泡沫型吸油复合材料的制备及其吸油性

Preparation of foaming composites and their oil absorption capacity

为解决污水中的油类污染问题,采用环保无毒的三元乙丙橡胶(EPDM)作为基体,金矿提纯后的废弃矿渣粉作为填料,利用熔融共混及模压发泡的方法,制备出一种低价、高效的泡沫型吸油复合材料(废弃矿渣粉/EPDM).研究了填料、交联剂(DCP)和发泡剂(AC)的用量对复合材料吸油率的影响,讨论了相应复合材料的保油率,并从EPDM自身结构、交联剂DCP及废弃矿渣粉的添加量等方面对复合材料的吸油机理进行了分析.实验结果表明:废弃矿渣粉含量为10phr,DCP含量为2phr,AC含量为4phr是复合材料的最佳配比.非泡沫型复合材料的吸油率比交联EPDM的吸油率提高了101.46%;泡沫型复合材料比非泡沫型复合材料的吸油率再次提高389.82%.

In order to solve the problem of oil pollution in wastewater,a new kind of foaming material for oil adsorption was prepared by melting blend and mold pressing,with EPDM as the matrix and waste dusty slag as the filler. The effects of DCP,foaming agent （AC） and waste dusty slag contents on the oil absorbency were studied. Results show that the material reaches the highest oil absorbency under conditions of 10 phr waste dusty slag loading,2 phr DCP loading,and 4 phr AC loading. The oil absorbency of non-foaming composite is 101.46% more than that of EPDM （crosslinked）,and the oil absorbency of foaming composite is 389.82% more than that of non-foaming composite.
