Description

Technical Field

[0001] The utility model relates to the technical field of composite thermal insulation boards, in particular to a vacuum thermal insulation composite thermal insulation board which is easy to install. Background Art

[0002] The vacuum insulation panel is composed of a filling core material and a vacuum protective surface layer. It can effectively avoid heat transfer caused by air convection, so that the thermal conductivity can be greatly reduced. When it is used in the construction field, it is usually necessary to wrap a hardened protective shell on the outside to prevent the vacuum insulation panel from being damaged and leaking and failing. The vacuum insulation panel is combined with the hardened protective shell to form a vacuum insulation composite insulation panel.

[0003] When installing a vacuum insulation composite insulation board on a building wall, usually a hole is drilled on the hardened protective shell first, and then the anchor bolts used for fixing are inserted into the hole for fixing; since the vacuum insulation board is close to the edge of the hardened protective shell, the vacuum insulation board is easily damaged during drilling, resulting in the failure of the insulation performance of the vacuum insulation composite insulation board. In addition, the installation of a vacuum insulation composite insulation board requires multiple anchor bolts for fixing, which not only has low installation efficiency, but also wastes installation materials. Therefore, a vacuum insulation composite insulation board that is easy to install is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a vacuum insulation composite thermal insulation board which is easy to install, so as to solve the problems existing in the prior art proposed in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A vacuum insulation composite thermal insulation panel that is easy to install comprises a vacuum insulation panel and a hardened protective shell. The vacuum insulation panel is evenly wrapped with the hardened protective shell on the outside. The hardened protective shell is provided with installation grooves at the four corners. The structural shape of the installation grooves is set to be a quarter arc.

[0007] Preferably, the vacuum insulation panel is made of a core material coated with a high-barrier film and vacuum-sealed, the core material is made of silica or glass fiber, the high-barrier film includes an outer layer film, a middle layer film and an inner layer film arranged in sequence from the outside to the inside, the outer layer film is made of nylon or PVC, the middle layer film is a composite of at least one of VMPET film, PVDC film, PVA film, PP film, and PVC film, and the inner layer film is made of PE material.

[0008] Preferably, the hardened protective shell is made by mixing flame-retardant expandable polystyrene foam particles, expanded perlite powder, hydraulic inorganic gelling material, high molecular polymer, additives and water.

[0009] Preferably, alkali-resistant glass fiber mesh is pressed onto both side end surfaces of the hardened protective shell.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model hardens the arc-shaped installation grooves at the corners of the protective shell to form installation holes after splicing multiple composite insulation boards. One anchor bolt can be used to fix the corners of multiple composite insulation boards. The composite insulation board eliminates the need for drilling during installation, reduces the risk of damage to the vacuum insulation board, improves installation efficiency, and saves installation materials.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] See also Figure 1-4 , the utility model provides the following technical solutions:

[0018] A vacuum insulation composite thermal insulation panel which is easy to install comprises a vacuum insulation panel 1 and a hardened protective shell 2. The vacuum insulation panel 1 is evenly wrapped with the hardened protective shell 2 on the outside. The vacuum insulation panel 1 is made of a core material coated with a high-barrier film and vacuum-sealed. The core material is made of silicon dioxide or glass fiber. The high-barrier film comprises an outer film, a middle film and an inner film which are arranged in sequence from the outside to the inside. The outer film is made of nylon or PVC. The middle film is a composite of at least one of VMPET film, PVDC film, PVA film, PP film and PVC film. The inner film is made of PE. The arrangement of the vacuum insulation panel 1 can ensure the thermal insulation performance of the composite thermal insulation panel.

[0019] The hardened protective shell 2 is made of a mixture of flame-retardant expandable polystyrene foam particles, expanded perlite powder, hydraulic inorganic gelling material, high molecular polymer, additives and water; by mixing the above raw materials and evenly coating the outside of the vacuum insulation panel 1, the vacuum insulation panel 1 can be effectively protected.

[0020] Alkali-resistant glass fiber mesh is pressed on both side end surfaces of the hardened protective shell 2; the provision of the alkali-resistant glass fiber mesh can improve the strength of the hardened protective shell 2, thereby improving its crack resistance and impact resistance.

[0021] The hardened protective shell 2 is provided with installation grooves 3 at the four corners. The structural shape of the installation grooves 3 is set to a quarter arc shape. By splicing and installing adjacent composite insulation boards, the spliced ​​installation grooves 3 can form a mounting hole. Anchor bolts 4 are inserted into the mounting hole for fixing. That is, one anchor bolt 4 can fix the corners of three composite insulation boards, which not only eliminates the step of drilling holes, but also saves installation materials.
