Abstract

The invention discloses a preparation method of a road dust suppression film-forming agent. According to the method, an aqueous polymerization method is adopted, vinyl acetate, methyl acrylate, ethylacrylate, acrylic acid and the like are used as main monomers, and hydroxyethyl acrylate, hydroxypropyl acrylate, acrylamide, dimethyl diallyl ammonium chloride, methacryloyloxyethyl trimethyl ammonium chloride and the like are used as auxiliary monomers; use of water-soluble peroxides as initiators, the road dust suppression water-based polymer film-forming agent with resolubility is synthesized;the product has excellent bonding performance on raised dust on a road; the road dust can be effectively inhibited at low use concentration; particles formed by the water solution and dust are easilyremoved by a road cleaning machine, and can be dissolved again by rainwater or sprinkled water after forming a film with the dust on a road, so that the cleanness of the road is ensured, and the prepared water solution has biodegradability, does not influence the growth of trees on two sides of the road, does not harm pedestrians on the road and the environment, and does not cause secondary pollution.

Description

technical field [0001] The invention relates to the field of environmental protection materials, in particular to a preparation method of a road dust suppression film-forming agent and a water-resoluble road dust suppression film-forming agent. Background technique [0002] For dust suppressants, a lot of research has been carried out by all walks of life in our country, and a variety of dust suppressants have been formed for different scenarios, such as transportation dust suppressants, building dust suppressants, train dust suppressants, coal covering agents, coal crusts agent and coal flow dust suppressant, etc. However, the materials needed for road dust suppression should be different from those used for mine and construction site dust suppression. The main reason for this is the need to maintain the cleanliness and flushability of road surfaces. Although the dust suppressant prepared from high molecular polymers has excellent capture, wetting, bonding and coagulation...
