摘　　要：为解决矿山开采与运输过程中所产生的扬尘问题,采用接枝共聚的方法,以羧甲基纤维素钠和丙烯酰胺为反应底物,加引发剂、交联剂以及辅助成膜剂合成高分子聚合物。优化合成工艺后以此作为抑尘剂主体,再复配以木质素磺酸钠和丙三醇加强润湿、保湿效果,最后对抑尘剂进行结构表征、性能检测和现场实验。结果表明,优化后的合成工艺条件为反应温度65℃、反应时间5.5h、KSP和MBA的添加量分别为单体质量分数的1.2%、0.6%;木质素磺酸钠和丙三醇的最优添加量分别为抑尘剂质量分数的0.8%和1%;此抑尘剂的抑尘效果相较于洒水抑尘的保湿时间延长3~4h,润湿性能增强2倍以上,抑尘率提升45%且经现场实验验证抑尘率提升89%。In order to solve the dust problem generated from mining and transportation of mines,we developed a graft copolymerization method to synthesize a high polymer using sodium carboxymethyl cellulose and acrylamide as reaction substrates,and the initiators,crosslinkers,and auxiliary film-forming agents were added.After optimizing the synthesis process,this polymer was used as the main components of dust suppressants.The sodium lignosulfonate and propanetriol were also added to improve the wettability and moisturizing performance of the dust suppressants.The structural characterization,performance tests and field experiment results show that the optimized reaction temperature and reaction time for the synthesis process are 65℃and 5.5h,respectively,and the added amounts of the KSP and MBA are 1.2%and 0.6%of monomer by weight,respectively.The optimal addition amounts of sodium lignosulfonate and glycerol are 0.8%and 1%of dust suppressants by weight.Compared with the sprinkling as a dust reduction method,the moisturizing time of using dust suppressants as a dust reduction method was increased by 3~4h and the wettability is more than twice higher.The dust suppression rate was increased by 45%.Moreover,the dust suppression rate was increased by 89%,which was verified by a field experiment.
