Description

[Detailed Description of the Invention] The present invention relates to a synthetic resin coated body in which the surface of a core material is coated with a synthetic resin.

Frame materials for display shelves, handles for motsupu, and other materials for assembling miscellaneous goods are processed in various ways, such as drilling, crushing, and bending, depending on the purpose of use. When used as an assembly material, the synthetic resin coating must be able to be easily subjected to the various processes listed above, and when these processes are applied, the synthetic resin coating layer must separate from the core material. There must be no peeling or cracking or damage to the coating layer. Furthermore, giving the synthetic resin coating a special luster or color not only increases the commercial value of the synthetic resin coating but also expands its uses.

The present invention improves its commercial value by providing a synthetic resin coating that has the workability required for the above-mentioned miscellaneous goods assembly materials and has a special luster and color, especially an aesthetic appearance called pearlescent. The purpose is to improve the performance and expand the applications.

As shown in FIG. 1, the synthetic resin covering according to the present invention has a core material 1 and a base layer 2 in close contact with the base layer 2.
The core material 1 is covered with a synthetic resin coating layer 4 consisting of a base layer 2 and a surface layer 3.

A metal tube such as a steel tube is used as the core material 1 . By using a metal tube, it has excellent rigidity and is highly workable.

The base layer 2 must be made of a synthetic resin mixed with metal powder and have translucency. The synthetic resin in this case is one that has flexibility and impact resistance to the extent that it will not crack or peel even if it is bent or crushed while being in close contact with the core material 1, for example. Blends of polyvinyl chloride or methyl methacrylate and acrylic rubber can be suitably used. The metal powder mixed into the base layer 2 includes fine powder made only of metal, as well as
Includes thin plate-like or scale-like forms. It also includes inorganic fine particles coated with metal. Specifically, there are aluminum powder, natural mica coated with titanium oxide, and natural mica coated with titanium oxide and iron oxide. This metal powder may be mixed in to the extent that the surface layer 3 can maintain its translucency.

The surface layer 3 must be made of an acrylic synthetic resin mixed with a pigment and have translucency. As the acrylic synthetic resin, one having a glossy surface and rich luster, such as methyl methacrylate, can be suitably used. The pigment mixed in the surface layer 3 may be either inorganic or organic,
Also, even if it is a colored pigment such as blue, green, yellow, or red, ash,
It may be a colorless pigment such as silver or white. Furthermore, the pigment may be mixed within a range that does not cause the surface layer 3 to lose its translucency. This surface layer 3 is laminated to the base layer 2, but in this case it is better to heat-seal it than to use an adhesive. That is, when an adhesive is used, the adhesive layer obstructs light entering the base layer 2 and light reflected from the base layer 3, which deteriorates the aesthetic appearance accordingly.
Heat fusion does not cause such inconvenience. In order to obtain a good laminated state by thermal fusion, it is desirable to use a synthetic resin that is highly compatible with acrylic synthetic resin, specifically polyvinyl chloride, as the base layer 2.

The above-mentioned synthetic resin coating has excellent workability and has a special luster and color tone, making it aesthetically pleasing.

In other words, regarding workability, the surface layer 3 whose base material is an acrylic synthetic resin that lacks flexibility is not directly laminated on the core material 1, but has a high bonding strength with the core material 1 and a certain degree of flexibility. Since it is laminated on the base layer 2 whose base material is a synthetic resin such as polyvinyl chloride, the surface layer 3 is integrated with the base layer 2 during bending or crushing, and the core material 1 is deformed. You will be able to follow it well. Therefore, if the surface layer is laminated directly onto the core material, even if the surface layer is processed to peel from the core material or cause cracks or cracks, the surface layer 3 will not peel off due to such processing. It will not cause any cracks or cracks.

Next, regarding the aesthetic appearance, the surface layer 3 is made of acrylic synthetic resin as a base material and pigments are mixed in it, and the base layer 2 is mixed with metal powder, which gives it a special luster. and the color tone is visually recognized.

That is, the light incident on the base layer 2 becomes colored light by passing through the surface layer 3, and this colored light is transmitted by the individual metal powder particles or the aggregate layer of metal powder particles existing inside the surface layer 3. This causes multiple diffuse reflections and repeated refraction when the reflected light passes through the synthetic resin of the base layer 2 and the acrylic synthetic resin of the surface layer 3.
It produces a special luster that is different from mere metallic luster, that is, a soft, deep, dull luster (pearl luster) that is very similar to that emitted by pearls. Also,
The light directly reflected from the surface layer 3 without reaching the base layer 2 becomes colored light, which is visually recognized as being combined with the above-mentioned pearlescent luster. In addition, the surface layer 3 exhibits a high level of transparency and luster that is unique to acrylic synthetic resins, so the synergistic interaction of these creates a visual aesthetic that has never been seen before, making the product even more appealing. This can significantly contribute to increasing value.

In Figure 2, the core material 1 of the synthetic resin coating is a steel pipe,
While covering the outer surface with a synthetic resin coating layer 4,
The example shows a finished product with a diameter of about 20 mm. Such synthetic resin coatings are used, for example, as frame materials for display shelves and handles for motsupu. As explained in FIG. 1, the synthetic resin layer 4 consists of the base layer 2 closely adhered to the core material 1 and the surface layer 3 laminated thereon by heat fusion. In this case, the base layer 2
The size is 5 to 150μ, and the size is 50 to 150μ relative to the thickness.
When 2 to 4 wt% of transparent metal powder in the form of a plate approximately 100 times larger than that of natural mica coated with titanium oxide is mixed,
Excellent pearlescent luster with silver to iridescent coloring was visible. Moreover, the pearlescent luster at this time was in good harmony with the color tone of the base layer 2. In the above, the amount of metal powder mixed in is set to 2 to 4 wt% with respect to the total weight of the base layer 2. This is because the amount of metal powder mixed in the base layer 2 is set to 2 to 4 wt% with respect to the total weight of the base layer 2. This is a result based on the aim of maintaining a certain degree of light transmittance, and is not intended to limit the amount of metal powder mixed therein. Further, when this synthetic resin coating is used as the above-described frame material or handle, it is sufficient that the base layer 2 has a thickness of about 200 μm and the surface layer 3 has a thickness of about 100 μm.

As is clear from the detailed description above, the synthetic resin coating according to the present invention is characterized in that the light reflected by the metal powder mixed in the base layer is transmitted through the base layer and the surface layer while being refracted; It exhibits a pearlescent luster with a unique color due to the synergistic effect of the light and the light reflected on the surface layer exhibiting a special color tone with excellent transparency and luster unique to acrylic synthetic resin. Therefore, it is aesthetically superior. Therefore, the product value can be improved and the range of applications can be expanded. In addition, by laminating the surface layer made of acrylic synthetic resin on the base layer, we have prevented the surface layer from cracking, cracking, or peeling during processing such as drilling, bending, and crushing. Although it can produce the transparency and gloss characteristic of synthetic resins, it is highly processable.
