Description

  The present invention relates to a decorative article obtained by lacquering a metal substrate, a jewelry and a wristwatch including the decorative article, and a method for manufacturing the decorative article.

In recent years, some accessories such as watches, necklaces, brooches, earrings, and the like are provided with a decorative article in which lacquer is coated on the surface of a metal base material made of a metal material as disclosed in Patent Document 1, for example. In general, in this type of coating, a lacquer is applied to a metal substrate, and then baked and dried at a temperature of 100 ° C. or higher to cure the lacquer film in a short time.
Japanese Unexamined Patent Publication No. 2000-141995

By the way, even if lacquer is baked and painted on the surface of a metal substrate, the phenomenon that the lacquer film peels off from the surface of the metal substrate due to the difference in thermal expansion coefficient between the metal substrate and the lacquer film is likely to occur. There is a problem that a beautiful appearance as a product cannot be maintained for many years.
Conventionally, in order to suppress this peeling, for example, as in Patent Document 1, when the surface of the metal substrate is subjected to undercoating and intermediate coating lacquer processing, the undercoating lacquer film is made of the same material or the same level as the metal substrate. By mixing specific gravity metal powder, the adhesion between the metal substrate and the lacquer film is improved.
However, there is a problem that the adhesion strength between the metal substrate and the lacquer film is still insufficient only by mixing metal powder into the lacquer film, and peeling of the lacquer film cannot be prevented for many years. This problem is particularly likely to occur when the metal substrate is made of a relatively soft metal such as gold, brass, or bronze.

  This invention was made in view of the above-mentioned circumstances, and while maintaining the lacquer characteristics such as robustness and beauty of appearance while preventing the peeling of the lacquer film from the metal base material, it is possible to maintain for many years. It is an object of the present invention to provide a decorative product, a jewelry and a wristwatch including the decorative product, and a method for manufacturing the decorative product.

The first lacquer film 51, the second lacquer film 52, the third lacquer film 53, and the two decorative lacquer films 54 and 55 are formed to have substantially the same thickness. In addition, the surface 55 a of the decorative lacquer film 55 located at the top is formed so as to be smoothly connected to the surface 41 a of the metal substrate 41.
The purified lacquer used as the decorative lacquer films 54 and 55 includes, for example, black lacquer and translucent lacquer, but may be colored lacquer obtained by mixing a pigment with translucent lacquer, for example. Moreover, this refined lacquer may be glossy or may be glossless.

Further, the lacquer film laminate 43 includes a large number of dry lacquer particles 56 embedded in three lacquer films of the first lacquer film 51, the second lacquer film 52, and the third lacquer film 53.
Each dry lacquer particle 56 is formed by mixing black lacquer with kaolin and iron oxide in the form of particles, and the particle diameters of the first lacquer film 51, the second lacquer film 52 and the third lacquer film 53 are the same. It is larger than the thickness dimension of each lacquer film and smaller than the combined thickness dimension of these three lacquer films 51, 52, 53. Thereby, each dry lacquer particle 56 can be contacted with three lacquer films of the 1st lacquer film 51, the 2nd lacquer film 52, and the 3rd lacquer film 53, and also in these 3 lacquer films 51, 52, and 53 Can be buried.

When manufacturing the dry lacquer particles 56, first, a mixed lacquer solution obtained by mixing black lacquer with powdered kaolin and iron oxide is coated on a glass plate in a film form. Here, the mixed lacquer liquid is preferably mixed in a weight ratio of 40% to 98% black lacquer, 1% to 30% kaolin, and 1% to 30% iron oxide. Next, the mixed lacquer solution is dried to form a dry lacquer film. Finally, the dry lacquer film is scraped off from the glass plate and pulverized into a powder to obtain a large number of dry lacquer particles.
Thus, the dry lacquer particle 56 which contains all of black lacquer, kaolin, and iron oxide can be obtained by manufacturing the dry lacquer particle 56. FIG.

  The trunk 9, the back cover body 15, the dial 21, and the crown 33 made of decorative items are configured in the same manner as the decorative member 37 described above. That is, the lacquer film laminate 43 is formed on each surface of the trunk 9, the back cover body 15, the dial 21, and the crown 33 that can be seen from the outside. In addition, the formation position of this lacquer-film laminated body 43 is not restricted to the position (hatched position) of the example of illustration, It can change suitably according to the design of the wristwatch 1.

