Description
即ち、本発明は、イソシアネート基含有ホットメルトウレタンプレポリマー（Ａ）と、酸性リン酸エステル（Ｂ）と、エポキシ基を有するシランカップリング剤（ｃ−１）及びメルカプト基を有するシランカップリング剤（ｃ−２）からなる群より選ばれる少なくとも１種のシランカップリング剤（Ｃ）とを含有してなり、前記ホットメルトウレタンプレポリマー（Ａ）がポリオールとポリイソシアネートとを反応させて得られ、前記ポリオールの少なくとも２０重量％がポリエステルポリオールであるとともに、前記酸性リン酸エステル（Ｂ）が、炭素原子数１〜４の範囲のアルキル基を有するリン酸モノアルキルエステル及びリン酸ジアルキルエステルからなる群より選ばれる少なくとも１種である湿気硬化性ホットメルト接着剤を提供するものである。 That is, the present invention relates to an isocyanate group-containing hot melt urethane prepolymer (A), an acidic phosphate ester (B), an epoxy group-containing silane coupling agent (c-1), and a mercapto group-containing silane coupling agent. It contains at least one silane coupling agent (C) selected from the group consisting of (c-2), and the hot melt urethane prepolymer (A) is obtained by reacting a polyol and a polyisocyanate. , together with the least 20 wt percent of the polyol is a polyester polyol, the acid phosphoric acid ester (B) is phosphoric acid monoalkyl esters and dialkyl phosphate having an alkyl group ranging from 1 to 4 carbon atoms providing moisture-curing hot-melt adhesive is at least one selected from the group consisting of Is shall.
まず、本発明で使用するイソシアネート基含有ホットメルトウレタンプレポリマー（Ａ）について説明する。
当該ウレタンプレポリマー（Ａ）は、常温で固体又は粘稠な性状を有するものであり、ポリエステルポリオールを少なくとも２０重量％を含むポリオールと、ポリイソシアネートとを反応させて得られるものである。
First, the isocyanate group-containing hot melt urethane prepolymer (A) used in the present invention will be described.
The urethane prepolymer (A) are those having a solid or viscous nature at room temperature, it is obtained by reacting a polyol containing 20 weight percent and less polyester polyol, and a polyisocyanate.
