Embodiment 1

[0013] Embodiment 1: the weight ratio of dust suppressant composition is:

[0014] Polyvinyl alcohol 4.5 polyacrylamide 10 707 glue 6 water 80

[0015] The production method of dust inhibitor comprises the following steps:

[0016] 1. Put 1 / 3 of the prepared water into the reactor to heat, keep the temperature at 85-95°C, then put in polyvinyl alcohol, and stir until completely dissolved.

[0017] 2. Soak the polyvinylamide with the remaining water, mix and stir evenly, and then use a shear emulsification pump to make a dispersion.

[0018] 3. Put the polyvinylamide dispersion into the reaction kettle through the shear emulsification pump, and stir evenly.

[0019] 4. Put the mixture of polyvinyl alcohol and polyacrylamide dispersion liquid into the insulation kettle through the shear emulsification pump, and add 707 glue.

[0020] 5. Stir evenly in the heat preservation kettle to obtain the dust inhibitor product.

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 [0001] The invention relates to a chemical preparation and a production method for environmental protection, in particular to a dust-suppressing preparation and a production method thereof. Background technique [0002] The main source of dust pollution is dust. There are serious problems of dust and self-depletion of raw materials in the sand and soil yards of construction sites, coal yards, ash yards, and accumulations of raw materials, mineral powder, and ash. In the prior art, regular water spraying is generally used. Due to fast evaporation of water, high spraying frequency and high labor intensity, a lot of water resources are wasted, but the dust suppression effect is not obvious. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a preparation that can effectively suppress dust and a production method thereof. [0004] The object of the present invention is achieved by the foll...
