Abstract:

In this article, a kind of synthetic polymer dust suppressants agent was prepared with poly (vinyl- alcohol) (PVA), carboxymethylcellulose (CMC) and acrylamide (AM). The chemical and physical properties of this dust suppressant was characterized by means of grafting rate, FT-IR analysis, TG test, viscosity analysis and SEM survey. The result showed that grafting rate was reached 95.6%; IR spectrum proved that monomers have been completely reacted basically; thermal gravimetric analysis was characterized that the dust suppressant has good thermal stability between 0°C-250°C; the amount of AM and SDBS were 50% and 1.0% (based on mass of the total materials), the polymer has a suitable viscosity; SEM was used to observe the shape characteristic of the coal dust which formed a link between the dust suppressant and coal dust. The water resistance of the dust suppressant was well in 24h.
