【 摘 要 】

In this paper, the cationic monomer was grafted into the dust suppressant molecule innovatively. The dust particles were adsorbed through net capture function, and the dust suppression efficiency was improved by charge interaction for dust particles' electronegative. This experiment adopted the starch, acrylic acid and methacryloyloxyethyl trimethyl ammonium chloride (DMC) as raw materials, with potassium persulfate as initiator and glycerol as the crosslinking agent, synthesizing a new type of water-absorbent resin dust suppressant with cation (later called CNDS). After structure characterization and performance test, the results showed that the cationic monomer were successfully grafted and the CNDS had good functions of keeping moisture, wind-resistant, compressive resistance and anti-erosion. The viscosity of CNDS solution (2%) is 24.7 cP, which can bond and adsorb the dust particles in the air effectively. According to economic cost accounting, spraying CNDS only costs 0.46 yuan per square meter. Hence, there is a great prospect of promotion and application due to its low price.
