1 is a view showing a protective tape for a ship according to a first embodiment of the present invention.

Referring to FIG. 1, a protective tape 100 for a ship includes an adhesive layer 110 and a base layer 150. The protective tape 100 for a ship may be adhered to the surface of the ship 10 coated with the paint 20 so that the adhesive layer 110 of the protective tape 100 for a ship is directly contacted with the paint 20 .

1, a protective tape 100 for a ship is attached to a ship 10 to which a paint 20 is applied. However, the protective tape 100 for a ship has a release liner formed on one surface of the adhesive layer 110 And the adhesive layer 110 may be adhered to the surface of the vessel 10 coated with the paint 20 after the release liner is removed.

The substrate layer 150 comprises ultra-high molecular weight polyethylene (UHMW-PE). Ultrahigh molecular weight polyethylene is a polyethylene having a molecular weight of about 1 million or more, and polyethylene (PE) generally used has a very large molecular weight, compared with a molecular weight of 100,000 to 300,000.

Such ultrahigh molecular weight polyethylene is a thermoplastic polyethylene having excellent impact resistance and resistance to abrasion, low friction coefficient and self-lubricating property. In particular, abrasion resistance is superior to steel. As a result, even if it collides with a fender or the like, there is less damage and it is advantageous to protect the ship.

In addition, ultrahigh molecular weight polyethylene has resistance to chemicals and is very low in absorbency and is suitable for use in water. In addition, it has excellent low-temperature characteristics and can maintain impact resistance and abrasion resistance even at an extremely low temperature.

The substrate layer 150 may have a thickness of from about 200 탆 to about 500 탆, preferably from about 200 탆 to about 400 탆, and more preferably from about 250 탆 to about 300 탆. If the thickness of the base layer 150 is too thin, the ship protection effect can be reduced. On the other hand, if the thickness of the base layer 150 is too thick, it may be difficult for the adhesive layer 110 to maintain adhesion to the vessel 10 coated with the paint 20.

The surface of the base layer 150 adhered to the adhesive layer 110 may be corona-dustproofed to improve the adhesive strength of the adhesive layer 110 and the base layer 150 including ultra-high molecular weight polyethylene. More specifically, a corona salt may be generated using an electric discharge processor to pass through the base layer 150 therebetween to modify the surface.

The adhesive layer 110 may include an adhesive as one layer. This adhesive layer 110 includes an adhesive selected according to the paint 20. This adhesive layer 110 includes at least one of an acrylic adhesive and a silicone adhesive.

The paint 20 applied to the ship 10 is used for antifouling the ship 10 and may be a silicone paint, an acrylic paint or an epoxy paint. However, all kinds of adhesives are not effective for the marine paint 20, which makes it difficult to attach the protective tape to the marine 10 coated with the paint 20.

The adhesive layer 110 according to the present invention may include an adhesive selected according to the paint 20 so that the base layer 150 can be attached to the vessel 10 coated with the paint 20. When the paint 20 is a silicone paint, the adhesive layer 110 includes a silicone-based adhesive. When the paint 20 is an acrylic paint, the adhesive layer 110 includes an acrylic adhesive. In the case of a base paint, the adhesive layer 110 includes an acrylic adhesive or a silicone adhesive.

Thus, the protective tape 100 for a ship according to the present invention can include a base layer 150 including ultrahigh molecular weight polyethylene to protect the surface of the ship from external impact, particularly collision with a fender, ) Is applied to the surface of the vessel 10 coated with the water.

Next, referring to Fig. 2, a protective tape for a ship according to another embodiment will be described. 2 is a view showing a protective tape for a ship according to a second embodiment of the present invention. The contents overlapping with the above-described embodiment may be omitted, and the same reference numerals denote the same components.

2, the marine protective tape 200 includes an adhesive layer 120 and a base layer 150. [ The protective tape for marine 200 may be adhered to the surface of the ship 10 to which the paint 20 is applied. The substrate layer 150 includes ultrahigh molecular weight polyethylene (UHMW-PE).

