Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer panel for a refrigerator which is excellent in abrasion resistance and stain resistance, and which is suitable for small lot and various kinds of applications in which various printed patterns are provided. About. 2. Description of the Related Art In recent years, kitchens have been increasingly opened and designed to be designed next to a living room. As a result, the kitchen was often exposed to visitors. Refrigerators are relatively conspicuous and have a strong presence as home appliances used in kitchens. Although refrigerators are as prominent in living rooms as large furniture, it has been difficult until now to provide designs that meet individual needs. [0003] As a method of manufacturing a refrigerator outer panel having a multicolored pattern excellent in design, a printed film laminating method is generally employed. Further, as a method of manufacturing a small lot type design metal plate with a multicolor pattern, a masking coating method and a silk screen printing method are known. In a method of manufacturing a painted metal plate using a masking coating method or a silk screen printing method, a silk screen that has been subjected to a masking process or plate making is placed on a painted metal plate, and ink is stretched thereon to impart a design. Next, a clear coating made of urethane, acrylic, or the like is applied to protect the design surface. [0004] Since a design metal plate on which a print film is laminated has a large cost burden due to a plate cost, and it is difficult to laminate a metal plate cut into a predetermined size, a small size is required. It is difficult to cope with lots of various products. On the other hand, the manufacturing method of the printed metal plate using the masking coating method or the silk screen printing method requires a coating process for protecting the design surface after printing, so that both the printing process and the coating process are small. We have to deal with lot production. Therefore, it is more difficult for the process corresponding to a small lot to shorten the delivery time and reduce the cost compared to the printing process alone. In addition, when the coating process is reduced to a small lot, it becomes difficult to consolidate and improve the efficiency of the coating, so that it becomes difficult to implement environmental measures such as volatile organic compounds (VOC). Furthermore, if the painting process for protecting the design surface is omitted for the purpose of cost reduction and shortened delivery time, it becomes difficult to sufficiently secure the contamination resistance and wear resistance required for the refrigerator. The present invention has been devised in order to solve such a problem, and has excellent abrasion resistance and stain resistance even when various printed patterns are provided, and can be applied to small lot multi-product applications. It is intended to provide a skin for use. [0005] In order to achieve the object, a refrigerator outer panel of the present invention is provided with a transparent or translucent resin top coating layer, and the top coating layer has a thickness direction. Characterized in that it is formed using a printed metal plate provided with a colored pattern formed by a sublimable dye that has penetrated into the substrate. The “outer plate” of the present invention is a general term for the entire outer plate that is cut and bent and attached to the outer surface, upper surface, lower surface, and door surface of the refrigerator. In addition to the plates that make up the outer wall of the new refrigerator, it also includes a cover panel that is separately attached to give the exterior surface of the existing refrigerator a design. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A printing-coated metal plate using a sublimable dye is as follows.
It is manufactured by superimposing transfer paper printed by offset, silk, gravure, or the like on a metal coating surface and applying heat and pressure to make the sublimable dye penetrate into the top coating film. For example, for pattern printing using a sublimable dye, a method in which a transfer sheet is brought into contact with a coating film of a curable synthetic resin and heating is applied (Japanese Patent Application Laid-Open No. S51-24313). After forming a printing layer on a coated metal plate, a top coating film is formed on the surface, and then a heat treatment is performed to penetrate a sublimable dye from the inside of the coating film into the top coating film (JP-A-54-1979).
