Disclosed is a moisture-curing type curable resin composition containing: a curable resin intramolecularly having a silicon-containing functional group; and a Lewis acid or a complex of the Lewis acid as a curing catalyst, the Lewis acid being selected from the group consisting of metal halides and boron halides, which is rapidly cured at room temperature. The silicon-containing functional group is represented by general formula: —SiX

, the curable resin further contains intramolecularly a polar component that is one of urethane, thiourethane, urea, thiourea, substituted urea, substituted thiourea, amide, and sulfide bonds, and hydroxyl, secondary amino and tertiary amino groups. Two-part type adhesive is constitutible with separating the curable resin from the curing catalyst.
本发明公开了一种含有湿气硬化型可硬化树脂组分,包括:具有含硅官能团的可硬化树脂分子内部;以及一种Lewis酸或Lewis酸的复合物作为固化催化剂,所述Lewis酸选自金属卤化物和硼卤化物组成的群体,该组分在室温下迅速固化。所述含硅官能团由下式表示:—SiX1X2X3或—SiR1X1X2(其中,X1、X2和X3分别表示水解基团,可以相同也可以不同,R1表示具有1到20个碳的取代或未取代的有机基团)。如果所述含硅官能团为—SiR1X1X2,则可硬化树脂还包括分子内部的极性成分,该极性成分是尿素、硫脲、脲、硫代脲、取代脲、取代硫脲、酰胺和硫化物键以及羟基、二级胺和三级胺基之一。两部分型粘合剂可通过将可硬化树脂与固化催化剂分离而形成。
