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度固化型可固化树脂组成物,包括:具有硅含有官能团的可固化树脂分子内部;以及作为固化催化剂的路易斯酸或路易斯酸的复合物,所述路易斯酸选择自金属卤化物和硼卤化物的组中,该组成物在室温下快速固化。硅含有官能团由通式表示:—SiX1X2X3或—SiR1X1X2(其中,X1、X2和X3分别表示一个水解基团,可以相同或不同,R1表示具有1到20个碳的取代或未取代的有机基团)。如果硅含有官能团为—SiR1X1X2,则可固化树脂还包含分子内部的极性组分之一,该极性组分为脲、硫脲、尿素、硫代尿素、取代尿素、取代硫脲、酰胺和硫化物键以及羟基、次级氨基和三级氨基基团。可将可固化树脂与固化催化剂分离以构成两部分型粘合剂。
