Description

本発明は、透光性で平板状のプラスチック成形体に、印刷やコーティングを施し、その裏面側に、他のプラスチック成形体を超音波で融着した超音波融着体に関するものである。   The present invention relates to an ultrasonic fusion bonded body obtained by printing or coating a light-transmitting, flat plate-shaped plastic molded body and fusing another plastic molded body with ultrasonic waves on the back side thereof.

従来、プラスチック成形体と他のプラスチック成形体とを、超音波融着法で融着する場合には、材質が同じプラスチック成形体間か又は分子構造が似ていて相溶性のある材質のプラスチック成形体間、例えば、ポリフェニレンオキサイドと汎用ポリスチレン、ＡＢＳ樹脂とポリメタクリル酸メチルなどに限られており、このため、印刷やコーティングなどの二次加工が必要な場合には、図２に示すように、プラスチック成形体（１１０）の他のプラスチック成形体（１２０）と融着しない表面に、印刷層（１１３）やコーティング層（１１４）を施していた。なお、溶着のためのエネルギーダイレクター（図２では、１15）は、必要に応じて、どちらか一方のプラスチック成形体（図２では、１１０) の融着面に形成していた。   Conventionally, when a plastic molded body and another plastic molded body are fused by the ultrasonic fusion method, the plastic molding is made of compatible materials between the same plastic molded bodies or similar in molecular structure. Between the bodies, for example, polyphenylene oxide and general-purpose polystyrene, limited to ABS resin and polymethyl methacrylate, etc. For this reason, when secondary processing such as printing or coating is required, as shown in FIG. A printed layer (113) and a coating layer (114) were applied to the surface of the plastic molded body (110) that is not fused with another plastic molded body (120). In addition, the energy director (115 in FIG. 2) for welding was formed on the fusion surface of one of the plastic molded bodies (110 in FIG. 2) as necessary.

しかしながら、プラスチック成形体の融着しない表面に、印刷やコーティングなどの二次加工を施した場合には、デザイン上から見て奥行きを欠き単純な表現しかできなかった。また、超音波融着法で融着するときに、ホーン（振動伝達金具）との接触によって印刷やコーティングなどの二次加工面に擦れや傷が付き易かった。また、超音波融着には夾雑物シール性があり、融着側に印刷を施した場合、振動や熱が局部的に集中して、印刷やコーティングの二次加工層が破壊されることがあった。   However, when a secondary process such as printing or coating was applied to the non-fused surface of the plastic molded body, it was only possible to express simply with a lack of depth as viewed from the design. In addition, when fusing by the ultrasonic fusing method, the secondary processing surface such as printing or coating is easily rubbed or scratched by contact with a horn (vibration transmission metal fitting). Ultrasonic fusion also has a foreign matter sealing property, and when printing is performed on the fusion side, vibration and heat are concentrated locally, and the secondary processing layer of printing and coating may be destroyed. there were.

本発明は、上述の従来のプラスチック成形体の超音波融着における問題点を解決したものであり、奥行きのある二次加工が可能で、超音波融着時の二次加工層の変化による外観性への影響が少なく、材質が異なるプラスチック成形体間でも超音波融着が可能な超音波融着体を提供するものである。   The present invention solves the problems in ultrasonic fusion of the above-described conventional plastic molded body, enables deep secondary processing, and appearance by changing the secondary processing layer during ultrasonic fusion. It is an object of the present invention to provide an ultrasonic welded body that can be ultrasonically welded even between plastic molded products having different effects on properties.

すなわち、本発明の第１の発明は、透光性で平板状のプラスチック成形体の裏面に、イソシア−ウレタン樹脂を主成分とする二次加工層を形成し、この二次加工層の裏面に、アクリル−ポリカ−ボネート樹脂を主成分とする接着層を形成し、この接着層の裏面側に、融着面にエネルギーダイレクターを設けた他のプラスチック成形体を、超音波融着法により融着したことを特徴とする超音波融着である。   That is, according to the first aspect of the present invention, a secondary processing layer mainly composed of isocyanurethane resin is formed on the back surface of a light-transmissive, flat plastic molded body, and the back surface of the secondary processing layer is formed. Then, an adhesive layer mainly composed of an acrylic-polycarbonate resin is formed, and another plastic molded body provided with an energy director on the fusion surface on the back side of the adhesive layer is fused by an ultrasonic fusion method. Ultrasonic fusion characterized by wearing.

次に、本発明の第２の発明は、前記イソシア−ウレタン樹脂を主成分とする二次加工層の厚みが、少なくとも１０μｍ以上であることを特徴とする請求項１記載の超音波融着体である。   Next, according to a second aspect of the present invention, the thickness of the secondary processing layer mainly composed of the isocyanurethane resin is at least 10 μm or more. It is.

そして、本発明の第３の発明は、前記アクリル−ポリカ−ボネート樹脂を主成分とする接着層の厚みが、少なくとも１２μｍ以上であることを特徴とする請求項１又は請求項２記載の超音波融着体である。   According to a third aspect of the present invention, in the ultrasonic wave according to claim 1 or 2, the thickness of the adhesive layer mainly composed of the acrylic-polycarbonate resin is at least 12 μm or more. It is a fused body.