No. 104907), a method of penetrating a sublimable dye ink into a coating film of a prepainted metal plate on which a primer coating film and a colored coating film are formed (JP-A-7-31931), an opaque film provided on the surface of the metal plate. There is known a method of infiltrating a sublimable colorant into a resin layer (JP-A-7-102733). In the method of producing a multicolor pattern printing coated metal plate using these sublimable dyes, a post-coating step of protecting a transfer printing layer with a transparent resin after applying a design by thermal transfer is omitted. It becomes possible to manufacture a design metal sheet for a variety of lots at a relatively low cost and with a short delivery time. In addition, since a desired pattern can be provided only in a required amount when required, small-lot production of design metal sheets requiring various patterning is also easy from this point, and a short delivery time is possible. Become. A design metal plate manufactured by using a sublimable dye is not one in which ink is applied to the painted surface of the metal plate to develop the design, unlike screen printing, and a sublimation dye is coated on a metal plate. Since the design is expressed by penetrating the top coating film of the plate, an image can be directly applied to a coating film having excellent stain resistance. For example, JP
In Japanese Patent Application No. 01-158178, a design metal plate is manufactured by infiltrating a sublimable dye into a top coating film of a transparent or translucent resin containing a polyfluorocarbon chain-containing compound having excellent stain resistance and silicone oil. Such a top coating has almost no change in stain resistance even after being designed. Therefore, the design metal plate manufactured using the sublimable dye has sufficient stain resistance even when used in a kitchen where dirt of foodstuffs such as oil stains, soy sauce, and sauce is likely to adhere. Further, a design metal plate manufactured using a sublimable dye is one in which the sublimable dye is dyed almost uniformly in the thickness direction of the top coating film, and the sublimable dye is concentrated only in the surface layer. Therefore, print fading does not occur due to so-called "rubbing". Therefore, such a design metal plate has a sufficient abrasion resistance to withstand the wiping operation even if it is used for a refrigerator outer plate that requires frequent wiping of dirt. In Japanese Patent Application Laid-Open No. 2000-146422, a painted or surface-treated metal cover panel is put on the outside of an existing refrigerator to make the appearance fresh or new. That is, a side cover panel is covered on both sides of the refrigerator main body, and a main body top cover panel is covered on the upper surface of the main body, and is fixed with screws. The front and side surfaces of the door are covered with a front cover panel, the upper surface of the door is covered with a door upper surface cover panel, and the lower surface of the door is covered with a door lower surface cover panel, which is fixed with screws. Since all of these can be molded and covered without welding, a decorative metal plate manufactured using a sublimable dye can be molded and applied as a refrigerator cover panel. It goes without saying that not only the cover panel to be attached to the existing refrigerator, but also it can be molded into an appropriate shape and attached to the frame of a new refrigerator. Next, a method of manufacturing a design metal plate used as a material in the present invention will be described. As shown in FIG. 1, the printed painted metal plate as the material is a plated steel plate, a stainless steel plate,
A top coating layer 4 made of a transparent or translucent resin is formed on the surface of a base metal plate 1 such as an aluminum plate. As the base metal plate 1, as long as there is a transparent or translucent top coating layer 4 in the outermost layer, a coated metal plate (a) provided with a white base coat layer 2 and a coated metal plate (b) provided with a primer layer 3 ), A coated metal plate (c) provided with only a transparent or translucent top coating layer 4 without the base coat layer 2 or the primer layer 3 is used. When the base coat layer 2 that hides the color tone of the base metal plate 1 and the primer layer 3 is provided, a base coat layer having another color tone is not limited to white. The thickness of the base coat layer 2 is 10 to 20
