Abstract
The invention provides a dust nuisance depressor and its production method, whose constituents include polyvinyl alcohol, polyacrylamide, 707 glue and water. Its production process consists of dissolving polyvinyl alcohol, making polyacrylamide dispersion solution, loading the mixed solution into a heat preservation still, charging 707 glue, and agitating homogeneously. The protective film formed by spraying the suppressing agent has good strength, tenacity, light resistance and water resistance.
Description
Technical field
The present invention relates to a kind of chemicals and production method that is used for environmental protection, particularly suppress the preparation and the production method thereof of airborne dust.
Background technology
The main source of dust pollution is an airborne dust, battle field, Tu Chang in the construction site, and all there are serious airborne dust and raw material oneself loss problem in the coal yard of enterprise, ash field and raw material, breeze, cindery accumulation place.In the prior art, general employing regularly water spray is handled, because moisture evaporation is fast, and sprinkling frequency height, labour intensity is big, a large amount of waste water resources, but airborne dust suppresses DeGrain.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of preparation and production method thereof that can effectively suppress airborne dust is provided.
Purpose of the present invention realizes by following measure: the weight ratio of Fugitive dust inhibiting agent moiety is:
Polyvinyl alcohol 4-5 polyacrylamide 8-12 707 glue 4-6 water 80-92
The production method of Fugitive dust inhibiting agent may further comprise the steps:
1, with being equipped with the water yield 1/3 put into reactor heating, temperature remains on 85-95 ℃, puts into polyvinyl alcohol then, is stirred to whole dissolvings.
2, with remainder water polyethylene acyl ammonia is soaked into, mixing and stirring is made dispersion liquid with the emulsification pretreatment pump then.
3, polyethylene acyl ammonia dispersion liquid is put into reactor by the emulsification pretreatment pump, stir.
4, the mixed solution of polyvinyl alcohol and polyacrylamide dispersion liquid is put into the insulation still by the emulsification pretreatment pump, add 707 glue.
5, above-mentioned mixed solution is stirred in the insulation still, promptly get the Fugitive dust inhibiting agent product.
This Fugitive dust inhibiting agent is after dilution; be sprayed at the stores surface of required dust suppression; form the impermeable protective membrane of one deck; this protective membrane has intensity and toughness preferably; have fast light preferably property, the water tolerance of shining; suffer wind, Exposure to Sunlight, drench with rain, the superperformance that keeps continuous whole to cover for a long time.This product cost is low, and result of use is good.
Embodiment
Embodiment 1: the weight ratio of Fugitive dust inhibiting agent moiety is:
Polyvinyl alcohol 4.5 polyacrylamides 10 707 glue 6 water 80
The production method of Fugitive dust inhibiting agent may further comprise the steps:
1, with being equipped with the water yield 1/3 put into reactor heating, temperature remains on 85-95 ℃, puts into polyvinyl alcohol then, is stirred to whole dissolvings.
2, with remainder water polyethylene acyl ammonia is soaked into, mixing and stirring is made dispersion liquid with the emulsification pretreatment pump then.
3, polyethylene acyl ammonia dispersion liquid is put into reactor by the emulsification pretreatment pump, stir.
4, the mixed solution of polyvinyl alcohol and polyacrylamide dispersion liquid is put into the insulation still by the emulsification pretreatment pump, add 707 glue.
5, in the insulation still, stir, promptly get the Fugitive dust inhibiting agent product.
Claims (2)
1, a kind of Fugitive dust inhibiting agent is characterized in that the weight ratio of its moiety is:
