背景技术
建筑内墙涂料，由于其施工简易、美观大方，在家居、办公等装饰中起着重要的作用，但是一些不合格的产品，出现了很多危害人体健康的问题，例如：不合格涂料释放甲醛、挥发性有机物VOC等，从而刺激人的皮肤、呼吸道、致突变性，甚至发生癌变等。如何获得安全、绿色、环保、持久、耐候的建筑内墙涂料，已经成为建筑领域的研究热点。
离子液体是一种液态的，由阴、阳离子组成的盐，部分离子液体具有表面活性剂功能，CN 103168026A报道了包含多官能阳离子的可聚合离子液体及抗静电涂料。化学制备技术，具有成本低廉、产品结构、功能可以调控等特点，在制备多组分、多功能复合材料领域，具有独特优势。
因此，寻找一种绿色环保的建筑内墙复合涂料，已成为环保建材领域的一种迫切需求。

本发明的技术方案：首先，在一定量水溶液中，加入离子液体、聚乙烯醇、聚乙二醇及硅藻土，水浴控温、搅拌一段时间，加入异丙醇铝，搅拌反应一段时间，得到复合物A；其次，向复合物A中，滴加钛酸丁酯，搅拌均匀，转移至反应釜中进行水热反应，控制反应温度和时间，制得复合物B；最后，向水性乳液中添加复合物B，搅拌均匀，制得建筑内墙复合涂料C。
其中，离子液体作为新型的表面活性剂，聚乙烯醇作为粘结剂，聚乙二醇作为分散剂，硅藻土作为无机吸附材料，异丙醇铝在水解过程中，与离子液体、聚乙烯醇、聚乙二醇及硅藻土相互作用，形成复合离子液体、聚乙烯醇、聚乙二醇、硅藻土、纳米勃姆石的复合物A；复合物A与钛酸丁酯偶联作用，在水热条件下反应，形成含有离子液体、聚乙烯醇、聚乙二醇、硅藻土、纳米勃姆石、纳米二氧化钛的复合物B；含有多官能团的复合物B与水性乳液搅拌均匀，形成建筑内墙复合涂料C。
本发明与现有技术相比，具有显著优点：其一、该建筑内墙复合涂料复合了离子液体、聚乙烯醇、聚乙二醇、硅藻土、纳米勃姆石、纳米二氧化钛及水性乳液，能有效吸附并去除空气中有毒有害气体，如甲醛、甲苯、臭味等；其二、该建筑内墙复合涂料耐候性好、不易开裂、绿色环保。
