Description

一种高效真空隔热板
技术领域
本发明涉及隔热板领域，特别是涉及一种高效真空隔热板。
背景技术
真空隔热板通常用在制冷器中，如冰箱、低温冷柜，通过设置在制冷器箱室的外表面和内表面之间来增加隔热效果以提高制冷效率。
具体地，真空隔热板包括芯材、密封层和吸气剂，其中芯材具有由玻璃纤维、粉末硅石或发泡聚氨酯形成的板，其内部保持真空；密封层用于密封和覆盖芯材以保持芯材的真空；吸气剂通过除去穿过密封层流入到密封层内的气体从而使真空隔热板的高真空度也就是隔热性能保持足够长的时间。
但现有真空隔热板单独应用于制冷器中作为隔热材料时，存在成本高、结构强度低、重复利用性能差等缺点，一旦制冷器报废，隔热材料不能回收利用。
发明内容
本发明主要解决的技术问题是提供一种复合型高效真空隔热板，能够解决现有真空隔热板应用在制冷器上存在的不足之处。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种高效真空隔热板，自内向外依次包括：芯材、吸收增强层、泡沫层、密封层和结构支撑层；
所述芯材为玻璃棉；
所述吸收增强层为碳纤维和玻璃纤维混合毡；
所述泡沫层的厚度占所述真空隔热板整体厚度的1/2～2/3；
所述密封层为包括镀在所述泡沫层外表面的镀铝层和位于所述镀铝层外侧的铝箔层；
所述结构支撑层为铝板层或钢板层。
在本发明一个较佳实施例中，所述碳纤维和玻璃纤维的混合比为3～5:1～2。
在本发明一个较佳实施例中，所述泡沫层为泡沫聚氨酯层。
在本发明一个较佳实施例中，所述镀铝层于所述铝箔层的厚度比为1～3:10。
在本发明一个较佳实施例中，所述结构支撑层的厚度为0.5～5mm。
本发明的有益效果是：本发明一种高效真空隔热板，结构简单，设计合理，成本低廉，其通过吸附加强层和结构支撑层的设计，提高了真空隔热板的整体强度，提高了真空隔热板的使用寿命，也便于回收利用。
附图说明
图1是本发明一种高效真空隔热板的立体结构示意图。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1，本发明实施例包括：
实施例1
一种高效真空隔热板，自内向外依次包括：芯材1、吸收增强层2、泡沫层3、密封层4和结构支撑层5；
所述芯材为玻璃棉；
所述吸收增强层为碳纤维和玻璃纤维以3～5:1～2的重量比例混合的毡层，该混合毡层的制备方法为：向碳纤维和玻璃纤维按重量比例混合均匀，然后放入压制机机内以2～10MPa的压力压制3～6h，使之成为层状毡结构；毡状结构中的碳纤维用于吸收气体，并和玻璃纤维共同起到增强的作用；
所述泡沫层为聚氨酯泡沫层，其厚度占所述真空隔热板整体厚度的1/2～2/3，起到增强隔热保温的作用；
所述密封层为包括镀在所述泡沫层外表面的镀铝层和位于所述镀铝层外侧的铝箔层；且镀铝层于所述铝箔层的厚度比为1～3:10；在聚氨酯泡沫层的外表面直接镀附铝层，可以有效增强密封、保温的作用；
