Description
技术领域
本发明涉及一种涂料，尤其涉及一种艾叶油去甲醛环保涂料。
背景技术
涂料是一种能牢固覆盖在物体表面，起保护、装饰、标志和其他特殊用途的化学混合物涂料。中国涂料界比较权威的《涂料工艺》一书是这样定义的：“涂料是一种材料，这种材料可以用不同的施工工艺涂覆在物件表面，形成粘附牢固、具有一定强度、连续的固态薄膜。这样形成的膜通称涂膜，又称漆膜或涂层。”属于有机化工高分子材料，所形成的涂膜属于高分子化合物类型。按照现代通行的化工产品的分类，涂料属于精细化工产品。现代的涂料正在逐步成为一类多功能性的工程材料，是化学工业中的一个重要行业。
纳米技术(nanotechnology)是用单个原子、分子制造物质的科学技术，研究结构尺寸在0.1至100纳米范围内材料的性质和应用。纳米科学技术是以许多现代先进科学技术为基础的科学技术，它是现代科学(混沌物理、量子力学、介观物理、分子生物学)和现代技术(计算机技术、微电子和扫描隧道显微镜技术、核分析技术)结合的产物，纳米科学技术又将引发一系列新的科学技术，例如：纳米物理学、纳米生物学、纳米化学、纳米电子学、纳米加工技术和纳米计量学等。
在纳米材料研究领域中，纳米银是近年来研究较多的金属纳米材料之一。由于自身具有小尺寸效应、量子尺寸效应，因而展现出许多特有功能。纳米银具有高效广谱、渗透性强、无耐药性、修护再生、抗菌持久、安全无毒、去甲醛等特点。
现有技术中，并未有一种涂料，能够有效去除甲醛。
发明内容
针对现有技术的不足，本发明所要解决的技术问题是提供一种艾叶油去甲醛环保涂料。
本发明提供了一种艾叶油去甲醛环保涂料，由下述组分组成：10-18wt％聚丙烯酸酯、2-4wt％聚丙烯酸、0.1-0.5wt％艾叶油、1-3wt％甲醛捕获剂、2-6wt％纳米银胶、余量为水。
所述纳米银胶，可以采用市售的纳米银胶，也可以采用下述方法制备而成：
将0.1wt％的环糊精水溶液与质量摩尔浓度为0.1mol/L的银氨溶液以1∶50的体积比进行混合，在80℃的温度条件下搅拌40min，即获得平均粒径为5-20nm的纳米银胶。
其中，银氨溶液的制备方法为：1.0mol/L的硝酸银溶液中滴加入0.1mol/L的氢氧化钠溶液，出现白色沉淀，然后滴加5wt％的氨水溶液，直至白色沉淀消失，得到质量摩尔浓度为0.1mol/L的银氨溶液。
所述环糊精水溶液中的环糊精为2-O-(羟丙基-N,N-二甲基-N-十六烷基铵)-β-环糊精和/或2-O-(羟丙基-N,N-二甲基-N-十八烷基铵)-β-环糊精。优选地，所述环糊精为30-70重量份2-O-(羟丙基-N,N-二甲基-N-十六烷基铵)-β-环糊精和30-70重量份2-O-(羟丙基-N,N-二甲基-N-十八烷基铵)-β-环糊精的混合物。
上述2-O-(羟丙基-N,N-二甲基-N-十六烷基铵)-β-环糊精和2-O-(羟丙基-N,N-二甲基-N-十八烷基铵)-β-环糊精的制备方法参见《功能性环糊精衍生物的设计合成及其分子识别》第128-132页所公开的方法(孙宏元；功能性环糊精衍生物的设计合成及其分子识别[D]；山东大学；2009年)。
优选的，所述甲醛捕获剂选自2-咪唑烷酮(CAS号：120-93-4)、1-(2-羟基乙基)-2-咪唑烷酮(CAS号：3699-54-5)中的一种或两种的混合物。
更优选的，所述甲醛捕获剂由40～60重量份的2-咪唑烷酮和40～60重量份的1-(2-羟基乙基)-2-咪唑烷酮共混组成。
所述聚丙烯酸酯，CAS号：57828-93-0。所述聚丙烯酸，CAS号：9003-01-4。
艾叶油为菊科植物艾(Artemisia argyi)的干叶或鲜叶中所含挥发油，其主要有效成分为蒲品烯醇-4(Terpinenol-4)与α-萜品烯醇(α-Terpineol)。特点及作用：理气血，温经脉，祛寒湿。醒脑提神、镇定神经、消除焦虑、舒缓精神紧张。镇痛、缓解肌肉疼痛。消炎消毒、抑菌防感、驱蚊止痒。止咳、祛痰、平喘。美容美体。
采用本领域通用方法，将上述原料搅拌混合均匀，即可制得本发明的艾叶油去甲醛环保涂料。
本发明的艾叶油去甲醛环保涂料还可以有效地清除甲醛污染物，净化生活空间。
具体实施方式
以下是本发明的具体实施例，对本发明的技术方案做进一步的描述，但是本发明的保护范围并不限于这些实施例。凡是不背离本发明构思的改变或等同替代均包括在本发明的保护范围之内。
