Obtaning the new heat-resistant epoxy composition based on ED-20 epoxy resin

In order to create new heat-resistant epoxy compositions based on ED-20 epoxy resin, triglyceride 1,2,3-tricarboxymethylimide of saccharin-6-carboxylic acid has been synthesized. The interaction reaction of triglyceride of saccharin-6-carboxylic acid with monochloroacetic acid was carried out. The composition and structure of the synthesized compound have been confirmed by data elemental analysis and IR-spectroscopy. The obtained product was used as a curing agent-plasticizer for industrial epoxy resin ED-20. For a comparative estimation of the thermal indices of the obtained epoxy composition, the structure of the composition of ED-20 + PEPA was also prepared. The optimal amount of hardener was selected by the method of thermogravimetry based on weight loss. It has been established that the obtained compound cures ED-20 epoxy resin under had temperature conditions, but when use of UP 606/2 curing accelerator, the curing temperature of the composition decreased. Thermal properties were determined by DTA and TGA methods, and some physical and mechanical properties of epoxy compositions were also studied. It is shown that the obtained epoxy compositions have high thermal and physical-mechanical properties, which leads to the conclusion that the synthesized compound can be successfully used as a highly effective curing agent-plasticizer for ED-20 epoxy resin.
