Brief Description of the Drawings
[13] The above and other objects, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention in conjunction with the accompanying drawings, in which:
[14] FIG.1 is an exploded perspective view of a portion of a metal laminating steel sheet according to an embodiment of the present invention,
[15] FIG. 2 is a cross-sectional view of the metal laminating steel sheet shown in FIG. 1, and
[16] FIG. 3 is a process diagram for explaining a method of manufacturing a metal laminating steel sheet according to the embodiment of the present invention. Best Mode for Carrying Out the Invention
[17] Hereinafter, the metal laminating steel sheet and the method of manufacturing the same will be described in detail in connection with the appending drawings.
[18] FIG. 1 to FIG. 3 show the metal laminating steel sheet and the method of manufacturing the same according to the present invention, in which FIG. 1 is an exploded perspective view of a portion of a metal laminating steel sheet according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the metal laminating steel sheet shown in FIG. 1, and FIG. 3 is a process diagram for explaining a method of manufacturing a metal laminating steel sheet according to the embodiment of the present invention.
[19] As shown in the drawings, the metal laminating steel sheet according to the embodiment of the present invention, comprises a base material 10, a coating layer 20, an adhesive layer 30, and a metal surface material 40.
[20] The base material comprises a general iron plate. Especially, the base material 10 is preferably any one selected from a hot-dip galvanized steel sheet, an electro- galvanized steel sheet, a cold rolled steel sheet and an aluminum plate.
[21] In addition, the base material 10 is available from the surrounding store. Whichever base material is purchasable at low cost is sufficient.
[22] The coating layer 20 is formed on a top surface of the base material 10 by being subjected to a chemical conversion treatment.
[23] The adhesive layer 30 is formed on the chemical synthetic treated coating layer 20, and is a thermosetting adhesive consisted essentially of acryl, urethane, and phenol resin in the present embodiment.
[24] The metal surface material 40 is attached on a surface of the adhesive layer 30, and is any one selected from a stainless steel sheet, a copper plate and an aluminum plate.
[25] This is because the stainless steel sheet, the copper plate, or the aluminum plate is
expensive and used widely in the field of construction and industry.
[26] Hereinafter, the method of manufacturing the metal laminating steel sheet according to the embodiment of the present invention will be described.
[27] First, a base material 10, which is selected from a hot-dip galvanized steel sheet, an electro-galvanized steel sheet, a cold rolled steel sheet and an aluminum plate, is prepared (Sl; base material providing step).
[28] Then, surfaces of the base material 10 and the metal surface material 40 are degreased, boiling water rinsed, or rinsed by using a general degreasing agent consisting essentially of alkali surfactant (S2; cleansing step).
[29] Next, the coating layer 20 is formed on the surface of the base material 10 by performing a chemical conversion treatment (S3: coating layer forming step).
[30] The chemical conversion treatment can be performed through a known process, in particular, it can use a phosphate coating treatment, and a chromate treatment, and the like.
[31] The chemical conversion treatment can improve the adhesive force and corrosion resistance of the base material 10 and the metal surface material 40.
[32] Next, the adhesive layer 30 is formed on the surface of the coating layer 20 obtained through the surface treatment (S4: adhesive layer forming step).
[33] The adhesive layer formation step S4 is performed by applying a thermo- setting adhesive essentially consisting of acryl, urethane and phenol resin to the coating layer, and baking the resultant adhesive at 2000C to 3000C for one to three minutes under atmospheric pressure to thereby cure the thermo-setting adhesive.
[34] Next, the metal surface material 40 is attached on the surface of the adhesive layer
30 (S5; surface material attaching step).
[35] The hot-dip galvanized steel sheet, the electro-galvanized steel sheet, the cold rolled steel sheet, or the aluminum plate can be used for the metal surface material 40, as previously described.
[36] The metal laminating steel sheet obtained through the above processes can be used for substituting applications of the existing expensive stainless steel sheet, the copper plate, or the aluminum plate, and the like, because it is excellent in machinability and surface physical property.
[37] The metal laminating steel sheet of the present invention is excellent in machinability because the stainless steel sheet, which is attached on the base material 10, cannot be separated due to its good adhesive force even if it is scratched by a knife or performed of some working, and the entire base material 10 can maintain the special property of the stainless steel sheet by maintaining the special property such as luster, excellent in a sense of beauty, and rust-proof property. Accordingly, it is possible to provide a steel sheet displaying special properties identical to those of the stainless
steel sheet with a cost, which is very low in comparison with that for manufacturing an expensive stainless steel sheet into a thick thickness.
Mode for the Invention [38] Hereinafter, the present invention will be described in relation to more concrete embodiment thereof. [39] Embodiment
[40] The surface of a hot-dip galvanized iron plate is treated by chemicals (SC#155; produced from Ipsi chemicals), which is consisted essentially of alkali surfactant. [41] Then, a surface treated coating layer is formed on the resultant base material by using a phosphate consisting of chemical synthetic treating agent (NRC #300; Ipsi chemicals). [42] A thermosetting adhesive (SC611; Sony Company) is applied on the resultant surface treated coating layer, and it is baked for ninety seconds in a baking furnace at
27O0C to thereby form an adhesive layer. [43] Then, a stainless steel sheet is attached on the adhesive layer as a metal surface material layer, and then water cooled to thereby manufacture the metal laminating steel sheet. [44] The product physical properties of the obtained metal laminating steel sheet are as follows.

[2] The metal laminating steel sheet according to claim 1, wherein the adhesive layer comprises a thermosetting adhesive consisting essentially of acryl, urethane and phenol resin, and the metal surface material is any one selected from a stainless steel sheet, a copper plate and an aluminum plate.
[3] A method of manufacturing a metal laminating steel sheet, comprising the steps of:
(a) providing a base material;
(b) forming a coating layer on a surface of the base material, the coating layer being subjected to a chemical conversion treatment;
(c) forming an adhesive layer on a top surface of the coating layer, which is formed in the previous step (b); and
(d) attaching a metal surface material to a top surface of the adhesive layer.
[4] The method according to claim 3, further comprising a step of cleansing the surfaces of the base material and the metal surface material by means of a degreasing, a boiling water rinsing, and a rinsing with a general degreasing agent essentially consisting of alkali surfactant, after performing the step (a).
[5] The method according to claim 4, wherein the step of forming the adhesive layer is carried out by applying a thermosetting adhesive consisting essentially of acryl, urethane, and phenol resin to the top surface of the coating layer, and then baking the applied thermosetting adhesive for one to three minutes under atmospheric pressure at 2000C to 3000C to thereby cure the thermosetting adhesive.
