention relates to the field of dust suppression materials, and discloses an environment-friendly multifunctional dust suppression agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of society, the scale of construction facilities and other projects has increased day by day, the number of machinery has increased, and engineering activities have become increasingly complex. Unavoidable floating soil and dust in the process of engineering construction have led to dust pollution around the construction site. The dust pollution around the cement factory has also become a major public hazard. In addition, during the storage and transportation of coal, a large amount of coal dust will be generated, which will not only cause coal loss, waste natural resources, but also cause serious pollution to the environment. In addition, for coal piles, dust may also cause safety accidents. The methods...
