Problems solved by technology

[0003] However, as far as the current situation of dust pollution is concerned, the research on some dust suppressants in my country is not enough to meet the needs of practice.
Due to the lack of co-solvent and high-pressure dissolution state of ordinary dust suppressants, the dissolution of dust suppressants is incomplete, and dust below 2.5 microns cannot be effectively controlled; in addition, the raw materials of some dust suppressants are corrosive, which will cause secondary damage to the environment. Pollution; some organic dust suppressants are highly toxic, volatile, non-hydrophilic and refractory; or some dust suppressants have defects such as high cost

Abstract

The invention relates to a high-molecular polymer dust suppressant compound and a preparation method thereof. The high molecular polymer dust suppressant compound consists of a cellulose high-molecular compound, a polyoxyethylene type non-ionic surface active agent, glycerol, calcium chloride and water. The dust suppressant compound can form a curing layer on various dust-raising surfaces, bonds powder, particles and large objects on the dust-raising surfaces together and accordingly can effectively restrain dust raise. In addition, a dust suppressant does not contain heavy metal, is free of toxic or side effect, does not cause secondary pollution, is low in cost and convenient to spray and has great significance on environmental pollution, coal yard pollution, building construction site pollution, railway slope protection and the like along railway lines.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection. More specifically, the present invention relates to a polymer dust suppressant composition, and also relates to a preparation method of the composition. 【Background technique】 [0002] Aiming at the problem of dust pollution, countries have conducted a lot of research on it and achieved considerable results. The existing dust suppressant has a good dustproof effect, can effectively remove dust above 2.5 microns; can effectively reduce dust hazards; can effectively reduce and reduce material loss, and is in line with the national energy conservation and emission reduction policy. [0003] However, as far as the present situation of dust pollution is concerned, the research on some dust suppressants in my country is not enough to meet the needs of practice. Due to the lack of co-solvent and high-pressure dissolution state of ordinary dust suppressants, the dissolution of dust s...
