Abstract

The invention pertains to the technical field of composite material science and environmental protection and relates to opening coal dust polluting inhibitor and the preparation method thereof. The inhibitor is the hydrophilic material compounded by a plurality of compounds, and every compound and the weight percentage thereof is that: 15-20 percent main film forming resin, 25-30 percent auxiliary film forming resin,1-2 percent thickening agent, 15-20 percent dispersant, 2-3 percent mould inhibiting antiseptic agent, 1-2 percent anti-sedimentation agent, 2 percent defoamer, 15-20 percent powder and 3-5 percent color paste. The invention adopts the theory of gravity flow mat gloss solidification, which effectively overcomes the disadvantages of uneven film forming thickness, long film forming time, poor stability of film layer, etc of original self-solidification inhibition materials. The invention has low price, and production thereof is simple and practical; in addition, the invention has remarkable economic, environmental and social benefits, and is applicable to treat raised dust pollution in the fields of shipping, power, mine, road, metallurgy, etc.

Description

technical field [0001] The invention belongs to the technical field of composite material science and environmental protection, relates to an open coal dust pollution inhibitor and a preparation method thereof, and is applied to the treatment of open dust pollution. Background technique [0002] The use of coal in my country's energy structure has always been dominant (currently accounting for more than 80%). The main storage places of coal in my country are distributed in coastal coal docks, coal-fired power plants and large and medium-sized coal mines. Every year, a large amount of coal is stored in coal yards. These coals not only occupy a large amount of land, but also due to the characteristics of coal itself that are easy to weather The pulverization of a large amount of coal, in the windy weather in the dry season every year, the dry and fine coal powder on the surface is easy to fly with the wind, resulting in dust pollution, forming a large area of ​​open dust source...
