Description
技术领域
本申请涉及一种防火门,适用于防火安全的技术领域。
背景技术
目前的防火门主要是采用无机矿物作为主要原料制备的门芯板。缺点在于无机矿物原料的开采和生产过程属于高能耗、高污染行业。无机矿物属于不可再生资源,开发对自然环境造成了极大的破坏,并产生大量粉尘,这限制了其可持续开发应用。以无机矿物为原料制备的防火门笨重,安装费时、费力。所以,在不降低防火门性能的前提条件下,如何降低防火门的重量,并使用绿色可再生材料代替无机矿物类材料是防火门未来的发展方向。
绿色可再生材料是指采用清洁生产技术、少用天然资源和能源、大量使用工业或城市固态废物生产的无毒害、无污染、无放射性、有利于环境保护和人体健康的建筑材料。它具有消磁、消声、调光、调温、隔热、防火、抗静电的性能。这些绿色材料主要包括可再生、可回收、可再循环的生物质材料,例如树木和采伐加工剩余物,秸秆和农业剩余物,城市垃圾中的纸质,木质,塑料泡沫和其他纤维结构材料等等。

因此,现有技术中急需一种轻质、环保、耐火性能好的防火门。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不用于限定本发明。
如图1所示,其中显示了根据本申请的防火门的一种典型结构,包括面板1和芯板3,面板1和芯板3之间设置粘结层2。其中,芯板3的两侧均设置有面板,并且两侧的面板和芯板之间均设有粘结层,芯板3可以为蜂窝结构,以减轻自重。如图2所示,其中的防火门的芯板3包括两层,两层芯板3之间也通过粘结层2进行粘结,芯板3为蜂窝结构。如图3所示,芯板还可以为实心门芯4,并且还可以仅在芯板的一侧设置面板。本领域技术人员知道,还可以对本申请的防火门进行各种可能的变形,例如芯板可以设置为三层以上,图3中芯板的另一侧涂覆防火涂料等。在上述结构中,面板起隔热和提高强度的作用,封面材料可以是纸板、木板、塑料板、金属板、无机复合板;面板材料可以是纸板、木板、塑料板,可进行阻燃处理。金属板可以是铝、铁、铜或合金材料。无机复合板可以是珍珠岩、蛭石、硅酸盐、氧化镁、氧化铝、氯化镁、硫酸铝以及岩棉材质;也可以是保全板、纤维增强硅酸盐板、玻镁板等。面板的厚度为0.1-5厘米,可以根据实际情况选择合适厚度。
在优选实施方式中,芯板3可以采用聚苯乙烯颗粒填充,以减轻重量;门芯可采用多层结构,层与层之间可采用无机或有机胶粘结,优选无机粘结剂;门芯的层与层之间也可采用平面、波浪、锯齿的形状固定;或者,既采用形状固定,同时又采用粘结胶固定。作为本发明的技术方案,芯板可采用实心或蜂窝结构。蜂窝结构作为一种优选的技术方案,蜂窝结构中的孔可以是规则和/或不规则的圆形、多边形、或其他不规则形状等,孔径从0.1厘米到5厘米。作为本发明的一种优选技术方案,芯板的两侧加装面板,面板通过无机粘合剂来固定到门芯材料上。无机粘结剂优选无机硅酸盐类粘结剂。无机硅酸盐类粘结剂不仅起到粘结作用以固定蜂窝结构,而且无机硅酸盐类粘结剂也是不燃物,在火灾发生过程中,无机硅酸盐类粘结剂起到隔热作用,对蜂窝结构起到第一道的防火隔热保护。同时,可在无机硅酸盐类粘结剂中添加遇热膨胀材料。膨胀材料在受火时,可迅速激发膨胀,填充蜂窝中的中空部位。遇热膨胀材料材质轻,膨胀可达200-400倍,具有很好的隔热效果。优选的遇热膨胀材料,例如可以是珍珠岩、膨胀石墨、膨胀蛭石等。
本申请中为了减轻防火门的自重,可以在芯板中添加聚苯乙烯颗粒或者做成蜂窝结构或两者兼施。聚苯乙烯具有密度低和重量轻的特点,将其混入门芯中,可以极大降低门芯的重量。另外,蜂窝结构具有节约资源,保护生态环境,降低成本的作用。将蜂窝状芯材两面牢固地粘结两块较薄的面板而制成的板材,亦称蜂窝夹层结构,具有轻、强、稳、保温、隔热、防震等诸多优点。门芯的隔热效果可以通过聚苯乙烯颗粒和空气的低导热系数实现。聚苯乙烯的导热系数一般在0.032-0.038W/(m·K)范围内;在不考虑热辐射的条件下,空气的导热系数低于0.03W/(m·K),都属于低导热材料。
