preparation example Construction

[0055] The embodiment of the present invention also provides a method for preparing a dust suppression material, which adopts the following steps:

[0056] Step S100, the first solution and the second solution are polymerized in an environment below -5°C, and then evaporated and crystallized to obtain an adhesive, wherein the first solution is epoxy resin, silane coupling agent, cellulose and starch glue. One of the aqueous solutions, the second solution is one of the aqueous solutions of polyvinyl chloride resin, asphalt, rubber binder, and vinyl acetate; the silane coupling agent is one of KH-550, KH-580, and KH-560. kind. The mass fraction of the first solution and the second solution is (10-30): (70-90).

[0057] In step S200, the gelling material, the adhesive, the accelerator, the water reducing agent, the water retaining agent and the wetting agent are mixed uniformly to obtain a dust suppression material.

[0058] The above-mentioned dust suppression materials are no...

Embodiment 1

[0066] By weight, 75 parts of Portland cement, 20 parts of adhesive, 5 parts of sodium metaaluminate, 3 parts of polycarboxylate water reducer, 6 parts of hydroxypropyl methylcellulose ether (400,000 mPa.s), 5 parts hydroxypropyl starch ether, 32 parts wetting agent. Put them into a mixer in turn and evenly stir and mix for 3 hours to obtain a dust suppression material.

[0067] The adhesive is obtained by evaporating and crystallizing the epoxy resin and the rubber adhesive after the completion of the polymerization reaction at -11.3 °C, and the mass ratio of the epoxy resin and the rubber adhesive is 30:70.

[0068] The wetting agent is a compound of sodium dodecylbenzenesulfonate and sodium dodecyl sulfate, and the mass ratio of sodium dodecylbenzenesulfonate and sodium dodecyl sulfate is 1:1.

Abstract

The invention discloses a dust suppression material as well as a preparation method and application thereof, relates to the field of dust suppression, and aims to solve the technical problem that an existing dust suppression material in the prior art cannot meet the dust content requirement of a mine. The dust suppression material provided by the embodiment of the invention is prepared according to the following formula: the formula at least comprises the following components in parts by weight: 60-90 parts of a cementing material; 18 to 35 parts of an adhesive; 1 to 8 parts of an accelerator; 2-5 parts of a water reducing agent; 8 to 15 parts of a water-retaining agent; 21 to 43 parts of a wetting agent; the cementing material is a combination of one or more of sulphoaluminate cement, Portland cement and aluminoferrite cement in any proportion; the accelerator is sodium metaaluminate; the water reducing agent is a polycarboxylic acid water reducing agent; the wetting agent is a surfactant. The dust suppression material is used for treating mine coal dust.

Description

technical field [0001] The present disclosure relates to the field of dust suppression, and in particular, to a dust suppression material and a preparation method and application thereof. Background technique [0002] China is rich in coal resources, and disasters occur frequently in the process of coal mining, especially gas disasters are often accompanied by coal dust explosions. A large amount of coal dust will also cause front-line workers to suffer from various diseases. At the same time, intelligent mining requires dust control and dust removal, which makes dust suppression not only related to life safety, but also has great economic benefits. [0003] Traditional dust removal methods include coal seam water injection, spray dust removal, dust collector dust removal and foam dust removal, etc., which are not ideal in suppressing anthracite coal dust. The use of chemical dust suppression can avoid the above problems. The existing dust suppressants mainly include wettin...
