Abstract

The invention relates to a dust suppressant for mineral powder and a preparation method of the dust suppressant. The dust suppressant is obtained by preparing a polymer hydrosol through a copolymerization technique by using an ionic monomer and a nonionic monomer as raw materials, and performing mixing on the polymer hydrosol and a silica sol. According to the dust suppressant provided by the invention, the polymer hydrosol has a low particle size and better bonding ability to the mineral powder; and the silica sol improves cohesive force of the organic polymer, and the shell layer formed by the silica sol has better weathering resistance.

Description

technical field

[0001] The invention relates to a mineral powder dust suppressant in the field of mineral powder dust control, in particular to a copolymerized blend polymer hydrosol dust suppressant and a preparation method thereof. Background technique

[0002] All kinds of pollution caused by ore crushing and mineral powder storage yards seriously threaten the safety of the atmosphere, water and human body. The inhalable particulate matter PM10 and fine particulate matter PM2.5 in the mineral powder dust are easy to enrich heavy metal ions, organic oxides, bacteria and viruses. It is extremely harmful to the human body. Therefore, it can suppress ore powder dust in the process of ore crushing, transportation and stacking, and improve the air quality of the working environment.

[0003] Starch, cellulose and their deep-processing products are natural polymer compounds with good safety, but their water resistance needs to be improved. EVA and PVA are synthetic polymer com...
