Description

一种聚苯颗粒无机保温板及其制备方法
技术领域
本发明属于建筑节能领域，尤其涉及一种聚苯颗粒无机保温板及其制备方法。
背景技术
目前使用的建筑外保温材料大多是使用易燃有毒的保温材料。一般有机保温材料的最多是B1、B2级无法达到防火的需求。现在国家出台的新的建筑防火规范要求即要防火也要保温。而全国部分省份的出台节能75％现有的保温材料有部分能达到节能要求但达不到防火要求，一部分能达到防火要求但达不到保温要求。还有部分建筑明确规定要达到不然性A级和产烟毒AQ1安全一级。因此，一种防火性能较好，保温材质佳，环保的保温板亟待研究。
发明内容
本发明为解决现存问题提供了一种聚苯颗粒无机保温板及其制备方法，制备的保温材料达到防火要求、不燃性A级。
本发明主要是通过以下技术方案加以实现的：
一种聚苯颗粒无机保温板，包括聚苯颗粒无机保温层和防护面层,其中:聚苯颗粒无机保温层的原料各组份按重量份计为：氧化镁80-100份，氯化镁54-66份，矿粉或镁质铝酸盐水泥10份，聚苯颗粒8-10份，疏水剂8份，改性剂1份，憎水粉2份，发泡剂0.4-0.65份，水65份；防护面层为网格布或无纺布。所述的聚苯颗粒无机保温层厚度为20-120mm。
作为上述技术方案的进一步优选，所述的聚苯颗粒无机保温层的原料各组份按重量份计为：氧化镁90份，氯化镁60份，矿粉或镁质铝酸盐水泥10份，聚苯颗粒8份，疏水剂8份，改性剂1份，憎水粉2份，发泡剂0.5份，水65份。
根据以上工艺，具体制备方法为：
(1)将上述发泡剂溶于25份水中，搅拌均匀备用；
(2)按上述比例将氧化镁、氯化镁、矿粉或镁质氯酸盐水泥、聚苯颗粒、疏水剂、改性剂、憎水粉、剩余水以及步骤(1)中配制好的发泡剂混合均匀；
(3)将步骤(2)配制好的原料加入模型，摊平，由滚压机进行第一次滚压，形成初板，即聚苯颗粒无机保温层，厚度为20-120mm；
(4)在防护面层面上涂上粘合剂，防护面层厚度为0.6-0.9mm，将其铺设到所得的聚苯颗粒无机保温层的底部上，由滚压机进行第二次滚压，料体经自然干燥后切割打包，得聚苯颗粒无机保温板。
所述的原料中同时选用氧化镁和氯化镁，是因为氧化镁和氯化镁均为无机阻燃材料，两者同时组合使用用以提高阻燃效果从而提高防火性能；矿粉或镁质铝酸盐水泥具有良好的防火性能，与氧化镁和氯化镁混合使用从而使保温板达到A级防火要求，在使用中选择矿粉或镁质铝酸盐水泥其中一种；所述的聚苯颗粒为膨胀聚苯乙烯泡沫颗粒，保温效果好、价格便宜但阻燃效果差，与无机阻燃材料复配使用两者性能互补，协同作用，从而使得本发明的无机保温板既有较好的防火性能又具有保温性；所述的疏水剂为本技术领域现有技术中所用常规用料可以是HJ-F1活化性改性疏水剂；所述的改性剂、憎水粉、发泡剂均为本技术领域现有技术中所用常规用料，改性剂、憎水粉、发泡剂的加入使得聚苯颗粒和无机材料更好的混合，混合均匀发挥其性能，并能牢固的结合压板。
所述的聚苯颗粒无机保温板的聚苯颗粒无机保温层和防护面层之间的粘合剂为现有技术常规用料。
所述的聚苯颗粒无机保温层厚度根据客户需求可设为20-120mm，厚度太薄保温效果太差，厚度达到一定程度后保温效果提升不明显而且厚度太厚则增加成本，综合考虑将厚度设置为20-120mm。所述的防护层面为网格布或无纺布，均为现有技术中常用材料。
所述的聚苯颗粒无机保温板的制备方法中所使用的机械设备均为现有技术中常用设备。
本发明的有益效果：本发明提供了一种聚苯颗粒无机保温板及其制备方法，利用无机阻燃材料与矿粉或镁质铝酸盐水泥、聚苯颗粒结合为原料，在改性剂及发泡剂的作用下，经过滚压、成型和铺设饰面板生产而成，大大提高了保温板的防火等级和保温性能；本发明的生产方法，工艺简单、投资少、成本低。
