丙烯酸酯共聚高吸油树脂的合成及性能

Preparation and Properties of Acrylate High Oil Absorption Resin

摘要:

采用悬浮聚合的方法，以丙烯酸丁酯(BA)和甲基丙烯酸甲酯(MMA)为单体、过氧化二苯甲酰(BPO)为引发剂、邻苯二甲酸二烯丙酯(DAP)为交联剂、聚乙烯吡咯烷酮(PVP)为分散剂，合成了丙烯酸酯类高吸油性树脂(AOA树脂)。采用红外光谱分析法(FTIR)对AOA树脂进行了表征，并在不同油品中研究了树脂的饱和吸油率、离心保油率。结果表明，两种单体悬浮共聚合成了AOA树脂，其对各种油品均有较强的的吸收，但对于不同种类油品的吸收能力并不相同，其饱和吸油率依次为：卤代烃>芳香烃>丙酮>脂肪族及环烷烃，并通过热重分析(TG)和重复吸油实验证明了合成的AOA树脂在较高的环境温度条件下能够稳定使用，并保持较高的饱和吸油率重复多次进行吸油，环保高效。

Abstract:

An acrylate high oil-absorbing resin was prepared by suspension polymerization of using butyl acrylate (BA) and methyl methacrylate (MMA) as monomers, dibenzoyl peroxide (BPO) as a evocating agent, diallyl phthalate (DAP) as a crosslinking agent, and polyvinyl pyrrolidone (PVP) as a dispersing agent .AOA resin was characterized by FTIR, and the saturated Oil absorption rate, and centrifugal oil retention rate of the resin were studied in different kinds of oil. The results show that AOA resin which is composed of two monomers by suspension polymerization can absorb all kinds of oil strongly, but the oil absorption capacity of different kinds of oil is not the same. The order of saturated oil absorption rate is halogenated hydrocarbon > aromatic hydrocarbon > acetone > aliphatic group and cycloalkane. It is proved that the synthesized AOA resin can be used stably at high temperature and keep a high saturated oil absorption rate repeatedly by thermogravimetric analysis（TG）and repetitive experiment environment-friendly and efficiently.
