Abstract
Description
本発明は、長期にわたって植物の変色を防止することができる、植物材料封入用樹脂組成物、及び植物材料含有成型体に関するものである。 The present invention relates to a plant material encapsulating resin composition and a plant material-containing molded product that can prevent plant discoloration over a long period of time.
従来、生花（植物の葉、茎、花など）を加工した各種装飾品が製造されている。例えば、水分を予め除去した自然の草花や乾燥花を、透明樹脂で被覆したブローチやイヤリングなどの装飾品（例えば、特許文献１、２）、または植物材料を、熱可塑性のボードなどの間に挟み、加熱・加圧加工した装飾品（特許文献３）が知られている。 Conventionally, various decorative products obtained by processing fresh flowers (plant leaves, stems, flowers, etc.) have been manufactured. For example, natural flowers and dried flowers from which moisture has been removed in advance, decorative articles such as brooches and earrings coated with a transparent resin (for example, Patent Documents 1 and 2), or plant materials between thermoplastic boards, etc. A decorative article (Patent Document 3) that has been sandwiched, heated and pressurized is known.
しかし、上記のような装飾品のように、植物材料を透明樹脂で被覆した場合、経時で植物が変色、退色するおそれがあり、これを解決する手段としては被覆する樹脂を厚くする必要があった。そのため、このように樹脂被覆によって製造される装飾品としては、ブローチなどの小物がほとんどであり、建材等の大型化には適用され難かった。一方、熱可塑性フィルム（板）によって加熱・加圧加工する場合、比較的大きな建材などの製造も可能であるが、特殊な機械が必要であり、工程が煩雑となるおそれがある。また、このようなフィルム（板）状のものは、形状が限られるため、適用可能な施工場所に制限を受けるおそれがある。 However, when the plant material is coated with a transparent resin as in the case of the above-mentioned ornament, the plant may be discolored or discolored over time, and as a means for solving this, it is necessary to thicken the resin to be coated. It was. For this reason, as ornaments manufactured by resin coating in this manner, most small items such as brooches are difficult to apply to enlargement of building materials and the like. On the other hand, when heating and pressurizing with a thermoplastic film (plate), relatively large building materials can be manufactured, but a special machine is required and the process may be complicated. Moreover, since the shape of such a film (plate) is limited, there is a possibility that the applicable construction place is limited.
本発明は、上述のような問題点に鑑みなされたものであり、植物材料を封入するための樹脂組成物であって、封入した植物材料の変色、および退色を抑制することができ、建材などに容易に応用できる樹脂組成物を得ることを目的とするものである。さらに、この樹脂組成物を用いて植物材料が封入された成型体を得ることを目的とする。 The present invention has been made in view of the above-described problems, and is a resin composition for encapsulating plant material, which can suppress discoloration and fading of the encapsulated plant material, such as a building material. It aims at obtaining the resin composition which can be applied easily to. Furthermore, it aims at obtaining the molding in which the plant material was enclosed using this resin composition.
本発明者は、上記目的を達成するため鋭意検討を行った結果、特定の樹脂組成物が、上記目的を達成できることを見出し、本発明を完成するに至った。すなわち、本発明の樹脂組成物は、下記の特徴を有するものである。 As a result of intensive studies to achieve the above object, the present inventors have found that a specific resin composition can achieve the above object, and have completed the present invention.

The molded object enclosed with the resin composition which contains less than a weight part in the state which can see a plant material visually.
本発明の樹脂組成物は、植物材料を封入する場合、成型体の厚みを比較的薄くしても、長期にわたり植物の変色、退色を抑制することができ、さらに優れた耐水性を得ることができる。また、高温加熱・加圧等の特殊な機械が不要であり、簡単に製造することができ、様々な形状の成型体を製造することもできる。このような利点により、小物等の装飾品以外に、建材等にも簡単に適用することができる。 When encapsulating plant materials, the resin composition of the present invention can suppress discoloration and fading of plants over a long period of time, even if the thickness of the molded body is relatively thin, and can obtain excellent water resistance. it can.

（成型体の製造）
植物材料は、バラを花弁（赤）と葉に分け、それぞれを洗浄、平滑化及び乾燥処理をしたものを使用した。
(Manufacture of molded products)
As the plant material, roses were divided into petals (red) and leaves, which were washed, smoothed and dried.
（実施例１）
アルミ板に樹脂組成物Ａを塗付し、次いで、葉と花弁をそれぞれ、任意に配置した。さらに、樹脂組成物Ａを被覆厚が概ね０．８ｍｍとなるように成型し、４日間硬化、２３℃下で養生させ試験体を作製した。このときの試験体の厚みは１．０ｍｍ（基材は除く）であった。以下の評価を実施した。結果を表２に示す。
Example 1
Resin composition A was applied to an aluminum plate, and then leaves and petals were arbitrarily arranged. Furthermore, the resin composition A was molded so as to have a coating thickness of approximately 0.8 mm, cured for 4 days, and cured at 23 ° C. to prepare a test specimen. The thickness of the test body at this time was 1.0 mm (excluding the base material). The following evaluation was performed. The results are shown in Table 2.
・評価１（屋内露光）
屋内の窓辺に試験体１を設置し、この試験体の１４日後の色相変化を、目視で評価した。評価基準は、評価開始時と比較し、色相変化がないものを◎、著しく変化したものを×とし、４段階（◎＞○＞△＞×）で評価した。
・評価２（浸水屋内露光）
２５℃の水に試験体を浸漬させたものを、屋内の窓辺に設置し、１４日間浸漬後、試験体を水から引き上げ、乾燥させた後、色相変化を、評価１と同様の方法で評価した。
・ Evaluation 1 (Indoor exposure)
The test body 1 was installed on the indoor window side, and the hue change after 14 days of this test body was visually evaluated. The evaluation criteria were evaluated in four stages (◎>◯>Δ> ×), with ◎ indicating that there was no change in hue and × indicating a marked change compared to when the evaluation was started.
・ Evaluation 2 (Submerged indoor exposure)
A specimen immersed in water at 25 ° C. was placed on an indoor window, immersed for 14 days, the specimen was pulled up from the water and dried, and the hue change was evaluated in the same manner as in Evaluation 1. did.
