Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration materials, and in particular relates to a recyclable automobile interior decoration board. Background Art

[0002] The recyclable and reusable automotive interior panels mentioned above can also be used in the home decoration industry and even in office places. The structure of the currently widely used automotive interior panels is usually composed of what is commonly called a core layer, a fabric layer (i.e., "surface layer") bonded to one side of the core layer, and a base fabric layer (i.e., "base layer") bonded to the other side of the core layer. The core layer is usually made of PP glass fiber board and PU foam board. Among them, automotive interior panels with PP glass fiber board as the core layer still occupy a large share of the market. A typical example of such automotive interior panels is the structure of China Patent Authorization Announcement No. CN201484319U (Automobile Roof Interior Panel), which is composed of a fabric layer of chemical fiber needle-punched non-woven fabric, a composite layer (also called "core layer") of low-density short-cut glass reinforced polypropylene made by mixing reinforced polypropylene and low-density short-cut glass fiber and heating and pressurizing, and a base fabric layer of polyester non-woven fabric. The fabric layer and the composite layer, as well as the composite layer and the base fabric layer, are bonded by adhesive layers. However, in recent years, a large number or even all automobile manufacturers tend to use PET fabrics as the aforementioned surface fabrics. As a result, the automobile interior trim panels of the aforementioned patent or similar to the aforementioned patent have different materials between their core layer and fabric, which brings troubles to the redundant materials (scraps) cut off in the process of producing components such as molded automobile roofs (also called "automobile roofs", hereinafter the same) or other components such as the left and right sides of the automobile trunk, clothes racks, bottom guard plates, etc., as well as the recycling and reuse of automobile roof materials and the aforementioned left and right sides of the automobile trunk, clothes racks, bottom guard plates, etc. when the automobile is scrapped, which is not conducive to embodying the spirit of conservation and energy-saving circular economy advocated by the whole society. Utility Model Content

[0003] Based on the above problems, the purpose of the utility model is to provide a recyclable and reusable automobile interior panel, which can not only meet the requirements of automobile manufacturers for the material of the core layer and the material of the surface layer to be consistent, but also meet the requirements of good recyclability and embody the spirit of circular economy.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following scheme: a recyclable and reusable automobile interior panel, which includes a core layer, a surface layer and a bottom layer, the surface layer is combined with the upper side of the core layer, and the bottom layer is combined with the lower side of the core layer, and is characterized in that: the core layer is a PET reinforced board, and the bottom layer is a PET non-woven fabric.

[0005] Preferably, the PET non-woven fabric is directly combined with the PET reinforcement plate.

[0006] Preferably, the PET non-woven fabric is combined with the PET reinforcing plate via a PET non-woven fabric adhesive layer.

[0007] Preferably, the PET reinforced board has a gram weight of 400 to 2500 g / ㎡.

[0008] Preferably, the PET reinforced board is a PET glass fiber board.

[0009] Preferably, the surface layer is a PET or PES film layer.

[0010] Preferably, the PET film layer has a gram weight of 20 to 120 g / ㎡.

[0011] Preferably, the PET non-woven fabric bonding layer has a gram weight of 20 to 120 g / m2.

[0012] Preferably, the PET non-woven fabric has a gram weight of 30 to 180 g / ㎡.

[0013] Preferably, the glass fibers are chopped glass fibers.

[0014] The beneficial effects of the utility model are as follows: since the core layer is a PET reinforced plate and the bottom layer is a PET non-woven fabric, and since automobile manufacturers can combine the PET fabric with the surface layer when making automobile roofs, etc., it not only meets the automobile manufacturers' requirements for consistency between the core layer material, the surface layer material and the bottom layer material, but also meets the requirements for recycling and reuse of the vehicle when it is scrapped, thereby embodying a good conservation-oriented, energy-saving and circular economy spirit.
