Description
技术领域
本发明涉及消防材料领域,具体涉及一种无机外墙用防火保温板。
背景技术
随着节约能源与环保要求的不断提高,产业用建筑围护结构用材料的保温技术也在日益加强,尤其是外墙保温技术,在建筑节能技术中具有越来越重要的地位。外墙保温是将保温材料设置在外墙一侧的保温形式,通常采用外墙外保温系统来实现。外墙外保温系统是多层外墙复合体系,它能够将水和湿气阻挡在复合墙体外表面之外,不容许水通过垂直墙体表面或任何洞口和接缝处渗入系统,从而保证系统的长期可靠性,它是集节能、保温、隔音、装饰效果为一体的轻质、环保型非承重性外围护建筑墙体。
公安部消防局公布数据显示,每年因火灾造成的直接财产损失在50亿元左右,伤亡人数3000人以上,其中以居民住宅火灾伤亡人数比例最高。而不合格的外墙用防火保温材料是导致火灾事故的一大原因。
现有在墙体防火保温领域,应用较广的保温材料包括热塑性有机泡沫板和无机水泥发泡保温板,热塑性有机泡沫板的使用为建筑外墙的节能提供了有效的保温,但由于热塑性有机泡沫板自身防火性能差,即使在其表层添加阻燃剂表面涂层,仍不能达到A级防火性能的要求,且其寿命小。无机水泥发泡保温板主要材料是水泥,加入发泡剂融合发泡而成,其具有导热系数低,保温效果好,强度高,防火防水,寿命长等优点,被广泛应用于有较高等级防火要求的建筑物外保温层。而现有的无机外墙用防火保温板大多只能瞬间耐高温,且瞬时耐高温一般都在600-700 度,防火阻燃能力有限。
发明内容
本发明目的是提供一种无机外墙用防火保温板,防火阻燃能力好、保温性能好、强度高。
为了实现以上目的,本发明采用的技术方案为:一种无机外墙用防火保温板,按照重量百分比的原料包括:水泥15~21%;水泥发泡剂2~5%;铁矿尾矿粉16~22%;聚炳烯纤维5~11%;亚纳米SiO21~3%;粉煤灰10~16%;硬脂酸钙1~5%;三乙醇胺0.2~0.8%;过氧化氢3~9%;纤维素纤维1~3%;水22~28%。
优选的,按照重量百分比的原料包括:水泥18%;水泥发泡剂3.5%;铁矿尾矿粉19%;聚炳烯纤维8%;亚纳米SiO22%;粉煤灰13%;硬脂酸钙3%;三乙醇胺0.5%;过氧化氢6%;纤维素纤维2%;水25%。
进一步的,所述的所述水泥为PSA32.5 水泥。
进一步的,所述的水为48~52°C的温水。
本发明的技术效果在于:本发明无机外墙用防火保温板中由于采用铁矿尾矿粉、聚炳烯纤维、亚纳米、粉煤灰、硬脂酸钙、三乙醇胺、纤维素纤维。使得本无机外墙用防火保温板的产品强度可以达到3 kg/cm²,安全可靠,从而使得产品在使用及运输中的过程中不易破损,节约了使用者的成本;且本发明无机外墙用防火保温板保持了良好的保温性能,为匀制制品,而且按GB8624-2006“建筑材料及制品燃烧性能分级”的检验,其燃烧性能达到了A1 级不燃,导热系数低;充分利用铁矿尾矿粉和粉煤灰等工业废料,产品性能稳定;得到的产品瞬时耐高温温度高达800°C,且保持无机外墙用防火保温板在500°C高温下达到2小时防火阻燃的能力。
