Description
Technical Field
The invention belongs to the technical field of aerogel felt preparation, and particularly provides equipment and a method for preparing aerogel felts in a large scale.
Background
The aerogel felt is a flexible heat-preservation felt which is formed by compounding nano silicon dioxide or metal aerogel serving as a main body material with carbon fiber or ceramic glass fiber cotton or pre-oxidized fiber felt through a special process. It features low heat conductivity, certain tensile and compressive strength, and belongs to a new type of heat insulating material.
With the wide requirements and applications of heat preservation and energy conservation in various fields, the application range of the aerogel felt is continuously expanded, and the quality requirement of the aerogel felt is also continuously improved. Currently, aerogel blankets are produced in large batches and on a large scale.
Application No. 202080045596.0 discloses an aerogel blanket made by the following manufacturing method: 1) adding a catalyzed sol and a felt substrate to a reaction vessel to impregnate the catalyzed sol into the felt substrate; and 2) gelling the mat substrate impregnated with the catalyzed sol while rotating the mat substrate.
In terms of the selection of sol, the solvent of the aerogel sol needs to satisfy the condition of excellent compatibility with the sol precursor and water. Generally, when considering miscibility with water and subsequently prepared aerogels, solvents such as methanol, ethanol, etc. can be used, and slow gelation and volatilization of the solvent during gelation are one of the disadvantages of mass production of aerogel blankets.
Accordingly, there is a need in the art for an apparatus and method for scale-up production of aerogel blankets to address the above-mentioned problems.
Disclosure of Invention
In order to solve the problems, the invention provides equipment and a method for preparing aerogel felts on a large scale, so that continuous gum dipping and aging of fiber felts are realized, and volatilization of sol solvents can be reduced in large-scale production.
On one hand, the invention provides equipment for preparing aerogel felts in large scale, which comprises a conveying mechanism, and a glue solution loading mechanism and an airtight film layer which are arranged on the conveying mechanism;
the conveying mechanism comprises a rack and a conveying part arranged on the rack, the conveying part comprises a conveying belt and a driving part for driving the conveying belt to convey, and the conveying belt is provided with a heating belt capable of heating;
the glue solution loading mechanism carries out glue solution loading treatment on the fiber felt body to obtain a wet fiber felt;
the air impermeable membrane layer covers the wet fiber mat surface at the conveyor belt.
The technical effect of the scheme is as follows: the equipment can realize continuous gum dipping and aging of the fiber felt body, carry out film coating after the fiber felt is gum dipped, reduce the volatilization of alcohol solvent in sol, realize heat preservation from gum dipping to gel process and improve the product quality of aerogel felt.
In the preferable technical scheme of the equipment for preparing the aerogel felt on a large scale, the air-proof film layer is an annular film material, and the air-proof film layer performs closed-loop circulating motion above the conveyor belt through a film covering mechanism.
