Description

一种用于铝合金的粉末多孔防火绝热涂层及其制备方法
技术领域
本发明属于防火绝热涂料技术领域,涉及一种用于铝合金的粉末多孔防火绝热涂层,本发明还涉及该种用于铝合金的粉末多孔防火绝热涂层的制备方法。
背景技术
防火涂料由基料及阻燃添加剂两部分组成,除了应具有普通涂料的装饰作用和对基材提供物理保护外,还需要具有阻燃耐火的特殊功能。因此防火涂料是一种集装饰和防火为一体的特种涂料,同时还具有防腐、防锈、耐酸碱、耐候、耐水、耐盐雾等功能,一旦发生火灾,防火涂料具有显著的防火隔热效果,能有效地阻止火焰的传播,阻止火势的蔓延扩大,广泛应用于建筑基材、城市交通等各个领域。
而铝合金以其轻量化的性能,无论是作为一种装饰性材料,还是在工业上的应用,都越来越受到人们的青睐。目前,铝合金已经被广泛的应用于高层建筑和轨道交通的内饰。在铝合金表面涂装的防火涂层,是一种集装饰、保护和防火为一体的涂层,当它涂覆于铝合金基材上时,平时可起到一定的装饰、保护作用,一旦火灾发生时,则具有防止火势蔓延的作用,同时防止铝合金过早软化。
随着我国轨道交通等领域的不断发展,研究高防火性、高环保性等高性能的防火涂料已经刻不容缓。
发明内容
本发明的目的是提供一种用于铝合金的粉末多孔防火绝热涂层,解决了现有技术防火隔热效果不理想,不符合环保要求,制作成本高的问题。
本发明的另一个目的是提供该种用于铝合金的粉末多孔防火绝热涂层的制备方法。
本发明所采用的技术方案是,一种用于铝合金的粉末多孔防火绝热涂层,按照质量百分比,由以下组分组成:铝矾土粉末70%~90%、EPS粉末0.1%~1%、聚四氟乙烯5%~15%、磷酸铜5%~15%,合计为100%。
本发明所采用的另一个技术方案是,一种用于铝合金的粉末多孔防火绝热涂层的制备方法,按照以下步骤实施:
步骤1、按照质量百分比称量各个组分,
铝矾土粉末70%~90%、EPS粉末0.1%~1%、聚四氟乙烯5%~15%、磷酸铜5%~15%,合计为100%;
步骤2、将步骤1称量好的铝矾土粉末、EPS粉末、聚四氟乙烯、磷酸铜进行充分混合,得到混合物A;
步骤3、将步骤2得到的混合物A置于行星式球磨机上进行高速分散混合,充分搅拌5~10小时,得到粉末形状的防火绝热涂料B;
步骤4、利用喷枪将步骤3所得粉末防火绝热涂料B喷涂于经过预处理后的铝合金表面,喷涂2~3次,并于150℃~350℃温度下进行30~90min烘干处理,得到粉末多孔防火绝热涂层,最后涂刷防火涂料配套面漆。
本发明的有益效果是,
1)本发明用于铝合金的粉末多孔防火绝热涂层具有优良的耐热性,能阻止火焰蔓延,掺入大量的轻质填料,因而涂层的导热系数小,具有良好的隔热作用,起到防火和保护基材的作用。
2)本发明成分简单,所选用的耐火材料铝矾土粉末资源丰富,耐火度高,质量轻,化学稳定性强,物理性能良好。EPS粉末量轻、易获得,烘干时软化,最后气化,达到造孔的目的。粘结剂选用聚四氟乙烯和磷酸铜两种材料,其中磷酸铜在高温下发挥作用,提高涂料的粘度及均匀性。
3)本发明原料来源广泛,成本低廉,制备工艺方法简单、操作方便,无需特殊的设备,适合大规模生产。
4)本发明所得涂层在1000℃下30min内不燃、无烟、不开裂脱落、不产生刺激性气味,具有优异的阻燃耐火性能,此外,还具有优异的机械性能、耐老化性能、耐腐蚀性能和耐磨性能。
5)面漆的配套使用使防火涂层耐火性能增强,且保护涂层免受湿气、灰尘等负面影响。
6)用于铝合金表面,该粉末多孔防火绝热涂层具有优良的防火性、良好的耐热性、质量轻,遇火时不冒烟、无刺激性气味、不开裂脱落,具有良好的物理化学性能、环保性能等,社会经济效益明显。
