Reusable wave-transparent heat-insulating aerogel material and preparation method thereof
The invention discloses a reusable wave-transparent heat-insulating aerogel material and a preparation method thereof, the process is simple, a high-temperature-resistant hydrophobic aerogel composite material is prepared by adopting an in-situ method, the formula is simple and easy to regulate and control, and complicated process steps are not added; compared with a surface post-treatment method, the prepared reusable wave-transparent heat-insulating aerogel material is controllable in hydrophobic effect, controllable in formula and good in hydrophobic uniformity. The reusable wave-transparent heat-insulation aerogel material is resistant to high temperature, the prepared composite material still has a good hydrophobic effect after being subjected to heat treatment in a muffle furnace at the temperature of 550 DEG C for 2 h, the mass loss rate is smaller than 1.3%, the mass moisture absorption rate is only 0.69%, and the hydrophobic angle is larger than 140 degrees.
本发明公开了一种可重复使用透波隔热气凝胶材料及其制备方法，工艺简单，采用原位法制备耐高温疏水气凝胶复合材料，配方简单易调控，未增加繁杂的工艺步骤；相较于表面后处理法，制备的可重复使用透波隔热气凝胶材料，疏水效果可控，配方可控，疏水均匀性较好。所述的一种可重复使用透波隔热气凝胶材料耐高温，将制得的复合材料置于550℃、2h马弗炉中热处理，仍有较好的疏水效果，质量损失率小于1.3％，质量吸湿率仅为0.69％，疏水角大于140°。
