Description

一种吸附树脂
技术领域:
本发明涉及树脂技术领域,具体是一种吸附树脂。
背景技术:
吸附树脂是以吸附为特点,具有多孔立体结构的树脂吸附剂。它是最近几年高分子领域里新发展起来的一种多孔性树脂,由苯乙烯和二乙烯苯等单体,在甲苯等有机溶剂存在下,通过悬浮共聚法制得的鱼籽样的小圆球。吸附树脂常常用于污水处理以及提取等领域。现有的用于氨基酸提取用的树脂一般为比较普通的吸附树脂,吸附能力弱,吸附量小,提取效果差,孔径分布不均匀合理,机械强度低,洗脱再生能力弱。
发明内容:
本发明所要解决的技术问题在于提供一种对氨基酸吸附量大,机械强度好,使用寿命长,孔径分布均匀合理,洗脱再生能力强的氨基酸提取专用树脂。
本发明所要解决的技术问题采用以下技术方案来实现。
一种吸附树脂,其特征在于:按重量份包括以下组分,
优选的技术方案为。
所述的致孔剂为甲苯和正庚烷混合物,甲苯和正庚烷的混合比例为1:2.2~3.5。
沸石可以借水的渗滤作用,以进行阳离子的交换,,其成分中的钠、钙离子可与水溶液中的钾、镁等离子交换,不同的离子交换对沸石结构影响很小,但使沸石的性质发生变化。晶格中存在的大小不同空腔,可以吸取或过滤大小不同的其他物质的分子。工业上常将其作为分子筛,以净化或分离混合成分的物质。沸石除本身具有吸附性外,沸石晶体分布均匀能改改善吸附树脂孔径分布,使得孔径分布均匀,从而具有更好的吸附能力。
本发明中成强酸性,强酸性不仅能扩大吸附树脂的孔径,使其更容易吸附粒径相对比较大的氨基酸颗粒,而且酸性也可以改善沸石的作为分子筛的孔径,改善沸石的能力。
本申请中将活性二氧化硅颗粒充分、均匀地分散到树脂材料中,可全面改善树脂基材料性能。不仅包括:提高强度和延伸率;提高耐磨性和改善材料表面的光洁度等,而且在提高延伸率的同时同样增加了其吸附能力,也使得吸附树脂更容易洗脱。活性二氧化硅与沸石能够与氢氧化物碱性物质发生反应生产胶凝物质能够与明胶一起起到凝固成型的作用。
本发明的有益效果是:本发明对氨基酸吸附量大,机械强度好,使用寿命长,孔径分布均匀合理,洗脱再生能力强。
具体实施方式:
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施例,进一步阐述本发明。
实施例一
一种吸附树脂,按重量份包括以下组分,
致孔剂为甲苯和正庚烷混合物,甲苯和正庚烷的混合比例为1:2.2。
