Изобретение касаетс получени эпоксидных композиций дл заливок, пропиток, покрытий , клеев.The invention relates to the preparation of epoxy compositions for castings, impregnations, coatings, adhesives.
Известна эпоксидна полимерна композици , содержаща в качестве отвердител 4,4диаминодифенил метан, анилиноформальдегидную смолу и малеиновый аигидрпд. Недостатками известной композиции вл ютс сравнительно невысокие физико-механические свойства, особенно прочность при раст жении и процепт относительного удлинени , а также экзотермичность процесса отверждени при получении отливок большого веса.A known epoxy polymer composition containing 4,4 diaminodiphenyl methane, aniline formaldehyde resin and maleic acid as a hardener. The disadvantages of the known composition are relatively low physical and mechanical properties, especially tensile strength and relative elongation, as well as the exothermicity of the curing process in the production of high-weight castings.
Цель изобретени - повысить прочность при раст жении, относительное здлинение и другие физико-механические свойства отвержденных композиций, создать возможность получени отливок большого веса, а также расширить сырьевую базу ассортимента нетоксичных и дешевых отвердителей.The purpose of the invention is to increase the tensile strength, relative extension and other physicomechanical properties of hardened compositions, to create the possibility of obtaining heavy castings, and also to expand the raw material base of the range of non-toxic and cheap hardeners.
Эта цель достигаетс применением отвердител , представл юш.его собой смесь 4,4-диамино-2- (метил-/г-аминофенил) дифенилметаиа формулыThis goal is achieved by using a hardener, which is a mixture of 4,4-diamino-2- (methyl- / g-aminophenyl) diphenylmeta
I Н2I H2
И 4,4-диаминодифенилметана, вследствие чего прочность при раст жении композиций повЫшаетс на 23% и относительное удлинение в 2-4 раза.And 4,4-diaminodiphenylmethane, as a result of which the tensile strength of the compositions increases by 23% and the relative elongation by 2-4 times.
Пример 1. К 100 вес. ч. разогретой до 40-50°С эпоксидной диановой смолы марки ЭД-5 с эпоксидным числом 21 приливают 26 вес. ч. расплавленной смеси 4,4-диаминоExample 1. To 100 weight. hours heated to 40-50 ° C epoxy Dianova resin brand ED-5 with an epoxy number of 21 poured 26 weight. including molten mixture of 4,4-diamino
