Description

一种墙体保温材料
技术领域
本发明涉及建筑材料领域，特别涉及一种墙体保温材料。
背景技术
我国每年城乡新建房屋建筑面积近20亿平方米，既有建筑近420亿平方米，建筑能耗已占全国总能耗的27％以上，建筑节能问题已成为我国可持续发展的重要环节，尤其是围护结构的节能具有特别重要的地位。近几年聚苯泡沫板保温便应运而生，聚苯板保温效果非常好，而且密度非常低，能达到100kg/m3以下，但其致命缺陷是易燃，而且燃烧后发烟量大，所以其使用受到极大限制。近年来，北京、上海、沈阳等地发生了因保温层燃烧而引起的“央视大楼”、“上海教师公寓”、“沈阳万鑫酒店”火灾，充分暴露出传统有机保温材料的防火缺陷。住建部也在大力提倡开发新型的阻燃、轻质的保温材料。
玻化微珠保温砂浆是一种以玻化微珠为骨料的无机保温材料，因玻化微珠内部为蜂窝状空腔结构，表面形成玻璃体薄壳，因而具有质轻、吸水率低、强度高、理化性能稳定的特点。然而，目前我们国内生产的大部分玻化微珠都存在容重和吸水率过大问题。我国南方地区利用玻化微珠作骨料配制的保温砂浆干密度普遍偏高，使其保温性能大受影响。同时，目前制备的玻化微珠保温材料，因玻化微珠的吸水率(60％～150％)过大，导致其吸水率高，且制备的保温材料容重大多为300～500kg/m3，导热系数为0.075～1.5/W/m·K，而且强度偏低，不能够满足我国建筑节能65％的要求，特别是在寒冷的北方。
发明内容
本发明要解决的技术问题是提供一种阻燃性和抑烟性良好，且吸水率低以及抗压强度高的墙体保温材料。
为解决上述技术问题，本发明的技术方案为：一种墙体保温材料，其创新点在于：按重量分数配比由以下组分制成：
聚氯乙烯树脂粉76-103份、开孔膨胀珍珠岩 12-16 份、包膜玻化微珠43-46份、PE12-32 份、稳定剂5-8份、PLA 6-11份、乙烯—醋酸乙烯共聚物12-17份、纳米级颗粒无机材料8-11 份、内润滑剂2-4份、碳酸钙 25-33份、发泡剂3-12份、云母粉 12-24 份。
进一步的，所述聚氯乙烯树脂粉的聚合度为600-1100。
进一步的，所述稳定剂为复合铅类稳定剂、钙锌类稳定剂或有机锡稳定剂。
进一步的，所述内润滑剂为硬脂酸、硬脂酸酯、硬脂酸醇化合物、硬脂酸酰胺类、脂肪酸金属皂类、聚乙烯蜡、石蜡或氧化聚乙烯。
进一步的，所述发泡剂为碳酸氢钠、碳酸氢铵、碳酸铵或叠氮化合物。
本发明的优点在于：玻化微珠通过粉煤灰以及铁黑粉进行包膜处理，不仅能够降低玻化微珠的吸水率，而且还能够增强玻化微珠作为骨料的强度。充分利用玻化微珠理化性能十分稳定、耐老化耐候性强等优点，因此，制备出的墙体保温材料其保温性能更持久，吸水率低以及抗压强度高。
本发明制得的聚氯乙烯墙体保温材料具有良好的阻燃性和抑烟性，同时保温效果良好，生产成本低，制作工艺简单。
本发明利用各种无机填料，制备的墙体材料保温效果好，环保、制备简单方便。
