Vacuum insulated panel core material and preparation method thereof, vacuum insulated panel and preparation method thereof
The invention belongs to the technical field of heat insulation materials, and discloses a vacuum insulated panel core material and a preparation method thereof, and a vacuum insulated panel and a preparation method thereof. The vacuum insulated panel comprises a core material, a protective layer and a barrier film, wherein the core material is prepared from the following raw materials in parts by weight: 50-70 parts of glass fibers, 8-15 parts of fumed silica, 10-20 parts of straw powder, 2-7 parts of an opacifying agent and 1-6 parts of a getter; and the protective layer is made of superfine glass wool. The fumed silica is added into the vacuum insulated panel core material, the heat insulation effect is improved, meanwhile, the mechanical property and stability of the vacuum insulated panel are improved due to the existence of the glass fibers, and the service life is prolonged due to the arrangement of the protective layer and the barrier film. The prepared vacuum insulated panel has the advantages of lower heat conductivity coefficient and shrinkage rate, higher mechanical property and stability, lower raw material price and easiness in industrial large-scale production.
本发明属于隔热保温材料技术领域，公开了一种真空绝热板芯材及制备方法和真空绝热板及制备方法。该真空绝热板包括芯材、保护层和阻隔膜；其中芯材的原料为玻璃纤维50～70份，气相二氧化硅8～15份，秸秆粉10～20份，遮光剂2～7份，吸气剂1～6份；保护层为超细玻璃棉。本发明的真空绝热板芯材中加入了气相二氧化硅，提高了隔热效果，同时玻璃纤维的存在也提高了真空绝热板的力学性能和稳定性，保护层以及阻隔膜的设置延长了使用寿命。制得的真空绝热板具有较低的导热系数和收缩率、较高的力学性能以及稳定性，同时原材料价格相对低廉，易于工业化大规模生产。
