Oily dust preventive composition, preparation method and purpose for preventing dust from flying

Abstract

The invention provides an oily liquid and oil state dust preventive composition, a preparation method and purpose for preventing dust from flying. The dust preventive composition comprises the following components per 100 parts by weigh of oily solution: 50-80 parts by weight of oily liquid acrylamide copolymerized high-molecules prepared by copolymerization of acrylamide monomers, and 2.0-10.0 parts by weight of surfactant with emulsification and dispersion functions, and 5.0-30.0 parts by weight of hygroscopic oil with dispersion and moisture evaporation inhibition function, and 0.2-10.0 parts by weight of one or two kinds of natural high-molecules with good dust adhesion strength or adhesion maintenance force. In the yellow sand region, tunnel, subway, mine, coal storage field, sand storage field, road and building sit with many dust, and a certain amount of dust composition can be diluted and stirred in water for sprinkling, because of differences of adsorption, viscosity, density and polarity, after the composition is coated on flying dust surface, the dust, the granular form dust and fine dust and other dusts can be prevented from flying.

Description

technical field [0001] The present invention generally relates to a dust-proof composition, a preparation method and its application for preventing dust from flying, and specifically relates to dust, An oily anti-dust agent composition for dust such as granular dust and fine dust, a preparation method, and use of the anti-dust agent composition for preventing dust from flying. Background technique [0002] Smaller substances scattered in the atmosphere are called blown dust, and their shapes include, for example, dust, granular and fine dust. Substances scattered in the atmosphere are generated in yellow sand, desert sand, metal friction, exhaust, yellow sand, construction and civil engineering site dust, etc. Also discharged from concrete or coal, main material, etc. Such dust, granular and fine dust float in the air, attach to the leaves of plants, block the stomata of the leaves, block the sun, hinder assimilation, respiration and transpiration, etc. To affect, and, th...

Problems solved by technology

[0003] As a solution to fine dust, there are known dust extractors and other devices that inhale and purify dust, but they are expensive to use and have limited space. In addition, industrial fans (fans) perform forced ventilation. In this case, separate Disposal of dust leaked to the outside, resulting in secondary pollution

[0004] The method with the lowest cost is spraying or water sprinkling. However, when the temperature is low, it freezes after spraying, which increases the risk of injury to the operator. When the temperature is high, continuous spraying is required due to rapid evaporation. , cannot completely cover the dust, the combination of the dusty processing object (processing object) and water will lead to secondary pollution of water pollution caused by the sprayed wastewater

[0005] As an example of the above-mentioned dustproof agent, it is mixed with magnesium chloride and water in the dust construction method for suppressing flying dust on unpacked ground and the dust suppressant (Korean Patent No. 10-0494538) and then sprayed multiple times. Magnesium chloride has various hydrates Structure, ionizes when mixed, and, if used in excess, increases soil salinity, retards plant growth, and causes soil acidification

In addition, the method of using polyvinyl alcohol and LAS-type and lauryl-type anionic surfactants is disclosed in the dust scattering preventive agent (Korean Patent No. 10-0853828), but the water-solubility of the aqueous solution of polyvinyl alcohol is used. It needs to be heated to 60°C to 70°C for the reaction. According to the difference in the degree of polymerization of polyvinyl alcohol, the solubility difference is large, and if anionic surfactant is used, large foam will be generated before and after the reaction, and the construction is more difficult. The foam sometimes prevents polar flying dust from adhering to the coating with polyvinyl alcohol
