[0005] Patent CN107828378A discloses a compound dust inhibitor and its preparation method, which is made of raw materials such as urease preparation, sodium alginate, urea, calcium chloride, magnesia, tetraethyl orthosilicate, ferric iron tetroxide powder, etc. The invention inhibitor adopts a granular structure, the outer layer is coated with urease preparation, and the urease is isolated from the internal components by modified sodium alginate. When used, it is diluted and dissolved in water. Urease accelerates the hydrolysis of urea and calcium chloride to generate calcium carbonate. The cohesive properties bond the dust particles together to form large particles. At the same time, through the large-area adsorption of the modified magnesia, the rapid and efficient suppression of dust is effectively guaranteed. Compared with traditional dust suppressants, the dust suppression effect and use cost are greatly improved. The raw material cost of dust agent is high, and the production process is complicated, so it is impossible to carry out large-scale promotion

Abstract

The invention relates to an environment-friendly water-soluble adhesive dust inhibitor and a preparation method thereof. The environment-friendly water-soluble adhesive dust inhibitor comprises the following components in percentage by weight: 0.1-2% of sodium lactate, 0.1-6% of a pregelatinized starch, 2-10% of glycerinum, 0.1-5% of an adhesive, 1-5% of urea, 0.2-2% of a polyacrylic resin, 0.1-1%of a surfactant, 0.1-3% of an emulsion, 0.02-0.5% of texanol, 0.1-2% of an environment-friendly pigment and the balance of water, and the inhibitor is finally prepared through stirring and mixing. Compared with the prior art, the inhibitor is applied to dust inhibition and the like in exposed fields such as mine tailing ponds, city exposed grounds, municipal construction, coal transportation andstorage yards, is not limited by use fields, and is capable of reducing environment pollution and reducing resource waste.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environmentally friendly water-soluble adhesive dust suppressant and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, people's attention to the environment is also increasing day by day. As the number and scale of urban construction projects continue to increase, dust pollution will inevitably occur. Due to the small particle size of these dusts, they will be brought up by the action of wind and the movement of vehicles to become dust. Judging from the current environmental situation, the problem of environmental pollution caused by flying dust in our country is relatively serious, which has aroused strong reactions from the society. [0003] Since the 1920s, western countries have begun to use the simplest dust suppressant to reduce coal dust in mines. Since...
