Description
技术领域
本发明涉及除甲醛技术领域，具体而言，涉及一种水基量子点除醛功能添加剂及其制备方法。
背景技术
甲醛是一种高挥发性的有机污染物。尤其是在室内装修中材料会释放多种气态污染物污染室内环境，其中的甲醛就是最典型、危害最大的污染物之一。甲醛在室内的含量越来越高，远大于室外空气中甲醛的浓度。长期接触甲醛容易引起慢性呼吸道疾病、鼻咽癌、结肠癌、脑癌、白血病等疾病。根据流行病学调查表明，非工业环境的人群(如室内居民)长期暴露在低浓度甲醛环境下，会发生眼部刺激、上呼吸道刺激、头痛和咳嗽等症状。如果长期吸入高浓度甲醛气体，还可能引发支气管哮喘，甚至会导致人体肿瘤与癌症。
目前用的除甲醛的方法主要有以下几种：(一)生物酶法。通过微生物的繁衍生产生物酶，在微生物和生物酶的双重作用下，可以将甲醛分解为二氧化碳和水，该方法有效时间较短，持续性较弱。(二)光触媒法。通过可见光活化的光触媒能够在有光线的地方持续不断地分解甲醛。氧化钛具有高的催化活性、良好的稳定性、能够降解有机污染物以及廉价无毒等优点，因此广泛应用于涂料添加剂用于去除其中的甲醛。然而，在涂料添加除醛应用中，基于氧化钛的光降解材料只能在紫外线下有较高的效率，在可见光下效率低下，严重限制氧化钛的应用。
发明内容
发明人考虑到室内环境同时存在的除甲醛和杀菌的实际需要，本发明意在合成一种新型的具有与甲醛快速反应的甲醛清除剂，不受紫外线照射应用条件限制，在可见光环境下也具有良好反应活性的除醛添加剂。
本发明发明人提出了利用量子点表面的活性键可与甲醛及有机溶剂反应，从而有效消除空气中的甲醛及TVOC的构思，本发明的目的在于提供一种水基量子点除醛功能添加剂的制备方法，制备得到的添加剂具有很好的水溶性，更容易添加到水性除醛喷剂、乳胶漆等中，并可在除醛喷剂或乳胶漆体系中分散的更均匀。
本发明的实施例通过以下技术方案实现：
一种水基量子点除醛功能添加剂的制备方法，包括以下步骤：
S1.向含有明胶的量子点金属盐溶液中通入氮气，搅拌、升温后，滴加盐酸多巴胺及四氢硼钠水溶液，滴加完毕后，调节溶液PH值至11-13，反应一段时间；
S2.将反应后的溶液冷却后，加入改性明胶水溶液，搅拌后，高速离心分离，去除上层溶液，沉淀物经分散后即得水基量子点除醛添加剂。
一种量子点除醛功能添加剂，由上述的水基量子点除醛功能添加剂的制备方法制得。
本发明实施例的技术方案至少具有如下优点和有益效果：
本发明水基量子点除醛功能添加剂的制备方法制备得到的添加剂具有很好的水溶性，更容易添加到水性除醛喷剂、乳胶漆等中，并可在除醛喷剂或乳胶漆体系中分散的更均匀；除此之外，本发明制备得到的除醛添加剂可减少纳米量子点金属颗粒的团聚，使得最终制得的除醛功能添加剂添加到除醛喷剂、乳胶漆等中后，除醛喷剂、乳胶漆的除醛效果更充分。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将对本发明实施例中的技术方案进行清楚、完整地描述。实施例中未注明具体条件者，按照常规条件或制造商建议的条件进行。所用试剂或仪器未注明生产厂商者，均为可以通过市售购买获得的常规产品。
下面对本发明实施例提供的一种量子点除醛功能添加剂及其制备方法进行具体说明。

S1.向含有明胶的量子点金属盐溶液中通入氮气，搅拌、升温后，滴加盐酸多巴胺及四氢硼钠水溶液，滴加完毕后，调节溶液PH值至11-13，反应一段时间；本发明提出了利用量子点表面的活性键可与甲醛及有机溶剂反应，从而有效消除空气中的甲醛及TVOC等的构思；并且本发明利用多巴胺的粘附效应，能够附着并包覆于所制得的纳米量子点金属表面，从而减少所得的纳米量子点金属颗粒的团聚，使得最终制得的除醛功能添加剂添加到除醛喷剂、乳胶漆等中后，除醛喷剂、乳胶漆的除醛效果更充分；
S2.将反应后的溶液冷却后，加入改性明胶水溶液，搅拌后，高速离心分离，去除上层溶液，沉淀物经分散后即得水基量子点除醛添加剂；这样可使得除醛功能添加剂具有疏松多孔的结构，具有很好的水溶性，从而有利于添加到除醛喷剂、乳胶漆等中后分散的更均匀，提高除醛效果。
进一步地，S2中，所述改性明胶包括明胶和载体，所述载体包括SiO2、CaCO3、TiO2、蒙脱土或滑石粉中的一种或几种，具有很强的吸附能力和孔隙率，从而在添加到除醛喷剂、乳胶漆等中后，可更稳定地吸附于除醛喷剂、乳胶漆体系中，并可高效地吸附空气中的甲醛等有害物质。

对比例1
本对比例与实施例1的区别在于：S1中不含盐酸多巴胺。
对比例2
本对比例与实施例1的区别在于：S2中明胶未改性。
实验例1
对实施例1-6制得的除醛功能添加剂，以及对比例1-2制得的除醛功能添加剂，采用同样的常规方法混合加入到水性除醛喷剂中后，将所得的水性除醛喷剂试验样品1-8，分别喷在具有同样浓度(初始浓度为0.50mg/m3)的甲醛测试空间内，分别进行性能测试：
需要说明的是，其检测标准依据：《居室空气中甲醛的卫生标准》规定：居室空气中甲醛的最高容许浓度为0.08mg/m3。
表1试验样品1-8的除醛喷剂的除醛性能测试
由表1数据可知，本发明实施例得到除醛功能添加剂加入到水性除醛喷剂中后，所得的水性除醛喷剂的除甲醛性能均优于对比例，且均优于《居室空气中甲醛的卫生标准》规定的标准。
而对比例1中不含盐酸多巴胺，从而使得纳米量子点金属颗粒不易团聚，这样在用于除醛喷剂中后难以聚集，对比例2中明胶未改性，这样在添加到除醛喷剂、乳胶漆等中后分散的不够均匀，从而使得最终的除甲醛的效果均不理想。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
