[0016] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below in conjunction with the embodiments.

[0017] As analyzed in the background technology of this application, the dust suppressants in the prior art have the problems of polluting the environment, corroding metals and having low dust suppression efficiency. In order to solve this problem, this application provides a dust suppressant composition, a dust suppressant and a preparation method thereof.

[0018] In a typical embodiment of the present application, a dust suppressant composition is provided, which includes, by weight percentage, 0.5% to 2.0% of a surfactant, 0.1% to 0.5% of a binder, 0.05% to 0.1% of a stabilizer, 1.0% to 3.0% of a wetting agent, 0.05% to 0.2% of a corrosion inhibitor, and the balance is water.

[0019] The addition of corrosion inhibitors helps to reduce the corrosive effects of dust suppressants on metal equipment, thereby helping to extend the service life of the equipment. The addition of surfactants and wetting agents helps to increase the amount of dust suppressants adhere to dust particles. The addition of adhesives helps to increase the bonding force between dust particles and dust suppressants, thereby helping to form a stable particle covering layer, and further helping to reduce the secondary dusting of the particle covering layer caused by external factors such as wind. The addition of stabilizers helps to maintain the stability of dust suppressants under different environmental conditions, thereby helping to extend the dust suppression effect of dust suppressants. It is preferred to control the weight percentage of each component in the dust suppressant within the above range, which helps to give full play to the synergistic effect of each component, thereby helping to further improve the dust suppression effect and stability of the dust suppressant and reduce the corrosion of the dust suppressant to metals and pollution to the environment. All materials used are non-toxic and environmentally friendly, will not irritate the human respiratory tract, and will not cause harm to the environment.

[0020] In one embodiment of the present application, the mass ratio of the above-mentioned surfactant, wetting agent and corrosion inhibitor is 1:1-1.5:0.1-0.2.

[0021] Surfactants reduce the surface tension of liquids, increase the spreadability and permeability of liquids on the surface of loess and coal dust particles, and make it easier for droplets to cover dust particles, thereby helping to form a uniform protective film. Wetting agents change the arrangement of water molecules, making it easier for liquids to penetrate into the surface of dust particles, which helps to further reduce the surface tension of liquids, increase wettability and penetration depth. When surfactants are combined with wetting agents, they enhance the distribution efficiency of wetting agents on the surface of particles, allowing the wetting agents to cover particles more evenly, thereby improving the wettability of the entire dust suppression system, and further helping to reduce dust resuspension. In addition, wetting agents can penetrate into smaller gaps with the help of surfactants, helping to make the dust suppressant cover particles more comprehensively. Corrosion inhibitors help slow down the corrosion process and protect metal surfaces from erosion by corrosive substances by forming a protective film on the metal surface. In dust suppressants, corrosion inhibitors reduce the corrosion of dust suppressants on metal equipment. The combination of corrosion inhibitors with surfactants and wetting agents helps to improve their uniformity and durability of distribution on metal surfaces. Surfactants can help corrosion inhibitors better adhere to metal surfaces. At the same time, wetting agents improve the permeability of corrosion inhibitors, enabling them to form a uniform protective layer on the metal surface.

[0022] Therefore, the combination of the three can have the following effects:

[0023] (1) Enhanced dust suppression performance: The synergistic effect of surfactants, wetting agents and corrosion inhibitors significantly enhances the dust suppression effect of dust suppressants. Surfactants reduce the surface tension of liquids, and wetting agents enhance the permeability of liquids. The combined effect of the two makes it easier for liquids to cover dust particles and inhibit the re-suspension of dust. The addition of corrosion inhibitors can reduce the corrosiveness of liquids to equipment.

[0024] (2) Improved stability: The appropriate ratio of wetting agent and corrosion inhibitor helps to improve the stability of the solution. The wetting agent helps to evenly distribute the active ingredients in the solution and prevent phase separation caused by surfactants. The protective layer formed by the corrosion inhibitor can also stabilize the metal surface and prevent the influence of metal ions on the stability of the solution. It improves the corrosion effect of traditional dust suppressants on the machinery on the open-pit coal mine spoil dump due to surfactants and water molecules, making the on-site use of dust suppressants more extensive and with more application scenarios.

