Technical Field
[0001] The utility model relates to the field of heat insulation boards and belongs to a composite heat insulation board Background Art
[0002] In the transportation of goods, insulation boards are usually made of polystyrene resin as raw materials, other raw materials and polymers, which are heated and mixed while injecting catalysts, and then extruded and pressed to form rigid foam plastic boards with moisture-proof and waterproof properties. The current insulation boards have a single insulation function, and their corrosion resistance and friction resistance are poor, making it increasingly difficult to meet people's usage needs. The transportation of goods may be affected by environmental conditions, such as humidity, chemicals, salt water, friction between goods and insulation boards, etc. These factors may cause corrosion and damage to the protective board. Therefore, the protective board needs to have good corrosion resistance and wear resistance to ensure that it can maintain stable performance for a long time in various environments.

[0025] In order to improve the wear resistance and corrosion resistance of the insulation board and meet more transportation scenarios, the utility model provides the following technical solutions.
[0026] A composite heat-insulating board comprises, from top to bottom, a corrosion-resistant layer 1, a base layer 2, a protective layer 4, a metal heat-insulating layer 6, and a heat-insulating layer 7; the corrosion-resistant layer 1 is an inner layer in contact with goods, and the heat-insulating layer 7 is an outer layer in contact with the outside world.
[0027] In this embodiment, the metal insulation layer 6 and the foaming layer for heat preservation are connected by glue or adhesive agent. This connection method can ensure the close adhesion between the metal insulation layer 6 and the foaming layer, thereby effectively preventing the flow of air or heat and improving the heat insulation effect. During the manufacturing process, the adhesive agent will be evenly coated on the surface of the metal insulation layer 6 or the foaming layer, and then they will be pressed together. After a certain curing time, the adhesive agent will form a firm connection. The adhesive agents that can be selected include polyurethane glue, acrylic glue, double-sided tape, etc.
[0028] The heat-insulating layer 7 is a foaming material, the metal heat-insulating layer 6 is an aluminum foil, and the metal heat-insulating layer 6 is placed on the adhesive backing 3 to reflect and block the conduction of heat.
[0029] The protective layer 4 is a PVDF film. The PVDF film has weather resistance, chemical stability and excellent mechanical properties, and improves durability and anti-fouling ability. The PVDF film in this embodiment is a prior art and can be obtained commercially.
[0030] In one or more embodiments, the corrosion-resistant layer 1 is a fluorine film layer. The fluorine film layer is a transparent PVF film or PVDF film, which is a prior art and commercially available. The fluorine film layer has the functions of salt spray resistance, UV aging resistance, chemical corrosion resistance, etc., and has a protective effect on the substrate. In this embodiment, the fluorine film layer is tightly combined with the substrate layer 2 by hot pressing. The fluorine film layer and the PET film are pressed together at high temperature. During the hot pressing process, the surfaces of the two materials will be partially melted, and a firm connection will be formed after cooling. This is a prior art and will not be described in detail here.
[0031] In a preferred embodiment, the base layer 2 is a PET film. The PET film has good mechanical properties, chemical stability and heat resistance. In the composite material, the PET film provides support and stability as a base, and can also be used as a basis for other materials. In other embodiments, polypropylene film, polycarbonate film, polyethylene film and composite fiberboard can also be selected as the base, all of which can achieve the technical effect of the utility model, and are not limited here.
[0032] In this embodiment, the metal heat insulation layer 6 and the protective layer 4 are connected by an adhesive 5. In other embodiments, other cross-linking agents or adhesives may be used for connection, which can also achieve the technical effect of the utility model, and will not be described in detail here.
[0033] In this embodiment, the base layer 2 and the protective layer 4 are connected by the adhesive 3. In other embodiments, other cross-linking agents or adhesives may be used for connection, which can also achieve the technical effect of the utility model, and will not be described in detail here.
[0034] In a preferred embodiment, the thickness of the adhesive 5 is 4-10 μm.
[0035] In a preferred embodiment, the foaming material is 20 times XPE foaming material. XPE foaming material (cross-linked polyethylene foaming material) is an excellent insulating material with low density, good thermal insulation and compressive resistance. It is made of cross-linked polyethylene material. During the foaming process, gas is injected into the polyethylene to form a fine bubble structure, which makes the material light, soft and heat-insulating. Compared with ordinary foam materials, XPE foaming material has a higher density and a more delicate bubble structure, so it has better insulation and compressive resistance to a certain extent. Generally, the insulation performance of XPE foaming material can reach 20 times that of ordinary foaming material. XPE foaming material can be used in building insulation, automotive interior, sports equipment, thermal insulation packaging and other fields. During the transportation of goods, XPE foaming material can be used as part of the protective plate to provide additional thermal insulation and protection effects to ensure that the goods are not affected by external temperature changes during transportation.
[0036] In a preferred embodiment, the thickness of the corrosion-resistant layer 1 is 1-10 μm, for example, the thickness may be 1 μm, 2 μm, 5 μm, 8 μm, 10 μm, but not limited to the listed values, and other values not listed in the numerical range are also applicable.
[0037] In a preferred embodiment, the thickness of the base layer 2 is 0.1-0.25 mm. For example, the thickness can be 0.1 mm, 0.2 mm, 0.25 mm, but not limited to the listed values, and other values not listed in the numerical range are also applicable.
[0038] In a preferred embodiment, the thickness of the protective layer 4 is 20-35 μm. For example, the thickness may be 20 μm, 25 μm, or 35 μm, but is not limited to the listed values. Other values not listed within the numerical range are also applicable.
[0039] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
