【考案の詳細な説明】 （産業上の利用分野） この考案は、鉛等の樹脂製装身具に関する。[Detailed explanation of the idea] (Industrial application field) This invention relates to accessories made of resin such as lead.

（従来の技術） 鉛等の装身具を樹脂製とする場合には、通常、
熱可塑性樹脂や熱硬化性樹脂が素材とされてい
る。(Prior art) When accessories such as lead are made of resin, usually
The material is thermoplastic resin or thermosetting resin.

長所を有するが、耐熱性に劣るという欠点も有し
ている。 Since the thermoplastic resin has a linear polymer structure, the intermolecular binding force is small even at low heating temperatures, and the thermoplastic resin has the property of being softened and melted. Therefore, it has the advantage that it can be easily molded into a desired pattern, but it also has the disadvantage of poor heat resistance.

している。 On the other hand, the above-mentioned thermosetting resin is obtained by heating a plurality of raw materials to soften them, and through intermolecular reactions in this softened state, the resin changes into a solid resin having a crosslinked structure. Therefore, it has the advantage of being excellent in heat resistance, but because of its insoluble and infusible nature, it must be molded within the short time required for the above-mentioned intermolecular reaction, and therefore has the disadvantage that this processing is troublesome. are doing.

ところで、装身具には外観上の体裁と耐熱性が
共に要求されるため、これが樹脂製の場合には従
来より次のように形成されたものがある。 By the way, since accessories are required to have both good appearance and heat resistance, when they are made of resin, they have conventionally been formed as follows.

即ち、上記両樹脂を相互補完させるようにした
もので、所望の柄模様に成形加工した熱可塑性の

板材とで接着剤を介して挟み付けられ、かつ、外
面が切削加工により仕上げられている。 In other words, the above-mentioned resins are made to complement each other, and a thermoplastic resin handle plate material molded into a desired pattern is bonded to a thermosetting resin transparent plate material and a substrate material via an adhesive. It is sandwiched and the outer surface is finished by cutting.

（考案が解決しようとする問題点） ところで、本来異種樹脂間では接着性が悪いた
めに、熱可塑性の樹脂製柄板材と熱硬化性の樹脂
製透明板材や基板材とが互いに剥離するというお
それがある。(Problem that the invention aims to solve) By the way, since adhesive properties between different types of resins are inherently poor, there is a risk that the thermoplastic resin handle plate material and the thermosetting resin transparent plate material or substrate material may peel off from each other. There is.

また、最終切削加工による摩擦熱は直接刃物か
ら上記柄板材へ伝わるが、この柄板材は熱可塑性
であるためこれが変色変形するおそれがある。 Further, the frictional heat generated by the final cutting process is directly transmitted from the blade to the handle plate material, but since this handle plate material is thermoplastic, there is a risk that the handle plate material may become discolored and deformed.

また、加工後においても、各板材間の熱膨張係
数の差により、直射日光等の熱源で、熱可塑性の
樹脂製柄板材の変形により装身具に上記のような
剥離が生じやすいという不都合もある。 In addition, even after processing, due to the difference in thermal expansion coefficient between each plate material, there is a disadvantage that the above-mentioned peeling of the accessory is likely to occur due to deformation of the thermoplastic resin handle plate material by a heat source such as direct sunlight.

The base member and the transparent member are made of a thermosetting resin that is filled into the base member so as to encapsulate the plate member within the base member. Since they are made of resin, they are strongly adhered to each other. Therefore, even though the plate member interposed between the base member and the transparent member is thermoplastic, it is prevented from peeling off. In addition, when cutting the outer surface, since the thermoplastic plate member is covered with a thermosetting resin, the plate member is not directly processed, so that discoloration and deformation of the plate member is prevented. Furthermore,
When dyeing a button by applying high-temperature dye to the button after processing or boiling the button in the dye, the thermoplastic plate member is covered with thermosetting resin, so the plate member is coated with heat. This prevents deformation and peeling.
