High-performance silicon dioxide vacuum insulation panel core material
The invention discloses a high-performance silicon dioxide vacuum insulation panel core material which structurally comprises a core material body, the core material body comprises hydrophilic silicon dioxide, an opacifying agent and a fiber material, the core material body is of a nanoscale microstructure, the hydrophilic silicon dioxide is modified through heat treatment, and the hydrophilic silicon dioxide with the low moisture absorption amount is obtained. The hydrophilic silicon dioxide in the core material has low moisture absorption capacity, and can effectively protect the microstructure of the hydrophilic silicon dioxide, so that the core material has a small nanoscale microstructure, and the heat insulation performance of the core material is improved.
本发明公开了一种高性能二氧化硅真空绝热板芯材，其结构包括芯材，芯材包括亲水二氧化硅、遮光剂、纤维材料，芯材为纳米级微观结构，亲水二氧化硅经过热处理改性得到吸湿量低的亲水二氧化硅，本发明芯材中的亲水二氧化硅具有较低的吸湿量，能够有效保护亲水二氧化硅的微观结构，从而使得芯材具备较小的纳米级微观结构，提高了芯材的隔热性能。
