Description
Дл отверждени эпоксидных смол в промышленности примен ютс гексаметилендиамин, полиэтиленполиамин и другие амины. Однако полиэтиленполиамин дорогой, нестандартный и остродефицитный продукт, а использование гексаметилендиамина сопр жено с р дом трудностей, так как он при комнатной температуре очень гигроскопичен и жадно поглощает из воздуха углекислоту, кроме того, он вл етс сильно токсичным веществом. Применение спиртового раствора гексаметилендиамина устран ет перечисленные недостатки, но не позвол ет получать качественных заливок.Hexamethylenediamine, polyethylene polyamine and other amines are used in industry for curing epoxy resins. However, polyethylenepolyamine is an expensive, non-standard and extremely scarce product, and the use of hexamethylenediamine poses a number of difficulties, since it is very hygroscopic at room temperature and greedily absorbs carbon dioxide from the air, and it is also a highly toxic substance. The use of an alcoholic solution of hexamethylenediamine eliminates the above disadvantages, but does not allow to obtain high-quality fillings.
В описываемом способе предлагаетс проводить отверждение эпоксидных смол гексаметиленимином или его смесью с гексаметилендиамином . Предлагаемые отвердители дают возможность улучшить технологический процесс и получать заливки , не отличающиес по своим свойствам от эпоксидных смол, отвержденных гексаметиленд и амином.In the described method, it is proposed to cure epoxy resins with hexamethyleneimine or its mixture with hexamethylenediamine. The proposed hardeners provide an opportunity to improve the technological process and to obtain castings, not differing in their properties from epoxy resins, hardened with hexamethylene and amine.
Кррме того, они малогигроскопичны , менее токсичны и более устойчивы при хранении, чем гексаметилендиамин .In addition, they are less hygroscopic, less toxic and more stable during storage than hexamethylenediamine.
Пример. На 100 вес. ч. эпоксидной смолы ЭД-6 берут 7,5 вес. ч. гексаметиленимина и провод т отверждение при комнатной температуре с последующей термообработкой при 60° в течение б час.Example. 100 weight. including epoxy resin ED-6 take 7.5 weight. including hexamethylenimine and cured at room temperature, followed by heat treatment at 60 ° for bh.
Отвержденна эпоксидна смола имеет следующие показатели: удельна ударна в зкость 12- 13 кгсм/см ; предел прочности при статическом сгибе 950-900 кг/кг ; теплостойкость по Мартенсу 70°; твердость по Бринеллю 21 - 22 кг/мм.The cured epoxy resin has the following characteristics: specific impact viscosity 12-13 kgcm / cm; tensile strength at static fold 950-900 kg / kg; heat resistance according to Martens 70 °; Brinell hardness 21–22 kg / mm.
Предмет изобретени Subject invention
Способ отверждени эпоксидных смол, отличающийс тем, что, с целью улучщени технологического процесса, в качестве отвердител примен ютс гексаметиленимин или его смеси с гексаметилендиамином .A method of curing epoxy resins, characterized in that, in order to improve the technological process, hexamethylenimine or its mixture with hexamethylenediamine is used as a hardener.
