In order to meet the diverse functional requirements, the current composite panel structure is becoming more and more complex, and it is impossible to achieve the effect of both multifunctionality and lightweight. Utility Model Content

[0003] In view of the problems faced by composite panels in practical applications, the purpose of this application is to propose a sound-absorbing, heat-insulating, and corrosion-resistant composite panel, which has the characteristics of thermal insulation, sound absorption and noise reduction, corrosion resistance, and simple structure.

[0014] Furthermore, the support layer is made of or spliced ​​from a plate, a column block, a plastic honeycomb plate, a metal honeycomb plate, or a light wooden plate that is hollowed out along the thickness direction; or

[0015] Made of polyurethane, PP, PVC, PET, XPS plastic materials by injection molding, pressing or extrusion.

[0016] Through the above technical solution, the structural strength of the supporting layer is guaranteed, while the composite board is made lightweight and the sound insulation and noise reduction performance is improved.

[0017] Furthermore, the support layer is made of a plastic honeycomb panel, wherein sound-absorbing cotton is filled or bonded to the inner wall of the honeycomb panel, or non-woven fabric is bonded to one side or both sides of the plastic honeycomb panel;

[0018] The non-woven fabric is made of one or more of polyester fiber, polyester fiber, synthetic fiber, or cotton, linen, and glass fiber combined with each other;

[0019] The nonwoven fabric has a thickness of 0.02 to 1.5 mm.

[0020] Through the above technical scheme, the bonding strength between the supporting layer and the adhesive layer can be further improved and it is not easy to fall off or bulge. At the same time, the composite board is lightweight, has high strength, does not bulge, and each layer has strong adhesion and is not easy to fall off, thereby improving the sound insulation and noise reduction effect.

[0021] Furthermore, the gel coat layer is made of one or more materials selected from epoxy resin, polyurethane resin, unsaturated resin or saturated resin, and a pattern is arranged on a side of the gel coat layer away from the support layer.

[0022] Through the above technical solution, the gel coat itself has anti-corrosion properties, and setting a texture pattern can also improve the anti-slip and aesthetic properties of the gel coat.

[0023] Furthermore, the adhesive layer is one or a combination of single-component glue, two-component glue, hot melt glue, etc.

[0024] Furthermore, the bonding layer, the fiber reinforcement layer and the gel coat layer are sequentially arranged on both sides of the support layer and are symmetrically arranged.

[0025] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0026] (1) The fiber reinforcement layer can effectively improve the structural strength and thermal insulation performance of the composite board, while the gel coat layer can improve the corrosion resistance of the composite board;

[0027] (2) By adopting a support layer structure in the shape of a column, a hollow plate or a honeycomb, the weight of the composite board itself is reduced while playing a supporting role, thereby achieving lightweight. At the same time, the internal space gap can also play a good noise reduction effect;

[0028] (3) By providing a pattern on the side of the gel coat layer away from the support layer, an anti-slip or aesthetic effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The support layer 1 is configured as a columnar structure, a plate structure, a hollow plate structure or a honeycomb structure according to different functional requirements. The support layer 1 structure in the columnar, hollow plate or honeycomb shape can reduce the weight of the composite board itself while playing a supporting role, achieving lightweight, and the internal space gap can also play a good sound insulation and noise reduction effect.

[0036] In the embodiment of the present application, the support layer 1 can be made of a plate, a column block, a plastic honeycomb panel 6, a metal honeycomb panel, or a light wood material that is hollowed out along the thickness direction, or can be made by injection molding, pressing, or extrusion of polyurethane, PP, PVC, PET, or XPS plastic material. Preferably, it is made of a plastic honeycomb panel 6 or a metal honeycomb panel.

[0037] Further preferably, Figure 2 As shown, a non-woven fabric 5 is bonded to one or both sides of a plastic honeycomb panel 6. The above technical solution ensures the structural strength of the support layer 1. The non-woven fabric 5 improves the bonding strength between the support layer 1 and the adhesive layer 2 and makes it less likely to fall off or bulge. At the same time, the composite panel is lightweight and the sound insulation and noise reduction performance is improved.

[0038] In practical applications, combined with Figure 3 As shown, the supporting layer 1 made of the plastic honeycomb panel 6 is filled with sound-absorbing cotton 7, or the inner wall of the honeycomb panel is bonded with the sound-absorbing cotton 7, or the non-woven fabric 5 is bonded with one or both sides of the plastic honeycomb panel 6. The non-woven fabric 5 is made of one or more of polyester fiber, polyester fiber, synthetic fiber, or cotton, linen, and glass fiber.

[0039] The fiber reinforced layer 3 includes fiber filaments, fiber felt or fiber woven cloth, and resin impregnated on the fiber filaments, fiber felt or fiber woven cloth. The resin is configured as an unsaturated resin, and can also be configured as an epoxy resin, a polyurethane resin, a saturated resin, or a combination of one or more materials. The fiber filaments, fiber felt or fiber woven cloth can be made of one or more combinations of glass fiber, polyester fiber, carbon fiber, basalt fiber, etc. In the above technical solution, the fiber felt or fiber woven cloth has a high tensile strength, and can be fully contacted and fused with the resin, playing the role of heat preservation, sound absorption, and shock absorption, improving the structural strength of the composite board while improving the thermal insulation and noise reduction performance of the composite board.

[0040] In the implementation mode of the present application, the bonding layer 2 preferably adopts one or more combinations of single-component glue, two-component glue, hot melt adhesive, etc., and the thickness of the bonding layer 2 is 0.01-2.0 mm, preferably 0.03 mm-1.78 mm. The thickness of the fiber-reinforced layer 3 is 0.4-3.0 mm, preferably 0.5 mm-2.55 mm. The thickness of the gel coat layer 4 is 0.05-2.5 mm, preferably 0.08 mm-2.35 mm. The thickness of the non-woven fabric 5 is 0.02 mm-1.5 mm, preferably 0.03 mm-1.41 mm. The above-mentioned technical solution adopts the fiber-reinforced layer 3 to effectively improve the structural strength and thermal insulation performance of the composite board, and the gel coat layer 4 can improve the corrosion resistance of the composite board without cracking. The bonding layer 2 improves the bonding strength between the supporting layer 1 and the bonding layer 2 through the non-woven fabric 5 and is not easy to fall off or bulge. At the same time, the composite board is lightweight and the sound insulation and noise reduction performance is improved.

[0041] In detail, the gel coat layer 4 is made of one or more materials of epoxy resin, polyurethane resin, unsaturated resin or saturated resin. The side of the gel coat layer 4 away from the support layer 1 is provided with a pattern to achieve an anti-slip or aesthetic effect. In a general implementation, it can also be a flat surface without a pattern.

[0042] In a specific embodiment, the adhesive layer 2 , the fiber reinforcement layer 3 , and the gel coat layer 4 are sequentially arranged on one side of the support layer 1 .
