Problems solved by technology

To improve the dust removal effect, the surface tension of water must be changed, and a wetting agent needs to be added to improve the dust removal efficiency. By studying the wetting ability of this compound surfactant solution to coal dust, most of the wetting agents are just a simple Compounding, free combination, short suspension time in the air and poor adhesion in the field application process lead to low dust removal efficiency, and less consideration is given to environmental protection, pollution, and harm to human skin in material selection, and there are obvious defects.

Abstract

The invention discloses a polynary ionic wetting agent for inhibiting mine dust and a preparation method thereof, which are applied to the inhibition of a lot of dust produced during the production ofa mining working face of a mine. A variety of anionic, cationic, nonionic and neutral ionic surfactants are first isotropically combined and compounded, then anisotropically cross-compounded, added with water, put into a chemical reaction kettle and agitated under 120 DEG C for 2 hours while pressure is kept at 0.8MPa; inorganic salt is added to improve the ionized characteristic of the mixture,and agitation is carried out for 1 hour; adhesive is added to improve the capturing capability of mixture droplets, curing and reinforcing agent is added to increase the suspension period of the droplets in the air, and agitation is carried out for 2 hours; imidazole ionic liquid is added as an additive, agitation is carried out for 1 hour, the mixture is depressurized, cooled and taken out of thekettle, and thereby the polynary ionic wetting agent is formed. The wetting agent can greatly improve wetting capability and capturing capability on respirable dust and prolong the suspension life ofdroplets; the mine dust suppression cost is low, skin cannot be injured, machine corrosion is little, and the polynary ionic wetting agent has good applicability and environment-friendliness.

Description

technical field [0001] The invention relates to a multi-component ion wetting agent for suppressing mine dust and a preparation method thereof, which is especially suitable for mining areas where respirable dust is relatively serious in mining working faces, and can achieve better dust suppression effect, good stability and good environmental protection performance. Background technique [0002] At present, my country's coal industry is in a period of green transformation and development. Coal dust is an inevitable product in the process of coal production and processing and has been a serious threat to the safety of mine production. The main manifestations are coal dust explosions, pneumoconiosis occupational diseases, and environmental pollution. In recent years, with the development of coal mining technology, the mining equipment has become increasingly large-scale, and the per unit yield of the working face has continued to increase. The ensuing coal dust hazard has beco...
