Embodiment 1

[0047] Such as figure 1As shown, a lightweight automotive damping film, including a bonding layer 1 and a reinforcing layer 2, a number of flexible columns 3 are arranged between the bonding layer 1 and the reinforcing layer 2, and the flexible columns 3 are perpendicular to the bonding layer 1 and the reinforcing layer 2 .

[0048] In this embodiment, several flexible columns 3 are arranged between the adhesive layer 1 and the reinforcement layer 2, and the adhesive layer 1 and the reinforcement layer 2 form a cavity through the support of the flexible columns 3. The present invention adopts a new structure, and the cavity The existence of finiteness reduces the density and quality of the damping film. At the same time, due to the existence of the cavity, the damping film can play a better effect of cold and heat insulation. Several flexible columns 3 in the cavity increase the sound absorption of the damping film. area, so that the damping film can have a better absorption ...

Embodiment 2

[0054] Further, the bonding layer 1 is pressure-sensitive adhesive, the reinforcing layer 2 is made of laminated aluminum foil, and the material of the flexible column 3 includes PP and / or EPDM and / or TPE.

[0055] In this embodiment, the bonding layer 1 is made of pressure-sensitive adhesive, which has high viscosity and will not be degummed during use, and the bonding process of the pressure-sensitive adhesive is convenient, making the damping film easy to use and strengthening Layer 2 is made of aluminum foil. The aluminum foil has excellent corrosion resistance and plasticity. At the same time, the aluminum foil has high strength, high tensile strength, and low tear strength. It is suitable for the application scene of damping film. The glue attached to the surface of the aluminum foil can make The flexible column 3 is bonded to the aluminum foil, which simplifies the production process.

[0056] The flexible column 3 is made by mixing PP and / or EPDM and / or TPE. Since the ...

Embodiment 3

[0058] Such as Figure 1 ~ Figure 3 As shown, a manufacturing process of a lightweight automobile damping film is used to produce a lightweight automobile damping film,

[0059] Step 1: heating the raw material, extruding the raw material into the mold after heating, and making the flexible column 3 after cooling,

[0060] Step 2: arrange the flexible pillars 3, and press several arranged flexible pillars 3 onto the bonding layer 1,

[0061] Step 3: Press the reinforcing layer 2 onto the end of the flexible column 3 farther from the adhesive layer 1 .

[0062] In this embodiment, when making lightweight automobile damping film, the raw materials are melted first, and the raw materials are squeezed into the mold, and the flexible columns 3 are formed after the raw materials are cooled. The arrangement is regular, and the arranged flexible columns 3 are pressed onto the adhesive layer 1, and then the reinforcing layer 2 is laid and combined with the adhesive layer 1 to compres...

Abstract

The invention belongs to the technical field of damping rubber sheets and provides a light-weight automobile damping rubber sheet and a manufacturing process and device thereof. The light-weight automobile damping rubber sheet comprises a bonding layer and an enhancement layer. Multiple flexible columns are arranged between the bonding layer and the enhancement layer and are perpendicular to the bonding layer and the enhancement layer. The light-weight automobile damping rubber sheet further comprises an isolation layer arranged on the bonding layer. The isolation layer and the flexible columns are located on the two sides of the bonding layer. Pressing melting columns are arranged at the ends of the flexible columns and connected with the bonding layer and / or the enhancement layer. The pressing melting columns and the flexible columns are collinear. The diameter of each pressing melting column is larger than that of each flexible column. By the adoption of the above technical scheme,the problem that a damping rubber sheet in the prior art is large in density and mass is solved.

Description

technical field [0001] The invention belongs to the technical field of damping film, and relates to a light-weight automobile damping film and its manufacturing process and equipment. Background technique [0002] Automobile damping film usually uses asphalt as raw material. When using it, the automobile damping film is usually attached to the inner surface of the car body. As a viscoelastic material, the car damping film is closely attached to the steel plate wall of the car body, mainly to reduce noise and reduce The role of vibration, play a damping role, [0003] According to the installation process, the damping film is mainly divided into three types: hot-melt damping film, self-adhesive damping film and magnetic suction damping film. [0004] a) Hot-melt damping film refers to the damping film pasted on the vehicle body by baking process; [0005] b) Self-adhesive damping film refers to a damping film that is coated with a layer of pressure-sensitive adhesive on the...
