Abstract

The invention provides a composite crusting dust suppressant for application such as road dust suppression, mining area dust suppression, power plant dust suppression, construction dump dust suppression, and production and manufacturing industry dust suppression, and a preparation method thereof. According to the preparation method, common organic matters such as ethanediol, diethylene glycol andglycerinum are taken as main components, raw dust suppressant stock is synthesized through the steps such as pre-polymerization and bubbling auxiliary membrane forming of dust suppressant components,the diluted dust suppressant can be widely used in various scenes, and has strong effects such as wetting, bonding, coagulating, crusting and moisture absorbing and water holding on dust, the dust isprevented from secondary rising, the using cost is low, and the dust suppressant has broad commercial application prospects.

Description

technical field [0001] The invention belongs to the field of environmental protection. Specifically, the present invention relates to a composite crust dust suppressant and its preparation method, and the dust suppressant can be used in open, semi-open or closed places such as roads, mining areas, power plants, construction waste dumps, and manufacturing industries. Applications. Background technique [0002] The dust-proof technology of chemical dust suppressant has been developed rapidly abroad. The United States, Japan and other countries have new patents published every year. In mines, it is used to moisten roadways to accumulate dust and suppress coal dust in operations such as drilling and blasting. Over the past half century, with the in-depth study of chemical dust suppression technology, the improvement of people's environmental awareness and the development of modern chemical industry, the depth and breadth of dust suppressant research have expanded rapidly.
