Abstract

Disclosed herein are a protective film having a structure capable of protecting an adherend and an electronic appliance including the same. The protective film includes a protection layer comprising polyolefin, and an adhesive layer laminated on the protection layer and comprising a silicone adhesive.

First claim

What is claimed is:

1. A protective film comprising:
a protection layer comprising polyolefin;
an adhesive layer laminated on the protection layer and comprising a silicone adhesive;
a base layer laminated on the protection layer to allow the protection layer to be disposed between the adhesive layer and the base layer; and
a bonding layer disposed between the base layer and the protection layer.

2. The protective film according to claim 1 , wherein the polyolefin comprises at least one of oriented polypropylene, polyethylene, and polyurethane.

3. The protective film according to claim 1 , wherein the protection layer comprises:
a first layer laminated on the adhesive layer and comprising random-polypropylene;
a third layer comprising homo-polypropylene; and
a second layer disposed between the first layer and the third layer and comprising ter-polypropylene.

4. The protective film according to claim 1 , wherein the silicone adhesive comprises a low-temperature curing silicone adhesive.

5. The protective film according to claim 1 , wherein the base layer comprises at least one of polyethylene terephthalate, biaxially oriented polypropylene, polycarbonate, polyamide, and polyurethane.

6. The protective film according to claim 1 , wherein the bonding layer comprises at least one of an epoxy-based, urethane-based, rubber-based, and acrylic-based resin.

7. The protective film according to claim 4 , wherein the low-temperature curing silicone adhesive cures at a temperature of from 65° C. to 95° C.

8. The protective film according to claim 4 , wherein the low-temperature curing silicone adhesive has heat resistance at a temperature of 200° C. or less.

9. An electronic appliance comprising:
a main body configured to define an appearance;
an inner space formed inside the main body; and
a protective film detachably adhered to at least one portion of the main body,
wherein the protective film comprises:
a protection layer comprising polyolefin;
an adhesive layer laminated on the protection layer and comprising a silicone adhesive; and
a base layer laminated on the protection layer to allow the protection layer to be disposed between the adhesive layer and the base layer.

10. The electronic appliance according to claim 9 , wherein the main body has a metallic region, and
the protective film is adhered to at least one portion of the metallic region.

11. The electronic appliance according to claim 9 , wherein the polyolefin comprises at least one of oriented polypropylene, polyethylene, and polyurethane.

12. The electronic appliance according to claim 9 , wherein the protection layer comprises:
a first layer laminated on the adhesive layer and comprising random-polypropylene;
a third layer comprising homo-polypropylene; and
a second layer disposed between the first layer and the third layer and comprising ter-polypropylene.

13. The electronic appliance according to claim 12 , wherein the first layer, the second layer, and the third layer have a thickness ratio of 1 to 4:2 to 8:1 to 4.

14. The electronic appliance according to claim 9 , wherein the silicone adhesive comprises a low-temperature curing silicone adhesive curing at a temperature of from 65° C. to 95° C.

15. The electronic appliance according to claim 9 , wherein the base layer comprises at least one of polyethylene terephthalate PET, biaxially oriented polypropylene OPP, polycarbonate PC, polyamide PA, and polyurethane PU.

16. The electronic appliance according to claim 9 , wherein the protective film further comprises a bonding layer disposed between the base layer and the protection layer.

17. The electronic appliance according to claim 16 , wherein the bonding layer comprises at least one of an epoxy-based, urethane-based, rubber-based, and acrylic-based resin.

18. A protective film comprising:
a protection layer comprising polyolefin; and
an adhesive layer laminated on the protection layer and comprising a silicone adhesive, wherein the protection layer comprises:
a first layer laminated on the adhesive layer and comprising random-polypropylene;
a third layer comprising homo-polypropylene; and
a second layer disposed between the first layer and the third layer and comprising ter-polypropylene.
