Description

Decorative elements {DECORATIVE MEMBER}

TECHNICAL FIELD This invention relates to the decorative member used for an elevator door panel, a car compartment wall panel, etc., for example.

In the conventional sandblasting technique, a mask material (photomask) is attached to a substrate to be processed such as glass or ceramic to obtain a processing surface having a predetermined shape (see Patent Document 1, for example).

However, in such a technique, chemicals for performing a film or a developing treatment are required every time, and waste water is generated by washing with water, and measures for preventing adverse effects on the environment are required.

Moreover, although the method of performing a sandblasting process without using a mask is also proposed (for example, refer patent document 2), in this method, it takes too much time to process a large area. Moreover, when the particle diameter of abrasive grain is about 100 micrometers-several mm, when a shape is formed by sandblasting process, sufficient precision is not obtained.

EMBODIMENT OF THE INVENTION Hereinafter, the highly suitable embodiment of this invention is described with reference to drawings.

Embodiment 1.

1 is a front view showing a decorative member according to Embodiment 1 of the present invention. In the figure, the substrate 1 consists of a metal panel. As the metal, for example, stainless steel, aluminum, aluminum alloy, magnesium alloy, titanium or titanium alloy can be used.

The base material 1 has a design surface 1a. Only one surface may be used as the design surface 1a among the several surfaces which comprise the base material 1, and multiple surfaces may be used as the design surface 1a. Polishing is performed on the design surface 1a so that glossiness may be improved.

The coating layer 2 is formed in the design surface 1a by apply | coating a coating material. The coating layer 2 contains the area | region by the transparent matte paint which becomes a matte state with hardening, and the area | region by the normal transparent paint different from a matte paint.

Even if a matte paint hardens | cures, the surface does not become smooth and a three-dimensional coating surface is formed so that small grains may form every grain. Moreover, a matte coating is hardened by irradiation of an ultraviolet-ray, for example. Specific examples of the matte paint are shown, for example, in Japanese Patent Laid-Open No. 6-312495 and Japanese Patent No. 3004897.

Matte paint and transparent paint are apply | coated as many dots. The coating layer 2 is provided with a pattern (drawing or drawing) by changing the coating density of the matte coating. Moreover, the pattern (drawing or drawing) is formed in the coating layer 2 also by the combination of the area | region with a matte paint and the area | region with a transparent paint.

Specifically, the transmissive region 3 shown by oblique lines in FIG. 1 is a region to which a transparent paint is applied, and the design surface 1a of the substrate 1 serving as the background is seen through the paint layer 2. The equality area | region 4 of FIG. 1 is the area | region apply | coated with the dot density (coating density) with which a matte paint was equal. In the change area | region 5 of FIG. 1, gradation can be provided to a shape by continuously changing the dot density of a matte coating material. The low-density region 6 in FIG. 1 is a region which is lower than the uniform region 4 but is coated with a matte paint at a (rough) uniform density.

FIG. 2 is an explanatory view showing an enlarged first example of the coating state of the matte paint in the uniform region 4 of FIG. 1, and FIG. 3 is the coating state of the matte coating in the uniform region 4 of FIG. 1. It is explanatory drawing which expands and shows a 2nd example. In FIG. 2, a plurality of center lines passing through the center of each dot cross each other at right angles. In FIG. 3, the plurality of center lines passing through the center of each dot intersect at a predetermined angle other than a right angle. 2 and 3, the dot diameter is d, and the distance between the centers of the dots is indicated by L. In FIG.

It is explanatory drawing which shows the experiment result which compared the difference of the finishing degree by the difference of the coating method of a matte paint. In the experiments, the glossiness change and reproducibility were subjectively evaluated to compare the degree of finishing. As a result of evaluation, (circle) is very good, (circle) is good, (triangle | delta) is a little problematic and x means that it is not practical.

In the experiment, the combination conditions of the dot diameter and the dot pitch were changed to evaluate the degree of finishing. The dot pitch represents the ratio of the distance between the centers of the dots to the dot diameter. For example, the dot pitch of 200% means that the distance L between the centers of dots in the FIGS. 2 and 3 is twice the dot diameter d.

As shown in FIG. 4, when dot diameter enlarges, reproducibility is stabilized, but a glossiness change cannot be confirmed. In contrast, the visually confirmed gloss change is apparent with the reduction in dot diameter. Moreover, when dot diameter enlarged, it was confirmed that adjacent dots are connected before a matte paint hardens | cures, and dot pitch is not ensured.

Therefore, the dot diameter of a matte coating is suitable to be 65 micrometers or less. Moreover, it is suitable to apply | coat a matte coating so that the distance between the centers of the dots adjacent to each other may be larger than a dot diameter, and may be 300% or less of a dot diameter.

Next, FIG. 5 is explanatory drawing which shows the other example of the coating method of the matte paint which concerns on Embodiment 1. FIG. In the example of FIG. 5, the matte paint is applied in a straight line. As a result, a straight line is drawn on the design surface 1a by a matte paint. In addition, gradation can be expressed by gradually changing the distance between the centers of dots adjacent to each other.

6 is explanatory drawing which shows still another example of the coating method of the matte coating material which concerns on Embodiment 1. FIG. In the example of FIG. 6, the matte paint is applied in a plurality of straight lines arranged in parallel at intervals from each other. In this way, by drawing a plurality of straight lines with a matte paint, a finish similar to hairline processing can be obtained.

7 is explanatory drawing which shows still another example of the coating method of the matte paint which concerns on Embodiment 1. FIG. In the example of FIG. 7, the matte paint is applied in a plurality of curved lines. In addition, the matte paint is applied to draw a plurality of circles overlapping each other. Thus, by drawing a plurality of curves with a matte paint, a finish similar to scratch finish can be obtained.

According to such a decorative member, the matte paint is applied as a plurality of dots, and the shape is formed in the paint layer 2 by changing the coating density of the matte paint, so that a large amount of waste liquid containing chromium or nickel and sandblast It is possible to prevent generation of dust, waste water for producing a mask, waste, various solvents, and the like, and a decorative member having excellent design can be obtained while sufficiently reducing the impact on the environment.

Moreover, since the shape is formed in the coating layer 2 also by the combination of the area | regions 4, 5, 6 by a matte paint, and the area | region 3 by a transparent paint, the decorative member with high designability which is more abundant in change is made. You can get it.

Moreover, since the grinding | polishing process is given to the design surface 1a used as the background of the coating layer 2 so that glossiness may be improved, the high-quality finish can be obtained utilizing the metal gloss of the design surface 1a.
