Problems solved by technology

[0010] The thickness is very large, and it covers the board surface, which affects the appearance indicators such as the color and luster of the board 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

[0034] Such as figure 1 , image 3 As shown, the thermal insulation building panel of this embodiment is a roof panel, and its cross-sectional structure includes a base plate

[0035] 1. A thermal insulation layer 2 is attached to one side of the substrate 1, and the thermal insulation layer 2 contains airgel. The substrate 1 is an aluminum alloy plate, which has the advantages of light weight and corrosion resistance. The thermal insulation layer 2 comprises 80% by volume of paint and 20% by volume of aerogel, the airgel is silicon aerogel, and of course it can also be other aerogels such as carbon aerogel or organic aerogel. Gel, the volume fraction of the airgel can be 10-30%, the coating is a water-soluble varnish, the thickness of the heat-insulating layer 2 is 25 μm, and its range can be 10-100 μm. After the gel is mixed with water-soluble varnish and stirred evenly, it can be directly brushed or sprayed on the aluminum alloy plate, and it can be dried; Upright ribs 1...

Embodiment 2

[0037] Such as figure 2 , Figure 4 As shown, the heat-insulating building board of this embodiment is a kind of exterior wall board, and its difference from Embodiment 1

[0038] The feature is that: in this embodiment, both sides of the substrate 1 are attached with a thermal insulation layer 2, the thermal insulation layer 2 is in the form of a film, and the film is directly pasted on the surface of the substrate 1. The thermal layer 2 also contains anatase nano-scale titanium dioxide, which has a high concentration of active ingredients, has strong redox ability, high chemical stability and non-toxic performance under sunlight, and has excellent bactericidal and antibacterial and degrading harmful gas performance. , to avoid the bacteria growling, to prevent mold, to avoid the use of traditional chemical disinfectants on environmental governance secondary toxicity and irritation and poor persistence, and to purify the air and self-cleaning effect is good; the shape and s...

Abstract

The invention discloses a heat-insulated building board. The heat-insulated building board comprises a base board (1), and a heat insulation layer (2) containing aerogel is attached to one surface or each of two surfaces of the base board (1). The heat-insulated building board is good in heat insulation effect, small in heat insulation layer thickness, attractive and durable and can be widely applied to 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, gold [0003] Attribute packaging, etc. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings. [0004] The roof system naturally also adopts a metal structure roof system. Composite metal roofing system is widely used in various industries, sports, entertainment, [0005] It is more and more widely used in exhibition halls, retail supermarkets and other buildings. Metal roofing systems require the use of metal roof panels and metal [0006] Wall panels, etc., that is, thermal insulation building panels. [0007] At present, thermal insulation building boards are used in a wide range of applications, and they have the advantages of durability and beauty. General buildings have...
