Abstract

PURPOSE:To draw any elaborate pattern as an engraved groove in a repeating manner, by forming said engraved groove on a film-coated layer by scanning and radiating laser beams. CONSTITUTION:A black epoxy resin paint is applied on the surface of a base member 1 to form a film-coated layer 2. Then, by using a laser processor controlled by a computer, a registered pattern programmed in advance is called and a groove 3 is engraved by the pattern on the film-coated layer 2. A transparent epoxy resin solution 4 which is a type drying at ordinary temperatures is injected along the groove 3. Decorating foil powders 5 made of gold-color metal powders, silver-color metal powders, glass particles, ceramic particles or the like are scattered at suitable positions on the epoxy resin solution 4. Then, while the resin solution 4 and the decorating foil powders 5 are being depressed, a surplus of the solution 4' and powders 5' is wiped off. At this time, the decorative foil powders 5 scattered on the dried film-coated layer 2 are removed by a suction device. The base member 1 becomes flat accordingly. Then, after drying and hardening the base member 1 at ordinary temperatures, a decorative plate is obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for efficiently carving grooves with elaborate shapes on a painted film by skillfully utilizing a pseudo-inlay processing method, specifically, a laser beam. We have developed a new highly industrial surface processing method that applies a pseudo-inlaid finish to the carved grooves using synthetic resin liquid and decorative foil powder, and is suitable for use not only in the surface decoration of furniture and daily necessities, but also in office work. Fixtures and Accessories - 1 Furthermore, it is expected to have a wide range of applications as a surface decoration technology for eyeglass frames.

[Conventional technology and technical issues to be solved] Since ancient times, Japan has had chinkin and Ill! (Sansai)
These highly artistic surface decoration techniques have been passed down, and today, furniture, lacquerware, and other everyday items decorated with this technique are the subject of much fascination among connoisseurs. This is because the ``chinkin technique'' is a surface treatment in which a needle-shaped pattern is engraved on the slope surface, lacquer is rubbed on top of the pattern, gold leaf is placed on top of the pattern, and the gold leaf is adhered to the grooves by pressing the gold leaf with cotton. The rag technique is also used to unevenly apply colored lacquer to the parts to be decorated, and then sharpen it to form a rhino skin surface with a similar needle-shaped pattern engraved on it. All of these methods require highly skilled manual techniques such as needle-shaping, and they also use lacquer, which is a very expensive paint. This is because it was not a technology that could be adopted.

The present invention has been made in view of the fact that the conventional surface processing techniques such as gilding and rhinoplasty do not meet the requirements of mass production and economical cost as mentioned above. To provide a new type of surface processing method, that is, a pseudo-chinkin processing method, which can inexpensively mass-produce luxurious surface cosmetic products that can be mistaken for products made using the chinkin or sanzai technique.

[Technical Means Adopted to Achieve the Object] The means adopted by the inventor to achieve the above object will be described below with reference to the accompanying drawings.

That is, the present invention includes a forming means for forming a painted film layer 2 on the surface of a target base material l, and a method of carving grooves 3 in a desired pattern by scanning and irradiating the formed film layer 2 with a laser beam. A laser irradiation groove-forming flat film is provided, and lacquer or the coating layer 2 is applied to the carved grooves 3.
Decorative foil powder embedding means for injecting a translucent synthetic resin liquid 4 with good adhesiveness into the resin liquid and scattering gold leaf powder or other decorative foil powder 5 onto the resin liquid to settle it in the resin liquid; A flat membrane for wiping excess coated foil is used to remove excess resin liquid 4'' and excess decorative foil powder 5'', and a curing treatment means is used to cure the injected resin liquid 4, and these are applied sequentially and in stages. As a result, we have realized a pseudo-chinkin force U construction method that can satisfy the above-mentioned technical objectives.

〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments shown in the accompanying drawings. In addition, FIG. 1 is a front view of a decorative board showing a Kikusui design produced by an example method according to the present invention;
Figures 2 to 6 are step-by-step explanations of the method of this embodiment, with Figure 2 being a cross-sectional view of the base material, and Figure 3 showing the state in which a paint film layer has been formed on the same base material. 4 is a cross-sectional view of the coating liquid MRI with grooves formed by scanning laser beam irradiation, and FIG. 5 is a decorative foil powder formed by injecting a translucent resin liquid onto the coating layer. FIG. 6 is a cross-sectional view of a state in which excess resin liquid and excess decorative foil powder have been removed, and FIG. 7 is a partially enlarged cross-sectional view of FIG. 5.

In the drawings, the reference numeral P indicates a decorative board produced by the method of this embodiment, and the reference numeral indicates a pseudo Chinkin Kikusui pattern applied on the decorative board. Thus, such a decorative board is produced as follows.

First, a black epoxy resin paint is applied to the surface of the base material 1 shown in FIG. 2 to form a painted film layer 2 as shown in FIG. 3.

Next, using a combinator-controlled laser processing machine (not shown) (YAG Laser Marker LAY-724 manufactured by Toshiba Kaihatsu), a pre-programmed registered pattern (Kikusui) is called up, and the above-mentioned coating is applied as shown in Fig. 4. Grooves 3 are carved on the coating layer 2.

Next, a transparent room temperature drying type epoxy resin liquid 4 is injected along the groove 3, and decorative foil powder such as gold metal powder, silver metal powder, glass particles, ceramic particles, etc. is poured onto the injected epoxy resin liquid 4. After spraying the resin solution 4 and the decorative foil powder 5 at appropriate locations (see FIGS. 5 and 7), the excess resin solution 4° and 5° is wiped off while pressing down the resin solution 4 and the decorative foil powder 5. In addition, at this time,
The decorative foil powder 5 scattered on the dried paint film layer 2 is removed by a suction machine (not shown).

In this way, the target substrate 1 becomes a flat state as shown in FIG. 6, and when it is dried and cured at room temperature, a decorative board as shown in FIG. 1 is obtained.

Although the method of this embodiment is generally as described above, the present invention is by no means limited to the method of the embodiment described above, and various design changes are possible within the scope of claims j. For example, a paint film layer 2 formed on a base material 1
The material does not necessarily have to be epoxy resin; it can be formed with any paint as long as it has good adhesion to the synthetic resin liquid 5 to be used afterwards; The liquid 4 does not necessarily have to be an epoxy resin as long as it has a certain degree of translucency or transparency, and an acrylic urethane resin or an ultraviolet curable resin liquid can also be used.

[Effects of the present invention]

As is clear from the above explanation, the method of the present invention employs a method of forming grooves in the paint film layer by scanning laser beam irradiation, so the desired pattern etc. can be registered in the computer. As long as it is set, the laser beam can be scanned and irradiated freely, and even the most delicate design patterns can be drawn repeatedly as grooves.
There is no need for the high degree of manual skill required in the technique.

In addition, in the method of the present invention, it is possible to produce products that are falsely made from synthetic resins, such as those made from ancient gilded metals or rhinoceroses, so that products that have hitherto been out of reach of the general public can be provided at low prices. This can greatly contribute to improving the design value of products and reducing economic costs.
