Abstract
本发明公开了一种改性碳纳米管的空气催化复合材料，其原料按重量份包括：活性竹炭50-150份、纳米二氧化钛20-80份、改性淀粉30-60份、改性碳纳米管5-15份、二氯异氰尿酸钠2-8份、环氧树脂1-5份、天然香料2-8份。本发明具有优异的空气净化效果，净化效率高。
Description
技术领域
本发明涉及空气净化材料技术领域，尤其涉及一种改性碳纳米管的空气催化复合材料。
背景技术
目前，空气净化材料的空气杂质的吸附效果和吸附效率低，材料的吸附效果差，且对于空气的净化效果差，无法满足实际的使用需求。
发明内容
为解决背景技术中存在的技术问题，本发明提出一种改性碳纳米管的空气催化复合材料，具有优异的空气净化效果和净化的效率。
本发明提出的一种改性碳纳米管的空气催化复合材料，其原料按重量份包括：活性竹炭50-150份、纳米二氧化钛20-80份、改性淀粉30-60份、改性碳纳米管5-15份、二氯异氰尿酸钠2-8份、环氧树脂1-5份、天然香料2-8份。
优选地，改性碳纳米管按如下工艺进行制备：在冰、水混合浴中，搅拌条件下将无水溶剂滴加到三氯化铝中，滴加完毕后，加热至三氯化铝完全溶解，得到浓度为20-50wt％的三氯化铝溶液，所述的无水溶剂为无水二甲基亚砜或N，N-二甲基乙酰胺；然后将聚乙烯醇和碳纳米管溶解于无水溶剂二甲基亚砜或二甲基甲酰胺中，得到聚乙烯醇/碳纳米管混合溶液，混合溶液中聚乙烯醇的浓度为25-55wt％，碳纳米管与聚乙烯醇的质量比为2∶8-3∶15；然后将聚乙烯醇/碳纳米管混合溶液加入到三氯化铝溶液中，在温度为60-120℃的条件下进行傅克烷基化反应15-35h，产物经后处理后得到聚乙烯醇接枝改性的碳纳米管。
本发明的一种改性碳纳米管的空气催化复合材料的原料包括活性竹炭、纳米二氧化钛、改性淀粉、改性碳纳米管、二氯异氰尿酸钠、环氧树脂和天然香料，其中，以活性竹炭为主料，活性竹炭对空气的杂质具有吸附作用，同时利用纳米二氧化钛和改性淀粉的多孔结构，使得杂质的吸附更加彻底；其中，碳纳米管被认为是复合材料的理想增强体，可以提高复合材料的韧性，强度以及导电性等，具有重大的研究价值。但是，由于碳纳米管的比表面积和表面能比较大，使得碳纳米管很容易团聚，影响了碳纳米管在基体中的分散。而且碳纳米管表面光滑，呈非极性，不溶于一般的有机溶剂，与所有的聚合物都不相容，使得复合材料的界面作用不强。为了提高碳纳米管在聚合物中的分散及增强碳纳米管与聚合物基体的界面结合力，必须对碳纳米管进行表面处。表面处理后的碳纳米管与二氯异氰尿酸钠、环氧树脂和天然香料的有效结合，使得本发明的改性碳纳米管的空气催化复合材料的吸附和空气净化效果更好。
