Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: method involves adding a hardener into liquid pre-heated epoxy resin. Further, copper nanoparticles are added to the obtained mixture and the mixture is stirred until a stable suspension is obtained. The obtained suspension is added to an epoxyvinylether resin of a hot hardener and stirred. ^ EFFECT: invention increases fire-resistance of composite materials while preserving mechanical characteristics, physical and mechanical properties and processability during processing via a pultrusion technique. ^ 14 cl, 2 tbl, 3 ex Изобретение относится к способам получения огнестойкого связующего для создаваемых в пултрузионном процессе композиционных материалов и к огнестойкому связующему и изделию. Способ включает введение в жидкую предварительно разогретую эпоксидную смолу отвердителя. Далее загружают в полученную смесь наночастицы меди, перемешивают смесь до получения устойчивой суспензии. Добавляют полученную суспензию в эпоксивинилэфирную смолу горячего отверждения и перемешивают. Изобретение позволяет повысить огнестойкость композиционных материалов при сохранении механических характеристик, физико-химических свойств и технологичности при переработке методом пултрузии. 3 н. и 11 з.п. ф-лы, 2 табл.