It preferably has a dry film thickness of μm. 10 μm thick
When the base coat layer 2 is less than the above, the color tones of the base metal plate 1 and the primer layer 3 are not sufficiently covered. Conversely, 20 μm
In the base coat layer 2 having a thickness exceeding the above range, the solvent remaining in the coating film at the time of baking may be rapidly vaporized, and a pinhole-shaped coating defect called “side” may be generated. The material of the top coating layer 4 made of a transparent or translucent resin is not limited as long as it is a dyeable resin that accepts the sublimable dye transferred from the transfer sheet and dyes well. For example, vinyl resins such as polyvinyl alcohol, polyvinyl butyral, polyvinyl acetal, polyvinyl acetate, polyvinyl chloride, polyvinyl pyrrolidone, and polystyrene; and acrylate resins such as polymethyl (meth) acrylate, polybutyl (meth) acrylate, polyacrylamide, and polyacrylonitrile. resin,
Polysulfone resin, silicone polyester resin, etc.,
There are these copolymers or mixtures. Above all, it is preferable that the polyester resin is included as at least one component of the dyeable resin, since the polyester resin is well dyed by the sublimable dye and the storage stability of the obtained image is good. Further, the molecular weight of the dyeing resin is preferably 3000 or more in number average molecular weight. If the molecular weight is less than 3,000, the elongation characteristics of the coating film are insufficient, so that the possibility of cracking of the coating film increases. From the viewpoint of elongation characteristics of the coating film, the number average molecular weight of the dyeable resin is particularly preferably 10,000 or more. When a transfer sheet preliminarily patterned with a sublimable dye is brought into contact with the base metal plate 1 and heated, the sublimated dye penetrates into the transparent or translucent top coating layer 4 and is dyed in the thickness direction. A worn pattern is formed. The transfer sheet can be produced by gravure printing, offset printing, screen printing, or the like. In addition, for small lot printing, it can be produced by electrophotography, electrostatic recording, ink jet, thermal transfer, or the like which does not require a plate making process using computer graphics. Sublimable dyes are
A dye capable of transferring due to a phenomenon such as sublimation or volatilization when heated, and a disperse dye such as a quinophthalone derivative, an anthraquinone derivative, or an azo dye is preferably used. Further, those conventionally used for sublimation heat transfer, sublimation transfer printing, and the like can be used without particular limitation. The yellow sublimable dyes of this kind include:
Kayaset Yellow AG, Kayaset Yellow TDN (Nippon Kayaku Co., Ltd.), RTY52, Dianix Yellow 5R-E, Dian

(Sumitomo Chemical Co., Ltd.), MS Blue 50 (Mitsui Toatsu Dye Co., Ltd.), Ceres Blue GN (Bayer), Duranol Br
illiant Blue 2G (manufactured by ICI) and the like. The sublimable dyes for each color may be used alone or in combination of two or more. Black is obtained by appropriately mixing the sublimable dyes for yellow, magenta and cyan. As the sublimable dyes of colors other than yellow, magenta and cyan, those having a sublimation temperature (including the temperature of volatilization from a liquid material) of 60 ° C. or more are suitable. When a sublimable dye is selected, a dye having a high sublimation temperature is more preferable because it has a relatively high molecular weight and thus has excellent properties of light resistance and heat resistance. When the transfer sheet is heated while being in contact with the base metal plate 1, the sublimable dye contained in the transfer sheet sublimates, and as shown in FIG. In the thickness direction. Therefore, a three-dimensional printed pattern is exhibited by the transparent or translucent top coating layer dyed almost uniformly in the thickness direction. In this way, it is possible to easily provide a necessary pattern when necessary, and therefore, it is easy to produce a small lot of design metal plates requiring various patterns. In addition, it is not necessary to stock a design metal plate having a predetermined pattern, and a pattern can be formed according to needs. Further, since the dye layer does not exist alone between the top coating layer 4 made of a transparent or translucent resin and the base metal plate 1, delamination occurs as in a conventional laminated metal plate. Absent. The transparent or translucent top coating layer 4 is preferably made of a thermosetting resin which does not remarkably soften by heating at 150 to 200 ° C. during transfer. If such a resin system is selected, the gloss of the surface of the coated metal plate hardly decreases after the pattern is provided by thermal transfer. An ultraviolet absorber is added to the transparent or translucent top coating layer in order to prevent deterioration in adhesion and discoloration due to passage of sunlight or ultraviolet rays. As the ultraviolet absorber, a benzotriazole-based or triazine-based is used. Preferably, a triazine compound alone or a combination of a triazine compound and a benzotriazole compound is added. The ultraviolet absorber contained in the top coating film is required to have excellent heat resistance, sublimation resistance and solubility. From the viewpoint of heat resistance, those having a weight loss of 10% by weight or less at 300 ° C. under a heating condition of 5 ° C./min in an air atmosphere are preferred. As the benzotriazole-based ultraviolet absorber, octyl-3- [3-t-butyl-5- (2H-benzotriazol-2-yl)]-4-hydroxyphenyl] propinate (TINUVIN 384 manufactured by Ciba Geigy) ), 2- "2-hydroxy

It is preferable to adjust to 18 parts by weight. If the amount is less than 1% by weight, the light resistance of the sublimable dye permeated into the top coating layer tends to be insufficient. Conversely, if the amount exceeds 18 parts by weight, the stain resistance, workability, appearance of the coating film, etc., of the coating film deteriorate. In addition, coloring of the top coating film due to the ultraviolet absorber is also observed. In order to further improve the light resistance of the transparent or translucent top coating layer, a hindered amine-based light stabilizer may be blended, if necessary, in a proportion of 3 parts by weight or less based on 100 parts by weight of the nonvolatile matter of the paint. preferable. Examples of the hindered amine light stabilizer include the following. Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate (SANOL LS770 manufactured by Sankyo), bis

Even if the amount of the light stabilizer is more than 3.0 parts by weight, the effect of improving the light resistance is saturated, the improvement corresponding to the increase in the amount is not seen, and the appearance of the coating tends to deteriorate. The light stabilizer is preferably added in the range of 0.5 to 2.0 parts by weight. The transparent or translucent top coating layer 4 is applied via the base coat layer 2 (FIG. 1a), via the base coat layer 2 and the primer layer 3 (FIG. 1b), or directly on the base metal plate 1 (FIG. 1).
c) can be formed. In any case, the color tone of the base metal plate 1 and the base coat layer 2 becomes a ground pattern, and a printed metal plate having a unique depth feeling utilizing the texture of the base material can be obtained. Since this printed painted metal plate is excellent in workability, it is formed into a shape corresponding to the application area of the refrigerator by an appropriate method and attached. EXAMPLE 1 Production of Painted Metal Sheet Used as Base Metal Sheet A 0.8 mm thick Zn-plated steel sheet was subjected to a pre-painting treatment.
White polyester resin paint (Kansai Paint Co., Ltd.)
AT-1001 primer) was applied to a dry film thickness of 18 μm, and baked at a plate temperature of 220 ° C. for 1 minute to form a white base coat resin film layer. Next, a triazine-based UV absorber (TIVA Geigy
NUVIN 400) and a polyester clear resin paint (AT-1005 manufactured by Kansai Paint Co., Ltd.) containing 6 parts by weight and 1.5 parts by weight of a hindered amine light stabilizer (TINUVIN 123 manufactured by Ciba Geigy Co., Ltd.) based on 100 parts by weight of the nonvolatile matter of the coating.
Primer) is applied to a dry film thickness of 15 μm, and baked at a plate temperature of 210 ° C. for 1 minute.
A transparent top coating layer was formed. Transfer of a Pattern Using a Sublimable Dye Using a sublimable dye toner (a sublimation printing toner manufactured by Nippon Steel Chemical Co., Ltd.), an electrostatic recording system image printing system (Jana manufactured by Exis Co., Ltd.) is used. A cyan solid pattern was output on recording paper. The obtained electrostatic recording paper was superimposed on the painted surface of the coated steel sheet, and the temperature was 165 ° C. and the pressure was 0.5 k.
