Pretreatment method of glass needled felt base material for aerogel
The invention discloses a pretreatment method of a glass needled felt base material for aerogel, which specifically comprises the following steps: laying a plurality of layers of glass fibers to form a first glass fiber layer, and uniformly spraying inorganic powder on the first glass fiber layer to form an inorganic powder layer; a plurality of layers of glass fibers are laid on the inorganic powder layer again to form a second glass fiber layer, and a glass needled felt base material of a sandwich structure is formed; and finally, immersing the glass needled felt base material into the aerogel glue solution to obtain the aerogel glass fiber material.
本发明公开了一种气凝胶用玻璃针刺毡基材的预处理方法，具体包括如下步骤：先铺设多层玻璃纤维形成第一玻璃纤维层，然后在第一玻璃纤维层的上方均匀喷撒无机粉末形成无机粉末层，再在无机粉末层的上方再次铺设多层玻璃纤维形成第二玻璃纤维层，形成具有夹心结构的玻璃针刺毡基材；最后，将玻璃针刺毡基材浸入气凝胶胶液中进行浸泡，得到气凝胶玻璃纤维材料。
