Superfine glass fiber vacuum insulation panel

The invention relates to the technical field of heat insulation materials, and provides a superfine glass fiber vacuum heat insulation plate which comprises a core material and a gas barrier diaphragm bag, and the core material comprises the following raw materials in parts by weight: 40-60 parts of glass fiber, 20-30 parts of modified nano silicon dioxide, 30-40 parts of ceramic powder, 10-15 parts of a gas adsorbent and 5-10 parts of a drying agent; the modified nano silicon dioxide is obtained by modifying nano silicon dioxide with 4-hydroxyphenylethylamine to obtain modified nano silicon dioxide and then adding TiO2 for modification. By means of the technical scheme, the problem that in the prior art, the mechanical property and the heat resistance of a vacuum heat insulation plate core material are poor is solved. 本发明涉及绝热材料技术领域，提出了一种超细玻璃纤维真空绝热板，包括芯材和阻气隔膜袋，所述芯材包括以下重量份组分的原料：40~60份玻璃纤维、20~30份改性纳米二氧化硅、30~40份陶瓷粉、10~15份气体吸附剂、5~10份干燥剂；所述改性纳米二氧化硅为纳米二氧化硅经4-羟基苯乙胺进行修饰后，得到修饰后纳米二氧化硅，再加入TiO2进行改性得到。通过上述技术方案，解决了现有技术中真空绝