The thermocompression bonding was performed for 150 seconds at g / cm ² . After the completion of the pressure bonding, the electrostatic recording paper was peeled off from the coated steel sheet. Example 2 Production of Painted Stainless Steel Sheet Used as Base Metal Sheet A stainless steel sheet (SUS304HL) having a thickness of 0.8 mm was subjected to a pre-coating treatment, and a triazine-based ultraviolet absorber (TINUVIN 400 manufactured by Ciba Geigy) was applied to paint non-volatile. A polyester clear resin paint (AT-1005 primer manufactured by Kansai Paint Co., Ltd.) containing 6 parts by weight and 1.5 parts by weight of a hindered amine light stabilizer (TINUVIN 123 manufactured by Ciba Geigy) per 100 parts by weight of the dried coating film 15 μm
Then, the coating was baked at a plate temperature of 210 ° C. for 1 minute to form a transparent top coating layer. Transfer of Pattern Using Sublimable Dye The same sublimable dye was used as in Example 1 and the pattern was transferred to a coated stainless steel plate in the same manner. The printed metal plates for refrigerator outer panels manufactured in the above steps were examined for stain resistance, wear resistance and workability. Table 1 shows the survey results. In addition, each characteristic was evaluated by the following test methods. The stain resistance test coated surface to draw a red line and a black line in the oil-based ink, after standing for 24 hours in 20 ° C., the red line and wipe the black line with methanol, what is no trace 5, traces slightly The remaining ones were evaluated as 3 and those with remarkable traces as 1, and evaluated on a 5-point scale. In addition, if it is three or more points about the red line drawn with oil-based ink, it can be practically used as a printed metal plate for refrigerator outer panels. Abrasion test A hole having a diameter of 6 mm was made at the center of a test piece having a diameter of 120 mm.
After measuring the weight of the test piece, it was attached to a Taber tester. After rotating the test piece 200 times, the weight was measured.
The amount of wear was determined from the weight difference before and after the test, and the Taber index was calculated according to the following equation. In addition, CS-10 is used for worn wheels.
Was measured according to JIS A1453.
When the Taber index is 80 or less, it can be practically used as a printed painted metal plate for a refrigerator outer panel. Taber index = wear loss (mg) × 1000 / rotational speed (200) Further, the reflection density before and after the wear resistance test was measured using a reflection density meter RD-1200 manufactured by Macbeth. If the difference between the reflection densities before and after the abrasion resistance test is 0.5 or less, it can be practically used as a printed metal plate for refrigerator outer panels. Workability test The workability was determined by performing 180 ° bending at 0 to 6 t (1 t when one plate having the same thickness as the test piece was sandwiched) in a room at 20 ° C. Observed. The evaluation was made by investigating the occurrence of cracks in the coating film according to the degree of bending. 0
When no crack was detected in the coating film at ~ 2t,
The workability was evaluated as ○ when cracks occurred in the coating film at 3 to 4 t, Δ when cracks occurred at 5 t, and × when cracks occurred at 6 t. Usually, if the evaluation point is ○ or more, it can be practically used as a printed painted metal plate for a refrigerator outer panel. [0032] As can be seen from the investigation results in Table 1, all of the printed coated metal sheets of the present invention can be sufficiently used as refrigerator outer panels in all respects of stain resistance, abrasion resistance and workability. Had properties. In addition, the print painting appearance,
Because there is no adhesion of oil-based ink and excellent stain resistance,
Good appearance over a long period of time. As an evaluation of the abrasion resistance, the difference in the reflection density of cyan before and after the Taber test was also measured. However, a large change in color tone which was a problem in practical use was not observed. As described above, the refrigerator outer panel of the present invention has a desired pattern by infiltrating a sublimable dye in the thickness direction into a top coating layer made of a transparent or translucent resin. Is formed. Therefore, even after the pattern is provided, the original characteristics of the top coating layer can be maintained for a long period of time, and the stain resistance and abrasion resistance required for the refrigerator can be secured. Since it has excellent workability, it can be formed into a shape according to the application location. Further, patterning can be easily performed by a transfer printing method using a sublimable dye. Therefore, it is possible to manufacture a refrigerator outer panel most suitable for small lot multi-product use with high productivity.
