本考案は２液反応型接着剤をポットライフに関係なく使
用でき、接着剤の硬化時間を短縮することができるよう
な接着剤塗布ノズルに関するものである。[Detailed Description of the Invention] The present invention relates to an adhesive application nozzle that can use a two-component reactive adhesive regardless of its pot life and shorten the curing time of the adhesive.
最近、アクリルやエポキシを主成分とした接着剤として
、２液反応型接着剤が開発されている。Recently, two-component reactive adhesives have been developed as adhesives mainly composed of acrylic or epoxy.
すなわち、アクリル系接着剤を例にとると、アクリル接
着剤Ａ液と、アクリル接着剤Ｂ液とを接触あるいは混合
することにより硬化反応を起して硬化し接着するといっ
たものである。That is, taking an acrylic adhesive as an example, when acrylic adhesive liquid A and acrylic adhesive liquid B are brought into contact with each other or mixed, a curing reaction occurs and the adhesive is cured and bonded.
従来においては、この２液反応型接着剤をあらかじめ混
合し、これを１本の接着剤塗布ノズルより注出させて用
いていた。Conventionally, this two-component reactive adhesive has been mixed in advance and used by pouring it out from a single adhesive application nozzle.
この方法は硬化時間が短縮できる確実な方法であるが、
この２液反応型接着剤には、混合後、直ちに硬化反応が
開始されるため、ポットライフが短かく、ポットライフ
中に使用できる量のみの調合しかできず、生産性の点で
問題があった。This method is a surefire way to shorten curing time, but
Because this two-component reactive adhesive starts a curing reaction immediately after mixing, it has a short pot life, and only the amount that can be used during the pot life can be prepared, which poses problems in terms of productivity. Ta.
また、他の方法としては、接着剤塗布ノズル中で攪拌し
て、注出する方法も開発されており、この場合は連続使
用する場合には硬化により接着剤塗布ノズルがつまって
しまうといったことが発生しないが、長時間休止すると
接着剤が硬化し、ノズルがつまってしまうため、次に使
用するときにノズルを取換えたり、または休止時には冷
温保存する必要があり、あまり実用的とはいえないもの
であった。In addition, another method has been developed in which the adhesive is stirred in the adhesive application nozzle and poured out, but in this case, the adhesive application nozzle may become clogged due to curing when used continuously. Although this does not occur, the adhesive hardens and the nozzle becomes clogged if the product is left idle for a long time, so the nozzle must be replaced the next time it is used, or it must be stored at a cold temperature when it is not used, which is not very practical. It was something.
本考案は以上のような従来の欠点を除去するものであり
、ポットライフに関係なく使用でき、接着剤の硬化時間
を短縮することができる接着剤塗布ノズルを提供するこ
とを目的とするものである。The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, and to provide an adhesive application nozzle that can be used regardless of the pot life and shorten the curing time of the adhesive. be.
以下、本考案を一実施例の図面第１図〜第２図により説
明する。Hereinafter, the present invention will be explained with reference to FIGS. 1 and 2 of the drawings of one embodiment.
まず、第１図において、１は複数本の内ノズルで、この
内ノズル１の外周には大径の外ノズル２が配置され、こ
の複数本の内ノズル１には一方の接着剤Ａ液が供給され
るパイプ３が、外ノズル２には接着剤Ｂ液が供給される
パイプ４が接続されている。First, in FIG. 1, reference numeral 1 indicates a plurality of inner nozzles, and a large-diameter outer nozzle 2 is arranged on the outer periphery of the inner nozzle 1. A pipe 3 is connected to the outer nozzle 2, and a pipe 4 to which adhesive B liquid is supplied is connected to the outer nozzle 2.
しかも、上記内ノズル１は外ノズル２の先端よりも多少
突出するように構成されている。Moreover, the inner nozzle 1 is configured to protrude somewhat more than the tip of the outer nozzle 2.
また、上記接着剤Ａ液、Ｂ液のいずれか一方には反応開
始剤が混合されている。Moreover, a reaction initiator is mixed in either one of the adhesive liquids A and B.
この構成によれば、内ノズル１の先端から注出された位
置で接着剤Ａ液とＢ液が接触または混合されて、ここで
初めて硬化反応を起すことになる。According to this configuration, adhesives A and B come into contact or mix at the position where they are poured out from the tip of the inner nozzle 1, and a curing reaction occurs for the first time here.
この構成の接着剤塗布ノズルを用いた場合と、Ａ液の上
にＢ液を重ねるように塗布した場合の硬化時間について
実験した結果を下表１に示す。Table 1 below shows the results of an experiment regarding the curing time when using an adhesive application nozzle with this configuration and when applying liquid B in an overlapping manner on liquid A.
なお、用いる接着剤はアクリル系２液反応型接着剤であ
る。Note that the adhesive used is an acrylic two-component reactive adhesive.
この結果から硬化時間が約２０％促進されていることが
わかる。This result shows that the curing time is accelerated by about 20%.
これは、接着剤Ａ液とＢ液の接触部分の増大がこのよう
な結果となって表われることを示している。This indicates that the contact area between adhesives A and B is increased as a result.
また、ノズル中で混合する場合と本考案の接着剤塗布ノ
ズルを用いた場合の硬化時間と効果の比較を下表２に示
す。Further, Table 2 below shows a comparison of the curing time and effect when mixing in a nozzle and when using the adhesive application nozzle of the present invention.
以上のように本考案の接着剤塗布ノズルは構成されるた
め、２液反応型接着剤を用いるのに、連続使用も可能と
なり、途中で長時間休止してもノズルが接着剤の硬化に
よりつまってしまうといったこともなく、生産性を計る
上で著しく有利となり、また、内ノズルが複数本のため
２つの接着剤の接触や混合が迅速に行なわれて硬化時間
の短縮化も計れるなど実用性に富んだものとすることが
でき、しかも一方の接着剤液が複数に分割されているた
め、外ノズルから注出される他方の接着剤液との反応硬
化を未硬化部分を残すことなく完全に行うことができる
。As the adhesive application nozzle of the present invention is constructed as described above, continuous use is possible even when using a two-component reactive adhesive, and even if the nozzle is stopped for a long time in the middle, the nozzle will not become clogged due to hardening of the adhesive. It is extremely advantageous in terms of productivity as it does not cause any problems, and since there are multiple inner nozzles, the two adhesives can contact and mix quickly, shortening the curing time, making it practical. Moreover, since one adhesive liquid is divided into multiple parts, the reaction and curing with the other adhesive liquid poured out from the outer nozzle can be completely cured without leaving any uncured parts. It can be carried out.
