Description
技术领域
本发明是输油管道减阻的减阻聚合物油基分散方法,涉及高分子化合物的组合物和管道系统领域。
背景技术
减阻聚合物通常采用α-烯怪超高分子量聚合物。但采用本体聚合法得到的α-烯烃超高分子量聚合物为粘弹牲块状,不能直接用于输油管道,只有经过深冷破碎为粉状颗粒并经液体溶剂溶解或分散后才能使用。目前采用普遍且较好的分散方法中就有很多种,其中我公司于2003年4月10日申清的“α-烯烃-苯乙烯超高分子量共聚物悬浮分散方法”(申请号03109630.1)中发明的溶纤剂一直链醇分散技术,采用溶纤剂代替水来调整分散系统的密度,避免了水的溶涨作用,大大改善了悬浮分散京统的稳定性,使有效咸分含量高,抗低温性能优异,但不足是抗高温性能仍然较差,在夏享及高温地区仍然难以使用。
发明内容
本发明的目的是发明一种固含量高、粘度低、提高悬浮分散系统高温性能和悬浮稳定性的减阻聚合物油基分散方法。
本发明虽然也采用在新粉碎的减阻聚合物中加入分散剂进行搅拌的方法,但其特点是采用了新的分散剂和新的工艺方法,就是在植物油中添加少量紫外线吸收剂和杀菌剂混合均匀作为分散剂,加入隔离剂的减阻聚合物低温粉碎后的粉末加入分散剂中搅拌,待均匀后即成。具体是将占总重量50-90%的植物油中添加0.001-0.1%的紫外线吸收剂和0.001-0.1%的杀菌剂混合均匀,占总重量10-40%的α-烯烃-苯乙烯超高分子量共聚物的减阻聚合物加入2-25%的隔离剂,在低于-90℃的温度条件下破碎成粉末,加入分散剂中用高速乳化机进行搅拌,使之均匀并乳化。其中的隔离剂为硬脂酸镁、硬脂酸钙、硬脂酸锌、硬脂酸、聚乙烯腊聚氯乙烯糊、活性白土、活性硅藻土、活性碳酸钙、活性白炭黑或它们的混合物。植物油是花生油、大豆油、玉米油、葵花籽油、菜籽油、棉籽油、棕榈油、橄榄油、胡麻油、芝麻油或它们的混合物。紫外线吸收剂是UV-9、UV-531、UV-326或它们的混合物。杀菌剂为WT-307B杀菌灭藻剂(二硫氰基甲烷)。为了改善分散系统的外观,还可在分散剂中加入占总重量0.001-0.01%的着色剂,该着色剂为亚甲蓝。
本发明采用植物油作分散剂,添加少量紫外线吸收剂防止减阻聚合物降解,添加少量杀菌剂防止植物油变质,添加少量着色剂改善分散系统的外观,而植物油的耐高温性能好的特点就可充分发挥。本方法中由于采用了隔离剂对减阻聚合物粉末的密度和植物油的密度进行了调整,虽然仍有一定的差别,但己很小,特别是由于用本方法所制得的油基悬浮分散系统粘度较大(与溶纤剂-直链醇分散系统相比),并且分散剂与分散质的密度非常接近,分层现象并不明显,可以稳定保持六个月,六个月后即便有少量分层也并不影响现场用。
具体实施方式
以卞面两个实施例说明本发明的具体实施方式。
实施例1.称取大豆油620kg,UV-9紫外线吸收剂0.1kg,杀菌剂二硫氰基甲烷0.001kg,置于2m3搅拌罐中,搅拌均匀,将320kg的α-烯烃-苯乙烯超高分子量共聚物和60kg的硬脂酸钙隔离剂在-90℃条件下破碎成粉末后加入分散剂中,启动搅拌罐中的高速乳化机再次搅拌均匀,得到聚合物固含量为32%的蓝色悬浮分散系统。该悬浮分散系统可以稳定放置六个月,闪点为115℃,其粘度与温度的关系为:
温度/℃ 10 20 30 40 50 60 70 80
粘度/pa.s 0.422 0.363 0.308 0.326 0.376 0.435 0.636 0.948
实施例2.称取玉米油670kg,UV-531紫外线吸收剂0.1kg,二硫氰基甲烷杀菌剂0.1g,亚甲蓝着色剂0.001kg,置于2m3搅拌罐中搅拌均匀,将280kg的α-烯烃-苯乙烯超高分子量共聚物和活性碳酸钙隔离剂50kg在-92℃条件下破碎成粉末,加入搅拌罐里的分散剂中,启动高速乳化机再次搅拌均匀,得到固含量为32%的蓝色悬浮分散系统。该悬浮分散系统可以稳定放置六个月,闪点为118,其粘度与温度的关系为:
温度/℃ 10 20 30 40 50 60 70 80
粘度/pa.s 0.450 0.425 0.389 0.459 0.509 0.620 0.785 1.104
本方法在保证悬浮分散系统流动性能即粘度低的前提下,固含量高,可以达到35%;提高了减阻聚合物悬浮分散系统的耐高温性能,其使用范围可10-70℃;闪点大于107℃,大大增大了悬浮分散系统的闪点,提高了减阻聚合物悬浮分散系统运输及贮存的安全性能;消除了醇基悬浮分散系统的气味,改善了操作环境;稳定性好,可稳定放置六个月以上。本方法所制得的减阻聚合物油基悬浮分散系统与已有的溶纤剂-直链分散系统可以相互补充,分别应用于高温和低温环境。
