Problems solved by technology

At present, dust prevention methods mainly include spraying water for dust reduction and dust removal by dust collectors, etc., but these methods have obvious limitations. Spray and water sprinkler dust reduction are only temporary. Once the air is dry, the dust on the ground will rise again; Only for local areas, not suitable for large area dust removal

Embodiment Construction

[0016] The invention is mainly used to prevent dust in various construction sites, road construction, landfill sites, ash storage pools, army campsites, mining, toxic and dangerous sites, etc., and plays the role of dust suppression and air purification.

[0017] Mix and heat deionized water, acrylic acid, methyl methacrylate, acrylamide and cross-linking agent, keep stirring, add initiator when heated to 65-75°C, react for 30-60 minutes, add neutralizer after cooling Adjust to neutral to obtain the dust preventive agent. The distribution ratio of each group is:

[0018] 100-120 parts by weight of deionized water: 100 or 120 parts can be used; 7-12 parts by weight of acrylic acid: 7 or 12 parts can be used; or 2-4 parts by weight of methyl methacrylate: 2 or 4 parts; add acrylamide 2-4 parts by weight: 2 or 4 parts; crosslinking agent 0.03-0.05 parts by weight, 0.03 or 0.05 parts; initiator 0.05-0.1 parts by weight: 0.05 or 0.1 parts by weight; neutralizer (typical Such as s...

Abstract

The invention discloses a dust preventing agent, which includes components of water or deionized water, acrylic acid, methacrylate, acrylamide and initiator, wherein proportion of each component is: 90-120 quotient of water or deionized water; 7-12 quotient of acrylic acid or 2-4 quotient of methyl methacrylate, ethyl methacrylate or propyl methacrylate; 2-4 quotient of acrylamide; 0.05-0.1 quotient of persulfate initiator; 0.03-0.05 quotient of crosslinking agent and 5-10 quotient of neutralizer which are also added. The dust preventing agent is thick liquid and is used after diluting, when being sprayed, the dust preventing agent can adsorb dust in air and combine with granule on ground surface to form film structure, and the dust preventing agent also possesses water-absorbing quality and water-retention property to prevent dust flying and clean air.

Description

technical field [0001] The invention belongs to the field of organic dust removers, in particular to an organic chemical dust preventer and a preparation method thereof. Background technique [0002] Urban construction, various construction sites, mining, road construction, landfill, industrial ash storage, etc. will produce a large amount of dust, these dust particles are easily lifted by the wind and float in the air, causing air pollution and various diseases , seriously affecting people's quality of life and physical and mental health, so effective measures must be taken to control it. At present, dust prevention methods mainly include spraying water for dust reduction and dust removal by dust collectors, etc., but these methods have obvious limitations. Spray and water sprinkler dust reduction are only temporary. Once the air is dry, the dust on the ground will rise again; It is only used in local areas, not suitable for large-scale dust rem...
