Abstract
The invention relates highly effective fireproof dust suppression material and method. The material comprises 60% calcium chloride dehydrate, 20% magnesium chloride hexahydrate, 20% water and surface active agent. The surface active agent comprises wetting agent, dispersing agent and inhibitor. The calcium chloride-dehydrate and magnesium chloride hexahydrate have hydroscopicity and fire-retardancy, and the surface active agent has the advantages of reducing surface tension, humectation and thickening action. The invention has the advantage of reducing corrosion. It can be used in anti-dust, fireproof fields.
Description
Background technology
The present invention relates in the progress of coal mining, synthesis dust prevention technology, preventing and extinguishing fire technology, the dust suppression of surface mines road surface, fields such as the fire-retardant dust suppression of harbour dump especially relate to a kind of highly effective fire-proof dust-suppressing material and synthetic method with dust suppression and fire-retardant double effects.
Background technology
At present, synthesis dust prevention technology in the coal mining, preventing and extinguishing fire technology, the dust suppression of surface mines road surface, technology such as the fire-retardant dust suppression of harbour dump, all are the cardinal tasks that are related to national individual life and property, at present, though dust-suppressing materials such as dust-adhesive fire retardant also occurred, certain effect is also arranged in the application of reality,, all exist many drawbacks, big as corrodibility, its corrosion rate reaches: 0.25mm/a～0.3mm/a, to general ferrous products, paint and leather all have serious corrosion harmfulness, this just limits its range of application greatly, and the viscosity of its binding dust is big not enough in addition, the not enough ideal of its fire-proof dust-suppressing effect, to this, also there is not good terms of settlement at present.
Summary of the invention
In order further to solve the existing problem of fire-proof dust-suppressing material, the invention provides a kind of " highly effective fire-proof dust-suppressing material and synthetic method ", this method synthetic material can reduce its corrosion rate greatly, corrosion rate can be controlled between the 0.10mm-0.15mm, can reduce to the corrosion of equipment with to environment damage, enlarged its range of application,, also can be applicable to fields such as the dust suppression on surface mines road surface and the fire-retardant dust suppression of harbour dump except being used in synthesis dust prevention, the fp field in the coal mining.Therefore it has great application value.
The technical solution adopted for the present invention to solve the technical problems is: this scheme is according to the inorganic salt Calcium dichloride dihydrate, water-absorbent that magnesium chloride hexahydrate has and flame retardant resistance and have and reduce surperficial tension, cohere to have, the thing of joining of the tensio-active agent of wetting, thickening power combines, and the fire-proof dust-suppressing material of succeeding in developing, this material it can make sedimentary coal dust effectively cohere, lose the ability of flying upward, thereby reach the effect of fire-proof dust-suppressing, and can be unnatural after the deposition, also can reduce floating dust concentration simultaneously.
Its concrete scheme is: the dust suppression fire retardant is characterized in that it is 60% Calcium dichloride dihydrate, 20% magnesium chloride hexahydrate, 20% water by content and is made up of the surfactant blend that wetting agent, dispersion agent and inhibiter are formed; The consumption of surfactant blend is 1.0% of calcium chloride, magnesium chloride and a water weight, and the proportioning of each agent is a wetting agent: dispersion agent: inhibiter=1.0: 0.2-1.0: 0.02-0.5.
The wetting agent of surfactant blend is aliphatic acid polyethenoxy ether JFC, peregal 0, polyoxyethylene octylphenol ether OP-7, OP-10, polyoxyethylene nonylphenol ether 0 π-7,0 π-10; Dispersion agent is MS-1, soap calcium dispersion agent; Etching reagent is Neovadine AN, inhibition M2, the agent of SH-2 acidizing corrosion, 581 inhibiter.
Preparation method of the present invention is: will contain Calcium dichloride dihydrate, the industrial clear liquid that magnesium chloride hexahydrate and water are formed carries out heating evaporation, and dehydration is purified; Be heated to 50 ℃-240 ℃ adding surfactant blend, and stirring, continuing dehydration, in clear liquid, contain Calcium dichloride dihydrate or magnesium chloride hexahydrate 55-80%, when water is 20-45%, finish reaction, cooling is solid-state then, under drying conditions, carry out fragmentation, screening again, control size≤0.5mm makes powder-like product, also the condensation material can be poured in the ready-formed flakey condensing works, promptly make the flakey product, perhaps powder-like product adds water and also can be ointment shape product; Also Calcium dichloride dihydrate or magnesium chloride hexahydrate clear liquid purification back condensation can be the solid-state primary fragmentation that carries out, again with surfactant blend, with organic flux methylene dichloride or acetone fusion, spray then on disposable broken material, 60 ℃-90 ℃ of reheat, behind the volatilization organic flux, carry out secondary breaking again, be the powder-like product of flux spraying process preparation; The organic flux consumption is that the compound ratio of joining thing and flux of tensio-active agent is 1.0: 1.0-10.
Its beneficial effect is: this method synthetic material can reduce its corrosion rate greatly, corrosion rate can be controlled between the 0.10mm-0.15mm, can reduce to the corrosion of equipment with to environment damage, enlarged its range of application, except being used in synthesis dust prevention, the fp field in the coal mining, also can be applicable to fields such as the dust suppression on surface mines road surface and the fire-retardant dust suppression of harbour dump, so it has great application value.
