Description

  The present invention relates to a resin spectacle component having a decorative property.

  In recent years, spectacle frames have been used as fashion products in various colors on the surface of the frame in order to improve the decorativeness. In the case of resin eyeglass parts, it is required to consider the fashionability.

  As a method for manufacturing a resin spectacle part, there is also a method of cutting a patterned plate material into a part shape. In this method, the plate material itself is composed of multiple colors, and a resin-made spectacle part having a sense of depth can be created. However, the plate material needs to be produced in large quantities due to problems in the manufacturing process, and further, the shape of the part needs to be adjusted only by cutting, which increases the cost.

  As another method for manufacturing a resin spectacle part, a means for molding a resin into a part shape is taken. Many of the manufacturing methods are manufactured because eyeglass parts can be manufactured at low cost and it is easy to increase color variations with the same shape. However, the surface of the molded resin is uniform, and it has been used to apply a decorative pattern by printing or dyeing after molding. However, the dyed pattern is often faded by sweat that comes in contact with the spectacle frame or hair styling, and the printed pattern has an ink layer on the surface, so it feels rough and the hair when the spectacle frame is attached and detached. Problems such as removal due to wear.

  Addition by dyeing, printing, or the like is poor in color depth, and in order to produce a high-quality and deeper pattern, it is necessary to superimpose multiple colors, which is expensive.

The present invention has been made based on such a technical background.
In other words, the present invention provides a resin spectacle part having a durable, deep feeling pattern using a molding means that can be manufactured relatively inexpensively. Furthermore, the manufacturing method of the spectacles part is provided.

  That is, the present invention is (1) a decorative part obtained by molding a transparent resin containing a scaly bright pigment, wherein the part of the surface of the decorative part is removed and oriented near the surface of the molded part. The present invention resides in a resin decorative spectacle part characterized in that a cut surface having a reflectance different from that of a molded product surface is provided by exposing an orientation side surface of the bright pigment.

  The present invention also relates to (2) a decorative part obtained by molding a transparent resin containing a scaly bright pigment, wherein a part of the surface of the decorative part is oriented near the surface of the molded part. By cutting away at an angle different from that of the orientation surface, the angle formed between the orientation surface and the newly formed surface and the thickness of the orientation surface are reduced, so that the color of the flake-like bright pigment changes due to the change in reflected light. Lies in resin decorative spectacle parts characterized by having different cut surfaces.

  The present invention is also (3) a decorative part obtained by molding a transparent resin containing a scaly bright pigment, wherein the part of the decorative part is oriented near the surface of the molded product. The present invention resides in a resin decorative spectacle part characterized in that it is cut in a direction perpendicular to the surface and provided with a cut surface that does not reflect the scaly pigment.

  Further, the present invention is the resin product according to (1) or (2) or (3) or (4), wherein the resin decorative part is a modern or arm used for a spectacle frame. It exists in decorative spectacle parts.

  Further, the present invention is the resin product according to (5), wherein the scaly bright pigment has a maximum diameter of 60 microns or less, and is (1) or (2) or (3) or (4) It exists in decorative spectacle parts.

  The present invention also relates to (6) a step of forming a transparent resin containing a scaly bright pigment into a substantially part shape; and the scaly bright pigment that orients a part of the surface of the molded product in the vicinity of the surface of the molded product. Generated by cutting the orientation surface of the scaly glitter pigment and cutting the surface of the molded product including the removed portion by a grinding process for uniforming the roughness of the surface of the molded product. The present invention resides in a method for manufacturing a resin decorative spectacle part characterized in that a portion where the reflected light of a scaly glittering pigment is different is provided in response to a change in the angle formed by the formed surface.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the resin spectacles part which has the depth and changed the hue using the manufacturing method cheap and mass-productive called shaping | molding.
In addition, since the color changes only in the scraped portion, it is possible to provide a spectacle resin component having a three-dimensional feeling in which the shape and the color change coincide with each other.

  The flow of resin during molding of a resin spectacle part containing a scale-like bright pigment will be described taking a modern part as an example.

  Resin that has flowed in from the gate provided at the modern tip (commonly referred to as “sink only”) is filled while being cooled from the mold surface. Therefore, Newtonian flow occurs in the mold, and the flow velocity is small near the mold surface and increases toward the inside.