本発明の超音波融着体は、透光性で平板状のプラスチック成形体の裏面に、イソシア−
ウレタン樹脂を主成分とするインキで印刷やコーティングによる二次加工層を形成しているため、従来のプラスチック成形体の表面に二次加工層を形成した場合と比較して、奥行きのある二次加工が可能である。 The ultrasonic fusion bonded body of the present invention has an isocyanate on the back surface of a light-transmitting, flat plate-shaped plastic molded body.
Since the secondary processing layer is formed by printing or coating with ink containing urethane resin as the main component, the secondary layer with depth compared to the case where the secondary processing layer is formed on the surface of the conventional plastic molded body Processing is possible.

また、本発明の超音波融着体は、透光性で平板状のプラスチック成形体の裏面に、イソシア−ウレタン樹脂を主成分とするインキで印刷やコーティングによる二次加工層を形成しているため、超音波融着時にホーンが二次加工層に直接に接触することがないので変化が少なく、また、プラスチック成形体の表面からは二次加工層の変化が見にくく、外観性への影響が極めて少ない。   In the ultrasonic fusion bonded body of the present invention, a secondary processed layer is formed by printing or coating with an ink containing isocyanurethane resin as a main component on the back surface of a transparent and flat plastic molded body. Therefore, there is little change because the horn does not directly contact the secondary processed layer during ultrasonic fusion, and the change of the secondary processed layer is difficult to see from the surface of the plastic molded body, which affects the appearance. Very few.

また、本発明の超音波融着体は、二次加工層の裏面にアクリル−ポリカ−ボネート樹脂を主成分とする接着層を形成し、この接着層の裏面側に、他のプラスチック成形体を超音波融着法により融着するため、材質が異なるプラスチック成形体間でも超音波融着が可能となる。   Further, the ultrasonic fusion bonded body of the present invention has an adhesive layer mainly composed of acrylic-polycarbonate resin formed on the back surface of the secondary processing layer, and another plastic molded body is formed on the back surface side of the adhesive layer. Since fusion is performed by an ultrasonic fusion method, ultrasonic fusion can be performed between plastic molded bodies having different materials.

次に、本発明の超音波融着体の一実施形態について、図を用いて詳細に説明する。   Next, an embodiment of the ultrasonic fusion bonded body of the present invention will be described in detail with reference to the drawings.

図１は、本実施形態における、裏面に二次加工層と接着層を形成した成形体の裏面に、エネルギーダイレクターを形成した他の成形体を、超音波融着法により融着するときの状態を示す説明図である。   FIG. 1 shows a case where another molded body in which an energy director is formed on the back surface of a molded body in which a secondary processing layer and an adhesive layer are formed on the back surface in the present embodiment. It is explanatory drawing which shows a state.

本実施形態の超音波融着体は、図１に示すように、透光性で平板状のポリメタクリル酸メチル成形体（１１０）の裏面に、イソシア−ウレタン樹脂を主成分とする二次加工層（１１１）を形成し、この二次加工層の裏面に、アクリル−ポリカ−ボネート樹脂を主成分とする接着層（１１２）を形成し、この接着層の裏面側に、融着面にエネルギーダイレクター（１２１）を設けたＡＢＳ樹脂成形体（１２０）を、超音波融着法により融着するものである。ＡＢＳ樹脂成形体（１２０）を、超音波融着装置のアンビル（２２０）（固定治具）にエネルギーダイレクターを形成した融着面を上にして固定し、ポリメタクリル酸メチル成形体（１１０）の裏面に形成する接着層（１１２）と重ね合わせて、ホーン（振動伝達金具）で加圧し、超音波振動をポリメタクリル酸メチル成形体に伝達して、ポリメタクリル酸メチル成形体とＡＢＳ樹脂成形体との接触面に発生する摩擦熱により融着させて、超音波融着体を作製するものである。   As shown in FIG. 1, the ultrasonic fusion product of this embodiment is a secondary process mainly composed of isocyanurethane resin on the back surface of a light-transmitting, flat plate-shaped polymethyl methacrylate molded body (110). A layer (111) is formed, and an adhesive layer (112) mainly composed of acrylic-polycarbonate resin is formed on the back surface of the secondary processed layer, and energy is applied to the fusion surface on the back surface side of the adhesive layer. The ABS resin molding (120) provided with the director (121) is fused by an ultrasonic fusing method. The ABS resin molded body (120) is fixed to the anvil (220) (fixing jig) of the ultrasonic fusion apparatus with the fusion surface on which the energy director is formed facing upward, and the polymethyl methacrylate molded body (110). Is superposed on the adhesive layer (112) formed on the back surface of the steel plate and pressed with a horn (vibration transmission fitting) to transmit ultrasonic vibrations to the polymethyl methacrylate molded body, and the polymethyl methacrylate molded body and ABS resin molded An ultrasonic fusion bonded body is produced by fusing by frictional heat generated on the contact surface with the body.
