Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing decorative objects such as wall hangings, desk tops, frames, etc. using resin.

Traditionally, raden is a type of lacquer craft decoration that utilizes the unique luster of shell fragments.

This Rasen technique involves inserting thin or thick shell pieces into lacquer or a base, or pasting them on a slope, and polishing them together with lacquer to coat the surface with the base material of the shell pieces. It was used to create a decorative effect, and the series of production processes required a lot of time and skill, and required extremely advanced techniques.

Therefore, the decorations had to be expensive because they were made using various pieces of shells and took a lot of time and effort.

Moreover, since the shell pieces are exposed on the surface because they are fitted or pasted onto the lacquer or base surface, the decorations may peel off or wear out due to long-term use.

This invention solves the above-mentioned defects, and is a decorative item using resin that can be easily and quickly produced using a handicraft sieve, and that allows the unique brilliance of the shell fragments to be admired for a long period of time without peeling. To provide a manufacturing method.

An embodiment embodying the present invention will be described below with reference to FIGS. 1 to 3. A transparent synthetic resin plate G of an appropriate size is constructed such that a transparent portion with an appropriate pattern is formed on the plate. Turn the back side of G up and draw a pattern O as shown in Figure 2 on the back side with an opaque coloring material such as paint.

Next, on the back surface of the resin plate G in the transparent part through which the light passes,
A transparent unsaturated polyester resin liquid P to which a catalyst for curing at room temperature and a curing accelerator have been added in advance is spread thinly as shown in FIG. 3A.

Then, on top of the spread, thin plate-shaped shell pieces S cut into pieces larger than the transparent part are pasted on each location as shown in Figure 3B, and lightly pressed with fingers or a stick on the pasting surface. Make sure that there are no air bubbles in the shell pieces S
Make sure to spread it evenly over the surface.

In addition, at this time, the shell piece S was directly pasted on two surfaces of the unsaturated polyester resin liquid poured on the resin plate G, but a small amount of the same unsaturated polyester resin liquid P was applied on the surface of the shell piece S by four cloths. You may wear it.

As described above, since the shell piece larger than the transparent part is attached, no gap is formed between the outer peripheral edge of the transparent part and the outer peripheral edge of the shell piece.

Also, if the shell pieces are smaller than the transparent part, several shell pieces should be arranged without any gaps.

When the unsaturated polyester resin liquid P has hardened to the point that it does not flow, the entire upper surface of the shell piece S is coated with a thin layer of colored unsaturated polyester resin liquid CP colored with the same coloring agent as the shell piece S. Scroll, each shell piece S
The back side of the package is sealed.

The rest is completed by curing the colored unsaturated polyester resin liquid CP.

In this way, decorations using shell pieces can be easily created by hand.

In this completed state, when looking at the resin plate G from the front side, you can see that the shell piece S stuck inside the transparent part of the design
The brilliance of the pattern stands out and you can admire the design with its own unique taste.

In addition, in this way, the shell pieces S are mixed with the unsaturated polyester resin liquid P.
The colored unsaturated polyester resin liquid CP is sealed without any gaps and is adhered to the resin plate G, so that it is thin and not bulky as a whole, and the colored unsaturated polyester resin liquid CP
, shell piece S, unsaturated polyester resin liquid P and resin plate G
Since it is composed of an integrated state, it gives off a wet shine, and when the shell piece S is viewed from the front side of the resin plate G, it can be seen more clearly, and the surface of the shell piece S can be polished without polishing. It has a similar effect.

In addition, since the shell pieces S are covered with the unsaturated polyester resin liquid P and the colored unsaturated polyester resin liquid CP, even if the shell pieces S are extremely thin or brittle, they can be protected. Since the entire back surface of the shell piece S was coated with the colored unsaturated polyester resin liquid CP colored in the same color as the shell piece S, there is a gap between the outer periphery of the shell piece S and the outer periphery of the transparent part, or between each shell piece S. Even if gaps are formed, they are not easily visible and do not impair the decorative effect at all.

Furthermore, since the colored unsaturated polyester resin liquid CP is poured after the transparent unsaturated polyester resin liquid P between the shell pieces S and the resin plate G has hardened to the point where it does not flow, the colored unsaturated polyester resin The liquid CP does not mix into the transparent unsaturated polyester resin liquid P and the transparent resin liquid P is not contaminated.

Therefore, the color of the shell pieces S is not impaired, and it is possible to create an ornament that effectively utilizes the color of the shell pieces S.

Next, a second embodiment of the present invention will be explained based on FIG. 4. After drawing the pattern O with opaque paint to form a perspective view as in the first embodiment, as shown in FIG. 4A, An unsaturated polyester resin liquid P containing a room temperature curing catalyst and a curing accelerator is poured into the transparent area.

Next, as shown in FIG. 4B, shell pieces S cut in advance to a size matching each transparent part are fitted into each transparent part and pasted in the same manner as in the first embodiment. A colored unsaturated polyester resin liquid CP colored in the same color as the shell piece S is poured over the shell piece S as shown in FIG. 4C, and is sealed and hardened.

Therefore, even if the method of the second embodiment is used, the same effects as those of the first embodiment can be obtained.

In addition to the first and second embodiments described above, this invention can also be embodied in the following embodiments.

(a) Although the transparent synthetic resin plate G was used in each of the above embodiments, a translucent synthetic resin plate may be used, and a glass plate may be used in place of the synthetic resin plate G.

(b) In each of the above embodiments, paint or the like was used to draw the design on the synthetic resin plate G, but in order to simplify the production or to produce products in large quantities, the back side of the glass plate or synthetic resin plate G To form a design by ground printing on the surface, or to form the outline of a design by pasting or hot pressing a styrene film or baked film with a design printed on it with unsaturated polyester resin liquid P on the back side of the film, or by other methods. The shell pieces are pasted on transparent areas using unsaturated polyester resin.

(c) Thin shell piece S whose surface is not polished in each of the above embodiments
However, use one with a polished surface or a piece of shell with a thick wall.

) Using each example, rings, brooches, pendants,
Applicable to the decoration of small accessories such as earrings, tie pins, stick ties, hairpins, obi clips, buttons, hand mirrors, compacts, etc., and room accessories such as ashtrays, flower vases, letter boxes, tinsel boxes, tables, mirror stands, etc.

Furthermore, the present invention is not limited to shell pieces that are adhered to a translucent or transparent plate with an unsaturated polyester resin liquid, but may also be applied to objects that produce the same or similar luster as the shell pieces, such as pearl printing. A piece of paper, a pearl foil film (burl mylar sheet), etc., is shaped into an appropriate shape or wrinkled in large numbers, and then adhered to a translucent or transparent plate using an unsaturated polyester resin liquid, and then dried with these pearl foil films, etc. Alternatively, it is also within the technical scope of the present invention to attach a combination of colored petals, leaf pieces, feathers, metal pieces, mineral pieces, or powder.

As described in detail above, this invention enables the creation of ornaments that make effective use of the color of the shell pieces, and also has the effect that the created decorations are thin and do not become bulky as a whole. It is.
