Abstract
本实用新型公开了一种玻璃纤维板芯材VIP板,该VIP板包括芯材和真空保护层,真空保护层密封于芯材外部;其中:所述芯材由多层玻璃纤维板复合而成;所述真空保护层为铝箔玻纤袋;每层玻璃纤维板的厚度为1~3mm,层与层之间采用粘结剂粘结。该玻璃纤维板芯材VIP板其导热系数低,抗压强度大,且更易于与墙面的结合。
Description
技术领域
本实用新型涉及VIP板技术领域,具体涉及一种玻璃纤维板芯材VIP板。
背景技术
真空绝热板(Vacuum Insulated Panel,VIP)是一种新型、高效的保温材料,主要用于保温绝热、防火阻燃,如冰箱、深冷冰柜、医疗柜、船载工程冷库、矿难救生舱、建筑外墙、内墙保温等。它基于真空绝热原理,由芯部隔热材料和封闭的隔气薄膜组成,填充芯材与真空保护表层严密复合,可有效避免空气对流引起的热传递,导热系数大幅度降低,从而达到绝佳的保温效果。芯材是VIP板的核心技术之一,除了要求具有结构支撑作用、具有低的导热系数外,在开孔率、开孔孔径、芯材放气和芯材的预处理等方面也有要求。现有VIP板(真空绝热板)芯材都使用单层材料制成,例如玻璃纤维棉、酚醛、聚氨酯或硅粉。每一种材料都有其优缺点。单一玻璃纤维做芯材失效(漏气)后膨胀,容易胀破墙面;酚醛、聚氨酯类属于有机保温材料只能依靠阻燃剂防火,但阻燃剂经长时间风化和分解其阻燃性能也降低,有机产品容易老化;硅粉失效(漏气)后粉末会下坠使保温板上部形成空洞形成无保温材料地带而冻墙,下部由于粉末的下坠使得下部鼓起胀破墙面形成安全隐患。
实用新型内容
本实用新型的目的在于克服现有VIP板存在的不足之处,提供一种玻璃纤维板芯材VIP板。所制备的VIP板其硬度高,更易于与墙体的结合,且施工方便。
为实现上述目的,本实用新型采用的技术方案是:
一种玻璃纤维板芯材VIP板,该VIP板包括芯材和真空保护层,真空保护层密封于芯材外部;其中:所述芯材由多层玻璃纤维板复合而成;
每层玻璃纤维板的厚度为1~3mm,层与层之间采用粘结剂粘结;所述粘结剂为聚氨酯胶粘剂。
所述真空保护层为铝箔玻纤袋,真空保护层内部的真空度为5×10-3~1×10-1Pa。
上述玻璃纤维板芯材是将玻璃纤维原材料,用挤压设备挤压玻璃纤维,使其挤压成1~3mm的板,然后在其板面上喷洒粘结剂,在喷酒粘接剂的表面上再放入玻璃纤维原材料,再挤压成型,如些循环,直至玻璃纤维板全部复合,达到所需的厚度。
本实用新型有益效果如下:
1、本实用新型采用多层玻璃纤维复合作为VIP板的芯材,其强度大,抽真空时,VIP板芯材受挤压变形量小,保证了板面的平整度。
2、本实用新型VIP板易于与墙体的结合且施工方便。
附图说明
图1为本实用新型VIP板结构示意图;其中:1-真空保护层;2-玻璃纤维板;3-粘结剂。
具体实施方式
下面结合附图及实施例详述本实用新型。
如图1所示,本实用新型VIP板包括芯材和真空保护层1,真空保护层1密封于芯材外部;所述芯材由多层玻璃纤维板2复合而成(本实施例为三层);
每层玻璃纤维板2的厚度为1~3mm,层与层之间采用粘结剂3粘结。
所述真空保护层1为铝箔玻纤袋,真空保护层内部的真空度为5×10-3~1×10-1Pa。
上述玻璃纤维板芯材是将玻璃纤维原材料,用挤压设备挤压玻璃纤维,使其挤压成1~3mm的板,然后在其板面上喷洒粘结剂,在喷酒粘接剂的表面上再放入玻璃纤维原材料,再挤压成型,如些循环,直至三层玻璃纤维板全部复合。本实用新型VIP板使用过程中与墙面结合良好,长久使用无膨胀等问题出现。
