The present invention provides a composition comprising
a) at least one epoxy resin,
b) at least one cyclic amine of the formula (I)
in which
R1 to R4 is H or an organic radical and
X═—(Y1)m-(A1)n-(Y2)o-(A2)p-(Y3)q-(A3)r-(Y4)s—, (II)
where, independently of one another,
m, n, o, p, q, r and s=0 or 1,
A1, A2, A3=alkylene or alkenylene radical and
Y1, Y2, Y3, Y4=NR5, PR5, O or S, where R5 independently=organic radical,
where any two organic radicals selected from R1 to R5 and any radicals present in the alkylene and/or alkenylene radicals A1, A2, A3 may also form one or more further rings,
with the proviso that at least one of the radicals selected from R1 to R5 present and any radicals present in the alkylene and/or alkenylene radicals A1, A2, A3 is substituted by at least one —NHR6 or —NH2 group, where R6=organic radical, and
c) at least one salt of a very strong Brønsted acid with a counterion selected from metal ions, metal-containing ions, phosphonium ions and unsubstituted ammonium ions,
and to processes for production thereof and use thereof.
本发明提供了一种组合物,其中包括
a) 至少一种环氧树脂、
b) 至少一种式 (I) 的环胺
其中
R1 至 R4 是 H 或有机基,以及
X═-(Y1)m-(A1)n-(Y2)o-(A2)p-(Y3)q-(A3)r-(Y4)s-, (II)
其中
m、n、o、p、q、r 和 s=0 或 1、
A1、A2、A3=亚烷基或烯基且
Y1、Y2、Y3、Y4=NR5、PR5、O 或 S,其中 R5 独立地=有机基、
其中选自 R1 至 R5 的任意两个有机基和亚烷基和/或烯基中的任意基 A1、A2、A3 还可形成一个或多个环、
但至少有一个选自 R1 至 R5 的基和亚烷基和/或烯基 A1、A2、A3 中的任何基被至少一个 -NHR6 或 -NH2 基团取代,其中 R6=有机基,以及
c) 至少一种非常强的布氏酸与选自金属离子、含金属离子、鏻离子和未取代铵离子的反离子的盐、
及其生产工艺和用途。
