Description
本发明涉及一种防火漆、制备方法和应用，具体涉及一种水性超薄膨胀型防火漆及其制备方法和应用，属于涂料领域。
防火漆是由成膜剂、阻燃剂、发泡剂等多种材料制造而成的一种阻燃涂料；由于目前家居中大量使用木材、布料等易燃材料，所以，防火已经是一个值得提起的议题。现有的防火漆可以分为饰面防火漆、木材防火漆、钢结构防火漆三种。饰面型防火漆是一种集装饰和防火为一体的新型油漆品种，当它涂覆于可燃基材上时，平时可起一定的装饰作用；一旦火灾发生时，则具有阻止火势蔓延，从而达到保护可燃基材的目的。饰面防火漆中应用较多的，效果较好的为膨胀型防火漆。
在涂料工业领域，溶剂型涂料含有大量的挥发性有机溶剂(VOC)，在使用过程中排入大气，不仅破坏大气环境，危害人们健康，同时也浪费资源，浪费能源。目前，一般将水性涂料、粉末涂料、高固分涂料以及辐射固化涂料称为环保涂料。
以水溶性树脂或水分散性树脂，包括合成聚合物乳液为基料的涂料均称为水性涂料。因此水性涂料也常称为水基涂料。合成聚合物乳液为基料的涂料均称为水性涂料。
现在钢结构上一直应用传统的油漆产品，主要成分为二甲苯、丁醇、石油树脂等，属于易燃易爆品，VOC严重超标，环保形势下属于禁用产品，现在大力倡导环保安全，全部改换成环保水性漆产品是必然趋势。水性漆在钢结构上的应用容易脱落，防火性能差、附着力达不到、防腐性能达不到等弊病。
有鉴于此，本发明提供了一种水性超薄膨胀型防火漆及其制备方法和应用，具体采用如下技术方案：

3）向搅拌好的液体中加入膨胀石墨和色浆，继续搅拌；
4）向搅拌好的液体中依次加入消泡剂、分散剂、增稠剂，搅拌均匀即得水性超薄膨胀型防火漆。
进一步，步骤2）中所述搅拌的转速为1000-1200转/分钟，搅拌时间为20-30分钟。
进一步，步骤3）中所述继续搅拌的转速为200-300转/分钟，搅拌时间为5-10分钟。
进一步，步骤4）还包括在加入消泡剂、分散剂、增稠剂的同时搅拌的操作。
本发明还限定了上述水性超薄膨胀型防火漆在钢结构上的应用。
本发明的有益效果在于，本发明以水作溶剂，节省大量资源，不含苯、二甲苯、乙烷、甲醛等VOC有害物质，防腐性能优良，复涂性能良好，抗辐射，不经过任何研磨程序，直接搅拌即可，制备方法简单可靠，消除了施工、储存时火灾隐患，降低了对大气污染，在密闭环境中也可照常施工。本发明在钢结构表面附着力强，具有优异的防火性能，同时又有防腐防锈性能，耐水、耐酸耐碱、耐候性强，环境友好型，操作性能简单，涂装工具可用水直接清洗，大大有效减少对施工人员的伤害，可以在钢结构上运用广泛，可在室外大面积施工，方法简单易施工（喷涂、刷涂、滚涂、静电喷涂等）。
