Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation decorative plates, in particular to a foam glass thermal insulation decorative plate. Background Art

[0002] As an important exterior wall packaging and decoration material, thermal insulation decorative panels are now widely used in the construction industry. The traditional production method is to directly compound foam glass and decorative panels, but the materials of decorative panels are often aluminum-plastic panels, aluminum panels, etc. Since the linear expansion coefficient of foam glass is extremely low, and the expansion coefficient of decorative panels is quite different from that of foam glass panels, foam glass thermal insulation decorative panels are prone to thermal expansion and contraction, resulting in a large difference in thermal expansion and contraction between decorative panels and foam glass, thereby generating greater stress, leading to delamination of decorative panels and foam glass, and even foam glass fracture, and the larger the area of ​​a single board, the greater the risk of delamination. Summary of the invention

[0003] The utility model aims to provide a foam glass thermal insulation decorative board, which is intended to solve the problem of delamination and fracture of the decorative board and the foam glass board of the foam glass thermal insulation decorative board due to different thermal expansion coefficients.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] A foam glass thermal insulation decorative board comprises a decorative board, a first adhesive layer, a foam glass core material, a second adhesive layer and a backing layer which are stacked in sequence from top to bottom; the foam glass core material is composed of a plurality of foam glass pieces spliced ​​together.

[0006] On the basis of the above solution and as a preferred solution of the above solution: a third adhesive layer is provided between adjacent foam glasses.

[0007] On the basis of the above solution and as a preferred solution of the above solution: the first adhesive layer, the second adhesive layer and the third adhesive layer are all made of flexible adhesive.

[0008] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: a foam glass core material is formed by splicing a plurality of small pieces of foam glass, which is equivalent to having a deformation gap between each small piece of foam glass. Then, after the composite decorative panel and the backing are subjected to thermal expansion and contraction, the existence of the deformation gap can well compensate for the gap generated by the decorative panel. The third adhesive layer is flexible, so it can maintain the bonding of adjacent foam glasses while being able to be stretched and compressed to a certain extent, thereby ensuring the reliable connection and stability of the overall foam glass core material.

[0011] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0012] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0013] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0014] See Figure 1-2 As shown, the present application discloses a foam glass thermal insulation decorative board, including a decorative panel 1, a first adhesive layer 2, a foam glass core material 3, a second adhesive layer 4 and a backing layer 5 stacked in sequence from top to bottom; considering that the linear expansion coefficient of foam glass is extremely low, and the expansion coefficient of the decorative panel is greatly different from that of the foam glass board, this makes it easy for the foam glass thermal insulation decorative board to cause a large difference in the thermal expansion and contraction of the decorative panel and the foam glass due to thermal expansion and contraction, thereby generating a large stress, resulting in delamination of the decorative panel and the foam glass, and even the foam glass breaking; in this embodiment, the foam glass core material 3 is preferably composed of a plurality of foam glass 31. Specifically, a large foam glass board can be cut and divided into several small foam glass blocks according to a set size, and then an adhesive is applied on the surface of the foam glass block to be bonded, and then the adjacent foam glass blocks are squeezed tightly to form a third adhesive layer 32 between adjacent foam glasses 31, and the adjacent foam glasses are bonded by the third adhesive layer 32 to form an integral structure, which is then compounded with the backing and the decorative panel. Further preferably, the first adhesive layer 2, the second adhesive layer 4 and the third adhesive layer 32 are all made of flexible adhesive. Of course, the above-mentioned flexible adhesive has good weather resistance, such as using a two-component polyurethane composite adhesive. Of course, it is also possible to stack multiple large foam glass plates in multiple layers to a set height, and then use a cutting device to cut them according to a set thickness to form a foam glass core material 3.

[0015] The foam glass core material is made by splicing multiple small pieces of foam glass, which is equivalent to having deformation gaps between each small piece of foam glass. Then, after the composite decorative panel and backing are subjected to thermal expansion and contraction, the existence of the deformation gap can well compensate for the gap caused by the decorative panel. The third bonding layer is flexible, so it can keep the adjacent foam glasses bonded while being stretched and compressed to a certain extent, thereby ensuring the reliable connection and stability of the overall foam glass core material.

[0016] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
