Abstract

The invention belongs to the technical field of heat insulation, and discloses a heat insulation composite board and a preparation method thereof. The heat insulation composite board comprises a firstpanel layer and a heat insulation layer, and the heat insulation layer and the first panel layer are integrally formed; the first panel layer is a fiber reinforced resin-based composite sheet, a metal plate, a cement plate, a calcium silicate plate or a gypsum plate, and the heat insulation layer is a fiber reinforced aerogel felt. The preparation method comprises the following steps of: (1) flatly laying a fiber-reinforced aerogel felt; (2) paving the first panel layer on the upper surface of the fiber reinforced aerogel felt; and (3) carrying out hot press molding treatment to obtain the heat insulation composite board. The heat insulation composite board provided by the invention can implement a thermal insulation scheme on scenes like pipes, walls and box bodies, and has the advantages of convenient operation, simplicity, feasibility and the like.

Description

technical field [0001] The invention belongs to the technical field of heat insulation, and in particular relates to a heat insulation composite board and a preparation method thereof. Background technique [0002] Airgel is a kind of porous material with nano-scale pore size, the typical pore size is between 1-100nm, the porosity is over 80%, and it contains a lot of air. The nano-porous structure of airgel makes the thermal conductivity of the material extremely low, and the thermal insulation effect is good. [0003] Due to its low specific gravity and thin pore walls, airgel is brittle and has poor direct use strength. Now industrialized airgel includes airgel cloth, airgel paper, airgel plate, airgel felt and other airgel special-shaped parts. Because of its unique thermal insulation properties, airgel composite materials are generally used as protective materials for sandwich structures. Sandwich structure panels usually include panel layers and sandwich layers. The ...
