JPS5945189A - Formation of mark on automotive part - Google Patents

Abstract

PURPOSE:To form a mark having a decorative effect integral with parts by forcing the mark into the body of a part with a heat press and coating it with an urethane resin. CONSTITUTION:A mark is printed on a molding formed with a black theremoplastic resin using a white ink and undergoes a heat press. A mirror surface with a better gloss is created to make the mark clearer enhancing the display effect thereof. Then, an urethane resin is mixed with a pearl pigment at a rate of 0.5% and a coating is applied thereon to the thickness of 0.05mm.. A part from a reflection of the pearl pigment upon the body of the black resin, this makes the mark printed white look whiter and adds the reflection of the pearl pigment to it further improving the decorative effect thereof. It is also possible that a mark composed of three colors, that is white, orange and red, utilizing a transfer paper is transferred by heat pressing and coated with the urethane resin or the mark coposed by etching an aluminum plate is bonded with a double adhesive tape and coated with a dye-colored urethane. Thus, a mark embedded part is formed with a high decorative effect.

Description

[Detailed description of the invention] Marks for automobiles include those that indicate the roadway, vehicle name, etc. Marks can be formed either when attached directly to the vehicle body or when used by being incorporated into other parts. There is also Ai. Among the marks incorporated in other parts, there are those that are integrated into one part and those that are formed by incorporating a mark that is a single item.

Marks indicate roadways, vehicle types, and vehicle names, so they must be highly decorative and have good display effects. However, if the mark is integrated with parts, it can be printed or colored by adding unevenness to the parts. It is difficult to compose and create a decorative effect. Attaching the mark using separate parts may feel strange, and the separate parts are expensive, and it is difficult to construct the desired mark.

The present invention provides a method for eliminating such defects and forming a mark on a part with a decorative effect.

Parts into which marks are incorporated include moldings, radiator grilles, lamp bezels, etc., and methods for forming marks on moldings include printing marks on the main body, and providing unevenness on the main body and coloring those parts.

When formed by the method of the present invention, the mark is integrated with the main body, and there is a layer of urethane resin on the surface, resulting in a molding with a high decorative effect and a single surface with no unevenness. The mark can be formed on the main body to be decorated by any means such as printing the mark on the main body, transferring the mark, or adhering a mark made of metal foil, and there is no limitation to the method.

Next, once the mark is formed, it is pressed into the main body using a heat press. The mark and main body are integrated by this press-fitting, and this alone has a decorative effect and increases the culm quality, but in the present invention, to further enhance this effect, and to protect the mark, it is coated with transparent urethane resin. .

The urethane resin can be colored or mixed with foil powder to create a color effect and enhance the decorative effect. The effects of Examples will be explained below.

Example 1 A mark was printed with white ink on a molding molded from a black thermoplastic resin, and the molding was hot pressed.

The mark has good gloss and a mirror surface, making the mark clear and displaying a high effect. Next, 0.5 inch of JR-L pigment was mixed into the urethane resin and coated to a thickness of 0.05 fi. The black resin body also reflects the e-le pigment, but the white printed mark looks whiter, and with the addition of the tukur pigment reflection, the decorative effect is much improved compared to simply printed marks.

Example 2 A mark composed of three colors, white, orange, and red, was transferred to a lamp bezel molded from black thermoplastic resin using a transfer paper using a heat press, and the lamp bezel was coated with urethane resin. It is possible to form an unprecedented design mark on the lamp bezel,
I was able to make 4 lamps with marks that are highly decorative.

Example 3 A mark formed by etching a 005 aluminum plate was adhered to a grille molded from a dark and colored thermoplastic resin using double-sided adhesive tape, and then press-fitted with a 504/- hot press at 150°C.

As a result, marks that could previously be created without plating the grille and painting the mark in a dark color were now possible without plating.

Next, the urethane resin was colored with yellow dye and coated to a thickness of 0.02 mm. We were able to create a radiator grille with a highly decorative effect, with the marking part being gold and the rest remaining dark and colored.
