(産業上の利用分野)
本発明は軽量で折れにくいプラスチックス製眼鎮枠に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lightweight and unbreakable plastic eyepiece frame.
(従来技術および問題点)
元来、眼鏡枠は金属から出発し、セルロイド、アセテー
トプラスチックスが主流であったが、近年ファツション
性、例能性の点で、やIくて折れない樹脂製眼鏡枠のニ
ーズが高まりつつある。(Prior art and problems) Originally, eyeglass frames were made of metal, and celluloid and acetate plastics were the mainstream, but in recent years, resin glasses that are durable and unbreakable have become popular in terms of fashionability and functionality. The need for frames is increasing.
眼鏡枠は、通常大枠と呼ばれる枠の断面積が大きい種類
と、ぞうでない細枠に大別される。両名の明確な区別の
基準はないが、デザイン上あるいは機能面で枠を細くす
るにしたがって、その材質l、:要求される剛性は高く
なっていくのが一般である。Eyeglass frames are generally divided into two types: large frames, which have a large cross-sectional area, and narrow frames. Although there is no clear standard for distinguishing between the two, generally speaking, as the frame becomes thinner in terms of design or function, the required rigidity of the material increases.
ところで、眼鏡枠の材質として、致命的な欠陥は;Jl
lれである。おJ:ぞ枠として選定されtJろ樹脂は、
枠のいかなる形状においてら90°以上の曲げで割れて
はならない。こうした理由から、眼鏡枠として用いられ

い、即も曲げ弾性率が高く、かつ曲げ破断伸度も高いこ
とである。By the way, the fatal flaw in the material of eyeglass frames is;
It's late. The tJ resin selected as the OJ:zo frame is
The frame must not crack when bent by more than 90° in any shape. For these reasons, the mechanical properties required of the material used for eyeglass frames are that it is hard and does not break when bent, that is, it has a high flexural modulus and a high bending elongation at break.
一方、熱可塑性樹脂の側から見れば、曲げ(ip外性率
高いことと曲げ破断伸度が高いことは、一般に相反する
性質である。本発明名はこの相反する樹脂の特性の矛J
V点を解決すべく、鋭Qω1究を重ねた結果、粘f1の
高いポリアミド樹脂に複数の充填物を混合することによ

て折れにくい細枠の優れたプラスヂックス製眼鏡枠の発
明をなりに至ったものである。On the other hand, from the perspective of thermoplastic resins, high bending (IP) properties and high bending elongation at break are generally contradictory properties.
In order to solve the V point, we conducted extensive research on Qω1 and found that it could be solved by mixing multiple fillers with polyamide resin with high viscosity f1.Based on this knowledge, we developed an excellent thin frame that is lightweight and hard to break. This led to the invention of a plastic eyeglass frame.
