Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a dust suppressant, in particular to a dust suppressant used in the railway transportation of bulk materials and a preparation method thereof. Background technique [0002] Bulk materials are easily scattered during railway transportation, causing dust pollution and causing great harm to the environment along the railway and the physical and mental health of residents. In recent years, some researches have been carried out at home and abroad on the prevention and control of dust pollution along the railway transportation, and some achievements have been made. Then, with the enhancement of people's awareness of environmental protection, higher requirements are put forward for the prevention and control of dust pollution. Chinese patent application "Dust Suppressant for Railway Mineral Powder and Coal Transportation and Its Preparation Method" (application number: 200121000190...
