That is, the present invention places a first flexible mold on a receiving plate, pours a thermosetting synthetic resin liquid onto the first flexible mold,
After placing a second flexible mold on top of the thermosetting synthetic resin liquid, the thermosetting synthetic resin liquid is semi-gelled to form a semi-gelled thermosetting synthetic resin, and then the thermosetting synthetic resin liquid is semi-gelled. Manufacture of a three-dimensional structural ornament by separating a thermosetting synthetic resin from a receiving plate together with a first flexible mold and a second flexible mold, placing it on a shaping mold, shaping it, and then hardening it. It concerns the method. The method for manufacturing a three-dimensional decorative article according to the present invention will be explained in more detail below.

This first flexible mold is placed on a receiving plate such as a glass plate, and then a thermosetting synthetic resin liquid is poured onto the first flexible mold. As the thermosetting synthetic resin liquid used here, unsaturated polyester resin, epoxy resin, epoxy acrylate resin, etc. can be used. A curing accelerator, catalyst, pigment, dye, etc. are added to these thermosetting synthetic resin liquids as necessary. Here, when pouring the thermosetting synthetic resin liquid onto the first flexible mold, in order to increase the strength of the decorative product, use a glass fiber material such as glass cloth, nylon, vinylon, tetron, etc. It is also possible to embed a synthetic fiber reinforcing material such as a woven fabric or a non-woven fabric in a thermosetting synthetic resin liquid. In addition, in order to provide decorative variations to the decorative item, the decorative body may be embedded alone or in combination with the reinforcing material in a thermosetting synthetic resin liquid containing natural and/or artificial decorative bodies. .

に押じつけて賦形させる。 Next, a semi-gelled thermosetting synthetic resin (thermosetting synthetic resin in a state where fluidity is almost gone, but is not completely cured and has flexibility) is placed in a first flexible mold. The second flexible mold is removed from the receiver together with the second flexible mold, and all or part of it is placed on a previously prepared shaping mold and allowed to fit naturally into the shaping mold by its own weight, or by appropriate pressing means. Press it into a shaping mold and shape it.
ここで使用される賦形用型としては所望の形状

After completely curing or semi-curing to a state where the shape does not collapse even when removed from the mold, the mold is removed from the shaping mold, heated and completely cured, and the first flexible mold and the second flexible mold are formed. It can be peeled off from the cured thermosetting synthetic resin or left attached to the product.

る。 As is clear from the above, the method for manufacturing a three-dimensional structural ornament of the present invention allows thermosetting synthetic resin to be poured in a flat state that is easy to work with, and also allows the thermosetting synthetic resin to be poured into a semi-gelled state when the thermosetting synthetic resin liquid is semi-gelled. By utilizing the non-flowability and flexibility of thermosetting synthetic resin and the flexibility provided on both sides, it can be placed on a shaping mold having a desired shape and shaped. This makes it extremely easy to operate and improves work efficiency.

The same second polyester film 8 is spread and placed, and the air accumulated between the thermosetting synthetic resin liquid 6 and the second polyester film 8 is removed. Thereafter, it is allowed to stand at room temperature (23-25%) for about 5 minutes to form a semi-gel. Next, the semi-gelled thermosetting synthetic resin 9 sandwiched between the first polyester film 5 and the second polyester film 8 is lifted up and separated from the glass receiving plate 3 and placed on a shaping mold 10 to be described later. It is spread out and placed, and the part placed on the mold 10 is pressed to conform to the shape of the mold 10, and the lower part 11 not in contact with the mold 10 is left hanging naturally. Next, after being allowed to stand at room temperature for about 10 to 30 minutes, the lower part 11 of the semi-gelled thermosetting synthetic resin 9 is cut at irregular locations to give the desired shape.

つた。 When the mold does not lose its shape even when removed, the semi-gelled thermosetting synthetic resin 9 is pulled out from the mold 10 while being sandwiched between the first polyester film 5 and the second polyester film 8. After removing the mold and placing it in a heated oven to completely cure, the first polyester film 5 and the second polyester film 8 are peeled off from the cured thermosetting synthetic resin to obtain a molded product. A decorative item was obtained by drilling a hole for a lighting fixture connection tool in the upper part of the molded product. The obtained ornaments could be used in lampshades to produce excellent decorative effects.

て趣きのあるものであつた。Example 2 As shown in Fig. 4, a cylindrical mold 1 was cut out from a polystyrene foam block as a shaping mold.
A first polyester film 5 manufactured under the same conditions as Example 1 was applied to the outer surface of the mold 10 using
Then, the semi-gelled thermosetting synthetic resin 9 sandwiched between the second polyester film 8 is wound around the semi-gelled thermosetting synthetic resin 9, and the joint portion 19 on the circumference of the semi-gelled thermosetting synthetic resin 9 is slightly removed. After overlapping the polyester films 5, a thermosetting synthetic resin liquid 6 having the same composition as that used in Example 1 was poured into the joint portion 19, and the top was sealed with the outermost second polyester film 8. Perform the joining process. And the thermosetting synthetic resin liquid 6 of the joint part 19
After gelation has progressed, the ends of the semi-gelled thermosetting synthetic resin 9 in the longitudinal direction of the cylinder are trimmed, and when the mold is ready to be removed, it is removed from the cylindrical mold 10 and processed. Thoroughly harden in a warm oven, and
A molded product is obtained by peeling the polyester film 5 and the second polyester film 8 from the cured thermosetting synthetic resin, and an unsaturated polyester having a smooth bottom surface at one opening of the cylindrical molded product is obtained. A decorative article was obtained by pasting the resin plate 20 with an adhesive. The obtained ornament was used as a flower vase and was tasteful.
