[0002] During the building insulation process, insulation boards are needed to perform wall insulation operations to prevent the heat inside the building from escaping through the walls. At present, most building thermal insulation technologies use single materials or simple composite structures, such as rock wool, polystyrene foam or extruded boards. Although these materials have certain heat insulation properties, they still have significant defects: the thermal conductivity of these traditional insulation materials is generally above 0.03 - 0.04 W / (m·K), and the heat insulation efficiency is limited; module splicing relies on adhesives or bolts for fixation, and heat bridges are easily formed at the joints, resulting in heat loss, and the indoor temperature fluctuates significantly when the day-night temperature difference is large; in addition, in the prior art, the functions of the insulation layer and the structure layer are separated, and it is difficult to balance lightweight, high strength and construction convenience. For example, the roof insulation system needs additional reinforcement to withstand the trampling load, and it is not convenient to directly install the wall insulation system on the roof, and the existing solutions are difficult to meet the requirements of multiple scenarios.

Detailed implementation mode

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-9 , the present invention provides a technical solution: an integrated structure for building body thermal insulation, including a plurality of spliced module units. Each module unit includes a reflective layer 1, a thermal insulation composite layer 2, a corrugated aluminum plate 3 and a honeycomb aluminum plate 4 from outside to inside in sequence. A connecting piece 5 is fixedly arranged on the surface of the honeycomb aluminum plate 4, and the connecting piece 5 is used for installing and fixing with the wall or roof structure. When installing on the wall, the connecting piece 5 is directly connected to the building keel by screws; when installing on the roof, the connecting piece 5 is fixed by expansion bolts, and a waterproof coating is sprayed at the expansion bolts.

[0019] Mortise and tenon structures 6 are provided at the left and right side edges of the reflective layer 1. Longitudinal diversion grooves 7 are opened on the surface of the reflective layer 1 along the positions of the mortise and tenon structures 6. The mortise and tenon structure 6 includes a first connecting part 61 and a second connecting part 62. The first connecting part 61 is arranged on one side of the reflective layer 1 and includes a connecting groove 611. A semi-circular protrusion 612 is arranged on one side wall of the connecting groove 611, and a rectangular limiting groove 613 is arranged on the other side wall of the connecting groove 611. The length direction of the limiting groove 613 is parallel to that of the protrusion 612, the length direction of the protrusion 612 is parallel to that of the diversion groove 7, and the fixing surface of the protrusion 612 is parallel to the surface of the reflective layer 1. The plane where the limiting groove 613 is located is perpendicular to the surface of the reflective layer 1; The second connecting part 62 is arranged on the other side of the reflective layer 1 and includes a connecting piece 621. An installation groove 622 adapted to the protrusion 612 is arranged on one side of the connecting piece 621, and a semi-circular limiting block 623 adapted to the rectangular limiting groove 613 is arranged on the other side; When connected, the semicircular limit block 623 of the second connection part 62 on one module unit is embedded in the rectangular limit groove 613 of the first connection part 61 on the other module unit, and an angle of 130-150 degrees is formed between the surfaces of the reflective layer 1 of the two module units. Then, the unfixed module unit is pushed, and after the two modules are rotated to the same plane, the protrusion 612 is inserted into the installation groove 622 to limit the lateral displacement. The semicircular limit block 623 and the rectangular limit groove 613 limit the displacement perpendicular to the reflective layer 1.

[0020] When adjacent modules are spliced, the two guide grooves 7 form a continuous channel, and the channel connection is filled with sealant 8, which is expanded graphite glue or silicone sealant. The continuous channel formed by the guide groove 7 improves the drainage effect when it rains, especially when used on the roof.

[0021] The upper and lower sides of the reflective layer 1 are respectively provided with a convex groove 9 and a concave groove 10. When adjacent modules are spliced, the convex groove 9 is embedded in the concave groove 10. After the mortise and tenon structure 6 is connected, the convex groove 9 of the upper module is engaged with the concave groove 10 of the lower module along the length direction of the mortise and tenon structure 6, that is, through vertical movement, to complete the module unit connection.

[0022] The outer side of the thermal insulation composite layer 2 is covered with a rectangular connecting frame 11, and an annular groove 12 is opened on the surface of the rectangular connecting frame 11. The two sides of the rectangular connecting frame 11 are fixedly connected to the reflective layer 1 and the corrugated aluminum plate 3 respectively, and can be fixed by bolts or bonding. The rectangular connecting frame 11 is made of aluminum alloy with a thickness of 2-3mm. The annular groove 12 has a depth of 5mm and a width of 10mm. The rectangular connecting frame 11 covers the thermal insulation composite layer 2 to prevent damage during transportation and installation. At the same time, the trampling load is transmitted to the corrugated aluminum plate 3 through the rectangular connecting frame 11 to avoid local compression failure of the thermal insulation composite layer 2.

The surface layer is arranged on the side close to the reflective layer 1, with a pore size of 10 - 50 μm. The dense pores can significantly limit the mean free path of air molecules and reduce heat transfer by gas convection. The pore size of the intermediate layer is 50 - 300 μm, and the pore size of the bottom layer is 300 - 500 μm. The large pores can accommodate more phase change materials and increase the energy storage density. The aerogel matrix is produced by the sol-gel method combined with the template method, and pore grading is achieved by adjusting the precursor concentration and drying gradient, which will not be elaborated here. The paraffin-based phase change material is filled into the pores of the aerogel by vacuum impregnation, and the phase change temperature of the paraffin-based phase change material is 25 - 30 °C.

[0026] The reflective layer 1 includes a support layer 101 and a composite ceramic functional layer 102. The support layer 101 is a glass fiber board with a thickness of 3 - 5 mm. The support layer 101 is integrally formed with the mortise and tenon structure 6, the convex groove 9, and the concave groove 10. The composition of the composite ceramic functional layer 102 by mass percentage is: TiO2 60 - 80%, SiO2 20 - 40%. It is prepared by spraying with the sol-gel method and has a thickness of 0.3 - 0.5 mm, and the solar reflectivity ≥ 95%.

[0027] When preparing the composite ceramic functional layer 102, tetrabutyl titanate and tetraethyl orthosilicate are mixed in a molar ratio of 6:4, anhydrous ethanol and nitric acid are added as catalysts, and stirred to form a sol. Then, using a high-pressure airless spraying device, the sol is evenly sprayed onto the surface of the mechanical support layer 101, with a spraying thickness of 0.3 - 0.55 mm. Finally, it is sintered at 450 - 500 °C for 2 hours to form a dense TiO2 - SiO2 composite ceramic layer.

[0028] The surface of the reflective layer 1 is provided with anti-slip micro-protrusions 15. The height of the anti-slip micro-protrusions 16 is 1 - 3 mm, and the spacing is 3 - 10 cm. When used on the roof, the set anti-slip micro-protrusions play an anti-slip effect.
