Оценка ингибирующего действия некоторых производных солей длинноцепочечных карбоновых кислот по отношению к питтинговой коррозии арматурной стали в бетоне
Аннотация
Синтезированы производные солей длинноцепочечных карбоновых кислот и диметиламинопропиламина, в том числе близких по составу с растительными маслами.
Структура молекул новых веществ надежно подтверждена с применением физических методов ИК-Фурье спектроскопии, ЯМР-спектроскопии и ВЭЖХ. С применением вольтамперометрии проведена оценка ингибирующего действия синтезированных веществ по отношению к арматурной стали марки 35ГС. Эксперименты проводили в водном экстракте из строительного раствора, имитирующем поровую жидкость бетона, в присутствии хлоридов в качестве активаторов питтинговой коррозии, а также в образцах мелкозернистого бетона при периодическом погружении в хлоридный раствор. Обнаружено, что 3-(диметиламино)пропил-1- аммония стеарат не проявляет ингибирующего действия. Введение же солей жирных кислот кокосового и подсолнечного масел увеличивает антикоррозионные свойства. Степень защиты составляет 40-44 % в водных растворах и 30-32 % - для бетонных образцов.
Установлено увеличение времени до начала коррозии в бетонных образцах в 1.75 раза по сравнению с контрольным составом без добавок
