Description
技术领域
本发明属于绝热保温领域,涉及一种内墙用保温系统材料,特别涉及一种内墙用真空绝热板材衍生品及其制备方法。
背景技术
《中华人民共和国节约能源法》、《民用建筑节能管理条列》、《关于进一步推进墙体材料革新和推广节能建筑的通知》、《关于新建居住建筑严格执行节能设计标准的通知》等政策提出了国家节能目标:2011年,城镇建筑达到节能50%的设计标准,其中特大城市和部分大城市率先实施节能65%的设计标准。同时国家新推出了有力的节能政府补贴政策、绿色建筑标示,可见我国政府对建筑节能保温的重视和严格。
以前,我国采用挤塑聚苯乙烯泡沫塑料、模塑聚苯乙烯泡沫塑料(EPS)、硬质聚氨酯泡沫塑料(PU)等有机质绝热材料作为外墙外保温材料。但这些材料具有易燃的特性,这使得目前建筑设计施工中普遍存在安全隐患,近几年已逐渐被A级阻燃材料所替代。
在A级阻燃材料中,真空绝热板具有最低的导热系数,其中干法制备的真空绝热芯材具有最佳导热性能,能够实现同等绝热效果下的超薄厚度。但传统的外墙外保温施工方式极其复杂,且受气候影响,成本高,安全性低。若直接用于内墙易出现破损、胀裂等,因此,需要对真空绝热板芯材进行深加工,使其适用于内墙内保温系统。
发明内容
有鉴于此,本发明的目的在于提供一种内墙用真空绝热板材衍生品及其制备方法。
为达到上述目的,本发明提供如下技术方案:
1、一种内墙用真空绝热板材衍生品,所述真空绝热板材衍生品由粘结层、保温层、填充层、防护层、饰面层组成,所述粘结层为铝箔,所述保温层为真空绝热板材,所述填充层为硬质泡沫塑料,所述防护层为金属框结构,所述饰面层为阻燃牛皮纸。
进一步,所述真空绝热板材外部与铝箔粘贴为一体再置于金属框内并留存空隙,空隙填充硬质泡沫塑料,在金属框外一侧粘接阻燃牛皮纸。
进一步,所述真空绝热板材采用如下方法制得:
1)离心喷吹法制备超细玻璃纤维棉,干法热熔成型,其纤维直径分布在1-3um,克重为 1.8~2.0kg/m2;
2)将芯材装入铝合金多层高阻隔薄膜,并加入吸气剂,抽真空。
进一步,所述防护层为镀锌铜板、镀锌钢板、热镀锌彩钢板、电镀锌彩钢板、镀铝锌彩钢板中任一种。
进一步,所述硬质泡沫塑料为聚苯乙烯泡沫塑料、聚氨酯泡沫塑料、聚氯乙烯泡沫塑料中的任一种或几种。
进一步,所述阻燃牛皮纸由玻璃纤维网格与阻燃牛皮纸复合而成。
2、所述内墙用真空绝热板材衍生品的制备方法:
1)将真空绝热板材置于金属框内侧,真空绝热板紧靠粘结层,与防护层之间留存5~6mm 缝隙;
2)在金属框内缝隙处填充硬质泡沫塑料,使真空绝热板得到固定;
3)在饰面层粘接阻燃牛皮纸,玻纤网格面朝内,牛皮纸面朝外。
本发明的有益效果在于:该真空绝热板材衍生品的优势在于:①A级防火优势:采用无机材料制成,燃烧性能A1级,属不可燃材料;②高效节能优势:超强的隔热保温性能,导热系数在0.0025w/(m.k)左右,节能效果突出;③重量轻质优势:保温效果是其他传统保温材料的2-15倍,所需保温厚度是传统保温的1/3至1/8;④环保低碳优势:采用无机、无 毒芯材,低能耗零排放加工工序,不产生废气、废水,属环保低碳型保温材料;⑤施工便捷优势:轻质的特点,运输、搬运方便,施工工艺简单;⑥使用寿命优势:超高阻隔复合膜,透氧、透水率极低;玻璃微纤维芯材性能稳定、不释放气体;吸气剂或真空稳定剂能使真空绝热板达到30年以上的设计寿命。
