Referring to the drawings, a base layer 30, a partition wall layer 40 formed on the upper surface of the base layer 30, a gloss layer 20 formed on a lower bottom surface of the base layer 30, and the partition wall It comprises a protective layer 50 formed on the top of the layer 40, and an adhesive layer 10 formed on the bottom of the gloss layer 20.

The base layer 30 is a film of a transparent material, preferably, a film for UV (ultraviolet) imprinting.

The partition layer 40 includes a partition wall 41 formed to be spaced apart at regular intervals on the upper surface of the base layer 30 and an insert 42 formed between the partition walls 41.

The partition wall 41 uses an acrylic monomer resin. The embodiment of the present invention uses an acrylate resin.

In addition, the insert 42 is made of an acrylic monomer (monomer) resin. The embodiment of the present invention uses an acrylate resin.

In the first embodiment of the partition wall layer 40 of the present invention, a material of the insert 42 is made of a transparent resin, and the refractive indexes of the partition 41 and the insert 42 are different from each other.

At this time, the refractive index of the partition wall 41 of the first embodiment of the partition layer 40 of the present invention is 0.5 or more and less than 0.7, and the refractive index of the insert 42 is 0.7 or more and 0.9 or less. More preferably, the refractive index of the partition wall 41 is 0.5, and the refractive index of the insert 42 is 0.7.

In the second embodiment of the partition layer 40 of the present invention, the material of the insert 42 uses a translucent resin and contains a matting agent.

The adhesive layer 10 is a layer coated with an adhesive in order to attach the film of the present invention to interior materials of automobile interiors.

The protective layer 50 is a layer formed to protect the structure of the lower partition wall layer 40 and increase the durability of the film, and laminating a thin transparent film on the upper surface of the partition wall layer 40 Is formed.

3A and 3B are manufacturing process diagrams of a film for attaching automobile interior materials of the present invention.

Referring to the drawings, the film for attaching an automobile interior material of the present invention transports a base layer film F made of a transparent material constituting the base layer 30 through a conveyor (not shown) using a conventional roll. In order to form the partition wall 41 of the partition wall layer 40, the resin received from the feeder 100 containing the acrylic monomer resin is supplied onto the base layer film (F), and then on the base layer film (F). Resin (R) is applied uniformly with a constant thickness.

In the embodiment of the present invention, a material used as the base layer film (F) was a PC-PMMA (Polycarbonate-Poly methyl methacrylate) coextrusion film, and a UV (ultraviolet) imprinting film was used.

The UV imprinting method applies a thermoplastic resin or a photo-curable resin on a film or a substrate, and then applies pressure to the resin using a mold having a pattern, and cures it using an electron beam or ultraviolet rays to form the pattern formed on the mold. It is a well-known pattern transfer technique.

This imprinting method has the advantage of high production speed because it can be continuously produced using a roll base having a pattern.

Subsequently, the resin R uniformly coated on the base layer film F as described above is passed through the smoothing roller 110 to flatten the surface of the resin R by the smoothing roller 110.

Then, the base layer film F in the state where the resin R is applied is supplied to the bottom of the pattern roller 120. Then, the pattern roller 120 having the pattern 121 of the partition wall 41 of the partition wall layer 40 formed on the surface is rotated at a constant speed in a predetermined direction and pressure is applied onto the resin R.

Subsequently, when pressure is applied onto the resin R by the pattern roller 120, the pattern 121 formed on the surface of the pattern roller 120 is transferred onto the resin R by the pressure of the roller 120. , The transferred pattern forms the partition walls 41. The width w of the partition wall 41 formed is approximately 50 micrometers to 100 micrometers.

At this time, electron beams or ultraviolet rays are injected onto the resin R that has passed through the pattern roller 120 to cure the patterns formed on the resin R.

Subsequently, in order to fill the insert 42 between the partition walls 41 formed on the film F, an insert feeder 140 containing resin for forming the insert of the film F using the transfer roller 130 ) Is transferred to the lower end, and the resin is supplied from the insert feeder 140 onto the base layer film (F), coated, and cured to fill the insert 42 between the partition walls 41.

At this time, in the first embodiment of the present invention, the insert 42 uses a transparent acrylic monomer resin.

