摘要:
影响聚 α-烯烃减阻剂悬浮液稳定性的主要因素包括：载体介质的极性和密度，分散剂的种类、用量和处理方法，聚 α-烯烃粉末颗粒的尺寸等。基于此，对聚 α-烯烃减阻剂悬浮液的配方和工艺进
行优化：碳数适中的戊醇与乙二醇甲醚按一定比例混合，作为载体介质，有利于聚 α-烯烃在其中的稳定分散与悬浮；硬脂酸镁作为分散剂，可以改善载体介质与聚 α-烯烃粉末颗粒的界面属性，经 45 ℃热处理，能够有效减缓聚 α-烯烃颗粒的沉降和分层；聚 α-烯烃粉末颗粒的尺寸越小，相同质量的聚α-烯烃的表面积越大，配制的减阻剂悬浮液稳定性也越好。因此，减阻剂最终产品可在常温下储存270 d 不分层、不结块，稳定性能良好。
Abstract:
Main factors to influence the stability of poly-α-olefin drag reduction agent suspension system include the polarity and density of carrier medium，types，quantity and treatment methods of dispersants and particle size of poly-α-olefin，etc. Therefore， the optimization of formulation and technique for poly-α-olefin drag reduction agent suspension are carried out. Pentanol of moderate carbon number mixed with ethylene glycol monomethyl ether at a special ratio is used as carrier medium，which benefits to stable dispersion and suspension for poly-α-olefin. The magnesium stearate as dispersant could improve superficial property of carrier medium and poly-α-olefin particle. And with 45℃ heat treatment，deposition and delamination of poly-α-olefin particle are effectively decreased. When the particle size of poly-α-olefin is smaller and the surface area with same quantity is higher，the better stability of suspension is obtained. The drag reduction agent prepared shows good stability at room temperature for 270 days without bedding and agglomerating phenomena.
