摘要： A storage-stable suspension of an epoxy resin hardener and a toughener useful as a molding composition is prepared via a) the addition of an organic solvent to an aqueous emulsion of the toughener when using a water-sensitive hardener, such as a polycarboxylic anhydride, removing the water as an azeotrope by vacuum distillation, then adding the epoxy resin hardener and removing the residual solvent by vacuum distillation, or b) the addition of an aqueous emulsion of the toughener with or without an organic solvent to the epoxy resin hardener when using a water-insensitive hardener such as a polyamine, and removing the water and any organic solvent by vacuum distillation.
摘要翻译：通过以下步骤制备环氧树脂固化剂和用作模塑组合物的增韧剂的储存稳定的悬浮液：a）当使用水溶性硬化剂如多元羧酸酐时，将有机溶剂加入到增韧剂的水性乳液中，通过真空蒸馏除去作为共沸物的水，然后加入环氧树脂固化剂并通过真空蒸馏除去残留溶剂，或b）当使用或不使用有机溶剂时，将有机溶剂的增韧剂水性乳液加入到环氧树脂固化剂中不溶于水的固化剂如多胺，并通过真空蒸馏除去水和任何有机溶剂。
