摘　　要：以聚丙烯酰胺(PAM)和高分子吸水性树脂(SAP)为原料,制备了新型的高分子凝胶水系灭火剂,并测试了所制备的灭火剂的吸水倍率、保水率、抗酸碱、黏度及灭火性能。研究发现:SAP的粒径为30~60目,m(PAM)∶m(SAP)为1∶1.2时,灭火剂的吸水倍率为78.9 g·g^(-1),运动黏度为997.1 mm^(2)/s,灭火剂的灭火性能最好,可以节约50%的水,且没有复燃。Polyacrylamide(PAM)and polymer absorbent resin(SAP)with different particle sizes are used as raw materials to prepare a new polymer gel water system fire extinguishing agent.The water retention rate,acid and alkali resistance,viscosity and fire extinguishing performance of the prepared fire extinguishing agent are tested.The experimental results show that when the particle size of polymer absorbent resin(SAP)is 30~60 mesh,the ratio of polyacrylamide(PAM)to polymer absorbent resin(SAP)is 1∶1.2,the water absorption ratio of the fire extinguishing agent is 78.9 g·g^(-1),and the kinematic viscosity is 997.1 mm^(2)/s,the fire extinguishing performance of the fire extinguishing agent is the best,which can save 50%water and has no reignition.