2 shows a protective tape 200 for a ship attached to a ship 10 to which a paint 20 has been applied. The protective tape 200 for a ship has a release liner formed on one side of the adhesive layer 120 And the adhesive layer 120 may be adhered to the surface of the vessel 10 coated with the paint 20 after the release liner is removed.

The adhesive layer 120 may comprise a plurality of layers. Further, the adhesive layer 120 may be a double-sided adhesive tape. The adhesive layer 120 includes a first adhesive layer 121, a base film 122 and a second adhesive layer 123 and includes a first adhesive layer 121, a base film 122 and a second adhesive layer 123 may be sequentially stacked and arranged. That is, the base film 122 is disposed on the first adhesive layer 121, and the second adhesive layer 123 is disposed on the base film 122.

The first adhesive layer 121 and the second adhesive layer 123 include an adhesive. More specifically, the first adhesive layer 121 and the second adhesive layer 123 each include at least one of an acrylic adhesive and a silicone adhesive.

The first adhesive layer 121 is adhered to the surface of the vessel 10 to which the paint 20 is applied. The adhesive of the adhesive layer 120 is selected according to the paint 20, and preferably the adhesive of the first adhesive layer 121 is selected according to the paint 20. Thereby, the base layer 150 can be attached to the vessel 10 coated with the paint 20.

Preferably, when the paint 20 is a silicone paint, the first adhesive layer 121 includes a silicone adhesive, and when the paint 20 is an acrylic paint, the first adhesive layer 121 contains an acrylic adhesive And the paint 20 is an epoxy paint, the first adhesive layer 121 includes an acrylic adhesive or a silicone adhesive.

The second adhesive layer 123 is bonded to the base layer 150. As the base layer 150 becomes thicker, the protective tape for ships 200 is likely to be separated from the vessel 10 coated with the paint 20. In addition, the adhesive strength of the protective tape 200 for a ship is affected by the external environment such as the winter season, and the protective tape 200 for a ship may be separated by colliding with the fender due to waves or the like. Therefore, the second adhesive layer 123 needs a stronger adhesion force with the base layer 150. [

When the base layer 150 contains ultra-high molecular weight polyethylene, the acrylic adhesive has better adhesion than the silicone adhesive. Therefore, preferably, the second adhesive layer 123 comprises an acrylic adhesive.

The base film 122 serves to support the first adhesive layer 121 and the second adhesive layer 123. The base film 122 may comprise polyethylene terephthalate (PET). However, the present invention is not limited thereto, and it is sufficient to include a material capable of supporting the first adhesive layer 121 and the second adhesive layer 123.

The base film 122 is disposed between the first adhesive layer 121 and the second adhesive layer 123 and may serve as an additional buffer when colliding with the fender. Further, the base film 122 can increase the thickness of the protective tape 200 for the marine vessel, and can more effectively protect the surface of the ship from external impacts.

Next, referring to Fig. 3, a protective tape for a ship according to another embodiment will be described. 3 is a view showing a protective tape for a ship according to a third embodiment of the present invention. The contents overlapping with the above-described embodiment may be omitted, and the same reference numerals denote the same components.

Referring to FIG. 3, the protective tape 300 for a ship includes an adhesive layer 130 and a base layer 150. The protective tape for marine 300 may be adhered to the surface of the ship 10 to which the paint 20 is applied. The substrate layer 150 includes ultrahigh molecular weight polyethylene (UHMW-PE).

3 shows a protective tape 300 for a ship attached to a ship 10 to which a paint 20 is applied. The protective tape 300 for a ship has a release liner formed on one side of the adhesive layer 130 And the adhesive layer 130 may be adhered to the surface of the vessel 10 coated with the paint 20 after the release liner is removed.