[0025] It can be seen that it is preferred to control the mass ratio of the surfactant, the wetting agent and the corrosion inhibitor within the above range, which helps to further improve the dust suppression effect and stability of the dust suppressant and reduce the dust suppression agent's corrosion to metals and pollution to the environment.

[0026] In one embodiment of the present application, the corrosion inhibitor is selected from any one or more of diammonium phosphate, monoammonium phosphate, sodium citrate, sodium gluconate and aminosulfonic acid; preferably, the corrosion inhibitor is a combination of diammonium phosphate and sodium gluconate, and the mass ratio of diammonium phosphate to sodium gluconate is 1:1 to 3.

[0027] Diammonium phosphate dissociates in water to form phosphate ions (PO 4 3- ) and ammonium ions (NH 4 + ), phosphate ions can form an insoluble phosphate protective layer with metal ions (such as iron ions) on the metal surface, preventing the dissolution of metal ions and inhibiting their oxidation reactions, thereby reducing corrosion. At the same time, ammonium ions can also neutralize acid radical ions in acidic environments, further reducing corrosivity. Secondly, sodium gluconate has excellent chelating and dispersing effects, which can chelate metal ions such as calcium and magnesium in water to prevent them from depositing and forming scale. In addition, sodium gluconate can form a soluble complex with iron ions, inhibit the formation and deposition of iron oxide, and effectively protect the metal surface.

[0028] The combination of diammonium phosphate and sodium gluconate can produce the following synergistic effects:

[0029] (1) Forming multiple protective layers: The phosphate layer formed by diammonium phosphate on the metal surface provides the first physical barrier, which helps reduce the direct contact of the metal surface with corrosive substances. The chelation effect of sodium gluconate forms a second layer of chemical protection on the metal surface, which can further enhance the protective effect of the metal surface through chelation.

[0030] (2) Inhibit corrosion ions: If there are iron ions on the metal surface, phosphate ions can form insoluble iron phosphate precipitation with iron ions, and sodium gluconate chelates and stabilizes these metal ions to prevent them from participating in corrosion reactions. The combination of the two can effectively reduce the formation of metal oxides and inhibit the electrochemical corrosion process.

[0031] (3) Enhanced buffering effect: The ammonium ions in diammonium phosphate help buffer the pH value of the solution and prevent corrosion caused by increased acidity. Sodium gluconate, as a weak acid salt, can stabilize the pH value of the solution and further reduce the solution's corrosiveness to metals.

[0032] It can be seen that it is preferred to control the type of corrosion inhibitor within the above range, which helps to further improve the synergistic effect between the corrosion inhibitor and other components in the dust suppressant, thereby helping to further reduce the corrosion of the dust suppressant to the metal.

[0033] In order to further increase the adhesion of the dust suppressant to the dust particles, in one embodiment of the present application, the above-mentioned surfactant is preferably an alkyl polyglycoside; preferably, the alkyl polyglycoside is selected from any one or more of decyl glucoside, lauryl glucoside and decyl lauryl glucoside.

[0034] In one embodiment of the present application, the wetting agent is selected from any one or more of ethanol, sorbitol, maltitol and trehalose.

[0035] It is preferred to control the type of wetting agent within the above range, which helps to further improve the synergistic effect of the surfactant and the wetting agent, thereby helping to improve the wettability and permeability of the dust suppressant, and further helping to further increase the adhesion amount of the dust suppressant to the dust particles.

[0036] In one embodiment of the present application, the mass ratio of the above-mentioned binder to the stabilizer is 1:0.1-0.25; and / or the binder is selected from any one or more of polyacrylamide, sodium polyacrylate, polyvinyl alcohol and sodium carboxymethyl cellulose; and / or the stabilizer is selected from any one or more of methyl methacrylate, guar gum and chitosan.

