Description

Technical Field

[0001] This utility model belongs to the field of composite material technology, and in particular relates to a sound-insulating perforated aluminum foil reinforced composite material. Background Technology

[0002] For sound insulation composite materials, the main body is a cotton layer. An aluminum foil layer can be laminated on the surface of the cotton layer to enhance the surface strength and flatness of the cotton layer. If perforated aluminum foil is added, the sound insulation and noise reduction effect can be further improved. However, the composite of a single layer of perforated aluminum foil will result in strength loss and difficulty in lamination due to the holes. Summary of the Invention

[0003] The purpose of this utility model is to provide a sound-insulating perforated aluminum foil reinforced composite material. The design of the reinforced aluminum foil surface and the design of the lining facilitate the layout of the reinforced layer, and facilitate a stable and flat composite connection with the cotton body while ensuring composite strength. The design of the through-holes on the lining, the mesh on the reinforced layer and the dense holes on the aluminum foil layer can form a large number of holes on the reinforced aluminum foil surface. The presence of holes can further improve the sound absorption effect, and the presence of the reinforced layer can improve the material strength and flatness.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a sound-insulating perforated aluminum foil reinforced composite material, comprising a cotton layer and a reinforced aluminum foil surface;

[0006] The reinforced aluminum foil surface includes a lining layer, a reinforcing layer, and an aluminum foil layer;

[0007] The reinforcing layer is a fiberglass mesh fabric, and the reinforcing layer is composited between the lining layer and the aluminum foil layer;

[0008] The cotton layer is laminated on the lower surface of the lining;

[0009] The aluminum foil layer has a number of dense holes, and the lining layer has a number of rows of evenly spaced openings. The openings are strip-shaped or waist-shaped grooves. The dense holes of the aluminum foil layer, the mesh of the reinforcing layer, and the openings of the lining layer form overlapping points.

[0010] Furthermore, a composite point is formed between the aluminum foil layer and the liner, and the composite point is at the mesh gap of the reinforcing layer.

[0011] Furthermore, the lining layer is a flat layer, and the aluminum foil layer has an upwardly convex mesh rib surface formed by the reinforcing layer.

[0012] Furthermore, the width and length of the reinforced aluminum foil surface are consistent with the width and length of the cotton layer, respectively.

[0013] Furthermore, the cotton layer is a sound-absorbing cotton body or a sound-insulating cotton body.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a reinforced aluminum foil surface design. The lining design facilitates the placement of the reinforcement layer and enables a stable and flat composite connection with the cotton body, ensuring composite strength. The combination of the through-hole design on the lining, the mesh gaps on the reinforcement layer, and the dense holes on the aluminum foil layer creates a large number of holes on the reinforced aluminum foil surface. The presence of these holes further enhances the sound absorption effect, and the reinforcement layer improves the material strength and flatness.
