Inorganic heat-preserving metal facing one-piece type fire wall section material and its production method

Abstract

The invention relates to an integral fireproof wall profile for an inorganic insulating metal facing and a preparation method thereof. The wall profile is provided with an insulating layer and a facing layer, the insulating layer is formed by mixing and pressing inorganic insulating light aggregate and slurry, the facing layer adopts a metal sheet, and the insulating layer and the facing layer are adhered by adopting an adhesive and pressed to form an integral structure. The insulating layer of the wall profile is compounded by a plurality of natural inorganic mineral composite materials, so the wall profile has a plurality of good performances such as innocuity, tastelessness, incorruption, incombustibility, acid resistance, alkali resistance, heat isolation, heat preservation and the like, and is a comparatively ideal environment-friendly building material; and the metal facing is adopted, so the wall profile not only has good anti-flaming, fire-proof, water-proof and crack-resisting functions to protect a wall body and the insulating layer most ideally, but also has the sensorial effects of high-grade luxury and decorative beautified environment.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an inorganic thermal insulation metal facing integrated fire wall profile and a preparation method thereof. Background technique [0002] With the further standardization of civil building energy-saving design "standards" and the implementation of the State Council's "Regulations on Civil Building Energy Conservation", higher and higher requirements are put forward for new building materials and wall insulation systems, which require both good thermal insulation performance , but also have strong compressive, tensile, and anti-aging properties; it must not only have reliable flame-retardant, fire-proof, waterproof and impermeable properties, so that the wall has a longer overall service life, but also conform to green environmental protection and non-toxic Harmless requirements; at the same time, the development of social economy and the cont...

AI Technical Summary

Problems solved by technology

[0003] 1) The load-bearing wall layer, thermal insulation layer and facing protection layer are poorly bonded to each other, and the surface tiles only have a single decorative function, and their own weight is relatively large, thus increasing the overall weight of the wall, and It is easy to crack and fall off, making maintenance difficult, the insulation layer cannot be effectively protected, the service life is short, and there are many safety hazards, and the paint finish is prone to fading and wrinkling.

[0004] 2) Because organic materials are mostly used in the composite thermal insulation finish layer, a large amount of toxic gas is released during use, which seriously pollutes the environment. Especially this material has a low flame retardant coefficient and poor fire resistance, which is easy to cause fire, which is harmful to the economy and serious danger to the crowd

[0005] 3) The construction process of the insulation layer and the facing layer is cumbersome, labor-intensive, long construction period, high cost, and the quality is completely guaranteed by the quality of manual work. In addition, it is a concealed project, which requires rough work during the construction process, and even cut corners It is not easy to check and find, leading to out of control of construction quality and affecting the quality and service life of wall insulation

[0006] 4) The heat insulation, waterproof and self-cleaning performance of the facing layer is poor, and it is easy to be contaminated with dust and stains, especially for high-rise buildings. It is very difficult to clean and maintain, and the operation is extremely unsafe, and the surface is easy to fade, which affects the aesthetic effect of the building

[0007] 5) Since organic materials are difficult to be bonded with inorganic materials into a whole, expensive adhesives or barbed wire auxiliary fixing layers are required, which is not only difficult to construct, but also expensive, and it is easy to produce "thermal bridge" effects and reduce the thermal insulation effect

[0008] So far, although the relevant departments have made great efforts in building materials and construction technology, and have continuously developed various new insulation materials and technologies, the overall effect is not ideal.
