Description

Automotive interior decorating film

Technical Field

The utility model relates to a decorating film especially relates to an automotive interior decorating film.

Background

The automobile is an important transportation tool in modern society, and with the development of society, the requirements of people on the safety, comfort, economy and environmental protection of the automobile are continuously improved, and the details of the interior decoration of the automobile are more emphasized;

in automobile sales, the interior of the vehicle plays a critical role in user experience, and even directly determines the purchasing desire of consumers, so the design of the interior of the vehicle tends to be refined, beautiful and environment-friendly.

Because the automobile interior decoration film in the prior art is not enough in toughness, if the whole automobile interior decoration film is forcedly adhered to an automobile interior, the bending part can be not tightly adhered or even broken, and therefore the automobile interior decoration film is often designed into a decoration block. The decoration block comprises a decoration block body, a membrane is fixedly connected inside the decoration block body, a coating layer is arranged at the bottom of the membrane, a printing layer is fixedly connected to the bottom of the coating layer, an adhesive glue is fixedly connected to the bottom of the printing layer, and a plastic body is fixedly connected to the bottom of the adhesive glue. The decorative block can only be attached to the partial area of the automobile interior trim for decoration, and can not cover the corner angle with the bent break angle, so that the consistency and the attractiveness of the automobile interior trim are affected.

Therefore, there is a need for an improvement of the related art automotive interior film.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide an automotive interior decorating film, have stronger toughness, crooked, the dog-ear department that can perfectly laminate automotive interior promotes automotive interior's pleasing to the eye degree.

In order to realize the technical effects, the utility model adopts the technical scheme that: the utility model provides an automotive interior decorative film, includes substrate layer, installation glue film and sclerosis layer, the installation glue film set up in one side of substrate layer, the sclerosis layer set up in the opposite side of substrate layer, its characterized in that, the sclerosis layer with be provided with the layer of toughening between the substrate layer.

The preferred technical scheme is that the toughening layer comprises PETG.

The preferred technical scheme is that the toughening layer is a PETG and PET co-extrusion composite layer or a PETG and PET and PETG co-extrusion composite layer or a PETG layer.

The preferable technical scheme is that a composite glue layer is clamped between the base material layer and the toughening layer.

The preferable technical scheme is that an image-text layer is arranged between the base material layer and the toughening layer.

The preferable technical scheme is that the base material layer is a PVC layer.

The preferable technical scheme is that the thickness ratio of the hardening layer, the toughening layer and the PVC layer is (0.025-0.1): (0.025-1): 1.

The utility model has the advantages and the beneficial effects that: the utility model discloses the toughness of toughening layer can effectively strengthen the decorating film among the automotive interior decorating film, and the limit corner angle of automotive interior that can laminate more compares with prior art, to the crooked dog-ear department of automotive interior, no longer has the inseparable condition of breaking even decorating film of laminating.

FIG. 2 is a schematic structural view of an embodiment 2 of the decorative film for automobile interiors according to the present invention;

FIG. 3 is a schematic structural view of an embodiment 3 of the decorative film for automobile interiors according to the present invention;

in the figure: 1. a hardened layer; 2. a toughening layer; 21. a PETG layer; 22. a PET layer; 3. compounding a glue layer; 4. an image-text layer; 5. a PVC layer; 6. installing a glue layer; 7. and a release layer.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Hardened layer

The hardened layer can be made of polymethyl methacrylate or acrylic ester, preferably polyurethane modified acrylic acid, has the characteristics of high hardness and low possibility of abrasion, and simultaneously has flexibility, extremely high hydrophobicity and easiness in cleaning; and can also absorb harmful gases such as formaldehyde and the like in the vehicle.

Composite glue layer

The composite adhesive layer is preferably made of polyurethane composite adhesive, and the toughening layer and the PVC layer have larger polarity difference, so that the toughening layer and the PVC layer cannot be well attached together by a conventional method and need to be bonded by the composite adhesive layer; as an equivalent alternative, the toughening layer and the PVC layer may also be attached together by hot pressing at 150 degrees celsius.

Picture and text layer

The image-text layer is generally an ink layer, the material of the ink layer can be polyurethane, polyamide resin and chlorinated polypropylene, and polyurethane modified chlorinated polypropylene is preferred, so that the adhesion is good, the gloss is good, the high temperature resistance is realized, and the compounding with PETG is not influenced.

Substrate layer

The substrate layer is the PVC layer, adopts the fire-retardant material of V0 grade, can avoid arousing the auto fire spontaneous combustion risk because of the getting on fire of decorating film, and possesses waterproof anticorrosive ultraviolet resistance's advantage.

Mounting glue layer

The mounting glue layer is reaction type flame retardant glue, and the ultraviolet absorbent is added in the glue layer, so that more than 99% of ultraviolet rays can be blocked, chemical volatilization caused by product aging can be effectively prevented, and the service life of the product is prolonged.

The surface of the mounting adhesive layer is also provided with a release layer in an adhering way, and the release layer is used for protecting the mounting adhesive layer before production, transportation and use.

Example 1

As shown in fig. 1, the automotive interior film of embodiment 1 includes a hardened layer 1, a toughening layer 2, a composite adhesive layer 3, an image-text layer 4, a PVC layer 5, a mounting adhesive layer 6, and a release layer 7, which are sequentially stacked and connected from outside to inside.

The toughening layer 2 is a PETG layer 21.

The thickness of the hardening layer 1 is 5-10 μm, the thickness of the toughening layer 2 is 50-100 μm, and the thickness of the PVC layer 5 is 100-200 μm.

Example 2

As shown in fig. 2, example 2 is based on example 1, except that the toughening layer 2 is a co-extruded composite layer of a PETG layer 21 and a PET layer 22 and a PETG layer 21.

Example 3

As shown in fig. 3, example 3 is based on example 1, except that the toughening layer 2 is a co-extruded composite layer of a PETG layer 21 and a PET layer 22, the PET layer 22 being adjacent to the PVC layer 5.

In the embodiments 1 to 3, the thickness of the toughening layer 2 is the lowest under the condition of the same thickness, the PETG layer 21 in the embodiment 3 has the lowest thickness and the lowest cost, and simultaneously, the toughness of the automobile interior decoration film is considered, and the use effect of the automobile interior decoration film is not influenced;

the hardened layer 1 outside the toughening layer 2 has the characteristic of high hardness and difficulty in abrasion, can play a good role in protecting the toughening layer 2, and effectively prevents the toughening layer 2 from being scratched and losing the toughening effect.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
