Description

一种气孔稳定的发泡水泥聚氨酯泡沫复合保温板
技术领域
本发明涉及建材技术领域，尤其涉及一种气孔稳定的发泡水泥聚氨酯泡沫复合保温板。
背景技术
建筑节能政策和建筑防火规范的实施，推动了墙体保温材料的快速发展。聚氨酯硬质泡沫塑料板、聚苯乙烯泡沫塑料板、 酚醛泡沫塑料板等有机保温材料，因其保温隔热性能优异在建筑保温工程中得到了较为广泛的应用。聚氨酯泡沫致命的弱点就是燃烧性能，易被点燃，且燃烧过程释放有害气体。即使添加了阻燃剂也无法从根本上改变这一属性，建筑用聚氨酯泡沫板的最高燃烧级别也只能做到 B1 级。发泡水泥保温板、膨胀珍珠岩保温板、无机材料包裹聚苯颗粒保温板等无机保温材料， 可以达到燃烧性能分级的A级不燃材料标准要求，在建筑领域也得到了较为普遍的应用，但是由于其保温隔热性能低于有机保温材料，导热系数是有机保温材料的1.5-2倍，密度大，自重大，随着我国建筑节能要求的逐步提高，往往不能满足现行建筑节能设计标准要求。研发适应于现行建筑节能设计标准要求和防火规范的建筑保温材料已成为当前的研究热点。
《发泡水泥/注塑复合保温板的制备与性能研究》一文中，以发泡水泥保温板作为一侧模板，在模具中注塑发泡聚氨酯材料有机保温材料，经加温、加压成型，脱模后形成发泡水泥/注塑复合保温板，发泡水泥保温板位于发泡水泥/注塑复合保温板的外部，燃烧性能达A1级，当遇火遇热时， 热量主要集中在此，不会有太多的热量进入到聚氨酯保温层，能够起到防火的作用。制成的复合保温板具有良好的防火性能，而且厚度小，复合板整体密度低，降低了生产过程中的能耗，环保节能；但是由于发泡水泥层位于保温板的外部，质轻多孔的特点使其具有较高的吸水性，含水率越高，保温性越差，强度也越低，这就限制了复合保温板的应用，需要对此进行改性。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种气孔稳定的发泡水泥聚氨酯泡沫复合保温板。
本发明是通过以下技术方案实现的：
一种气孔稳定的发泡水泥聚氨酯泡沫复合保温板，由下列重量份的原料制备制成：废旧棉麻纤维3-4、氯化石蜡1-1.2、脂肪醇聚氧乙烯醚0.3-0.34、超高细硅酸盐水泥45-50、浓度为30wt%双氧水3.5-4、石膏粉3-3.5、硬脂酸2-3、硫酸铝2.5-3、有机硅乳1.6-1.8、聚丙烯酸0.9-1.2、羧甲基纤维素3-4、轻质碳酸钙2-3、明胶1.3-1.5去离子水适量、聚氧化丙烯多元醇75-80、异氰酸酯23-25、五甲基二乙基三胺2.2-2.4、正戊烷10-12、二甲基硅油1.5-2、高聚磷酸铵8-10。
所述一种气孔稳定的发泡水泥聚氨酯泡沫复合保温板，由以下具体步骤制成：
（1）去除废弃棉麻纤维中杂质，并剪成10毫米左右的短纤维待用；将氯化石蜡在90-100℃的油浴中加热1-1.5小时，然后加入脂肪醇聚氧乙烯醚，搅拌30-40分钟后，加入总量3-4倍量的去离子水，然后冷却至室温后与上述短纤维混合，搅拌分散均匀后离心分离，干燥，得到防水改性增强纤维；
（2）将轻质碳酸钙放入粉碎机中粉碎，过120目筛待用；将羧甲基纤维素、明胶混合，加入总量3-4倍量的去离子水中，边搅拌边加热至完全溶解，然后与上述轻质碳酸钙粉体、聚丙烯酸混合，以600-800转/分的速度搅拌30-40分钟，最后喷雾干燥，得到改性粉末；
（3）将有机硅乳液与25-28倍量的去离子水混合均匀，然后加入超高细硅酸盐水泥、石膏粉、步骤（1）得到的防水改性增强纤维，搅拌60-90秒后加入硬脂酸、硫酸铝、步骤（2）得到的改性粉末，继续搅拌60-90秒后加入浓度为30wt%双氧水，快速搅拌10秒后后浇入模具，待发气完成后带模具养护24小时，然后拆模、切割，并用薄膜包裹养护28天得到发泡水泥；
（4）将聚氧化丙烯多元醇与正戊烷混合，然后加入五甲基二乙基三胺以及与其等量的去离子水、高聚磷酸铵，室温下以800-1000转/分的速度搅拌100-120秒，最后加入其余剩余成分，搅拌10-15秒后注入以步骤（3）得到的发泡水泥为一侧模板的模具中，在压力为13-16MPa，温度为40-50℃下成型，最后在90-100℃下熟化15-20分钟，脱模，即得。
本发明的优点是：本发明将采用发泡水泥作为一侧模板，将聚氨酯泡沫注塑在其表面，在注塑成型的过程中，聚氨酯成分渗透到发泡水泥保温板内部并固化定型，形成良好的结合界面，提高了界面结合强度，且不需要额外添加胶黏剂，节能环保，同时由于发泡水泥层位于复合保温板的外侧，当遇火遇热时，热量主要集中在此，不会有太多的热量进入到聚氨酯保温层，能够起到防火的作用。同时发泡水泥材料层作为聚氨酯泡沫保温层与外界的过渡层，起到中间过渡作用，降低聚氨酯保温板的内外温度差及尺寸稳定性问题，进而提高系统的整体质量。本发明在发泡水泥的制备中添加废弃棉麻纤维，通过氯化石蜡的处理，提高了防水性能，进一步提高了阻燃性能，降低了发泡水泥层的吸水率，提高了复合保温板的保温效果，同时节能环保，降低了生产成本。
本发明在发泡水泥的制备中添加明胶、羧甲基纤维素、轻质碳酸钙等成分制成的改性粉体，配合双氧水的添加，可以行成气泡壁加厚，气孔稳定，孔径小，分布匀称的发泡水泥层，降低了发泡水泥层的导热系数；本发明复合保温板导热系数低，保温性能佳，防火优异，使用寿命长。