The adhesive layer 130 may include a plurality of layers. The adhesive layer 130 includes a first adhesive layer 131, a base film 132, a second adhesive layer 133, a buffer layer 134 and a third adhesive layer 135, and the first adhesive layer 131 ), The base film 132, the second adhesive layer 133, the buffer layer 134, and the third adhesive layer 135 may be sequentially stacked and disposed. That is, a base film 132 is disposed between the first adhesive layer 131 and the second adhesive layer 133, and a buffer layer 134 is provided between the second adhesive layer 133 and the third adhesive layer 135 .

The first adhesive layer 131, the second adhesive layer 133, and the third adhesive layer 135 include an adhesive. More specifically, the first adhesive layer 131, the second adhesive layer 133, and the third adhesive layer 135 each include at least one of an acrylic adhesive and a silicone adhesive.

The first adhesive layer 131 is adhered to the surface of the vessel 10 coated with the paint 20. The adhesive of the adhesive layer 130 is selected according to the paint 20, and preferably the adhesive of the first adhesive layer 131 is selected according to the paint 20. As a result, the first adhesive layer 131 can also have an adhesive force to the ship 10 coated with the paint 20.

Preferably, when the paint 20 is a silicone paint, the first adhesive layer 131 includes a silicone adhesive, and when the paint 20 is an acrylic paint, the first adhesive layer 131 contains an acrylic adhesive And the paint 20 is an epoxy paint, the first adhesive layer 131 includes an acrylic adhesive or a silicone adhesive.

The second adhesive layer 133 serves to bond the base film 132 and the buffer layer 134 together. Preferably, the second adhesive layer 133 includes an acrylic adhesive.

The third adhesive layer 135 is bonded to the base layer 150. In order to prevent separation of the vessel 10 and the base layer 150, the third adhesive layer 135 needs a stronger adhesion force with the base layer 150. [ Thus, preferably, the third adhesive layer 135 comprises an acrylic adhesive.

The base film 132 serves to support the first adhesive layer 131, the second adhesive layer 133, the buffer layer 134, and the third adhesive layer 135. The base film 132 may comprise polyethylene terephthalate (PET). However, the present invention is not limited to this, and it suffices to include a material capable of supporting the first adhesive layer 131, the second adhesive layer 133, the buffer layer 134, and the third adhesive layer 135. Further, the base film 132 can increase the thickness of the marine protective tape 300 and can more effectively protect the surface of the ship from external impacts.

The buffer layer 134 further serves to buffer when colliding with the fender. The buffer layer 134 includes a foam having a closed cell structure. Such a foam absorbs external pressure and septation and can prevent damage due to collision.

The foam includes one or more of polyethylene foam, acrylic foam and polyurethane foam. If the foam is an acrylic foam, preferably the surface can be primed. When the surface of the acrylic foam is subjected to a primer treatment, its adhesion can be improved.

As the density of the foam increases, the breaking energy also increases and the tensile strength improves. On the other hand, the smaller the density of the foam, the greater the stretching force. Thus, the density of the foam in the buffer layer 134 is about 200g / cm ³ To about 700g / cm ^3, preferably from about 300g / cm ³ To about 600g / cm ^3, more preferably from about 400g / cm ³ To about 500 g / cm < ^{3 &} gt ;.

The thickness of the buffer layer 134 is about 100 탆 to about 500 탆, preferably about 200 탆 to about 400 탆, and more preferably about 200 탆 to about 350 탆. If the thickness of the buffer layer 134 is less than about 100 占 퐉, the additional buffering effect may be small. Further, when the thickness of the buffer layer 134 is more than about 500 mu m, the protective tape for marine 300 can be separated from the ship.

The protective tape for marine 300 according to the present invention includes the buffer layer 134 together with the base layer 150 including ultrahigh molecular weight polyethylene so that the protective tape 300 is applied to the marine vessel 10 and the surface of the marine vessel, The paint 20 can be protected.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims. Accordingly, the scope of protection of the present invention should be construed to cover not only the following claims, but also their equivalents.
