Problems solved by technology

Generally, it is necessary to coat the surface of the enclosure with a thermal insulation layer to prevent the rapid transfer of heat to the room. The traditional thermal insulation layer is very thick and covers the panel surface, which affects the color, luster and other appearance indicators of the panel itself.
In addition, as the use time increases, impurities such as dust particles and harmful substances such as bacteria will adhere to the outer surface, but it is difficult to detect; and because the insulation building boards are generally hung high, cleaning is extremely troublesome, so the existing insulation Thermal building panels are seldom cleaned regularly; with the increase of use time, the surface of thermal insulation building panels is prone to fogging and darkening, which affects the aesthetics of the product

Embodiment 1

[0022] Such as figure 1 , image 3 As shown, the heat-insulating building board of this embodiment is a roofing board, and its cross-sectional structure includes a substrate 1, and a heat-insulating layer 2 is attached to one side of the substrate 1, and the heat-insulating layer 2 contains airgel , the substrate 1 is an aluminum alloy plate, which has the advantages of light weight and corrosion resistance, and the heat insulation layer 2 includes 80% by volume of paint and 20% by volume of aerogel, and the airgel It is silicon aerogel, and of course it can also be other aerogels such as carbon aerogel or organic aerogel. The volume fraction of the aerogel can be 10-30%, and the coating is a water-soluble varnish, so The thickness of the heat insulation layer 2 is 25 μm, and its range can be 10-100 μm. After mixing the airgel with water-soluble varnish and stirring evenly, it can be directly brushed or sprayed on the aluminum alloy plate, and then it can be dried; The exter...

Embodiment 2

[0024] Such as figure 2 , Figure 4 As shown, the heat-insulating building board of this embodiment is a kind of exterior wall board. The heat-insulating layer 2 is in the form of a thin film, and the film is directly pasted on the surface of the substrate 1. The heat-insulating layer 2 also contains anatase nano-scale titanium dioxide, which has a high concentration of active ingredients and has a strong Oxidation-reduction ability, high chemical stability and non-toxic performance, with excellent bactericidal and antibacterial and degrading harmful gas performance, avoiding bacterial roaring, preventing mildew, and avoiding the secondary toxicity of traditional chemical disinfectants to environmental governance and the problem of irritation and poor persistence, the effect of purifying air and self-cleaning is good; the shape structure of the wall panel includes a wall base plate 21 and the first connecting portion 22 and the second connecting portion located on both sides...

Abstract

The invention discloses a heat insulation building board, which has the characteristics of good heat insulation effect, small thickness of heat insulation layer, aesthetic property and durability. The heat insulation building board comprises a substrate (1), wherein heat insulation layers (2) are attached to one or two side surfaces of the substrate (1); and the heat insulation layers (2) containaerogel. The heat insulation building board can be widely used in the field of building materials.

Description

technical field [0001] The present invention relates to an insulating building board. Background technique [0002] With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings, and their roofing systems naturally also adopt metal structure roofing systems. Composite metal roofing systems are more and more widely used in various industries, sports, entertainment, exhibition halls, retail supermarkets and other buildings. Metal roofing systems require the use of metal roof panels and metal wall panels, ie, insulating building panels. [0003] At present, thermal insulation building boards are used in a wide range of applications, and they have the advantages of durability and beauty. Generally, buildings have higher requirements for heat insulation, in order to avoid rapid an...