作为本发明的一种优选技术方案,用于蜂窝防火门芯的材料优选为绿色可再生材料。由于绿色可再生材料一般是易燃材料,利用无机阻燃剂和无机粘合剂的复配使用,达到对绿色可再生材料的阻燃处理。阻燃处理是通过无机阻燃剂和无机粘合剂对绿色可再生材料的包裹覆盖实现。下面通过实施例来说明利用绿色可再生材料、无机阻燃成分和无机粘合剂来制作复合芯板的过程。
所述芯板由以下重量份数的原料制成:
绿色可再生材料100份;
聚苯乙烯颗粒10-30份;
氧化镁50份;
氯化镁50份;
增强剂1-2.5份;
发泡剂0.8-1份;
抗水剂1份;
稳定剂0.1份;
可再分散胶粉2.5-4份;
聚丙烯短纤维0.1-0.3份;
憎水剂1-2份;
水10-30份。
其制备过程如下:
(1)将绿色可再生材料、氧化镁、氯化镁、聚丙烯短纤维、增强剂搅拌均匀,然后加入抗水剂、稳定剂、憎水剂、可再分散胶粉并继续搅拌均匀,形成浆料;
(2)在另一个装有聚苯颗粒的搅拌机内,导入均匀的浆料搅拌5~8分钟,直至浆料和聚苯颗粒均匀分散;
(3)将发泡剂加入搅拌好的浆料中,继续搅拌均匀后,倒入模具或平模板上固化成型;
(4)在15~35℃的温度,湿度小于70%的环境下,养护10~16小时即可脱模。
(5)继续养护10~15小时,按尺寸切割,磨光磨平。
本申请中的粘结层可以采用有机粘合剂和无机粘合剂。考虑到火灾发生时需要减少有毒气体和烟的释放,粘合剂优选采用无机粘合剂,特别优选硅酸盐类粘合剂。本发明提出一种耐水性硅酸盐类粘合剂。该无机粘合剂与传统的有机粘合剂相比,这种水玻璃粘合剂成本低、无污染、耐水、防火阻燃,也可以直接用作耐水防火阻燃漆。
根据本申请的无机粘合剂,包括以下质量份数的组分:
碱金属硅酸盐50-200份;
硅溶胶1-10份;
水溶性磷酸硅5-10份;
磷酸硅或聚磷酸硅10-40份;
无机酸(例如磷酸,硫酸,盐酸,硼酸等)0.1-5份。
其制备方法如下:
(1)将规定量的碱金属硅酸盐溶液倒入容器中,在不停地搅拌下缓慢滴加计量的无机酸使其充分混合;
(2)再往容器中加入规定量的硅溶胶,高速搅拌;
(3)再往容器中加入规定量的水溶性磷酸硅(可以先溶解于少量水中),高速搅拌;
(4)再往容器中加入规定量的磷酸硅或聚磷酸硅(可以先分散于少量水中),高速搅拌;
(5)最后加入润湿剂和其他辅料,持续搅拌均匀,即可得一种高附着力,高耐水性的水玻璃改性涂料。
优选地,根据本申请的无机粘合剂,包括以下质量份数的组分:
硅酸钾30-90份;
硅酸钠30-90份;
硅酸锂1-5份;
硅溶胶1-10份;
聚磷酸硅5-20份;
磷酸硅5-20份;
水溶性磷酸硅5-10份;
水10-30份;
无机酸(例如磷酸,硫酸,盐酸,硼酸等)0.1-5份;
润湿剂0.1-5份;
辅料(例如氟硅化物、缩合磷酸铝、氧化钙、氧化铝、二氧化硅、氧化锌、醋酸酯或磷酸盐类硬化剂等)1-2份。
在本发明中,无机酸可以起到对水玻璃改性的作用,硅溶胶可以提高成膜的强度;采用的固化剂为多聚磷酸硅,磷酸硅及水溶性磷酸硅。为进一步提高耐水时间,可以添加一些氟硅化物、缩合磷酸铝、氧化钙、氧化铝、二氧化硅、氧化锌、醋酸酯和磷酸盐类硬化剂之类的辅料。作为一种优选的技术方案,所述的水玻璃是硅酸钠和硅酸钾,为提高其耐水性可适当添加硅酸锂;硅酸锂有自干性,溶液水分蒸发后能生成一种不溶于水的膜,具有水不可逆性,有利于提高整个水玻璃成膜物质的稳定性和耐水性。
作为一种优选的技术方案,所述耐水性提高以后的水玻璃组合可以添加适当润湿剂和增稠剂,以调节涂料的表面张力和成膜性,有利于涂料的施工。可以轻易的涂刷或喷涂在有有机底漆,或表面能低的材质表面。该水玻璃成膜物质组合可以单独作为无机防火漆,也可以作为无机防腐涂料,室内外无机涂料的底料,在添加各种功能粉料以后,制备成各种无机功能涂料。
