高吸油性树脂的合成和应用 总被引:19,自引:0,他引:19
本文叙述了高吸油性树脂的合成和应用方面的最新发展,介绍了六种现有的合成方法,简要说明其结构特点以及吸油特性。六种合成方法包括:单烯—双烯化学交联,溶剂致孔的单烯—双烯化学交联,官能团化学交联,辐射化学交联,聚氨酯泡沫,复合材料。高吸油性树脂的结构特点是:高分子之间形成一种三维的交联网状结构,材料内部具有一定微孔结构。由于树脂分子内的亲油基链段和油分子的溶剂化作用,高吸油性树脂发生膨润。吸油过程由分子扩散控制和Flory-Huggins方程控制两部分组成。适度交联,适当减小粒径可提高树脂的吸油速度。介绍了高吸油性树脂在三废处理、芳香剂、杀虫剂、诱鱼剂基材,纸张添加剂、渔网防污剂基材,合成树脂的改性添加剂等方面的应用 相似文献

正一、项目简介采用高吸油性树脂是目前使用较广泛的一种解决工业废水,特别是油污染废水的方法。但目前的高吸油性树脂存在吸油速度慢、耐热性、耐寒性差,易老化、一次性使用等缺点,对吸油种类有很大的局限性、回收困难,造成了对环境的污染,治理效果不太满意,实际使用成本较高。本项目所研究的高吸油树脂吸油速度快、吸油率高,可吸油品种多、范围广,能够反复使用,减少了使用成本,避免了二次污染。其合成及处理工艺目前还没有文献报道。采用该研制的高吸油性树脂处理 相似文献

In this experimental investigation, the authors have fabricated and characterized composites made from pyrolysis oil rubber and epoxy resin. As the dumping of waste scrap tires poses a serious environmental threat, the pyrolysis oil rubber was extracted from these waste tires only. The prepared blend having pyrolysis oil with various weight percentages (wt%) was examined on the basis of various physical, microstructural, mechanical, and thermal tests. The microstructural tests (scanning electron microscopy and X‐ray diffraction) analysis complemented with the mechanical tests (tensile, compression, flexural, hardness, and impact) results and confirmed that the 4.4 wt% of pyrolysis oil in epoxy resin sample exhibited the best results in toughening of the polymer network. Furthermore, the thermal analysis (differential thermal analysis and thermogravimetric analysis), electrical conductivity, density, water absorption, gas chromatography–mass spectroscopy, and Fourier‐transform infrared tests for the composites were also performed. Low density and high tensile strength than neat epoxy resin makes this composite a potential candidate for fabricating lightweight structures and in polymer coatings for automotive industries. POLYM.

A novel high oil‐absorbing resin, P(EPDM/α‐MSt/ITA), was synthesized by suspension copolymerization with ethylene‐propylene‐diene (EPDM), α‐methylstyrene (α‐MSt), and itaconic acid (ITA) as monomers, benzoyl peroxide as initiator, and divinylbenzene as crosslink agent in this study. By using methods such as infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy, we studied the oil‐absorbing resin structure, oil‐absorption rate, oil‐absorption saturation time, and submicroscopic structure of oil‐absorption resin after oil absorption. The experiment results show that the highest oil absorptivity of the resin was about 21.9 g/g in diesel oil, obviously increasing the oil absorptive properties by the addition of itaconic acid as reaction monomer. We can draw a conclusion from scanning electron microscopy observation of sample after oil absorption that the oil‐absorption resin was filled with diesel oil, and a kind of morphology structure similar with embossment can be produced during the oil‐absorbing process. The oil‐absorbing resin was used repeatedly through the extraction by ethanol. Experiment result proved to have little effect on oil‐absorption properties. Otherwise, the oil‐absorption rate constant K of novel high oil‐absorbing resin was evaluated for diesel oil, and the oil‐absorbing process obeyed the first‐order kinetics equation. POLYM. ENG.
