[0002] Vacuum heat insulation board is a new generation of high-performance insulation material rapidly developed in recent years, and the thermal conductivity of vacuum heat insulation board can be as low as 1 / 10 of traditional insulation materials. A thin piece of vacuum heat insulation board can provide the same insulation effect as 10 cm of traditional insulation materials. With the maturation of vacuum heat insulation board technology and the gradual reduction of costs, vacuum heat insulation board has been applied from high-end fields such as military and aerospace to commercial and civilian fields, showing excellent energy-saving and emission-reducing effects.

[0003] Vacuum heat insulation board is also widely used in the field of construction. Vacuum heat insulation board is mainly composed of barrier film, thermal insulation core material and gas adsorption material. The barrier film is the "sealed packaging bag" on the outer layer of the vacuum heat insulation board. However, due to the harsh use environment of the construction industry, the barrier film of conventional vacuum heat insulation board often breaks and leaks, causing insulation failure. SUMMARY

[0004] To solve the problems of the prior art, the present utility model combines the prior art and is based on practical application to provide a vacuum heat insulation composite board. The board has better performance indicators than simple vacuum heat insulation boards in the construction industry.

[0009] Further, the upper middle layer board and the lower middle layer board are homogeneous boards, inorganic composite polystyrene boards, or permeable boards.

[0010] Furthermore, the upper and lower middle layer boards are bonded to the upper and lower surfaces of the inner vacuum insulation board using adhesives.

[0011] Furthermore, the adhesive is a polyurethane adhesive or a polymer cement adhesive.

[0012] Furthermore, an alkali-resistant fiberglass mesh is placed in the polymer mortar.

[0013] Furthermore, the density of the alkali-resistant fiberglass mesh is not less than 80 g / m². 2 .

[0014] Furthermore, the thickness of the polymer mortar is not less than 0.5 mm.

[0015] Furthermore, the polymer mortar is a polymer crack-resistant mortar or a polymer interface mortar, and the polymer mortar wraps all six sides of the board formed by the combination of the upper and middle layer board, the inner vacuum insulation board, and the upper and middle layer board.

[0016] The beneficial effects of this utility model are:

[0017] 1. The composite panel structure of this utility model has a stronger insulation effect than traditional vacuum insulation panels and can reduce the breakage rate, which helps to maintain the overall insulation of buildings.

[0024] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] This embodiment provides a vacuum insulation composite panel. Its main structure is as follows: Figure 1 As shown.

[0026] The vacuum insulation composite panel in this embodiment mainly consists of an inner vacuum insulation panel 1, a middle panel 2, and polymer mortar 3.

[0027] The middle layer board 2 is divided into an upper middle layer board and a lower middle layer board. The upper middle layer board and the lower middle layer board are respectively attached to the upper and lower surfaces of the inner vacuum insulation board 1 by adhesive. The polymer mortar 3 covers the above-mentioned combined board in six directions.

[0028] In a preferred embodiment provided in this example, the lower middle layer and the upper middle layer are made of the same material, and have the following characteristics:

[0029] Board-shaped thermal insulation material, fire-retardant Class A material, density between 100 and 200 kg / m³ 3 The thickness of the material can be determined according to the actual working conditions.

[0030] The lower and upper middle layers can be made of homogeneous boards, inorganic composite polystyrene boards, or permeable boards, among others. Inorganic composite polystyrene boards are preferred. During the manufacturing process, high-end fire-resistant materials are used internally, giving the board excellent fire resistance. The production of inorganic composite polystyrene boards does not produce wastewater, exhaust gas, or harmful gas emissions, posing no health risks to workers. This environmentally friendly performance aligns with current societal requirements for energy-efficient and environmentally friendly buildings. The polystyrene foam core in inorganic composite polystyrene boards provides excellent thermal insulation properties, making them suitable for roofing, exterior wall, and floor insulation. Furthermore, inorganic composite polystyrene boards are highly malleable and easy to install. By bonding the inorganic composite polystyrene board to the upper and lower surfaces of the inner vacuum insulation board, damage to the vacuum insulation membrane is avoided, and the compressive strength and stability of the board are significantly improved.

[0031] The inorganic composite polystyrene board is connected to the inner vacuum insulation board with an adhesive, which can be polyurethane adhesive or polymer cement adhesive, making the composite board simple and convenient to manufacture.

[0032] Polymer mortar 3 is located on the outermost layer and is mainly used to wrap the board. Polymer mortar 3 can be either polymer crack-resistant mortar or polymer interface mortar. The thickness of polymer mortar 3 should not be less than 0.5mm, and alkali-resistant fiberglass mesh should be embedded within it, with a fiberglass mesh strength of not less than 120g / m². 2 .

[0033] The structural design of the polymer mortar 3 with embedded fiberglass mesh can improve the tensile strength and overall stability of the board, while giving the board excellent crack resistance, making the composite board perform better in building applications.
