摘要: 为解决污水中的油品污染问题,采用悬浮聚合后经冻胶纺丝制得的甲基丙烯酸酯共聚吸附功能纤维与涤纶和丙纶短纤按一定比例混合(分为夹层和共混两种方式)后,两边用聚丙纶纺粘非织造布夹裹,针刺加固,制备出一种低价、高效的新型复合针刺材料。对甲基丙烯酸酯共聚吸附功能纤维进行吸附性能与力学性能测试,选取最佳配比方案的纤维进行下一步针刺复合材料制备。研究了复合针刺吸附材料对煤油、甲苯和三氯乙烯的吸附速率、饱和吸油率及保油率,讨论了混合方式不同对其吸附性及保油率的影响,并进一步从环保方面考虑测试复合针刺材料对油品吸附的重复利用率。 实验结果表明:甲基丙烯酸酯共聚吸附功能纤维质量配比为(MBMA/MHEMA /MAN) 75/15/10时,纤维的性能较复合针刺材料的制备。丙纶夹层复合针刺材料的吸油速率、饱和吸油率及保油率优于其它三种;以丙纶夹层复合针刺材料进行重复利用率的实验,吸附-脱附过程中脱附量基本可以达到90%以上,吸附量略有减少,基本保持平衡,满足重复利用的要求。

Abstract: In order to solve the oil pollution,the methyl acrylate absorbing fiber which was obtained by suspension polymerization through gel spinning was wraped with polyester and polypropylene respectively (blending and sandwich).Both sides were covered with polyethylene spunbond nonwoven fabric and then needled reinforcement.This prepared a low-cost and highly efficient compositing needled materials.We researched the absorption and mechanical properties of the methl acrylate functional fiber. Finally,the best ratio program was selected to the compositing needled materials. We studied the absorption rate,saturated oil absorption and protecting oil rate of kerosene,toluene and trichloroethylene.We discussed the influence of absorption and protecting the oil rate for different mixed ways,and considered the reuse of compositing needled materials from the environmental applications .The results showed that:when the mass ration (MBMA/MHEMA/MAN)of methyl acrylate function fiber was 75/15/10,the performance of methyl acrylate function fiber was better to compositing needled materials.The oil absorption rate,saturated oil absorption and protecting oil rate to laminated polypropylene materials were superior to others. Laminated polypropylene materials were tested to the reuse experiments.The desorption amount of absorption-desorption was up to 90%.The absorption was decreased slightly and meeted the reuse requirments.
