Abstract
The invention relates to a microemulsion composite floatation agent for coal dressing and a preparation method. The microemulsion composite floatation agent is composed of No.0 diesel, alkylphenol polyoxyethylene-15, fatty alcohol-polyoxyethylene ether-7, fatty alcohol-polyoxyethylene ether-9, DL-2-octanol and glycerin. The preparation method includes firstly adding the No.0 diesel into a reaction tank, adding the alkylphenol polyoxyethylene-15, fatty alcohol-polyoxyethylene ether-7, fatty alcohol-polyoxyethylene ether-9as stirring, then adding the DL-2-octanol and glycerin, stirring at room temperature for 30 minutes, and subpackaging.
Description
Technical field
The present invention relates to coal separation microemulsified composite floating chemical and preparation method, specifically, is a kind of coal separation microemulsified composite floating chemical and preparation method.
Background technology
Modern coal mines mining mechanization degree is more and more higher, and the coal slurry content in coal is increasing, and primary slime content reaches 15%～30% of feed coal, even higher.This part coal slime (0.5mm level), if can not get effective sorting, recovery, will cause huge waste and loss to state coal resource, and flotation is to process the most effective means of coal slime.
Coal slime flotation carries out under interacting on solid, liquid, gas three phase boundary, and occurs in solid-liquid, solid and gas, liquid gas two interfaces and three interfaces.Floatation process is a very complicated physical chemistry and hydromechanical process, and active in this process is coal and other particle surface character and wettability difference.
Composite floating chemical is the new trend of flotation agent exploitation in recent years, and it has the dual-use function of " collecting and foaming " concurrently.The coal separation of the present invention invention is compound is that diesel oil, surfactant, fusel iol material are prepared according to a certain ratio and made microemulsion solution with flotation agent.
When microemulsified composite floating chemical prepared by the present invention uses because oil droplet disperses, on the boundary of oil droplet and water, aligning emulsifying agent molecule, when the drop disperseing and coal grain are while coming in contact, the emulsifying agent molecular energy of oil droplets promotes collecting agent on coal grain surface, to expand, cover, to cause whole coal grain surface hydrophobic to strengthen, improve the flotation activity of coal grain, promote the dispersion of diesel oil in coal slurry, increase the total surface area of oil film, not only can reduce the consumption of collecting agent, and can improve the selective of flotation, improve flotation speed and coal separation efficiency.
Summary of the invention
The object of this invention is to provide a kind of coal separation microemulsified composite floating chemical and preparation method.In order to achieve the above object, the present invention is by the following technical solutions:
