Description

Technical Field [0001] The present invention relates to a multi-layer film applied to a ship,

The present invention relates to a multilayer film attached to a ship.

Generally, the appearance of a ship is composed of steel plates, which are susceptible to corrosion by high salinity seawater. Therefore, paint is applied to prevent corrosion of the steel sheet when the ship is dried.

Since the ship is kept exposed to seawater and sea breeze, special paint is used to paint, and the thickness of the paint is also large. The ship painting is done by coating the steel plate several times, which requires a lot of time and cost to paint the ship.

In order to compensate for this, a method of attaching a film to a ship is used instead of a paint. The film consists of an adhesive layer and a coating layer, in which the adhesive layer is attached to the surface of the vessel and the coating layer protects the vessel from the outside.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

1 is a view showing a ship to which a multilayer film according to an embodiment of the present invention is attached.

In order to protect the surface of the ship 100, the surface thereof is generally painted, but a film attaching method can be used in consideration of the time and cost required for painting the ship.

Referring to FIG. 1, the film 200 may be attached to the surface of the ship 100 with a predetermined width. FIG. 1 shows the film 200 attached in the transverse direction.

On the other hand, the film 200 can be attached to various parts of the ship 100 as well as the outer surface of the ship 100. In general, painting is performed to prevent corrosion of a target object, and the film 200 can be attached to any part for preventing corrosion. For example, the film 200 may be attached to the outdoor exposure zone such as the deck and the outer wall of the residence, and the film 200 may be attached to the room.

As described above, the regions to which the film 200 is attached are spaces that perform their own functions, and the outermost film layer exposed to the outside is also preferably changed depending on its function. For example, as the outermost film layer, it is preferable to use a material having high weather resistance in the case of an outdoor exposure zone, and a material having high rust prevention property in the case of a seawater flooding zone is preferably used. Is preferably used.

For example, polyurethane and polysiloxane are used as materials having high weather resistance, and anti-corrosive epoxy paint is used as a material having high rust resistance. As a material having a high antifouling property, Anti-fouling paints such as self-polishing polystyrene (SPC) or silicone paints may be used.

It is preferable that a film suited to the function of each zone be separately provided and attached to the corresponding zone, but in such a case, the utilization of the film may be restricted. That is, a film used in the outdoor exposure zone can not be used to prevent corrosion of the seawater submergence zone, and a separate film must be provided for the seawater submergence zone. In other words, when a film attached to a section of a seawater immersion area is newly replaced, even if there is a spare portion of the film used in the outdoor exposure section, it can not be used.

Thus, unnecessary expense may occur if the utilization of the film is limited. It is necessary to purchase an unnecessarily large number of films in order to replace the film of a section of the seawater immersion area.

Therefore, the film according to the embodiment of the present invention may be attached only to an object existing on the inside or outside of the ship, and the functional film layer providing the function according to the zone may be separately attached to the outermost layer.

It is possible to attach the basic film for attachment to the object and attach the functional film layer only to the outermost periphery, thereby reducing the cost for attaching the film. For example, since only a basic film is adhered to the inside and the outside of a ship, the functional film layer is attached to each space, so that it is not necessary to separately provide a space-specific film. Further, when it is desired to replace a film of a certain section of a specific zone, only the functional film layer can be replaced. In addition, if the area does not require special functions, it may be possible to finish the film attaching operation by attaching only the basic film.

Hereinafter, a film to which a separate functional film layer is attached while performing a role of attaching to an object is referred to as a multilayer film.

On the other hand, the functional film layer is directly adhered to the basic film without a separate adhesive material or adhesive film layer. Since the functional film layers that provide different functions have different compositional structures, the efficiency of adhesion with the multi- have. For example, in the case of a specific functional film layer, it is easily adhered to a basic film, but in the case of another functional film layer, it may not be adhered to a multilayer film.

Thus, in the multilayer film according to the embodiment of the present invention, different functional film layers can be attached with high adhesive efficiency. That is, the adhesive function in response to the component of each functional film layer is expressed on the contact surface contacting the functional film layer, thereby improving the adhesion efficiency with the functional film layer.

