Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is used for the purpose of increasing the decorative value of a vehicle by adhering it to the door and body of a vehicle such as an automobile, and for maintaining its aesthetic appearance over a long period of time. The present invention relates to a method of manufacturing a patterned decorative band for a vehicle.

(Prior Art) In general, this type of decorative band is manufactured using vinyl chloride as a constituent material. However, this decorative band mainly made of vinyl chloride has the disadvantage that its brightness deteriorates and the entire band changes color due to long-term use, making it very unsightly.

Furthermore, with conventional vinyl chloride tapes that are embedded with colored tapes such as gold or silver to create linear patterns of different colors, the polymerization of the upper and lower layers is not ensured and rainwater naturally infiltrates from the joints. Since the colored tape is dyed and discolored, it becomes very unsightly and cannot be used for a long period of time.

(Problems to be Solved by the Invention) Conventional decorative bands in which gold or silver colored tape is interposed between the upper layer and the lower layer do not allow for reliable integral molding as described above, resulting in contamination. Serious problems have arisen, such as discoloration and a very poor aesthetic appearance of the linear pattern.

The present invention was made in view of the above problems, and its purpose is to use an ionomer resin for the substrate of the decorative band, and to create a pattern on the surface of the substrate with colored foamed synthetic resin agents of different colors. A decorative band is produced by polymerizing the strips at predetermined intervals to form a pattern gap that appears in a straight line, and then polymerizing and depositing a transparent synthetic resin from the surfaces of the substrate and the pattern strip. The purpose is to permanently express a beautiful straight line pattern on the surface of the decorative band, and to prevent rainwater from penetrating into the interior to prevent permanent contamination. In addition, the uneven surface inside the colored foamed synthetic resin allows the surface to be drawn to reveal an excellent pattern with a sharp taste, and the inner patterned strip strengthens the entire decorative strip so that it can last for a long time. The point is that it has been used without any change over the years.

However, a decorative band that satisfies these essential parts has not been found at present, and the appearance of one is currently desired.

(Means for solving the problem) The technical means for solving the above-mentioned problem in the method for producing a decorative band according to the present invention are as follows.

A decorative band 1 made of synthetic resin is molded in the longitudinal direction, and a substrate 2 of a predetermined width made of ionomer resin is molded in the bottom part of the decorative band 1 made of synthetic resin. Longitudinal protrusions 7, 7 are formed on the surface of this substrate 2, and at least one strip of substrate 2 and pattern strips 3, 3, 3 made of colored foamed synthetic resin of different colors are predetermined inside. Polymerize at spaced positions. Pattern gaps 6, 6 formed by different colors of the substrate 2 between the pattern strips 3, 3, 3
are formed in a linear shape, and then a transparent synthetic resin layer 5 is polymerized and deposited on the entire surface of the substrate 2 and the pattern strips 3, 3, 3, and the whole is integrally molded. Therefore, according to the manufacturing method of the present invention, a beautiful linear pattern can be formed on the surface of the decorative strip 1, and the surface of the patterned strips 3, 3, 3 has apertures made of uneven colored foamed synthetic resin. The feature is that the processed and astringent design is made to stand out on the surface, increasing its decorative value.

(Example) Next, an example of the present invention will be described with reference to the drawings.A decorative band 1 that is attached to the surface of a vehicle, furniture, etc. to enhance the decorative effect is made entirely of synthetic resin and is molded into a longitudinal band shape. Ru. A base plate 2 of a predetermined width is formed on the decorative band 1 at the bottom in the longitudinal direction. This substrate 2 is, for example, as shown in FIG.
For example, a constituent material such as an ionomer resin is used. This substrate 2 has opposing protrusions 7, 7 formed on both sides of the surface along the longitudinal direction to ensure polymerization. Next, as shown in FIG. The strips 3, 3, 3 are sequentially polymerized at predetermined intervals. Several protruding stripes 8 and concave stripes 9 are alternately formed along the longitudinal direction on a part of the pattern strips 3, 3, 3 on the surface.

Furthermore, the structure is such that pattern gaps 6, 6 forming a linear pattern are formed between the pattern strips 3, 3, 3.

Further, as shown in Fig. 3C, a transparent synthetic resin layer 5 is polymerized and deposited on the entire surface of the substrate 2 and the base pattern strips 3, 3, 3, so that the whole is integrally molded. It is. Further, as shown in FIG. 1, adhesives 10, 10 are bonded to the bottom of the substrate 2 of the decorative band 1 on both sides in the longitudinal direction, and the adhesives 10,
It has a structure in which release papers 11, 11 are polymerized and adhered to the surface of 10.

(Function) In order to use the decorative band 1 manufactured as described above, the present invention requires peeling off the release paper 11 at the bottom of the substrate 2 to expose the adhesive 10 on the surface of a vehicle door, body, etc. Attach by pressing and gluing in place. Incidentally, it is of course possible to apply an adhesive instead of the adhesive 10 to the bottom of the substrate 2 for attachment.

(Effect of the invention) According to the patterned decorative band manufactured in this way,
The extremely beautiful linear bottoms of different colors are reflected on the surface of the transparent synthetic resin layer in a floating state, greatly enhancing the beauty and decorative value over the entire length, and the several strips of colored foam composite embedded in the decorative band. The patterned strip made of resin is interposed between the substrate 2 and the transparent synthetic resin layer and becomes integrally strong, serves as a core, and has the effect of significantly strengthening against expansion, contraction, and expansion. . Furthermore, since an ionomer resin is used as the constituent material of the substrate, it does not discolor over a long period of time, has excellent brightness, and has excellent resistance to bending and the like. In addition, one or more pattern strips containing colored foamed synthetic resin having a different color from the substrate are superimposed on the surface of the substrate with a predetermined gap, so that the substrate and the pattern strips are different from each other. This has the advantage that a linear pattern with beautiful colors can be freely formed, and a pattern gap can be formed between the substrate and the pattern strip, allowing the pattern to appear naturally. Furthermore, the patterned strip of colored foamed synthetic resin is sandwiched between the substrate and the upper transparent synthetic resin layer, and the surface of the colored foamed synthetic resin is pressed to form small ridges, creating a very beautiful patterned decorative surface. The interior of the patterned strip is pressed between the substrate and the transparent synthetic resin layer on the surface, making the whole tight and strong, and sufficiently resistant to bending and bending. can be expected.

Furthermore, since a transparent synthetic resin layer was polymerized and coated over the entire surface of the substrate and the pattern strip, they were molded together.
To strengthen the decorative band, and to obtain a patterned decorative band with excellent depth and design, in which the color of the patterned band strip and the color pattern of the pattern gap of the substrate emerge as a linear pattern on the surface. It is something that can be done.
