A fire-proof insulation board with aluminum profiles and injection-molded flame-retardant heat-conducting-heat-insulating components

Abstract

The invention provides a fireproof heat retaining panel with an aluminum profile and an injection molded antiflaming heat-conducting-heat-insulation component, and belongs to the field of fireproof heat retaining panels of building materials. The fireproof heat retaining panel is formed by a transparent self-cleaning film 1 which does not absorb infrared rays, the outer surface 2 of an aluminum profile housing 11, a first heat-insulation inorganic coating layer 3, an injection molded antiflaming heat-conducting-heat-insulation component 4, a second heat-insulation inorganic coating layer 5, and an expansion glass wool layer 6 wrapped by aluminum foil, and a third heat-insulation adhesive film layer 7. The outer surface 2 is provided with a triangular pit in angle of 15-60 DEG and the self-cleaning film. A principle of double-layer glass heat insulation is used to make the injection molded antiflaming heat-conducting-heat-insulation component, and a quasi-stationary air thermal insulating layer is formed between the heat retaining panel and a wall surface. The injection molded antiflaming heat-conducting-heat-insulation component 4 is a ladder type linked body formed by a plurality of groups of element components 43 with horizontal simply support mechanical beams (heat conducting isothermal subparts) 41 which have electroplating heat conducting metal layers and support beams (heat insulation subparts) 42 without electroplating heat conducting metal layers. The coating layer 3 and the adhesive film layer 7 are formed by foaming inorganic adhesives.

Description

technical field [0001] The invention relates to a fire-proof heat-preservation board, in particular to a fire-proof heat-preservation board with an aluminum profile and an injection-molded flame-retardant heat-conducting-heat-insulation component, which belongs to the technical field of fire-proof heat preservation boards for building materials. The technology adopted in the present invention is completely different from the current idea of ​​improving the heat insulation and heat preservation technology of the fireproof heat preservation board. The laws of thermodynamics, especially according to the knowledge of Fourier's law of heat and Newton's law of cooling, use one or more layers in the closed space of the hollow aluminum profile to be perpendicular to the direction of heat flow (for example: the direction perpendicular to the wall or parallel direction) Injection-molded flame-retardant heat-conducting-heat-insulating components (with a still air layer inside) that can i...

AI Technical Summary

Problems solved by technology

[0009] 2. The existing technology either simply pursues mechanical strength or mechanical toughness and beautiful appearance, ignoring light weight and thermal bridge problems, or simply pursues excellent heat insulation properties, ignoring wind and snow resistance, fire prevention, and moisture resistance

Therefore, under certain cost constraints, it is difficult for most protective panels of external wall fireproof and thermal insulation panels to achieve the perfect combination of high mechanical strength, good mechanical toughness and excellent heat insulation, wind and snow resistance, fire prevention, moisture resistance and low cost.

Therefore, it is difficult to work hard on the protective plate of the current fireproof insulation board of the outer wall, and the practicability is not good.

[0010] 3. At present, most of the external wall fire-proof and thermal insulation boards in China use cement concrete boards, glass magnesium boards, etc., which have strong heat absorption capacity and large heat capacity. They absorb a lot of heat during the day in summer, and the accumulated heat Radiates strongly, causing localized overheating

[0011] 4. At present, in China, the best use of the air layer to improve the heat insulation of the external wall fire insulation board is not enough or the limitation of understanding

[0016] 5. The thickness of the protective board and the increase in the thickness of the heat insulation and insulation layers are not only limited by the cost, but also restricted by the requirements for wind and snow resistance and the life characteristics of the external wall fire insulation board

[0019] Existing aluminum profiles usually only pay attention to the compactness and adhesion process between the surface of the aluminum profile and the corrosion-resistant film on the outer surface, without in-depth research on the hydrophilicity of the corrosion-resistant film on the outer surface