  When scaly bright pigment is mixed in the resin, it is oriented along the mold surface due to the difference in flow velocity, and is cooled and fixed as it is (leafing layer). Therefore, in the vicinity of the surface layer, a molded product in which the scaly bright pigment has an orientation surface along the mold surface is generated. Therefore, in the molded product, the scaly bright pigment is totally reflected along the surface. (See Fig. 1 and Fig. 2)

  Moreover, since the flow rate difference does not occur at the center of the molded product, the scale-like bright pigment is not oriented and is fixed in the resin in the random direction.

  In addition, although there is no direct relationship with the effect of this invention, the orientation surface of the scale-like bright pigment is produced | generated also around the arm insertion hole of the modern center part. This orientation surface pushes the peripheral resin apart when the core is forcibly inserted to form the insertion hole before filling the molding resin into the mold and cooling and solidifying. It is the orientation of the scaly bright pigment produced with the deformation of the resin at that time.

  The scaly glitter pigment refers to a flaky pigment that is blended in a paint, a molded resin, or the like, produces a metallic tone or a pearl tone color, has a mirror-finished surface, and regularly reflects light. Generally, flaky pigments made of metals such as aluminum and silver, pearl pigments coated with a colored film such as titanium oxide or iron oxide on the surface of mica powder, and metal deposited by vapor deposition on the polyester film surface After that, there are organic pearl-like pigments cut into fine shapes.

  As described above, the molded product in which the scaly glitter pigment is oriented in the vicinity of the surface has a uniform color tone of a metall tone or a pearl tone (hereinafter simply referred to as a pearl tone) due to the reflection of the scaly glitter pigment.

  The surface of the resin spectacle part molded in this way having a single color with a pearl tone is removed by cutting or polishing to provide a new cut surface having a direction different from the orientation surface. On this cut surface, an angle different from the orientation direction of the scaly bright pigment, that is, an orientation side surface appears. The intensity of the pearl tone changes due to the change of the angle between the orientation plane and the cut plane that have been cut off and appear. Specifically, as the angle increases, the color tone of the pearl becomes weaker. When the angle is 90 degrees, that is, when the scaly pigment is viewed from the side, the color tone of the pearl is completely lost.

  A modern cross-sectional view of the present invention is shown.

FIG.

This will be described in more detail based on the above.
In the vicinity of the surface (C1) and the periphery of the cored bar insertion hole (A), there are orientation planes of the scaly bright pigment. C2 represents a portion where the scaly bright pigment is not oriented and fixed in a random manner. The cut surface of D1-D4 is provided in the modern shape thus formed. D1-D4 shows the cut surface provided by cutting. In addition, although E1-E2 also shows a cut surface, the modern surface shape and orientation surface before cutting are also described collectively.

Of these cut surfaces, D1-D2 becomes larger as the orientation of the scaly bright pigment and the angle formed by the cut surface approach D2, and the surface thickness becomes thinner. As a result, the reflected light gradually weakens.
In D2-D3, a scale-like bright pigment fixed in a random state inside the modern appears. Therefore, it shows a completely different aspect of pearl.
In D3-D4, the angle formed by the orientation surface and the cut surface is almost perpendicular, and the pearly feeling is lost.

  As described above, the modern surface passes through E2-D1 in which the scaly glitter pigment is totally reflected, D1-D2 in which the pearl reflected light is reduced, and D2-D3 in which the pearl feeling is different and is fixed at random. , It changes to D3-D4 without pearl feeling.

  Needless to say, it is also possible to provide a cut surface without reducing the depth of cutting and providing a randomly fixed layer.

As described above, generally used scaly bright pigments exhibit a white metallic luster or white pearl color like aluminum or titanium oxide-coated mica powder.
For this reason, when the pearl tone strength (metallic tone strength) is reduced, the overall color tone is a change in tone, such as blue to light blue and pink to red.

  Use a scaly glitter pigment that has colored reflected light, such as blue light for red light, and change the color of the transparent organic pigment that is mixed together with a color tone different from that of the scaly glitter pigment. Is also possible.

  The maximum diameter of the scaly bright pigment is suitably 60 microns or less. When a scaly glitter pigment of 60 microns or more is used, the scaly glitter pigment is peeled off when creating a cut surface due to the difference between the scaly glitter pigment hardness and the hardness of the transparent resin to be mixed. It is hard to come out.

  As described above, the explanation has been given by taking Modern as an example, but there are decorative parts having a similar effect even in parts such as arms and plastic eyebrows that contain scale-like bright pigment and can be partially removed after molding. can get.