In addition, in the second embodiment of the present invention, the insert 42 uses a semi-transparent acrylic monomer resin, and a spherical silica of 1 micrometer or more and 5 micrometers or less as a matting agent is inserted into the resin (42). ) Use a resin mixed in a weight ratio of 5-7% compared to the total weight ratio.

Subsequently, the base layer film F formed with the partition wall 41 is continuously transported by the rear-end transfer roller 150 to brighten the interior of the vehicle interior on the lower bottom surface of the film F by the glossy layer forming machine 160. In order to impart a clear or metallic feeling, a metallic material such as chromium is plated, painted, or deposited to form a glossy layer 20, and an adhesive layer laminating device 170 forms a film (F) under the glossy layer 20. The adhesive layer 10 is formed by laminating an adhesive layer in order to attach it to the interior material of a vehicle interior.

In addition, after the adhesive layer 10 is formed, to protect the structure of the partition wall layer 40, the partition wall 41 and the insert 42 is formed and to increase the durability of the film by a conventional film laminating device 180 A protective layer 50 is formed by laminating a transparent material film on the upper surface of the barrier layer 40.

Next, the operating state of the film for attaching automobile interior materials of the present invention manufactured by the above-described process will be described.

4 and 5 are operating state diagrams of the film for attaching automobile interior materials of the present invention.

First, referring to FIG. 4, FIG. 4 is a first embodiment of the partition wall layer 40 of the present invention, as described above, using a transparent resin for the material of the insert 42, the partition wall 41 and It is an embodiment in which the refractive indexes of the inserts 42 are formed to be different from each other.

Therefore, when the film attached to the interior material of the vehicle interior is viewed vertically from the front (for example, when the driver of the car is seated in the driver's seat and looks at the interior material), the light reflected from the gloss layer 20 is applied to the base layer ( 30) passing through vertically, and then having a straight path (L1) that vertically passes through the partition wall 41 of the partition wall layer 40, no refraction in the path of light is generated so that the bright metal of the glossy layer 20 The gloss and texture of the film is transmitted through the film.

On the other hand, when the film is viewed obliquely, the light reflected from the gloss layer 20 forms a first inclined path L2 that transmits the partition 41 of the base layer 30 and the partition layer 40 at an inclined angle. Then, when passing through the insert 42, the refractive index f1 of the partition wall 41 of the partition wall layer 40 and the refractive index f2 of the insert 42 are different from each other, and thus, due to the difference in the refractive index between both media, The path forms a second inclined path (L3) that is inclined at a predetermined angle from the boundary between the partition wall (41) and the insert (42), so that the first inclined path (L2) and the second inclined path (L3) are different inclined angles. As will proceed.

Therefore, the light generated from the gloss layer 20 is not clearly shined on the outside mirror (not shown) positioned at a certain angle with the interior material of the automobile interior, so that the bright metal feeling by the gloss layer 20 is prevented. It is possible to prevent the reflection phenomenon in which the portion of the interior material provided is projected onto the outside mirror.

Next, referring to FIG. 5, FIG. 5 is a second embodiment of the partition layer 40 of the present invention, as described above, the material of the insert 42 is made of semi-transparent resin but made of spherical silica. It is a configuration having an insert 42 composed by mixing the matting agent in a weight ratio of 5-7% compared to the total weight ratio of the insert 42. These matting agents serve to scatter light.

Therefore, as described above, when the film attached to the interior material of the vehicle interior is viewed vertically from the front (for example, when the driver of the car is seated in the driver's seat and looks at the interior material), the light reflected from the gloss layer 20 is reflected. Since the base layer 30 passes vertically, and then has a straight path L4 that vertically passes through the partition 41 of the partition layer 40, refraction in the path of light is not generated, so that the glossy layer 20 The luster and texture of the bright metal of the film is transmitted through the film.

On the other hand, when the film is viewed obliquely, after forming the inclined path L5 through which the light reflected from the gloss layer 20 passes through the base wall 30 and the partition wall 41 of the partition wall layer 40 at an inclined angle. , When passing through the insert 42, light is scattered by the matting agent included in the insert 42 to form a plurality of scattering paths L6, L7, L8, while having a certain angle with the interior material of the vehicle interior Since the light generated from the gloss layer 20 is scattered on the outside mirror (not shown), which is located, and is not clearly reflected, a portion of the interior material provided with a bright metallic feeling by the gloss layer 20 is provided to the outside mirror. It is possible to prevent the reflection phenomenon from being reflected in advance.
