Zusammenfassung: | 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 po |
