High-efficiency dust suppressant and preparation method thereof

Abstract

The invention relates to a high-efficiency dust suppressant, which is prepared by mixing a high molecular synthesis water-soluble polymer, a film forming aid, polyvinyl alcohol redispersion rubber powder, a dispersant and water in the part by weight ratio of (2-5):(0.2-0.8):(0.5-1.5):(0.2-0.8):(93-98), wherein the film forming aid is phenoxy propandiol; and the dispersant is an ammonium polyacrylate salt. A preparation method of the dust suppressant comprises the following steps of: putting normal-temperature water into a container; adding the obtained high molecular synthesis water-soluble polymer into water; stirring for 2 minutes; adding the polyvinyl alcohol redispersion rubber powder; stirring for 5 minutes; and slowly adding the film forming aid and the dispersant while stirring. The dust suppressant is nontoxic, harmless and noncorrosive, has a reasonable formula and a simple preparation process, and is easy and convenient to spray. When the dust suppressant is sprayed onto thesurface of a material, a solidified layer with a certain intensity can be formed on the surface of the material; and the dispersed material is enclosed below the solidified layer, so that the aim of preventing dust on the surface of the material is fulfilled.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a dust suppressant, especially a high-efficiency dust suppressant and a preparation method thereof. Background technique [0002] As we all know, during the production process of enterprises, a large amount of bulk materials, such as coal, ore or other raw materials, are often stored or transported. These bulk materials are easy to blow up with the wind when they are stacked or transported in the open air. Flying dust not only pollutes the air, endangers human health, but also causes material loss and economic losses for enterprises. Dust may also cause safety accidents. In the open-air coal storage plants of some thermal power plants, due to the flying coal dust, the heating pipes, cables, etc. may cause fire hazards due to the spontaneous combustion of deposited dust; Flying, it is easy to cause equipment failure and safety hazards to railway locomoti...

Problems solved by technology

[0003] The existing solution is to cover the bulk material with tarpaulin or sprinkle water, but neither can effectively solve the problem. Covering the tarpaulin reduces the operating efficiency, makes recycling difficult, and the cost is high; water sprinkling can only prevent dust for a short time, and frequent watering is required. This method is a serious waste of energy, and it cannot prevent dust and splash for long-term stacked materials and long-distance transported bulk goods. Therefore, it is very necessary to develop new and efficient dust suppressants
