Preparation method of anti-buffering silicon dioxide aerogel heat insulation sheet
The invention belongs to the field of heat insulation materials, and discloses a preparation method of an anti-buffering silicon dioxide aerogel heat insulation sheet. The preparation method comprises the following steps: cutting a felt body according to actual application requirements in a fiber felt stage, and combining the felt body with an anti-buffering part silicon rubber frame; and then, finishing the preparation process of the anti-buffering aerogel heat insulation sheet according to the processes of sol-gel, drying and packaging, so that the phenomenon that a large amount of aerogel powder falls off in the processes of cutting aerogel roll felt and packaging functional components in the traditional preparation process is avoided, and the conditions that the heat insulation performance of the aerogel heat insulation component is reduced and the distribution is not uniform are influenced to a certain extent. The anti-buffering aerogel heat insulation sheet obtained through drying is directly packaged, so that the powder falling problem existing in the existing aerogel sheet preparation process is effectively solved, and high packaging efficiency is achieved.
本发明属于隔热保温材料领域，公开一种抗缓冲二氧化硅气凝胶隔热片的制备方法：本发明在纤维毡阶段根据实际应用需求对毡体进行裁切并与抗缓冲部件硅橡胶框组合，然后按照溶胶‑凝胶、干燥及封装过程完成抗缓冲气凝胶隔热片的制备过程，避免了传统制备工艺中针对气凝胶卷毡在裁切以及在功能构件的封装过程中造成大量的气凝胶粉脱落现象，并一定程度影响气凝胶隔热构件的隔热性能降低、分布不均匀等情况。本发明对干燥得到的抗缓冲气凝胶隔热片直接进行封装处理，有效的解决了目前气凝胶片制备过程中存在的掉粉问题，并实现了高效的封装效率。
