Description
Technical Field
The invention relates to the technical field of underground dust suppression, in particular to an underground descaling dust suppressant and a preparation method thereof.
Background
Coal mining is one of the most serious industries harming productive dust. The dust in the underground coal mine harms the health of workers, pollutes the working environment and damages the operation equipment. Currently, most industrial and mining enterprises in China mainly adopt dust suppression measures such as spraying water, adding a moisturizing dust suppressant, a solid moisture absorbent and soil fixation. Under the influence of water surface tension, when pure water is used for dust prevention, fine dust particles are difficult to wet by water, and a good effect cannot be achieved. The surface tension of water can be reduced by adding the dust suppressant, and the dust suppression efficiency is improved, so that the added dust suppressant is widely applied to the aspect of dust prevention and reduction of mine roadways.
Mine backwater in northwest areas is generally high-salt water, the content of calcium and magnesium ions is high, and the spraying pipeline can be scaled when the mine backwater is directly used for dustproof operation without treatment, so that the use of the dust suppressant is seriously influenced.
Chinese patent publication No.: CN102465711B discloses a composite dust suppressant for coal mine and a preparation method thereof, wherein the composite dust suppressant comprises 0.05-1.00% of fatty alcohol-polyoxyethylene ether (JFC), 0.05-1.00% of Sodium Dodecyl Benzene Sulfonate (SDBS), 0.01-0.50% of Polyacrylamide (PAM), 0.02-0.50% of polyaluminium chloride (PAC) and the balance of water. The components are all water-soluble substances, and can be directly sprayed by using the original water spraying system.
Chinese patent publication No.: CN105754552A discloses a quaternized chitosan mine dust suppressant and a preparation method thereof, wherein fatty alcohol-polyoxyethylene ether (JFC) 0.05-1.00%, quaternized chitosan 0.04-0.10% and water 99.80-99.91%. Low cost, natural degradation and less irritation.
However, the dust suppressant in the above patent can generate structure when the backwater in the mine is high salt water during the use process, thereby reducing the dust suppression efficiency in the mine.
Disclosure of Invention
Therefore, the invention provides an underground descaling dust suppressant and a preparation method thereof, which are used for solving the problem that scaling and dust suppression cannot be simultaneously solved in a high-salt water environment in the prior art.
On one hand, the invention provides an underground descaling dust suppressant, which comprises the following components in parts by weight: 5-10 parts of sodium dodecyl benzene sulfonate; 10-30 parts of sodium silicate; 5-10 parts of sodium carboxymethyl starch; 5-9 parts of glycerol; 2-5 parts of nitrilotriacetic acid; 93.6 to 98.83 portions of water.
Preferably, the downhole descaling dust suppressant comprises the following components in parts by weight: 10 parts of sodium dodecyl benzene sulfonate, 30 parts of sodium silicate, 10 parts of sodium carboxymethyl starch, 9 parts of glycerol, 5 parts of nitrilotriacetic acid and 98.83 parts of distilled water.
Preferably, the downhole descaling dust suppressant comprises the following components in parts by weight: 5 parts of sodium dodecyl benzene sulfonate, 10 parts of sodium silicate, 5 parts of sodium carboxymethyl starch, 5 parts of glycerol, 2 parts of nitrilotriacetic acid and 93.60 parts of distilled water.
Preferably, the downhole descaling dust suppressant comprises the following components in parts by weight: 8 parts of sodium dodecyl benzene sulfonate, 20 parts of sodium silicate, 8 parts of sodium carboxymethyl starch, 7 parts of glycerol, 4 parts of nitrilotriacetic acid and 95.30 parts of distilled water.
Further, when the underground descaling dust suppressant is stored, the components can be stored independently or prepared into a solution according to a ratio for storage.
In another aspect, the invention provides a method for preparing a downhole descaling dust suppressant, comprising the following steps:
step 1: respectively selecting specified parts by weight of sodium dodecyl benzene sulfonate, sodium silicate, sodium carboxymethyl starch, glycerol and nitrilotriacetic acid, and respectively dissolving in water;
step 2: and dissolving the materials in water, and stirring until the solution is colorless and transparent to prepare the underground descaling dust suppressant.
Further, the preparation process is carried out under normal temperature and pressure environment.
Further, the stirring time of the solution is 10-30 min.
Compared with the prior art, the descaling dust suppressant provided by the invention has the beneficial effects that the descaling dust suppressant can be used under the condition that mine backwater is high-salinity water, so that the problems of scaling and dust suppression are solved simultaneously. The components of the underground descaling dust suppressant are sequentially dissolved in water according to the mass ratio and the sequence, and the mixture is fully stirred and mixed for use. Or stirring the components except water, and dissolving in water at a certain ratio. The above processes are all operated at normal temperature.
Furthermore, the descaling dust suppressant can be prepared into a solution for storage, can be stored independently according to components and can be prepared when in use, so that the service life of the descaling dust suppressant is prolonged.
Further, the components of the invention have the following functions:
sodium dodecylbenzenesulfonate: the sodium dodecyl benzene sulfonate is neutral, is sensitive to water hardness, is not easy to oxidize, has strong foaming power and high detergency, is easy to be compounded with various auxiliaries, has lower cost, mature synthesis process and wide application field, and is an excellent anionic surfactant. The sodium dodecyl benzene sulfonate has obvious detergency effect on granular dirt, protein dirt and oily dirt, excellent detergency on granular dirt on natural fiber, raised detergency with the raised washing temperature, high protein dirt effect and rich foam. The sodium dodecyl benzene sulfonate is mainly used for preparing various liquid, powder and granular detergents, cleaning agents and the like. Meanwhile, the sodium dodecyl benzene sulfonate is used as an anionic surfactant, has good surface activity and strong hydrophilicity, and effectively reduces the tension of an oil-water interface to achieve the emulsification effect. Therefore, the sodium dodecyl benzene sulfonate is widely applied to the preparation of emulsion such as cosmetics, foods, printing and dyeing auxiliaries, pesticides and the like.
Sodium silicate: colorless orthogonal bipyramid crystals or white to off-white blocks or powder, is easily soluble in water, soluble in dilute sodium hydroxide solution, insoluble in ethanol and acid, strong in binding power, high in strength, good in acid resistance and heat resistance, and poor in alkali resistance and water resistance. The silicon compound is used for manufacturing various silicate products such as silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layered silicon, instant powdery sodium silicate, potassium sodium silicate and the like in a chemical system, and is a basic raw material of the silicon compound.
