Abstract

The present study, based on copolymerization of free radicals, makes hydroxyethyl cellulose react with acrylamide and acrylic acid to prepare a type of agglomeration-cementing dust suppressant with decent fluidity, agglomeration ability and water absorption capacity. Single-factor experiments are carried out to determine the optimal reaction conditions; the progress of the reaction was analyzed using FTIR and XRD; TG-DSC and SEM are used to further characterize the product; special experiments are designed to test the product’s viscosity, wettability mechanical properties, wind resistance and water resistance. The experimental results indicate that the newly developed agglomeration-cementing dust suppressant is favored due to the easiness to apply in the field and its decent ability to withstand wind and rain.
