Heat-insulation solidifiable thermosetting composite material and preparation method and application thereof

Abstract

The invention discloses a heat-insulation solidifiable thermosetting composite material. The heat-insulation solidifiable thermosetting composite material comprises a solidifiable thermosetting composite material prepreg sheet material, an adhesive film and a fiber composite core layer, wherein the adhesive film is adhered to the upper surface and / or the lower surface of the fiber composite core layer; the solidifiable thermosetting composite material prepreg sheet material is further adhered onto the other side face of the adhesive film; and the aerogel is adsorbed and poured in the fiber composite core layer. The invention also discloses a preparation method and application of the composite material. The composite material disclosed by the invention has relatively high puncture resistance so as to solve the defect that the aerogel poured and adsorbed in the fiber composite core layer is likely to escape or leak in the using process, so that the composite material has relatively high strength, rigidity and better sound insulation and heat insulation performances and can be used for cladding of tubular products, heat preservation of wall bodies or application of structural members such as cold storage body plates, and the application range of the aerogel material is expanded.

Description

technical field [0001] The invention belongs to the technical field of heat insulation, heat preservation and curable thermosetting, and particularly relates to a heat insulating curable thermosetting composite material and its preparation method and application. The heat insulating curable thermosetting composite material of the present invention is a curable poly layer composite material. Background technique [0002] Due to the static gas in the sandwich body, the airgel material has the characteristics of good sound insulation, heat insulation and light weight. Therefore, the airgel material is widely used in the field of industrial heat insulation. In addition, as Metal casings of thermal insulation materials are also widely used. [0003] The airgel material has a cylindrical multi-branched nanoporous three-dimensional network structure with high permeability, and has extremely high porosity, low density, high specific surface area, and ultra-high pore volume ratio, a...

Problems solved by technology

Chinese patent CN105058949A introduces "a manufacturing method of vacuum insulation panels", specifically: adding nano-airgel powder and calcium carbonate powder to glass fiber filaments, packing them in bags, and finally vacuumizing and sealing them. , but the strength, rigidity and other aspects of the plates made by this invention are difficult to meet the actual needs

[0004] In industry, the galvanized iron sheet is usually used as the outer protective layer of the airgel material. However, since the galvanized iron sheet is connected to the airgel insulation layer by riveting, the sealing of the two cannot be guaranteed, and external moisture can easily enter the airgel insulation layer. , resulting in corrosion of the airgel insulation layer and failure of heat preservation; at the same time, the galvanized iron sheet also has the defects of not being resistant to trampling and mechanical damage, and is easily damaged under the action of external force, causing the outer protective layer to be damaged