To this end, the multi-layer film may include a multi-functional film layer for improving the adhesion efficiency with the functional film layer, as well as an adhesive film layer for adhesion with the object.

2 is a view showing a multilayer film according to an embodiment of the present invention.

Referring to FIG. 2, the multilayered film 200 includes a first film layer 210, a second film layer 220, and a multifunctional film layer 230.

The first film layer 210 includes a first side and a second side to provide corrosion protection against the marine surface. To this end, the first film layer 210 may prevent the surface of the ship from being exposed to the outside. That is, the first film layer 210 may be referred to as a coating layer. For example, the first film layer 210 may include a coating material, which prevents corrosion of the surface of the ship by preventing the coating material from contacting the outside with the surface of the ship.

The second film layer 220 serves to fix the first film layer 210 to the surface of the ship. That is, the second film layer 220 may be an adhesive layer. For example, the second film layer 220 may be composed of an adhesive, one side of which is attached to one side of the first film layer 210, and the other side of which is attached to the surface of the vessel.

2 illustrates that the second film layer 220 is formed on one side of the first film layer 210 but only a part of one side of the first film layer 210 includes the second film layer 220 May be formed.

The multifunctional film layer 230 functions to fix the functional film layer to the multilayer film 200, preferably, the first film layer 210 by developing an adhesive function to the functional film layer to be attached. To this end, the multifunctional film layer 230 may include one or more adhesive components that exhibit an adhesive function depending on the functional film layer to be attached.

FIG. 3 is a view showing that the function of the multifunctional film layer according to an embodiment of the present invention is divided.

In the case where a separate functional film layer is not attached, at least one adhesive component maintains a state in which the adhesive function is not expressed, and when a specific functional film layer is attached, adhesion of the adhesive component corresponding to the functional film layer Function is developed to adhere the functional film layer.

When the functional film layer is adhered, the adhesive component corresponding to the attached functional film layer among the adhesive components contained in the multifunctional film layer 230 may form an adhesive layer. The first adhesive component 310 moves to one side of the upper surface of the multifunctional film layer 230 so that the upper layer 231 forms a first adhesive layer and the second adhesive component 320 is bonded to the multifunctional film layer 230. [ And the lower layer 232 forms the second adhesive layer.

For example, the functional film layer comprises a film layer that provides at least one of the aforementioned weathering, rust-inhibiting and antifouling properties. That is, each of functional film layers that provide weatherability, rust prevention or antifouling property may be present. In addition, the first film layer 210 that provides the corrosion protection function is also included in the functional film layer.

Referring to FIG. 3, the multifunctional film layer 230 may include a first adhesive component 310 performing a first adhesive function and a second adhesive component 320 performing a second adhesive function. The first adhesive component 310 and the second adhesive component 320 are contained in the multifunctional film layer 230 without boundaries. Further, in the case where the functional film layer is not attached, the adhesive function of the first adhesive component 310 and the second adhesive component 320 is not expressed. When the specific functional film layer is adhered while maintaining this state, the corresponding adhesive function of the first adhesive component 310 or the second adhesive component 320 is expressed. For example, if the component of the functional film layer is reactive with the first adhesive component 310, the first adhesive component 310 moves toward the functional film layer to form the first functional layer, The second adhesive component 320 moves toward the functional film layer to form the second functional layer.

In addition, the first adhesive component 310 or the second adhesive component 320 may not react only with the functional film layer constituted by a specific component but may react with the functional film layer of various components. For example, the first adhesive component 310 exhibits an adhesive function in response to the functional film layer of a high weather-resistant component and a high-rust component, and the second adhesive component 320 is a component having high rust- And the adhesive function can be expressed in response to the functional film layer of the corrosion-type component.

Referring again to FIG. 2, the multifunctional film layer 230 is attached to one side of the first film layer 210. In this case, as the first film layer 210 is attached to one side of the multifunctional film layer 230, the adhesive component included in the multifunctional film layer 230 reacts with the components of the first film layer 210 to perform an adhesive function And can perform rigid bonding with the first film layer 210.

4 is a cross-sectional view of a multilayer film layer according to one embodiment of the invention.

