Claims (1)

Способ получения отвердителей эпоксидных смол холодного отверждения, включающий операции смешения ароматического и алифатического ди- или полиаминов и введения салициловой кислоты, отличающийся тем, что предварительно получают продукт взаимодействия ароматического ди- или полиамина (А) с салициловой кислотой (Б), растворенной в продукте этерификации орто-фталевой кислоты и гидроксилсодержащего соединения(В), путем перемешивания компонентов в реакторе при температуре 50+90oС в течение 6+40 мин в соотношении А: Б: В от, 98: 1: 1 до 10: 20: 70, в другом реакторе предварительно получают продукт взаимодействия алифатического ди-или полиамина (Г) с теми же компонентами путем перемешивания их при температуре 30+55oС в течение 3+25 мин в соотношении Г: Б: В от 96: 2: 2 до 4: 16: 80, после чего полученные продукты взаимодействия на основе ароматического и алифатического ди- или полиаминов смешивают при температуре 15+60oС в течение 3+20 мин в соотношении от 95: 5 до 5: 95.A method of producing hardeners of cold cured epoxy resins, including the steps of mixing aromatic and aliphatic di or polyamines and introducing salicylic acid, characterized in that the product of the interaction of aromatic di or polyamine (A) with salicylic acid (B) dissolved in the esterification product is preliminarily obtained orthophthalic acid and hydroxyl-containing compound (B), by mixing the components in the reactor at a temperature of 50 + 90 o C for 6 + 40 min in a ratio of A: B: C from, 98: 1: 1 to 10: 20: 70, in another reactor previously prepared reaction product of an aliphatic di-or polyamine (F) with the same components by mixing them at a temperature of 30 + 55 o C for 3 +25 min at a ratio of T: P: B of 96: 2: 2 to 4: 16 : 80, after which the obtained reaction products based on aromatic and aliphatic di- or polyamines are mixed at a temperature of 15 + 60 o C for 3 + 20 min in a ratio of 95: 5 to 5: 95.
