Dust suppressant and preparing method thereof

Abstract

The invention provides a dust suppressant and a preparing method thereof, and relates to the field of environment protection. The dust suppressant is prepared from sodium alginate, hydroxypropyl starch, propylene glycol, ethylene glycol, sodium sorbate, sodium diacetate, sodium lignin sulfonate, 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate) and calcium chloride. By means of the dust suppressant, the surface tension of dust can be reduced, dust can be rapidly wetted, gathered and settled, cured films with certain strength and tenacity can be formed on the surfaces of dust, and dust is prevented from rising along with wind and effectively prevented from polluting the environment. According to the dust suppressant, as the calcium chloride is used as an anti-freezing assistant, and the sodium diacetate and the sodium sorbate are used as sterilizing agents, the freezing problem of a dust suppressant in winter can be solved, and harmful bacteria in dust surrounding air can be killed; in addition, the adopted raw materials can be easily degraded, secondary pollution is avoided, the dust suppressing effect is obvious, the application range is wide, and the dust suppressant and the preparing method are worthy of application and popularization.

Description

【Technical field】 [0001] The invention relates to the field of environmental protection, in particular to a dust suppressant and a preparation method thereof. 【Background technique】 [0002] Dust refers to solid particles suspended in the atmosphere, which can cause low visibility in the surrounding atmosphere, and is an important factor that causes workers to suffer from pneumoconiosis and reduces environmental quality. Almost all mines and factories and mines can produce dust in the production process, such as mining and tunnel drilling, blasting, handling, etc., ore crushing, grinding, packaging and transportation, etc.; casting, foundry, sand cleaning, etc. in the machinery industry; As well as industries such as glass and refractory materials, they can be exposed to a lot of dust. Dust deposited on power transmission cables may easily cause spontaneous combustion and fire, and deposited on vehicle equipment may easily cause safety accidents such as equipment failure an...

Problems solved by technology

Although this method is simple and easy to implement, due to the weak binding force between dust and water molecules and the easy evaporation of water, it is impossible to form a dense solidified film on the dust surface, which cannot meet the needs of long-term dust suppression.

[0003] The invention with the publication number CN102277135A discloses "an environmentally friendly degradable dust suppressant and its preparation method". The dust suppressant has the functions of film formation, wetting, and coagulation. The complete, strong and tough shell membrane keeps the dust confined in the shell, avoids air pollution, and reduces material loss, but the dust suppressant has no obvious inhibitory effect on the bacteria in the surrounding air, and it will freeze when used in cold winter Phenomenon, spraying on the surface of the material will freeze and become brittle or even impossible to spray, and the dust suppression effect will be weakened
