Reflection heat insulation and preservation veneer integrated external wall panel sectional material

Abstract

The invention relates to a reflection heat insulation and preservation veneer integrated external wall panel sectional material which is composed of a heat preservation layer and a veneer layer, wherein the heat preservation layer and the veneer layer are pressed to form a whole. The heat preservation layer is an existing external wall external heat preservation sectional material product made of inorganic mineral materials in the market. The veneer layer is formed by preparing ten raw materials of waste stone detrital materials, hollow glass micro-beads, vitrified micro-beads, rare-earth oxides, rutile, waterborne emulsion, inorganic adhesives, wood fiber, polypropylene short fiber and film formation auxiliaries and water. An overall composed, pressed and formed structure of the heat preservation layer and the veneer layer is adopted for the sectional material, the structure is used for an external wall body, safety is high, solar radiant heat absorbed by a building can be reduced, temperature rising caused by solar radiation absorbed by the surface of the building is prevented, heat transmitted into a room is reduced, the heat preservation and insulation requirement of the building outer wall body is met, and the purposes of providing comfortable indoor and outdoor environments, saving energy and lowering consumption are achieved.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an exterior wall panel profile integrated with reflective heat insulation and decorative surfaces. Background technique [0002] Building thermal insulation and energy saving is one of the key points of my country's energy conservation work. With the further standardization of civil building energy-saving design "standards" and the implementation of the State Council's "Civil Building Energy Conservation Regulations", more and more new building materials and external wall thermal insulation systems have been proposed. Higher requirements require not only light weight, thermal insulation properties, but also outstanding compression, tensile, and anti-aging properties; reliable waterproof and impermeable properties, as well as fireproof, acid and alkali resistance, and anti-aging properties. Pollution performance must also meet the requirements...

AI Technical Summary

Problems solved by technology

[0003] 1) The load-bearing wall layer, heat insulation layer and decorative protective 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, which is easy to Cracking and falling off cause maintenance difficulties, the insulation layer cannot be effectively protected, the service life is short, and there are many safety hazards, and the paint finish is easy to fade and wrinkle, etc.

[0004] 2) The construction process of the insulation layer and the decorative layer is cumbersome, labor-intensive, and the construction period is long, and the quality is completely guaranteed by the quality of manual work. In addition, it is a hidden project. It is not easy to check and find out that the work is rough during the construction process, or even cut corners. , resulting in out-of-control construction quality and affecting the quality and service life of the thermal insulation system

[0005] 3) 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 construction is extremely unsafe, and the surface is easy to fade, which affects the aesthetic effect of the building

[0006] 4) The external decoration materials and construction cost of the wall are high and the construction period is long, which brings negative effects in many aspects such as comprehensive benefits and environmental impact

[0007] So far, although 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 Neither is ideal
