The invention aims to provide a preparation method of an environment-friendly air dust suppressant, and the prepared dust suppressant has low cost and cannot pollute air.
The invention adopts the technical scheme that a preparation method of an environment-friendly air dust suppressant is implemented according to the following steps:
step 1, weighing the following components for later use according to a mass ratio, wherein the components comprise 20-38% of starch, 10-15% of bentonite, 12-20% of polyvinyl alcohol, 5-10% of glycerol, 5-10% of surfactant, 2-8% of penetrating agent and 30-45% of water, and the sum of the mass percentages of the components is 100%;
step 2, adding the bentonite weighed in the step 1 into a ball mill for ball milling to obtain ball-milled bentonite;
and 3, adding the weighed starch, polyvinyl alcohol, glycerol, surfactant, penetrating agent, water and the bentonite subjected to ball milling into a wet stirrer, and uniformly stirring to obtain the air dust suppressant.
The present invention is also characterized in that,
the fineness of the bentonite after ball milling is 200-300 meshes.
The stirring temperature is 50-70 ℃.
The rotating speed of the stirrer is 800-1200 r/min.
The surfactant is an anionic surfactant.
The environment-friendly air dust suppressant has the beneficial effects that the preparation method is simple and clear, the operability is strong, the environment-friendly air dust suppressant is prepared by ball milling and stirring and mixing, all components are uniform and stable, dust in the air can be condensed and settled, no pollution is caused to the air, and the environment-friendly air dust suppressant has wide application value.
