Abstract
Description
Изобретение относится к способам получения отвердителей оптически прозрачных эпоксидных композиций. The invention relates to methods for producing hardeners of optically transparent epoxy compositions.
Цель изобретения - повышение теплостойкости отвержденных эпоксидных композиций. The purpose of the invention is to increase the heat resistance of cured epoxy compositions.
П р и м е р 1. 97,0 г (1 моль) диэтилентриамина, 90,0 г (0,45 моль) глицидилового эфира 1-нафтола, 90,2 г (0,55 моль) крезилглицидилового эфира перемешивают при 27 ± 2оС в течение 1,5 ч и зачем при 35 ± 3оС в течение 2,5 ч.Example 1. 97.0 g (1 mol) of diethylene triamine, 90.0 g (0.45 mol) of 1-naphthol glycidyl ether, 90.2 g (0.55 mol) of cresyl glycidyl ether are stirred at 27 ± 2 ° C for 1.5 hours and why at 35 ± 3 ° C for 2.5 hours.
П р и м е р ы 2-9. Аналогичны примеру 1. PRI me R s 2-9. Similar to example 1.
Соотношение компонентов и свойства отвердителей представлены в табл. 1. The ratio of components and properties of hardeners are presented in table. 1.
Эпоксидные композиции готовят смешением диглицидилового эфира D,L-камфарной кислоты (ДГЭКК), диглицидилового эфира метилтетрагидрофталевой кислоты (ДГЭФК) или диглицидилового эфира дифенилолпропана (ДГЭДП) с отвердителями по примерам 1-9 в количестве, указанном в табл. 1. Бесцветные прозрачные композиции отверждают при 20-100оС. Свойства отвержденных при 80оС в течение 20 ч композиций представлены в табл. 2 и 3.Epoxy compositions are prepared by mixing diglycidyl ether of D, L-camphoric acid (DHECC), diglycidyl ether of methyltetrahydrophthalic acid (DHEF) or diglycidyl ether of diphenylol propane (DHEDP) with hardeners according to examples 1-9 in the amount indicated in the table. 1. Colorless transparent composition is cured at 20-100 ° C. The properties of the cured at 80 ° C for 20 hours, the compositions are presented in Table. 2 and 3.
