According to another embodiment of the present invention, in the sunroof film according to the present invention, the protruding portion may take the form of a triangle, a convex semicircle or a wavy shape in cross section.

According to another embodiment of the present invention, in the sunroof film according to the present invention, the protrusions are formed by injection molding processing or etching.

According to another embodiment of the present invention, the sunroof film according to the present invention comprises a plurality of protrusion forming members and the first film layer and a plurality of protrusion forming members positioned parallel to the outer surface with a predetermined interval on the upper surface of the first film layer. A protrusion is formed by including a film layer and a second film layer covering the protrusion forming member.

According to another embodiment of the present invention, in the sunroof film according to the present invention, the protruding forming member is characterized in that the cross-section is in the form of a triangular shape, a convex semicircle or an upper surface.

The present invention is attached to the sunroof of the vehicle so that the protrusion is located in the front and rear direction of the vehicle, the rain on the vehicle equipped with the sunroof film when the sunroof is opened and the water on the sunroof film between the protrusions Sliding down quickly and opening the sunroof has the effect of minimizing the amount of water entering the vehicle.

In addition, the present invention has the effect that can be easily generated by using the protrusion forming member.

Hereinafter, with reference to the accompanying drawings, the sunroof film according to the present invention will be described in detail. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Unless defined otherwise, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs and, if conflict with the meaning of the terms used herein, It follows the definition used in the specification.

1 is a perspective view of a sunroof film according to an embodiment of the present invention, Figure 2 is a cross-sectional view of a sunroof film according to an embodiment of the present invention, Figure 3 is a sunroof film according to another embodiment of the present invention 4 is a cross-sectional view of a sunroof film according to another embodiment of the present invention, Figure 5 is a view showing a state in which the sunroof film according to the invention is attached to the vehicle.

1 to 3, the sunroof film 1 according to an embodiment of the present invention includes a resin layer 11, a protrusion 12, and an adhesive layer 13.

The resin layer 11 is formed of a synthetic resin, and serves to block the transmission of light when the sunroof film is attached to the sunroof. It is preferable that the said resin layer 11 consists of a thermoplastic resin. Examples of the thermoplastic resin that can be used for the resin layer 11 include polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyolefin resins such as polyethylene and polypropylene, polystyrene resins, and polyamides such as nylon 66. Resins, polycarbonate resins, vinyl chloride resins and the like can be used. Among them, polyesters having good impact resistance, heat resistance and strength are preferred, and among the polyester resins, polyethylene terephthalate is most preferable because of low cost and excellent mechanical properties. The resin layer 11 is colored to prevent light transmission, and various additives such as antioxidants, crystal nucleating agents, inorganic particles, organic particles, heat stabilizers, lubricants, infrared absorbers, and ultraviolet absorbers are added to the thermoplastic resin. Can be prepared.

The protrusions protrude in parallel with one side of the upper surface of the resin layer 11, and a plurality of protrusions are positioned parallel to the upper surface with a predetermined interval, so that the rain is not separated between the protrusions even when the vehicle is mounted with the sunroof film. Let it flow down easily. The protruding portion may have various shapes such as a semicircle in which a cross-section is convex toward the upper surface as shown in FIG. 2, a wavy shape as in FIG. 3, and a triangle although not shown.

The adhesive layer 13 is applied to the lower surface of the upper resin layer 11 and dried so that the resin layer 11 can adhere to the sunroof, and is made of a solution including an adhesive, an initiator, a crosslinking agent, and an organic solvent. Adhesives include butyl rubber adhesives, acrylic adhesives, and polyether adhesives. The main composition applied to the most widely used acrylic adhesives is alkyl (meth) acrylate based, among which isopropyl (meth) acrylate (iso) is used. propyl methacrylate), n-butyl methacrylate, t-butyl methacrylate, t-butyl methacrylate, n-octyl methacrylate, iso 1 selected from the group consisting of octyl (meth) acrylate (iso-octyl methacrylate), isononyl (meth) acrylate (iso-nonyl ethacrylate), and stearyl methacrylate (stearyl methacrylate) It may consist of two or more. The adhesiveness of the adhesive depends mainly on the molecular weight, molecular structure, etc. of the polymer chain, and in particular, the acrylic copolymer has a weight average molecular weight of 500,000 to 2 million.

The sunroof film may be heated to a synthetic resin and injected into a mold having a predetermined shape to form the resin layer 11 and the protruding portion, or the resin layer 11 may be dissolved with an acid or the like to form the resin layer 11. Etching may be performed to form protrusions on the substrate.

Referring to FIG. 4, a sunroof film according to another embodiment of the present invention will be described. The sunroof film may have a protrusion forming member 22 having a predetermined shape on an upper surface of the first resin layer 21 at a predetermined interval. Positioned parallel to the outer surface of the first resin layer 21, the second resin layer 23 is melt-compressed on the upper surface of the first resin layer 21 and the protrusion forming member 22 to project the protrusions (24) May be formed. By the shape of the protrusion forming member 22, it is possible to generate a variety of protrusions 24. For example, the protrusion forming member 22 may have various shapes such as a semicircle, a wave shape, a triangle, and the like having a cross-sectional shape. An adhesive layer 25 is formed on the bottom surface of the first resin layer 21.

The sunroof film according to the present invention is attached to the sunroof of the vehicle so that the protrusion is located in the front and rear direction of the vehicle. If the sunroof is opened after the rain on the car equipped with the sunroof film, the water on the sunroof film slides quickly between the protrusions to minimize the amount of water entering the car even when the sunroof is opened. have.

In the above, the Applicant has described various embodiments of the present invention, but these embodiments are merely one embodiment for implementing the technical idea of the present invention, and any changes or modifications may be made to the present invention as long as the technical idea of the present invention is implemented. It should be interpreted as falling within the scope of.
