Abstract

Способ получения отвердителей эпоксидных смол, включающий операцию взаимодействия ди- или полиэпоксидных соединений с азотосодержащими компонентами, отличающийся тем, что в качестве азотосодержащего компонента (А) применяют соединения, имеющие в своей структуре один или несколько третичных атомов азота и одновременно одну или несколько функциональных групп -NCO, -СООН, -ОН и осуществляют взаимодействие с ди- и полиэпоксидными соединениями (Б) путем их перемешивания при температурах от 60- до 220°С в течение от 10 до 150 мин при соотношении А:Б от 20:80 до 90:10, после чего синтезированный продукт (В) смешивают с аддуктом, ароматического или алифатического амина с эпоксидной смолой, полученным при избытке амина от 6 до 20 от стехиометрического количества (Г) в соотношении В:Г от 5:95 до 95:5A method for producing hardeners of epoxy resins, including the operation of the interaction of di- or polyepoxide compounds with nitrogen-containing components, characterized in that as the nitrogen-containing component (A), compounds are used that have one or more tertiary nitrogen atoms and one or more functional groups in their structure - NCO, —COOH, —OH and interact with the di- and polyepoxide compounds (B) by mixing them at temperatures from 60- to 220 ° C for 10 to 150 minutes at a ratio of A: B about 20:80 to 90:10, after which the synthesized product (B) is mixed with an adduct of an aromatic or aliphatic amine with an epoxy resin obtained with an excess of amine from 6 to 20 of the stoichiometric amount (G) in the ratio B: G from 5:95 up to 95: 5
