Integrated nano inorganic wall light heat insulation facing section bar and preparation thereof

Abstract

The invention relates to an integrated type nano inorganic wall light weight heat preservation veneer and a method for preparing the same. The veneer consists of a heat preservation substrate which is formed by the one-piece pressure moulding of a plurality of inorganic mineral materials and a veneering layer, wherein the heat preservation substrate is prepared by husk type expanded perlite light-weight aggregate, cement, silicon oxide micropowder, wood fiber micropowder, organosilicon emulsion and cement reinforcing agent according to the blending ratio; the veneering layer is prepared by quartz sand, calcium carbonate, cement, silicon oxide micropowder and wood fiber micropowder according to the blending ratio and is in one-piece pressure moulding. Compaed with prior art, the veneer has the advantages of light weight, high strength, good heat insulation and heat preservation effects, tight bonding, energy conservation and environmental protection, resource conservation, easy construction, short construction period, low cost and long service life, etc.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an integrated nano-inorganic wall lightweight thermal insulation decorative surface profile and a preparation method thereof. Background technique [0002] With the further standardization of the "standards" for energy-saving design of civil buildings and the implementation of the State Council's "Regulations on Energy Conservation of Civil Buildings", higher requirements are put forward for new building materials and wall insulation systems, which require both good thermal insulation performance and It has outstanding compressive, tensile, and anti-aging properties; it must not only have reliable protective properties to fundamentally block fire hazards, but also have the characteristics of waterproof, impermeable, and permanent service life; it must be green and environmentally friendly, non-toxic and non-toxic. Harmful, but also beautiful ...

AI Technical Summary

Problems solved by technology

[0003]1) The load-bearing wall layer, thermal insulation layer and decorative protective layer are poorly bonded to each other, and the surface tiles only have a single decorative function. The self-weight is large, which increases the overall weight of the wall, which 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 easy to fade and wrinkle. wait

[0004]2) The construction process of the insulation layer and the facing layer is cumbersome, labor-intensive, and the construction period is long. The quality is completely guaranteed by manual work, and it is concealed. Engineering, rough work during the construction process, or even cutting corners is not easy to check and find, resulting in loss of control of construction quality, affecting the quality and service life of the 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.

[0006]4) Wall external decoration materials, construction comprehensive cost are high, construction period is long, and thus bring negative effects in many aspects such as comprehensive benefits and environmental impact

[0007] So far, although the relevant departments have made great efforts in building materials and construction technology, and have continuously developed various new materials and technologies, the overall effect is not ideal.
