PRINTHEAD HAVING TWO ADHESIVES

PROBLEM TO BE SOLVED: To provide a printhead assembly which uses cross-linkable acrylic adhesives to improve the bonding of adjacent layers in a jetstack and reduce the size of a printhead while mitigating degradation of internal printhead components due to environmental stresses.SOLUTION: The print...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a printhead assembly which uses cross-linkable acrylic adhesives to improve the bonding of adjacent layers in a jetstack and reduce the size of a printhead while mitigating degradation of internal printhead components due to environmental stresses.SOLUTION: The printhead assembly includes a first plate and a second plate stacked together. The printhead assembly includes a first adhesive 21 between the first plate and the second plate for bonding the plates together. The printhead assembly includes a second adhesive 22 surrounding an outer edge of the first adhesive wherein the second adhesive 22 has an oxygen migration rate lower than an oxygen migration rate of the first adhesive 21. An oxygen sensitive component is contained within the outer edge of the first adhesive 21. 【課題】架橋可能なアクリル系接着剤を使用して、環境ストレスに起因した印刷ヘッド要素内部での分解を軽減しつつ、ジェットスタックに隣接する層の結合を高め、印刷ヘッドのサイズを小さくした、印刷ヘッドアセンブリを提供する。【解決手段】印刷ヘッドアセンブリは、一緒に積み重ねられた第１のプレートおよび第２のプレートを含む。印刷ヘッドアセンブリは、第１のプレートと第２のプレートを一緒に結合するために、第１のプレートと第２のプレートとの間に第１の接着剤２１を含む。印刷ヘッドアセンブリは、第１の接着剤２１の外側の縁の周囲にある第２の接着剤２２を含み、第２の接着剤２２は、第１の接着剤２１よりも酸素移動速度が遅い。酸素感受性成分は、第１の接着剤２１の外側の縁の中に含まれる。【選択図】図３
