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, while the paint finish is prone to fading, cracking, water seepage, etc.
[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] 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

[0043] In step 3), the drying temperature of the wet body of the thermal insulation board is 190° C., and the drying time is 3.5 hours;

[0044] The metal plate in step 4) adopts titanium gold thin plate;

[0045] In step 5), the drying temperature of the thermal insulation and decorative composite board is ...

Embodiment 3

[0048] The preparation method of the inorganic cotton metal facing integrated exterior wall thermal insulation decorative board in this example is basically the same as that in Example 1, the difference is that:

[0049] The weight ratio of each component raw material in step 1) is: 8 parts of aluminum sulfate, 6 parts of aluminum phosphate and 3 parts of calcium stearate, the weight ratio that adds water during mixing is three kinds of raw material total amounts: water=1: 3 , the heating temperature is 100°C;

[0050] Step 2) The volume ratio of inorganic cotton and inorganic salt composite cementing slurry is: inorganic cotton: inorganic salt composite cementing slurry=8:1;

[0051] In step 3), the drying temperature of the wet body of the thermal insulation board is 180° C., and the drying time is 4 hours;

[0052] The metal plate in step 4) adopts titanium alloy thin plate;

[0053] In step 5), the drying temperature of the thermal insulation and decorative composite boa...

Abstract

The invention relates to an integrative external wall heat insulating decorative board for inorganic cotton metal finish and a preparation method thereof, wherein the heat insulating decorative board comprises a heat insulating layer and a finish layer, the heat insulating layer is molded by carrying out hybrid pressing on the inorganic cotton and inorganic salt composite cementing materials, the finish layer is a sheet metal, the heat retaining layer and the finish layer are pressed and molded integrally by an adhesive. The heat insulating layer of the heat insulating decorative board is made of a natural inorganic cotton material, thereby having excellent properties of non-toxicity, insipidity, corrosion resistance, incombustibility, acid and alkali resistance, heat insulation and preservation. At the same time, the metal finish has good flame retardant, waterproof and anti-cracking functions, the wall and the heat insulating layer are protected optimally, and the visual effects of high grade and luxury, decoration and environment beautification 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 thermal insulation decorative panel integrated with inorganic cotton and metal facing 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 anti-compression 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 comply with green environmental protection, non-toxic and harmless At the same time, the development of social economy ...