Referring to FIG. 4, one surface of the first film layer 210 and one surface of the multifunctional film layer 230 are bonded. As described above, since the first film layer 210 is also a kind of functional film layer, the adhesive component contained in the multifunctional film layer 230 can be reacted with the components of the first film layer 210. Thus, the lower layer 232 of the multifunctional film layer 230 becomes able to form an adhesive layer.

On the other hand, since the functional film layer is not attached on the upper surface of the multifunctional film layer 230, the adhesive layer is not formed in the upper layer 231.

FIG. 5 is a view showing that a functional film layer is attached to a multilayer film layer according to an embodiment of the present invention.

5, the upper layer 231 of the multifunctional film layer 230 is converted into an adhesive layer as the functional film layer 240 is attached to the upper surface of the multifunctional film layer 230. That is, the upper layer 231 of the multifunctional film layer 230 serves as an adhesive layer for bonding with the functional film layer 240, and the lower layer 232 of the multifunctional film layer 230 serves as a first film layer 210 ) As a bonding layer for bonding with the substrate.

By attaching the multifunctional film layer 230 to the marine surface as the multifunctional film layer 230 is firmly bonded to the film layers attached to both sides thereof and then attaching the functional film layer 240 without any additional bonding material The film attaching operation for the corresponding area can be completed.

6, another functional film layer (hereinafter, referred to as " functional film layer ") may be provided on the functional film layer 240 (hereinafter referred to as the first functional film layer) 240 attached to the multi- (Hereinafter referred to as a second functional film layer) 250 may be attached. Here, the cohesive force may not be generated between the first functional film layer 240 and the second functional film layer 250, and an adhesive material or an adhesive layer may be formed between the first functional film layer 240 and the second functional film layer 250, (Not shown).

7 is a diagram illustrating the attachment of a non-functional film layer to a multilayer film layer according to an embodiment of the present invention.

The adhesive component contained in the multifunctional film layer 230 according to the embodiment of the present invention may exhibit an adhesive function in response to only the specific functional film layer. Therefore, when a film layer composed of a component that does not react with the adhesive component is adhered, the adhesive function may not be developed. Hereinafter, the film layer which does not exhibit the adhesive function is referred to as a non-functional film layer.

Referring to FIG. 7, it is shown that the adhesive component of the multifunctional film layer 230 does not exhibit an adhesive function as the non-functional film layer 260 is attached. The lower layer 232 of the multifunctional film layer 230 is formed with an adhesive layer for bonding with the first film layer 210 while the upper layer 231 of the multifunctional film layer 230 is bonded to the non- ), The adhesive layer is not formed.

When the adhesive layer is not formed on the multifunctional film layer 230, bonding with the non-functional film layer 260 is not robust. Thus, once the non-functional film layer 260 is attached, it becomes easy to remove it.

8 is a view showing that the non-functional film layer of Fig. 7 is removed from the multi-functional film layer.

Referring to FIG. 8, the non-functional film layer 260 attached to the multi-functional film layer 230 is removed. For example, after attaching the multi-layer film 200 to the surface of the vessel, the non-functional film layer 260 may be attached to the multi-functional film layer 230 to protect it, The non-functional film layer 260 may be removed to adhere the film layer 240.

9 is a view showing that a functional film layer is attached to a multifunctional film layer from which the non-functional film layer of FIG. 8 is removed.

Since the multifunctional film layer 230 and the non-functional film layer 260 are not bonded with a large cohesive force, even if the non-functional film layer 260 is removed, the corresponding surface of the multifunctional film layer 230 can be maintained in its original state do.

Thus, it is possible to attach the functional film layer 240 after removing the non-functional film layer 260 from the upper layer 231 of the multi-functional film layer 230 as shown in FIG. When the functional film layer 240 is attached, the adhesive component contained in the upper layer 231 of the multifunctional film layer 230 reacts with the functional film layer 240 to form an adhesive layer.

Although the above description has been made mainly on the provision of the functional film layer in the form of a film, the functional film layer may be provided in a coating manner. For example, one or more paints may be applied to the upper surface of the multifunctional film layer 230 to provide at least one of weather resistance, rust resistance and antifouling properties.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