[0037] The stabilizer can be used as a cross-linking agent to finely control the viscosity of the adhesive. It is preferred to control the mass ratio of the adhesive to the stabilizer within the above range, which helps to further improve the bonding force between the dust suppressant and the dust particles. It is preferred to control the types of the adhesive and the stabilizer within the above range, which helps to improve the synergistic effect between the two, thereby helping to further improve the bonding force between the dust suppressant and the dust particles, the stability of the dust suppressant in different environments, and prolong the dust suppression effect of the dust suppressant.

[0038] In one embodiment of the present application, the dust suppressant composition further includes 0.1% to 0.5% of a pH adjuster; and / or the pH adjuster is selected from any one or more of soda ash, citric acid, sodium bicarbonate and lactic acid; and / or the dust suppressant composition further includes 1.0% to 5.0% of a solubility aid, and / or the solubility aid is selected from any one or more of ethylene glycol, propylene glycol, glycerin and polyethylene glycol; and / or the dust suppressant composition further includes 0.2% to 1.0% of a viscosity regulator; and / or the viscosity regulator is selected from any one or more of hydroxypropyl methylcellulose, hydroxyethyl cellulose and xanthan gum.

[0039] The addition of a pH adjuster helps to make the pH value of the dust suppressant approach neutrality, thereby helping to reduce the impact of the pH value of the dust suppressant on the environment. The addition of a solubility aid and a viscosity modifier helps to make the dust suppressant easy to apply through various spraying devices, and can be quickly operated without special treatment, thereby helping to improve the convenience of using the dust suppressant. It is preferred that the type of pH adjuster is within the above range, which helps to improve the neutralization effect of the pH adjuster on the corrosion inhibitor, so that the pH of the dust suppressant approaches neutrality. It is preferred to control the types of solubility aids and viscosity modifiers within the above range, which helps to further improve the uniformity and stability of the dust suppressant, so that the dust suppressant is easy to apply through various spraying devices, and can be quickly operated without special treatment, thereby helping to improve the convenience of using the dust suppressant.

[0040] In another typical embodiment of the present application, a dust suppressant is provided, which is prepared by mixing a dust suppressant composition, and the dust suppressant composition is the aforementioned dust suppressant composition.

[0041] The dust suppressant has excellent dust suppression effect and stability, has low corrosion to metals, and each component in the dust suppressant is a biodegradable component, so it has low pollution to the environment.

[0042] In another typical embodiment of the present application, a method for preparing a dust suppressant is provided, the method comprising mixing raw materials including a surfactant, a binder, a stabilizer, a wetting agent, a corrosion inhibitor and water to obtain the dust suppressant.

[0043] The preparation method of the present application is simple and has low preparation cost. The dust suppressant prepared by the above preparation method has excellent dust suppression effect and stability, low corrosion to metals, and each component in the dust suppressant is a biodegradable component, which has low pollution to the environment.

[0044] In one embodiment of the present application, the above-mentioned raw materials also include any one or more of a pH regulator, a solubility aid and a viscosity regulator; the preferred preparation method includes the following steps: step S1, adding a surfactant, an adhesive, a wetting agent and a solubility aid to water at 50 to 80°C in sequence and mixing them to obtain a mixed solution; step S2, using a pH regulator to adjust the pH value of the mixed solution to 6.5 to 7.5, and then adding a stabilizer, a corrosion inhibitor and a viscosity regulator to the solution after the pH value is adjusted in sequence and continuing to mix to obtain a dust suppressant.

[0045] The use of water in the above temperature range in step S1 helps to improve the dissolution efficiency of surfactants, adhesives, wetting agents and solubility aids in water, and the pH value of the mixed solution is controlled within the above range in step S2, which helps to make the pH value of the final dust suppressant close to neutral. In addition, the preparation method also includes filtering the solution prepared in step S2 to remove impurities and standing to release bubbles, and finally obtaining the dust suppressant.
