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 drawback 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. This has the disadvantage that the colored tape becomes contaminated and discolored, making it very unsightly and making it impossible to use it 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-mentioned problems, and its purpose is to use an ionomer resin for the substrate of the decorative band, and to coat the surface of this substrate with colored foamed synthetic resin agents of different colors. Patterned strips are polymerized at predetermined intervals to form pattern gaps that appear linear, and then a transparent synthetic resin layer is polymerized and applied from the surfaces of the substrate and the patterned strips to form a decorative strip. The purpose of this product 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 creates an excellent pattern with a sharp drawing process on the surface, and the internal pattern strip strengthens the overall decorative band, making it durable for a long time. The point is that it can be used without any change.

However, a decorative band that satisfies these demands has not yet been found, and the development of one is currently desired.

(Means for Solving the Problems) The technical means for solving the above-mentioned problems in the decorative band manufacturing method of the present invention are as follows.

The decorative band (1) is molded from synthetic resin in the longitudinal direction.A substrate (21) of a predetermined width made of longitudinal ionomer is molded on the bottom.A longitudinal protrusion (7) is formed on the surface of this substrate +21. ) ('71 is formed, and on the inside there is at least one substrate (-) and a pattern strip (31+31) made of colored foamed synthetic resin of different colors. (31+31
is formed in a straight line, and then a transparent synthetic resin layer +5 is applied to the entire surface of the substrate (2:) and the pattern strip +31131131.
1 is polymerized and deposited 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 strip +31131131 has a drawn texture made of uneven colored foamed synthetic resin. The point is that a tasteful design is brought to the surface to enhance the decorative value.

(Embodiment) Next, an embodiment of the present invention will be explained with reference to the drawings.The decorative strip (1), which is adsorbed on the surface of a vehicle, furniture, etc. to enhance the decorative effect, is made entirely of synthetic resin and is shaped like a longitudinal strip. It is molded into. For this decorative band (11, a substrate (21) of a predetermined width located at the bottom in the longitudinal direction is molded. This substrate 12 is made of a constituent material such as ionomer resin, for example, as shown in FIG. .This substrate (21) has protrusions (7) (7) formed opposite to each other on both sides of the surface along the longitudinal direction to ensure polymerization.
As shown in the figure, there is at least one strip in the longitudinal direction between the protruding stripes m (η) on the surface of the substrate (2 and patterned strips of colored foamed synthetic resin, such as those containing different colored metallics + 3).
1 (31) are sequentially polymerized at predetermined intervals.

This surface pattern strip # (31 (31 (31) has several convex stripes and concave portions (9) alternately formed along the longitudinal direction in a part of the strip.

Furthermore, the pattern strip +31 +31 (between 31,
The structure is such that a pattern gap +61161 is formed as a linear pattern.

Furthermore, as shown in FIG. 3(C), a transparent synthetic resin layer +51 is polymerized over the entire surface of the substrate (21) and the patterned strip +31+31131, thereby integrally molding the whole. In addition, on the bottom of the substrate (2) of the decorative band (1), as shown in FIG.
)(10) and the adhesive (10)(1
It has a structure in which release paper (11011) is polymerized and adhered to the surface of 0).

(For bleeding) In order to use the decorative band (1) manufactured as described above, the present invention requires peeling off the release paper (11) on the bottom of the substrate (2) and attaching the adhesive to the surface of the door, body, etc. of a vehicle. (10) is exposed and attached by pressure bonding to a predetermined position.

Incidentally, it is of course possible to apply an adhesive instead of the adhesive (10) on the bottom of the substrate (2) for attachment.

(Effect of the invention) According to the patterned decorative band manufactured in this way, an extremely beautiful straight line pattern of different colors is reflected on the surface of the transparent synthetic resin layer in a floating state, and the entire length has a very beautiful appearance and decorative value. The patterned strip made of several colored foamed synthetic resin layers buried inside the decorative strip is interposed between the substrate (21) and the transparent synthetic resin layer and becomes integrally strong. In addition, it has the effect of making it extremely tough against expansion, contraction, and expansion.In addition, since ionomer resin is used as the constituent material of the substrate, it has excellent brightness without discoloration over a long period of time, and has the effect of being resistant to bending, etc. Also, by superimposing one or more patterned strips containing colored foamed synthetic resin in a different color from the substrate on the surface of the substrate at predetermined intervals, it is possible to It has the effect that a beautiful linear pattern in a different color from the pattern strip can be freely formed, and a pattern gap that naturally reveals the pattern can be formed between the substrate and the pattern strip. The patterned strip of 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 to reveal a very beautiful patterned decorative surface. In addition, 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 it is expected that it will be able to sufficiently handle bending and curving. .

Furthermore, since a transparent synthetic resin layer is polymerized and integrally formed over the entire surface of the substrate and pattern strip, the decorative strip is strengthened, and the color of the pattern strip and the gap between the patterns on the substrate can be adjusted. The colored patterns emerge on the surface as a linear pattern, making it possible to obtain a decorative band with a pattern that has depth and is excellent in design.
