Description
技术领域
本发明涉及高性能吸油纤维制备领域，具体是一种高持油性聚苯硫醚纤维的制备方法。
背景技术
在石油开采、运输及加工过程中产生了大量的含油废水，处理非常困难，若直接排放会极大地污染生态环境，也会造成石油资源的浪费。石油废水包括两种，油水分层液和油水乳化液，针对两种不同的油水混合物，研究人员开发出了多种处理模式，其中主要以吸油材料和超亲/疏水分离材料应用最广。采用疏水化纤制备的吸油毡已普遍应用于治理海上石油泄漏、钻井平台石油废水处理等领域。但目前存在的吸油毡大多存在耐油溶剂性差导致的重复使用性不佳，持油性差及吸油量低等缺陷。
聚苯硫醚(PPS)材料是半结晶性工程塑料，通过熔融纺丝-拉伸-卷曲过程制备的PPS纤维是一种高性能纤维，具有很强的热稳定性能，其长期使用温度在200℃，短期可经受260℃不变性；具有较强的耐化学腐蚀性，如强酸强碱，但不耐氧化性酸，如硝酸、硫酸、氯磺酸等；耐溶剂性较强，通常认为在200℃下没有溶剂能将其溶解。综上所述，PPS纤维具有较强的极端环境下应用的潜能。石油是多种有机物的混合物，具有溶剂特性，因此吸油材料需要有一定的耐溶剂性，将PPS纤维制备吸油毡已广泛应用于含油废水处理领域，但纤维表面光滑，油迹不能对纤维表面进行包覆，容易形成串珠状油迹，导致吸油能力、持油能力差问题严重影响吸油效率。
发明内容
针对现有技术的不足，本发明拟解决的技术问题是，提供一种高持油性聚苯硫醚纤维的制备方法。
本发明解决所述技术问题的技术方案是，提供一种高持油性聚苯硫醚纤维的制备方法，该技术包括如下步骤：
1)将复配溶剂、PPS粉料树脂、疏水改性剂均匀混合，升温至250-260℃，得到均相改性溶液，随后降温至210-225℃并保持；复配溶剂、PPS树脂、疏水改性剂的质量之和为100％，复配溶剂占总质量的85.0-99.9％，PPS粉料树脂占总质量的0.1-10.0％，疏水改性剂占总质量的0-5.0％；所述复配溶剂包含良性溶剂和劣性溶剂，两者缺一不可，良性溶剂和劣性溶剂的质量比为1:1-9:1；所述良性溶剂包括二苯甲酮、安息香、己内酰胺、二苯砜、1-氯萘、二苯醚中的至少一种；所述劣性溶剂包括邻苯二甲酸二丁酯、癸二酸二丁酯、邻苯二甲酸二辛脂、癸二酸二辛脂、间苯二甲酸二丁酯、间苯二甲酸二辛脂、丙三醇中的至少一种；
2)将PPS纤维在烘箱中热处理一定时间后迅速浸没在上述溶液中，持续一定时间后倒入凝固浴中冷却；所述凝固浴为水、卤代烃类溶剂、醇类溶剂、酯类溶剂、醚类溶剂、酰胺类溶剂或烃类溶剂中的至少一种；
3)经过溶剂萃取、烘箱干燥、开松、除杂、喷洒助剂、梳理操作，将多余的改性剂去除，粘连纤维分离，得到均匀疏松且无多余杂质的改性高持油PPS纤维；所述萃取溶剂为卤代烃类溶剂、醇类溶剂、酯类溶剂、醚类溶剂、酰胺类溶剂或烃类溶剂中的至少一种；所述助剂为化纤油剂，如平滑剂、乳化剂、抗静电剂中的至少一种。
本发明还涉及保护上述的制备方法得到的高持油性聚苯硫醚纤维。
与现有技术相比，本发明有益效果在于：
(1)本发明通过热致相分离(TIPS)过程控制纤维表面异形结构生成，通过良性溶剂和劣性溶剂复配在高温下将PPS粉体树脂溶解，得到均相PPS溶液。当体系降至一定温度下，PPS短纤在该体系中，表面树脂发生微溶解分子链舒展，形成富聚合物区域，引起周围PPS分子浓度升高形成分相趋势。而劣性溶剂调节分子运动态势促使分相趋向液-液(L-L)分相，而由于PPS浓度过低造成粗化过程受抑制，形成超细PPS纤维网结构。
(2)超细PPS纤维网结构在PPS纤维表面组成同质皮芯纤维结构，该结构稳定，除机械力等外力可抵抗任何作用。纤维网皮层有利于提高表面粗糙度，提高疏水性，在油包水型油水混合物的处理等领域有极大的应用潜力。同时纤维网络结构皮层具有超强的油润湿性和表面延展性，能进一步提高纤维持油性，能极大提升吸油毡/纸等材料的油水混合物处理能力。
(3)疏水性纳米材料如rGO、MWCNTs等引入均相溶液中有效调节分相过程，促使表面纤维网层、凸起结构、树枝状结构等异形结构生成，且皮层结构加厚，进一步提高疏水性和持油性。
