摘要: Epoxy resin compositions are cured with mixtures of di-primary amines and carbamates, which are the reaction products of di-primary amines with alkylene glycol carbonates. The mixtures lead to faster curing, giving cured resins with improved properties, than may be observed after curing with di-primary amines alone.
Preferred di-primary amines are ethylene amines, oxyalkylene amines, cycloaliphatic or araliphatic amines or alkylene diamines. Preferred carbonates are ethylene or propylene glycol carbonate.摘要翻译: 环氧树脂组合物用二伯胺和氨基甲酸酯的混合物固化,二胺和氨基甲酸酯是二 - 伯胺与亚烷基二醇碳酸酯的反应产物。 混合物导致更快的固化,给予固化树脂具有改善的性能,比单独用二胺固化后可观察到。 优选的二伯胺是亚乙基胺,氧化烯胺,脂环族或芳脂族胺或亚烷基二胺。 优选的碳酸酯是乙烯或丙二醇碳酸酯。

摘要: Epoxy resin composition comprising a vicinal polyepoxide having an average of at least 1.8 reactive 1,2-epoxy groups per molecule, can be cured by an isophthalamido amine curing agent having the formula:
C₆H₄(CONH-R¹-CH₂CH₂NH₂)₂
wherein C6₂H₄ is meta -phenylene, and R¹ is an oxyethylene group of the formula:
-(CH₂CH₂O) x -
wherein x is 1 to 3.
In a preferred embodiment, the curing agent may be used with a co=curng agent having the formula:
H₂N-R²-CH₂CH₂NH₂
wherein R has the formula:
-(CH₂CH₂O) x -
wherein x is 1 to 3 or the formula:摘要翻译: 包含每分子平均具有至少1.8个反应性1,2-环氧基团的连位聚环氧化物的环氧树脂组合物可以通过具有下式的间苯二酰胺胺固化剂固化:C 6 H 4(CONH-R 1 -CH 2 CH 2 NH 2)2其中C 6 H 4是元 - 亚苯基,而R 1是式 - (CH 2 CH 2 O)x - 的氧亚乙基,其中x是1-3。在一个优选的实施方案中,固化剂可以与具有下式的助剂一起使用:H 2 N-R 2 -CH 2 CH 2 NH 2其中R具有下式: - (CH 2 CH 2 O)x - 其中x是1至3或下式:
