Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of foam glass thermal insulation boards, in particular to a foam glass core material thermal insulation decorative board. 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. During the production process, the foam glass panels need to be cut and split. As a whole, the foam glass has a closed-cell structure inside, and the overall tensile and compressive strengths are high. However, due to the splitting and cutting, the hole walls are damaged in the cross section, resulting in lower strength, easy to fall off powder and slag, which is not conducive to the compounding of thermal insulation decorative panels. In addition, the two-component polyurethane composite glue commonly used in integrated panels has a certain volume shrinkage during the curing process, and the decorative panels and foam glass of the decorative panels have different expansion coefficients. The foam glass itself is brittle, and there is a risk of shrinkage by the glue and stress caused by the expansion and contraction of the decorative panels to damage the surface structure; the bonding surface is prone to delamination during transportation, cutting and impact. Summary of the invention
[0003] The utility model aims to provide a foam glass core thermal insulation decorative board, which is intended to solve and improve the problem that the hole wall of the foam glass is damaged after cutting, resulting in low strength, easy powder and slag falling, which is not conducive to the composite of the thermal insulation decorative board and easy delamination of the bonding surface.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:
[0005] A foam glass core thermal insulation decorative board comprises a decorative panel, a first adhesive layer, a foam glass core, a second adhesive layer and a backing layer stacked in sequence from top to bottom; a first reinforcement layer is arranged between the first adhesive layer and the foam glass core material; a second reinforcement layer is arranged between the foam glass core material and the second adhesive layer.
[0006] On the basis of the above solution and as a preferred solution of the above solution: the first reinforcement layer and the second reinforcement layer are attached to the surface of the foam glass core material by spraying.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the foam glass core material is composed of a plurality of foam glass pieces spliced together.
[0008] 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.
[0009] 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.
[0010] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: the foam glass core material is sprayed on its surface to form the first and second reinforcement layers before the veneer and backing are compounded, and the first and second reinforcement layers are used to fix and reinforce the broken pore walls on the surface of the foam glass core material, thereby increasing the strength of its surface. After compounding with the backing and veneer, it will have good adhesion, avoid stratification, and ensure the composite quality. Moreover, the reinforcement and filling of the foam glass surface by the first and second reinforcement layers is equivalent to adding a buffer layer between the veneer, backing and foam glass core material. In the event of deformation or external impact, a part of the stress is absorbed, thereby better protecting the foam glass and avoiding local damage and stratification. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a schematic diagram of the structure of foam glass core material. DETAILED DESCRIPTION
[0013] 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.
[0014] 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.
[0015] 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.
[0016] See Figure 1-2As shown, the present application discloses a foam glass core 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; in actual production, the foam glass board needs to be cut and divided, and the foam glass as a whole has a closed-cell structure inside, and the overall tensile and compressive strengths are high, but due to the slitting and cutting, the hole wall is destroyed in the cross section, resulting in a decrease in strength, easy to fall off powder and slag, which is not conducive to the composite of the thermal insulation decorative board. In addition, the two-component polyurethane composite glue commonly used in the integrated board has a certain volume shrinkage during the curing process, and the foam glass itself is brittle, and there is a risk of the surface structure being destroyed by the shrinkage stress of the glue; the bonding surface is easy to delaminate under transportation, cutting and impact. For this reason, the present embodiment preferably has a first reinforcement layer 6 between the first adhesive layer 2 and the foam glass core material 3; and a second reinforcement layer 7 between the foam glass core material 3 and the second adhesive layer 4. Specifically, the first reinforcement layer 6 and the second reinforcement layer 7 are obtained by spraying the weather-resistant emulsion so that the weather-resistant emulsion adheres to the surface of the foam glass core material 3 and solidifies. The weather-resistant emulsion may be silicone-acrylic emulsion, acrylic emulsion, etc., so that the first reinforcement layer and the second reinforcement layer can fix and reinforce the broken pore walls on the surface of the foam glass core material, thereby increasing the strength of its surface. Then, after being compounded with the backing and the decorative panel, it will have good adhesion, avoid stratification, and ensure the composite quality. And the reinforcement and filling of the foam glass surface by the first reinforcement layer and the second reinforcement layer is equivalent to adding a buffer layer between the decorative panel, the back panel and the foam glass core material. Then, in the event of deformation or external impact, part of the stress is absorbed, thereby better protecting the foam glass and avoiding local damage and stratification.
[0017] In addition, it is further preferred that the foam glass core material 3 is composed of a plurality of foam glasses 31 spliced together. And it is preferred that there is a third adhesive layer 32 between adjacent foam glasses 31. Specifically, a large foam glass board can be cut and divided into a plurality of small foam glass blocks according to a set size, and then an adhesive is applied to the surface of the foam glass blocks 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. It is further preferred that the first adhesive layer 2, the second adhesive layer 4 and the third adhesive layer 32 all use a flexible adhesive. Of course, the above-mentioned flexible adhesive has good weather resistance, such as using a two-component polyurethane composite glue. Of course, it is also possible to stack multiple large foam glass boards in a multi-layer adhesive 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. Thus, the foam glass core material is formed by splicing multiple small pieces of foam glass, which is equivalent to having deformation gaps between each small piece of foam glass. After the composite veneer and backing are subjected to thermal expansion and contraction, the existence of the deformation gap can well compensate for the gaps generated by the veneer. The third bonding 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 foam glass core material as a whole. This further improves and avoids the problem of delamination between the veneer and the foam glass core material.
[0018] 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.
