Description

Technical Field

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

[0002] For sound-absorbing and sound-insulating materials, the main body is a cotton layer. An aluminum foil layer can be laminated on the surface of the cotton layer for structural reinforcement, protection and moisture protection. For the field of sound insulation and sound absorption, perforations can be arranged on the aluminum foil so that the aluminum foil can participate in the sound insulation and sound absorption work. However, due to its insufficient mechanical strength, it is prone to damage and affects its service life. Summary of the Invention

[0003] The purpose of this invention is to provide a perforated reinforced aluminum foil for sound insulation. Through the design of the aluminum foil layer, the reinforcing layer and the lining layer, the strength of the aluminum foil can be greatly improved. Through the design of micropores and openings, sound-absorbing holes can be formed in the reinforced aluminum foil, thereby improving the sound insulation and noise reduction capabilities of the aluminum foil.

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

[0005] This utility model is a perforated reinforced aluminum foil for sound insulation, comprising a tooling layer, an aluminum foil layer, a reinforcing layer and a lining layer;

[0006] The tooling layer is provided with a number of preset protrusions, the liner is provided with a number of openings, the tooling layer is movably disposed on the lower surface of the liner, and the preset protrusions penetrate the openings;

[0007] The reinforcing layer is a fiberglass mesh layer, which is disposed on the upper surface of the liner, and several of the pre-set protrusions pass through the mesh of the reinforcing layer.

[0008] The aluminum foil layer is disposed on the upper surface of the reinforcing layer, and the aluminum foil layer has a number of micropores. The reinforcing layer is bonded between the aluminum foil layer and the lining layer by an adhesive layer.

[0009] The reinforcing layer forms a mesh of raised ribs on the aluminum foil layer, the preset protrusion forms an outer protrusion on the aluminum foil layer, and the adhesive layer is located away from the gap of the reinforcing layer at the preset protrusion, the opening at the preset protrusion, and the micropore at the outer protrusion on the aluminum foil layer.

[0010] Furthermore, an inner silencing hole is formed between the outer protrusion and the liner at the mesh gap of the reinforcing layer, and the top and bottom ends of the inner silencing hole are respectively connected to the micropore and the opening.

[0011] Furthermore, an adhesive layer forms a connection point between the aluminum foil layer and the liner, and the connection point is located at the mesh gap of the reinforcing layer.

[0012] Furthermore, the tooling layer metal layer and the preset protrusion are integrally connected with the tooling layer.

[0013] Furthermore, the pre-set protrusion has a rounded or chamfered edge at the end away from the tooling layer.

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

[0015] 1. This utility model, through the design of aluminum foil layer, reinforcing layer and lining layer, can greatly improve the strength of aluminum foil. Through the design of micropores and through-holes, sound-absorbing holes can be formed in the reinforcing aluminum foil, thereby improving the sound insulation and noise reduction capabilities of aluminum foil.

[0016] 2. Through the design of the tooling layer, this utility model can be inserted into the reinforced aluminum foil during the composite process, avoiding the problem of the composite adhesive clogging the holes. At the same time, it can separate the ribs of the reinforced layer, keeping the ribs of the reinforced layer away from the opening, so that the sound-absorbing holes are unobstructed. Compared with the process of drilling holes after the reinforced aluminum foil is composited, it ensures the quality and integrity of the reinforced layer, and will not cause defects due to drilling, thus ensuring the strength of the reinforced aluminum foil.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
