聚丙烯酰胺的反相乳液聚合及其絮凝效果研究

摘要采用反相乳液聚合技术进行了聚丙烯酰胺（PAM）合成。以PAM特性黏数、煤泥水絮凝后上层清液透光率为指标，考察了反应影响因素，得出此方法合成PAM的最适宜工艺条件为：引发剂用量0.1%（占单体质量百分数），单体水溶液质量分数26%~29%，反应温度35 ℃，脲添加量（质量分数）5%，V(油)/V(水)为1.5。在此条件下合成的PAM特性黏数可达1 400 mL/g，上层清液透光率为95%，此工艺条件下的合成的PAM对煤泥水的絮凝效果较好。

Abstract： Polyacrylamide (PAM) was synthesized by using reverse phase emulsion polymerization. The effects of reaction conditions on the limiting viscosity number of PAM and the water light transmittance of flocculated coal slurry were studied. The optimum reaction conditions were determined by experiments as follows: the dosage of initiator 0.1%, the content of monomer 26%—29%, reaction temperature 35 ℃, the content of accessory ingredient carbamide 5%, the volume ratio of oil to water 1.5∶1. Under such reaction conditions, the limiting viscosity number of PAM was 1 400 mL/g, the light transmittance of flocculated coal slurry reached 95%, which showed the PAM had very well flocculation functions.
