Preparation and application of strong-permeability moistening-enhancing material for coal seam water injection

Abstract

The invention discloses preparation and application of a strong-permeability and moisture-increasing type material for coal seam water injection. The preparation method comprises the following steps: step 1, preparing raw materials; step 2, dissolving sodium alginate; step 3, preparing modified sodium alginate; step 4, preparing a strong permeability and moisture enhancement type material; in the step 2, the addition amount of sodium alginate (SA) is 1.5 g, in the step 3, the addition amount of an initiator is 0.8 mol%, the addition amount of acrylamide (AM) is 3 g, and the addition amount of a caprolactam monomer (CPL) is 6 g, and in the step 4, the addition amount of dodecyl dimethyl betaine (BS-12) is 2.5 ml, and the addition amount of acetic acid (AcOH) is 2 ml. The environment-friendly, clean and efficient strong-permeability moistening-enhancing material is prepared by adopting a molecular modification technology for molecular modification, has the advantages of being low in price, environmentally friendly, non-toxic and high in wetting capacity, and can realize whole-course efficiency improvement and source dust reduction of dust prevention of an excavation operation environment.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to the preparation and application of a strong-osmosis-enhancing-wetting material for coal seam water injection. Background technique [0002] In places with severe dust pollution such as mining areas, thermal power plants, cement plants, metallurgical plants, and dust trucks, in order to achieve better dust suppression effects, dust suppression devices equipped with dust suppression agents will be equipped for dust suppression, but the existing dust suppression agents are lacking. It is environmentally friendly and has certain toxicity and corrosiveness, so it does not conform to the concept of environmental protection; the dust suppression effect depends on the wetting ability of the dust suppressant, but the wetting ability of the existing dust suppressant is limited, and the ideal dust suppression effect cannot be achieved.
