Description

Technical field:

[0001] The utility model relates to a wood-grain imitation double-decoration panel with good thermal insulation performance. Background technology:

[0002] Double veneer generally refers to melamine board. Its base material is particle board, medium-density fiberboard, plywood, etc. It is made of base material and surface bonding and is a commonly used wood material.

[0003] With the advancement of architectural decoration technology, thermal insulation double veneer panels are gradually widely used in the field of construction. However, the existing thermal insulation double veneer panels mostly use a single structure of thermal insulation layer inside, such as only using thermal insulation board for thermal insulation. In this single thermal insulation structure, the thermal insulation effect is not ideal. Therefore, it is urgent to develop a double veneer panel with good thermal insulation to meet the use needs. Utility model content:

[0004] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide an imitation wood grain double veneer panel with good thermal insulation performance.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a wood-grain imitation double-decorated panel with good thermal insulation, comprising a plywood core, an upper wood-grain imitation finishing layer and a lower wood-grain imitation finishing layer respectively arranged on the upper and lower sides of the plywood core, an insulation layer is arranged between the plywood core and the upper wood-grain imitation finishing layer, and between the plywood core and the lower wood-grain imitation finishing layer, the insulation layer comprises a pair of extruded polystyrene boards distributed up and down, and EPS insulation particles are arranged between the pair of extruded polystyrene boards.

[0006] Furthermore, a wooden board is sandwiched between a pair of extruded polystyrene boards, the wooden board is provided with polygonal honeycomb holes, and the honeycomb holes are filled with EPS thermal insulation particles.

[0007] Furthermore, the upper imitation wood facing layer and the extruded polystyrene board, the extruded polystyrene board and the wooden board, the extruded polystyrene board and the plywood core, and the lower imitation wood facing layer and the extruded polystyrene board are all bonded with petroleum resin water-based adhesive.

[0008] Furthermore, the plywood core is formed by hot pressing after a plurality of veneers and a plurality of layers of metal woven mesh are alternately laid in layers.

[0009] Compared with the prior art, the utility model has the following effects: the utility model has a reasonable structural design, by arranging insulation layers on the upper and lower sides of the plywood core, and the insulation layer adopts two extruded polystyrene boards to sandwich EPS insulation particles, and uses EPS insulation particles to achieve good insulation effect. At the same time, the two extruded polystyrene boards are combined to further improve the insulation effect, so that the imitation wood grain double veneer panel has good thermal insulation properties. Description of the drawings:

[0010] Figure 1 It is a schematic diagram of the main cross-sectional structure of an embodiment of the utility model;

[0011] Figure 2 It is a top view structural schematic diagram of a wooden board in an embodiment of the utility model. Specific implementation method:

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0013] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply 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 invention.

[0014] like Figure 1 As shown, the utility model is a wood-grain imitation double veneer panel with good thermal insulation, comprising a plywood core 1, an upper wood-grain imitation finishing layer 2 and a lower wood-grain imitation finishing layer 3 respectively arranged in parallel on the upper and lower sides of the plywood core 1, and a thermal insulation layer 4 is arranged between the plywood core 1 and the upper wood-grain imitation finishing layer 2, and between the plywood core 1 and the lower wood-grain imitation finishing layer 3, that is, the upper and lower sides of the plywood core are insulated by the thermal insulation layer; specifically, the thermal insulation layer 4 comprises a pair of extruded polystyrene boards 5 distributed up and down, and EPS thermal insulation particles 6 are arranged between the pair of extruded polystyrene boards 5. By arranging thermal insulation layers on both the upper and lower sides of the plywood core, and the thermal insulation layer adopts two extruded polystyrene boards to sandwich the EPS thermal insulation particles, the EPS thermal insulation particles are used to achieve a good thermal insulation effect, and the thermal insulation effect is further improved by combining the upper two extruded polystyrene boards, so that the wood-grain imitation double veneer panel has good thermal insulation.

[0015] Extruded polystyrene board is a rigid foam plastic board made of polystyrene resin supplemented with polymers, which is heated and mixed, injected with catalyst, and then extruded to form continuous closed-cell foam. Its interior is an independent closed-cell structure. It is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging, and low thermal conductivity. The thermal insulation effect can be further improved by combining two extruded polystyrene boards.

[0016] In another embodiment, a pair of extruded polystyrene boards 5 are sandwiched with a wooden board 7, the wooden board 7 is provided with polygonal honeycomb holes 8, the honeycomb holes 8 are filled with EPS thermal insulation particles 6, and the EPS thermal insulation particles are used to achieve a good thermal insulation effect. Furthermore, the EPS thermal insulation particles are pressurized and compacted in the honeycomb holes.

[0017] In another embodiment, the upper imitation wood veneer layer 2 and the extruded polystyrene board 5, the extruded polystyrene board 5 and the wooden board 7, the extruded polystyrene board 5 and the plywood core 1, and the lower imitation wood veneer layer and the extruded polystyrene board 5 are all bonded with petroleum resin water-based adhesive. The petroleum resin water-based adhesive does not release formaldehyde and does not cause pollution, thereby effectively improving the overall environmental protection.

[0018] In another embodiment, the plywood core 1 is formed by hot pressing after a plurality of veneers and a plurality of metal woven meshes are alternately laid in layers. The metal woven meshes can enhance the tensile strength and deformation resistance of the board, thereby reducing the overall thickness of the plywood core.

[0019] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0020] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0021] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated forming process.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
