Description

Technical Field

[0001] This utility model relates to building insulation, and more particularly to a multi-layer composite insulation material. Background Technology

[0002] PVC, when foamed with other aggregates, provides excellent thermal insulation, commonly used in wall insulation boards. However, a current technical challenge is that these boards are prone to deformation when subjected to thermal expansion and contraction, leading to separation from the wall. Specifically, when the temperatures on both sides of the board differ, the warmer side expands more significantly, causing the board to bend under stress and creating internal stress. This is especially problematic in winter, when the side against the wall is warmer than the side closer to the wall, resulting in greater contraction on the outer side. This causes the board to bend outwards, forming curled edges and separating from the wall at the corners. In severe cases, the insufficient bonding area between the board and the wall can cause the board to fall off, posing a safety hazard. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] To address the problems mentioned above, this utility model provides the following technical solution:

[0005] A multi-layer composite thermal insulation material, for which:

[0006] It has an adhesive side and an outer side, the adhesive side being used to adhere to the building;

[0007] It includes at least an insulation layer, and a compression zone is formed on the side of the insulation layer near the bonding side, and the insulation layer matrix flows into the compression zone during the expansion process.

[0008] As a preferred technical solution for a multi-layer composite thermal insulation material, a collapse angle is formed inside the extrusion zone, and the collapse angle has an outward extending structure.

[0009] As a preferred technical solution for a multi-layer composite thermal insulation material, it also includes a tensile layer, which has a woven structure and is embedded on one side close to the bonding side.

[0010] As a preferred technical solution for a multi-layer composite thermal insulation material, the tensile layer and the extrusion zone are located at the same position along the thickness direction of the thermal insulation layer.

[0011] As a preferred technical solution for a multi-layer composite thermal insulation material, the tensile layer is woven from fibers or metals.

[0012] As a preferred technical solution for a multi-layer composite thermal insulation material, it also includes an adhesive layer disposed on the adhesive side, the adhesive layer being connected to the building body in conjunction with an adhesive, and the tensile layer having a first extension end connected to the adhesive layer.

[0013] As a preferred technical solution for a multi-layer composite thermal insulation material, it also includes a waterproof layer, which is disposed on the outer side, and the tensile layer is provided with a second extension end and connected to the waterproof layer.

[0014] The beneficial effects of the multi-layer composite thermal insulation material provided by this utility model are as follows: through the structure of the extrusion zone, when the material is placed on the wall, if the expansion effect on the side closer to the wall is greater than that on the outside, the expanded volume can be squeezed into the extrusion zone. That is, the extrusion zone accommodates the excess volume, thereby reducing the difference in volume change on both sides of the material, thus reducing the occurrence of overall material deformation, that is, reducing the separation of the material from the building body due to stress, and thus making it better used on the exterior of the building.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Reference Figure 1-3 The present invention provides a multi-layer composite thermal insulation material. For ease of description, it is referred to as... Figure 2 For reference, the side of the material facing upwards is the bonding side, and the side facing downwards is the outer side. In actual application, the bonding side is also the side used to bond to the wall. Specifically, the material includes insulation layer 1 (PVC foam layer), bonding layer 2 and waterproof layer 3 bonded to insulation layer 1, which are located on the bonding side and the side closer to the outer side, respectively.

[0027] The bonding layer 2 (which can be made of polyester fiber cloth or natural fiber cloth) is mainly used to better connect the adhesive to the wall. The insulation layer 1 also has a compression zone 4 inside. The compression zone 4 is porous and evenly distributed along the area direction of the insulation layer 1. The compression zone 4 is located on the side of the insulation layer 1 closer to the bonding side. Through the structure of the compression zone 4, when there is a temperature difference between the two sides of the insulation layer 1, that is, when the temperature of the bonding side is higher than that of the outside, the material on the insulation layer 1 closer to the bonding side expands more than that on the outside. This allows the excess volume of the material on that side to fill the compression zone 4, thereby reducing the degree of expansion of the entire surface close to the bonding side. In other words, it reduces the expansion difference between the two sides of the insulation layer 1 caused by the temperature difference between the side closer to the wall and the outside during actual application, thereby reducing the occurrence of overall material warping.

[0028] The above, such as Figure 2 As shown in the view, the compression zone 4 is an inverted teardrop shape, which creates a collapse angle 5 on its inner wall. When the material expands, the collapse angle 5 is squeezed, making the compression zone 4 easier to compress. That is, the collapse angle 5 guides the material to expand into the compression zone 4, making it less likely for the material to be squeezed to other places when it expands, thus preventing uneven local deformation of the material, such as bulging.

[0029] Furthermore, based on the above, a tensile layer 6 is also provided within the insulation layer 1. The tensile layer 6 has a woven mesh structure and is embedded within the material of the insulation layer 1. In the thickness direction of the insulation layer 1, the tensile layer 6 and the extrusion zone 4 are located at the same position. Due to the extrusion zone 4, the tensile layer 6 can maintain the tensile strength of the insulation layer 1 near the bonding side. The tensile layer 6 can be woven from metal wire, high molecular weight polyethylene fiber, or nylon wire to provide sufficient tensile strength. At the same time, the tensile layer 6 further limits the expansion effect of the insulation layer 1 near the bonding side, which also prevents the material from warping. The waterproof layer 3 (a membrane structure) further improves the overall waterproof effect of the material to prevent moisture from penetrating the tensile layer 6 and causing corrosion, thus protecting the tensile layer 6.

[0030] In order to ensure the firmness of the bond between the multi-layer structure, the tensile layer 6 is provided with a first extension end 7 and a second extension end 8 on both sides, which are respectively connected to the bonding layer 2 and the waterproof layer 3, thereby tightening the two towards the middle to ensure the overall bonding strength.

[0031] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