Next, the manufacturing method of the decorative article which comprises this trunk | drum 9, the back cover main body 15, the dial 21, and the crown 33, and the decoration member 37 of the rotor 8 is described.
When manufacturing the decorative article and the decorative member 37, first, the first lacquer film 51 is formed by coating raw lacquer on the bottom surface 45a of the recess 45 formed on the surface 41a of the metal base material 41 in a film shape ( First coating process), a large number of dry lacquer particles 56 containing kaolin and iron oxide in black lacquer (spreading process). Since the first lacquer film 51 is not dried in this spreading step, a part of each dry lacquer particle 56 is buried inside the first lacquer film 51.
After the spreading step, the first lacquer film 51 is baked and dried (baking and drying step). In this case, a large number of dry lacquer particles 56 are fixed to the first lacquer film 51, and the adhesion of the first lacquer film 51 to the bottom surface 45 a of the recess 45 can be improved by the large number of dry lacquer particles.

  Next, a second lacquer film 52 is formed on the first lacquer film 51 by coating a paint obtained by mixing bengara with raw lacquer, and the second lacquer film 52 is baked and dried (second coating process). The coating in the second coating process is performed such that a part of each dry lacquer particle 56 protrudes from the surface of the second lacquer film 52. Furthermore, raw lacquer is coated on the second lacquer film 52 to form a third lacquer film 53, and the third lacquer film 53 is baked and dried (third coating step). The coating in the third coating step is performed so that each dry lacquer particle 56 is buried.

After completion of the third coating process, the decorative lacquer film 54, 55 is formed by coating purified lacquer on the third lacquer film 53, and the decorative lacquer film 54, 55 is baked and dried twice. In this decorative coating process, baking and drying are performed each time the decorative lacquer films 54 and 55 are coated.
In the baking drying process, the second coating process, the third coating process, and the decorative coating process, it is preferable to heat the coated lacquer film to 100 ° C. or more and 300 ° C. or less.
After completion of the decorative coating process, the lacquer is coated on the decorative lacquer film 55 and wiped off so that the raw lacquer is rubbed (sliding lacquer process). This sliding lacquer process may be performed only once or may be repeated a plurality of times. By carrying out this sliding lacquer process, the decorative lacquer film 55 can be protected by the raw lacquer rubbed.

  As described above, according to the decorative article and the decorative member 37 included in the wristwatch 1 according to this embodiment, a large number of dry lacquer particles are arranged by arranging each dry lacquer particle 56 so as to cover the three lacquer films 51, 52, 53. Since 56 reduces the hardness in the surface direction in each lacquer film 51, 52, 53, the stretchability in the surface direction of the three lacquer films 51, 52, 53 can be improved, and the three lacquer films 51 , 52, 53 can follow the deformation of the metal base 41. That is, even if the metal substrate 41 is deformed, the three lacquer films 51, 52, 53 including the dry lacquer particles 56 absorb the stress generated between the first lacquer film 51 and the metal substrate 41, It is possible to prevent the films 51, 52, and 53 from peeling from the metal base material 41.

Moreover, even if a strong external force such as an impact is applied in the thickness direction of the three lacquer films 51, 52, 53 by making the structure in which the dry lacquer particles 56 are arranged over the three lacquer films 51, 52, 53, scratches It is also possible to prevent deformation such as shaving and depression. Therefore, the robustness and beauty that are the characteristics of lacquer can be maintained for many years.
Since the dry lacquer particles 56 contain kaolin with good absorbency of lacquer, the above effects are easy to get familiar with the three lacquer films 51, 52, 53 through the dry lacquer particles 56, and the three lacquer films 51, 52, This is due to the fact that the adhesion to 53 and the dry lacquer particles 56 also contain iron oxide, and therefore the adhesion between the metal substrate 41 and the first lacquer film 51 is improved.

Moreover, the particle diameter of the dry lacquer particle 56 is larger than the thickness dimension of each lacquer film of the first lacquer film 51, the second lacquer film 52, and the third lacquer film 53, and these three lacquer films 51, 52, 53 Is set to be smaller than the combined thickness dimension, so that the dry lacquer particles 56 are prevented from being exposed outward from the surface of the third lacquer film 53, and the surface of the third lacquer film 53 is flattened. The surface 55a of the film stack 43 can be easily flattened.
Furthermore, by forming the decorative lacquer films 54 and 55 on the third lacquer film 53, the surface of the decorative article 37 and the decorative member 37 subjected to lacquer processing can be surely flattened, and the glossy beautiful appearance can be obtained. The decorative article and the decorative member 37 which have can be provided.
Further, by providing the lacquer film laminate 43 in the recess 45 of the metal base material 41, the metal base material 41 and the surfaces 41a and 55a of the lacquer film laminate 43 can be smoothly connected. Moreover, in the case of manufacture, the lacquer decoration part with respect to the metal base material 41 can be prescribed | regulated previously, and lacquering can be performed easily.

