Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation structures, in particular to a heat insulation board with a bendable sewn structure. Background Art

[0002] Current insulation panels are generally flat, manufactured by pressing raw materials under high pressure. Due to the limitations of existing finished insulation panels, the panels must be cut in pairs when creating insulation layers on the exterior walls of polygonal objects. To ensure a tighter fit between the panels and maintain effective insulation, the edges must be trimmed and then bonded with adhesive. Finally, the joints must be waterproofed and sealed, making the entire process cumbersome, inefficient, and difficult to install. Utility Model Content

[0003] To achieve the above-mentioned object, the utility model provides a bendable sewn insulation board, comprising an inorganic fiber bag, the interior of which is divided into a plurality of filling spaces by a plurality of sewing lines, and the inorganic fiber bag is covered with a connecting piece on the outside of the area where the sewing lines are located;

[0004] A plurality of heat-insulating units are respectively installed in all the filling spaces. The heat-insulating units are filled with powder heat-insulating material and installed in all the filling spaces and are obtained by hydraulic molding.

[0005] In some possible implementations, the connecting sheet is filled with powdered thermal insulation material.

[0006] In some possible implementations, the powder thermal insulation material is formed by high-speed mixing of inorganic non-metallic oxides, inorganic additives, and inorganic fibers.

[0007] In some possible implementations, a feed filling port is provided on one end of the inorganic fiber bag, and the feed filling port is sewn with sewing thread.

[0008] In some possible implementations, the sewing thread is one or two of polyamide thread, polytetrafluoroethylene thread, aramid thread, high silica fiber thread, quartz fiber thread, alumina fiber thread, organic fiber thread and inorganic fiber thread.

[0009] In some possible implementations, the sewing thread has a diameter of 0.1 to 1 mm.

[0010] In some possible implementations, the inorganic fiber bag is coated with a waterproof layer.

[0011] In some possible implementations, a plurality of metal wires are inserted into the inorganic fiber bag.

[0012] In some possible implementations, a metal mesh bag is provided inside the inorganic fiber bag, and the insulation unit is located inside the metal mesh bag.

[0013] Compared to existing technologies, the present invention offers the following advantages: The present invention's sewn, bendable insulation panels utilize inorganic fiber bags to hold powdered insulation material, which is then hydraulically formed using hydraulic equipment. This design ensures that the powdered insulation material fits perfectly with the inorganic fiber bags during hydraulic forming, ensuring that the resulting insulation unit will not separate from the bags, ensuring optimal performance. Furthermore, connecting tabs are provided on both sides of the area between each filler space, effectively providing secondary coverage for that area, ensuring the insulation's effectiveness and preventing a lack of powdered insulation material that would otherwise reduce the insulation's effectiveness.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] Reference Figures 1 to 3 The illustrated embodiment shows a bendable insulation board with a sewn structure, comprising an inorganic fiber bag 10 and a plurality of insulation units 20. The interior of the inorganic fiber bag 10 is divided into a plurality of filling spaces 11 by a plurality of sewing lines 13. The outer side of the inorganic fiber bag 10 in the area where the sewing lines 13 are located is covered with a connecting piece 12. One end of the connecting piece 12 is bonded and fixed to the outer surface of the inorganic fiber bag 10, and the other end is a free end to ensure that the insulation board can bend at the sewing line 13, or the two ends of the connecting piece 12 form sheet ears, and the sheet ears are partially bonded and fixed to the outer surface of the inorganic fiber bag 10. At this time, although the connecting piece 12 covers the sewing line 13, there is still a certain space for movement relative to the inorganic fiber bag 10, which does not affect the bending of the insulation board at this location; a plurality of insulation units 20 are respectively installed in all the filling spaces 11. The insulation units 20 are filled and installed in all the filling spaces 11 with powder insulation material and are obtained by hydraulic molding.

[0022] It should be noted that in the above-described embodiment, the inorganic fiber bag 10 can be made of conventional carbon fiber, glass fiber, or boron fiber. However, after being filled with the powdered insulation material and compacted using hydraulic equipment, the inorganic fiber bag 10 must possess sufficient compressive and tensile strength. Furthermore, the area where the sewing line 13 is located can serve as the bending line between two adjacent insulation units 20, facilitating the insulation covering of regular surfaces.

[0023] This sewn, bendable insulation panel utilizes inorganic fiber bags 10 to enclose powdered insulation material, which is then hydraulically formed using hydraulic equipment. This design ensures that the powdered insulation material adheres perfectly to the inorganic fiber bags 10 during hydraulic forming, ensuring that the resulting insulation units 20 will not separate from the inorganic fiber bags 10, thus ensuring optimal performance. Furthermore, connecting tabs 12 are provided on both sides of the area between each filler space 11. This design effectively provides secondary coverage for this area, ensuring thermal insulation and preventing a reduction in thermal insulation due to a lack of powdered insulation material.

[0024] In some possible implementations, in order to increase the thermal insulation capacity of the connecting piece 12, the connecting piece 12 is filled with powdered thermal insulation material. The powdered thermal insulation material in the connecting piece 12 needs to be compacted to ensure flatness. In some embodiments, it can even be hydraulically pressed by adding inorganic adhesives to increase its softness.

[0025] In the above embodiment, to ensure thermal insulation, the powder insulation material is formed by high-speed mixing of inorganic non-metallic oxides, inorganic additives, and inorganic fibers. The inorganic non-metallic oxides may be silicon oxide, magnesium oxide, aluminum oxide, etc., while the inorganic additives may be adhesives or flame-retardant insulation materials such as aluminum hydroxide or aluminum silicate. The inorganic fibers may be conventional glass fibers, asbestos fibers, carbon fibers, etc.

[0026] In some possible implementations, to facilitate filling with powdered insulation material, a feed opening is provided at one end of the inorganic fiber bag 10, which is sewn shut with sewing thread 13. The sewing effect here is essentially the same as that of the filler space 11, and therefore will not be described in detail in this application. It should be noted that in this application, the spacing between the sewing threads 13, whether sewing the feed opening or the filler space 11, is 3-8 mm.

[0027] In the above-mentioned improvement, to improve the later use effect and ensure sufficient tensile strength, the sewing thread 13 is one or two of polyamide thread, polytetrafluoroethylene thread, aramid thread, high silica fiber thread, quartz fiber thread, alumina fiber thread, organic fiber thread, and inorganic fiber thread. The diameter of the sewing thread 13 is 0.1 to 1 mm.

[0028] See also Figure 3 In some improved embodiments, in order to improve the waterproof ability of the entire insulation board, the inorganic fiber bag 10 is coated with a waterproof layer 14.

[0029] In some possible implementations, to ensure that the inorganic fiber bag 10 has sufficient toughness after the powder insulation material is loaded into the filling space 11 and hydraulically pressurized to prevent cracking, in one embodiment of the present application, a plurality of metal wires are inserted into the inorganic fiber bag 10 to enhance the toughness and strength of the inorganic fiber bag 10. In some improved embodiments, a metal mesh bag 15 is provided within the inorganic fiber bag 10, and the insulation unit 20 is located within the metal mesh bag 15. In fact, the metal mesh bag 15 can be woven during the weaving process of the inorganic fiber bag 10, so that the metal mesh bag 15 can adapt to the corresponding inorganic fiber bag 10 and reduce the gap between the two.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
