Description
Technical Field

Background
The method of preparing aerogel blankets from fibrofelt composite aerogels is a widely used process. The aerogel felt is a flexible felt body which is formed by compounding aerogel serving as a main body material with fiber felts such as carbon fibers, ceramic fiber cotton, glass fiber cotton, pre-oxidized fiber felts and the like. The aerogel felt has the advantages of low heat conductivity coefficient, high tensile strength and compressive strength and the like, and can be applied to various industrial fields such as pipeline heat preservation, new energy battery heat insulation and the like. Currently, aerogel felts are mostly produced in an intermittent manner, aerogel sol is usually soaked in a container in the form of fiber roll felts, for example, a dipping reaction kettle mentioned in patent CN202010665648.6, an aluminum silicate fiber felt is wound into a roll and mounted on a central shaft of a rotatable dipping reaction kettle, and a glue solution is injected into the dipping reaction kettle to realize the dipping of the fiber felt. However, in the manner of immersing the fiber mat in the aerogel sol in the container, since the container is reserved with a space for conveniently taking and placing the fiber mat, the volume in the container needs to be larger than the volume of the fiber mat, which causes two disadvantages: firstly, after the fiber mat is immersed by the aerogel sol, excessive aerogel sol in the container causes production waste; secondly, a large amount of excess aerogel sol is easily adhered to the container wall after being gelled, and a large amount of time is required for cleaning.
