Aerogel fiber felt and preparation method thereof
The invention discloses an aerogel fibrofelt and a preparation method thereof. The method comprises the following steps: providing a fibrofelt, placing a plurality of space occupying molds arranged at intervals on the fibrofelt, pouring a molding agent into the space occupying molds, forming pre-occupied spaces arranged at intervals on the fibrofelt, filling gaps between the adjacent pre-occupied spaces with aerogel slurry, and forming the aerogel fibrofelt. After sufficient curing, drying is carried out, the molding agent in the pre-occupied position is removed, the occupied position mold is taken out from the fiber felt, and the aerogel fiber felt is prepared; according to the invention, the aerogel is adopted as a main body material and is compounded with the fiber felt, so that the process can ensure that all the components are tightly combined, the material has better stability in the transportation and use process, the tensile strength and compressive strength of the material are improved, the possibility of particle falling and powder falling is reduced, and the compounding strength of the aerogel fiber felt is improved; the application range is greatly expanded, and mass production and commercialization are facilitated.
本发明公开了一种气凝胶纤维毡及其制备方法，所述方法包括：提供一纤维毡，在纤维毡上放置若干间隔排列的占位模，将造模剂浇置于占位模内，在纤维毡上形成间隔排列的预占位，将气凝胶浆料填充于相邻的预占位间隙，充分固化后进行干燥，去除所述预占位内的造模剂，并从纤维毡上取出占位模，制得气凝胶纤维毡；本发明，采用气凝胶作为主体材料，与纤维毡复合而成，这种工艺能够确保各组分之间紧密结合，在运输和使用过程中具有更好的稳定性，增加了材料的抗拉及抗压强度，减少了颗粒脱落及掉粉的可能性，气凝胶纤维毡的复合强度，也极大的扩展了其应用范围，有利于大批量生产和商业化。
