Abstract

The invention aims to further improve the dust suppression performance of an anti-freezing dust suppressant, provides a low-freezing-point wetting type dust suppressant and a preparation method thereof, and belongs to the technical field of dust suppressants. The dust suppressant is prepared from the following raw material components in percentage by mass: 0.1 to 2% of sodium lactate, 0.1 to 6% ofpolypropylene glycol, 2 to 10% of glycerol, 0.1 to 5% of an adhesive, 0.2 to 2% of epoxy resin, 0.1 to 1% of a surfactant, 0.1 to 3% of an emulsion and the balance water. The dust suppressant is reasonable in price, convenient to popularize and use, wide in raw material source and easy to implement, and has the characteristics of being non-toxic, tasteless, non-corrosive, easy to spray and the like. The dust suppressant can be used for dust suppression of exposed places 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, and in particular relates to a low-freezing-point wetting 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 environmental pollution caused by flying dust in our 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 suppressant to reduce coal dust in mines. Since then, chemical dust suppressants have appeared and been gradually used in mines, fossil fuel mining, transportation and storage, etc. area. With the continuous innovation and development of chemical processes and polymer materials, more and more materials and methods have been applied to the innovative deve...
