Abstract

The invention relates to a self-crosslinking macromolecular dust suppressant and a preparation method thereof and belongs to the technical field of environmental pollution improvement and particularly relates to the self-crosslinking macromolecular dust suppressant and the preparation method thereof. The self-crosslinking macromolecular dust suppressant is characterized by being prepared by taking styrene (St) as a hard monomer, ethyl acrylate (EA), 2-ethyl hexyl acrylate (2-EHA) as a soft monomer, introducing acrylic acid (AA) and acrylamide (AM) as a functional monomer, diacetone-acryloamide (DAAM) and adipic dihydrazide (ADH) as a self-crosslinking monomer, taking persulfate as an initiator, alkyl diphenyl ether disulfonate (DSB) as an emulsifier and allyloxyl nonylphenol ether ammonium sulfate (DNS-86) as a reactive emulsifier by virtue of a seed emulsion polymerization method. The self-crosslinking macromolecular dust suppressant provided by the invention has excellent wear resistance, water resistance, resistance to acid and base and corrosion resistance and is an environment-friendly green product.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control, and specifically relates to a self-crosslinking polymer dust suppressant and a preparation method thereof, which are mainly used for controlling coal powder, mineral powder, muck transportation, municipal construction, open-pit mining, and bare land Wait for the flying of dust. Background technique [0002] With the development of industry and the improvement of people's living standards, environmental protection and effective use of resources have become the focus of attention of all countries in the world. Dust pollution is one of the world's public hazards. The dust pollution caused by open dusty sites such as various municipal engineering sites, material storage yards, demolition sites and other bare grounds has greatly endangered people's normal life and health, and destroyed the ecological environment. environment. According to data, dust pollution has become a com...