And according to the manufacturing method of the ornament and the decorative member 37 of this embodiment, since the three lacquer films 51, 52, and 53 are each coated so as to come into contact with each dry lacquer particle 56, the dry lacquer particle 56 is reliably attached. Can be adapted to each lacquer film 51, 52, 53.
Furthermore, by including Bengala in the second lacquer film 52, a portion of the raw lacquer that forms the third lacquer film 53 penetrates the second lacquer film 52 in the third coating step. The adhesion of the lacquer film 53 can be improved.

Further, by performing the decorative coating process, it is possible to flatten the surface of the decorative article and the decorative member 37 made of the decorative lacquer films 54 and 55, thereby providing the decorative article and the decorative member 37 having a glossy and beautiful appearance. In particular, by performing this decorative coating process a plurality of times, the surface of the decorative article and the decorative member 37 can be reliably formed flat.
Furthermore, in baking drying, in order to heat the coated lacquer films 51 to 55 to 100 ° C. or more and 300 ° C. or less, the monomolecular urushiol contained in each lacquer film 51 to 55 is reliably polymerized in a short time. Therefore, it is possible to reliably prevent the skin from being rashed by urushiol when the wristwatch 1 is worn.

  In the above-described embodiment, the rotor 8 is configured by fixing the decoration member 37 to the rotor body 35. For example, the rotor body 35 is integrally formed of the same metal material as the metal base material of the decoration member 37. The lacquer film laminate 43 may be directly formed on the rotor body 35 and configured. However, since the rotor 8 is arranged close to the movement 7, it is more preferable that the rotor 8 is manufactured by being divided into the rotor body 35 and the decorative member 37 so that the rotor 8 is not warped during lacquer processing. .

In addition, although the two decorative lacquer films 54 and 55 of the lacquer film laminate 43 are stacked, for example, only one may be formed, or three or more may be stacked.
Furthermore, the lacquer film laminated body 43 should just be equipped with the 1st lacquer film 51, the 2nd lacquer film 52, the 3rd lacquer film 53, and many dry lacquer particles 56 at least. That is, for example, when the design uses the color of Bengala contained in the dry lacquer particles 56 or the second lacquer film 52, transparent lacquer may be used as the decorative lacquer films 54 and 55, but the third lacquer film 53 The decorative lacquer films 54 and 55 do not have to be formed thereon. In addition, when the 3rd lacquer film 53 becomes the uppermost lacquer film of the lacquer film laminated body 43, it is preferable that the surface of this 3rd lacquer film 53 continues smoothly to the surface 41a of the metal base material 41.
Moreover, although the lacquer film laminated body 43 was formed in the recessed part 45 formed recessed from the surface 41a of the metal base material 41, it is not restricted to this, For example, it is directly on the surface 41a of the metal base material 41 It may be formed.

Furthermore, the particle diameter of each dry lacquer particle 56 is not limited to that set in the above embodiment, and at least each dry lacquer particle 56 is composed of the first lacquer film 51, the second lacquer film 52, and the third lacquer film 53. It only needs to be in contact with two lacquer films.
Further, the metal base 41 may be made of a metal material (for example, iron or stainless steel) that is harder than dry lacquer, but the above-described effects are similar to gold, brass, bronze, beryllium copper alloy, and the like. It is particularly effective when it is made of a metal material that is softer than dry lacquer.
Furthermore, although the back cover 13 is configured to include the cover glass 17, for example, the entire back cover 13 is formed of a metal base material, and the lacquer processing similar to that in the above embodiment is performed on a portion that contacts the skin. Also good. Thus, by making the part which touches the skin directly into a lacquer film in a state where urushiol is sufficiently polymerized, it is possible to prevent the occurrence of skin roughness due to the characteristics of lacquer.

In addition, the display member indicating “second”, “minute”, and “hour” is not limited to the second hand 22, the minute hand 23, and the hour hand 24, and display members having other shapes including a disk and a geometric shape may be used. It may be used.
Furthermore, when the wristwatch 1 is driven by power such as a battery, the display unit 5 is not limited to an analog display that displays the time and date on a display member as in the above embodiment, but the time and date are displayed. It may be a digital display that displays numbers. Examples of the display unit that performs digital display include a liquid crystal panel and an EL panel. In this case, for example, a dial may be arranged around a liquid crystal panel or an EL panel, and the dial may be a decorative item similar to the above embodiment.

  Moreover, in the said embodiment, although decorative articles, such as the decorative member 37 which gave the lacquer processing, were applied to the wristwatch 1, the decorative articles of the said embodiment were worn like brooches, necklaces, earrings, etc., for example. You may prepare for the accessories to wear.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
