Abstract

The invention discloses an aerogel-based heat-insulating sound-absorbing multilayer composite board. The board comprises a composite board aerogel base layer, wherein a composite board aerogel side baffle is arranged above the composite board aerogel base layer, the composite board aerogel base layer and the composite board aerogel side baffle are integrally formed, a plurality of first through holes are evenly formed in a first carbon fiber felt board, and a plurality of second through holes are uniformly formed in the second carbon fiber felt board. According to the aerogel-based heat-insulating sound-absorbing multilayer composite board, through cooperation of the first carbon fiber felt board and the second carbon fiber felt board with different material characteristics, the sound-absorbing effect can be effectively achieved; through cooperation of the base layer, a decorative layer and a protective layer, the beautifying degree of the whole board is improved under the action of the decorative layer, the decorative layer is protected under the action of the protective layer, and the use experience of the board is improved; and the strength of the whole board is guaranteed whilethe weight of the whole board is reduced under the action of embedded grooves and reinforcing ribs.

Description

technical field [0001] The invention relates to the technical field of an airgel-based heat-insulating and sound-absorbing multilayer composite board, in particular to an airgel-based heat-insulating and sound-absorbing multilayer composite board. Background technique [0002] Airgel refers to a nano-scale porous solid material formed by using a certain drying method to replace the liquid phase in the gel with the gas through the sol-gel method. Such as gelatin, gum arabic, silica gel, hair, nails, etc. Airgel also has the properties of gel, that is, it has swelling effect, thixotropy effect, and slurry effect. Airgel is a solid form of matter, the smallest solid in the world. The density is 3 kilograms per cubic meter. The most common airgel is silicon aerogel. There are many types of aerogels, including silicon-based, carbon-based, sulfur-based, metal oxide-based, metal-based and so on. The sound absorption effect of the existing airgel-based multilayer composite pane...
