Description

一种真空绝热板及其制造方法
技术领域
本发明属于建筑领域,尤其涉及一种真空绝热板的保温芯材,属于E04B领域。
背景技术
现有真空绝热保温板主要由外覆高阻气膜与内部隔热芯材构成,隔热芯材一般采用常规保温材料、玻璃纤维与气凝胶等组合制成,缺点为材料成本高,能耗高,不环保。
发明内容
针对目前现有技术的缺点,本发明的目的是提供一种真空绝热保温板芯材及其制作方法,解决现有市场产品材料成本高,能耗高的缺点。
为了实现上述目的,本发明的技术方案如下:一种真空绝热板,包括芯材和高阻气复合膜,在所述芯材至少包括多层无机纤维层,所述多层无机纤维层是上下堆叠或者通过粘结剂上下连接,所述多层无机纤维层中的至少两层的无机纤维层的密度或成分不同。
作为优选,玻璃纤维层的层数为3-100层。进一步优选为5-50层。
作为优选,无机纤维的密度为10-300kg/m3
作为优选,任意相邻两层的无机纤维层的密度或成分不相同。
作为优选,沿着上部往下,无机纤维层的密度增加或者依次减小。
作为优选,沿着上部往下,无机纤维层的长径比依次增加或者依次减小的幅度越来越小。
作为优选,其中密度大的层和密度小的层交替设置。
作为优选,所述的无机纤维层是玻璃棉纤维板、硅酸铝纤维板、离心玻璃棉板、岩棉板、废纸浆、纺织纤维板中两种以上交替设置。
与现有技术相比较,本发明的真空绝热保温芯材具有如下的优点:
1)无机纤维不易燃烧,本身导热系数低,可满足国家六五节能规划的需要。芯材不掺加其他粉末类保温填料,增加了保温板的强度,提高了真空稳定性,能达到较低的导热系数。原材料价格低廉,保证一定的导热系数,降低了原料成本,减少了对环境的污染。
2)采用密度或成分不同的无机纤维层作为真空绝热板的芯材,性能高,绝热系数有了很大提高,使真空绝热板的厚度大大降低。
3)将芯材分为多层,即增加了芯材的强度,又可以增加芯材的可替换性,即当芯材某一层损毁时,其余层可以重复再次利用。
4)提供了一种玻璃纤维层的制作方法,通过该方法,可以制造出非常适合真空绝热板的芯材,从而降低了真空绝热板的造价。
附图说明
图1为本发明的真空绝热板芯材的示意图。
具体实施方式

请注意,此处的多层无机纤维层包括2层以及2层以上。
作为优选,其中芯材包括覆盖无机纤维层的上层区和/或位于无机纤维层下部的下层区。
作为优选,上层区和/或下层区由硅酸铝纤维板、离心玻璃棉板、岩棉板、纺织纤维板、废纸浆板中的一种或多种制成。
作为优选,无机纤维层的层数为3-100层。进一步优选为5-50层。
作为优选,无机纤维的密度为10-300kg/m3
作为优选,任意相邻两层的无机纤维层的密度或成分不相同。
作为优选,沿着上部往下,无机纤维层的密度增加或者依次减小。通过实验证明,密度依次增加或者依次减少所带来的隔热效果更好,能够达到较优化的隔热效果,能够提高10%左右的隔热效果。
作为优选,沿着上部往下,无机纤维层的密度依次增加或者依次减小的幅度越来越小。通过实验证明,无机纤维层的密度依次增加或者依次减少的幅度越来越小所带来的隔热效果更好,能够达到更优的隔热效果。
作为优选,其中密度大的层和密度小的层交替放置。通过实验证明,此种放置隔热效果很好,能够提高7.3%以上的隔热效果。作为优选,密度大的层的密度为100-300kg/m3,密度小的密度为10-100 kg/m3,选择此条件下的密度会达到更优的绝热效果。
作为优选,超细玻璃棉纤维板,体积密度为10kg/m3­-100 kg/m3,厚度为1mm-9mm。

将绝热板芯材或者与其他层互相结合形成真空绝热板芯材;
将绝热保温板芯材放入高阻气复合膜袋中,然后通过抽真空的方式,得到真空绝热板。
