Abstract

The object of the present invention is to further improve the dust suppression performance of the antifreeze type dust suppressant, provide a low freezing point wetting type dust suppressant and a preparation method thereof, which belong to the technical field of dust suppressant. The mass percent content of each raw material component of the dust suppressant of the present invention is: sodium lactate: 0.1-2%, polyacryl alcohol: 0.1-6%, glycerin: 2%-10%, binder: 0.1-5%, Epoxy resin: 0.2-2%, surfactant: 0.1-1%, emulsion: 0.1-3%, water: balance. The dust suppressant of the invention is reasonable in price, easy to popularize and use, wide in source of raw materials, easy to implement, non-toxic, tasteless, non-corrosive, easy to spray and the like. It can be used to suppress dust in exposed areas such as mine roads, urban roads, municipal construction, coal mine transportation, and storage yards.

Description

technical field [0001] The invention belongs to the technical field of dust suppressants, in particular to a low freezing point wetting type dust suppressant and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, people's attention to the environment is also increasing day by day. The problem of fugitive dust pollution in my country is relatively serious, which has aroused strong reactions from the society. [0003] Since the 1920s, western countries have begun to use the simplest dust suppressants to reduce coal dust in mines. Since then, chemical dust suppressants have appeared and gradually applied in mines, fossil fuel mining, transportation and storage. area. With the continuous innovation and development of chemical technology and polymer materials, more and more materials and methods have been applied to the innovative development of dust suppressants. So f...
