Description
Известен р д способов защиты резиновых изделий от растрескивани под действием озона, например: введение в резиновые смеси веществ, способных мигрировать на поверхность с образованием защитной пленки (парафин, церезин, воск и др.), нанесение таких веществ на поверхность готового издели (так называемое воскование).There are a number of ways to protect rubber products from cracking under the action of ozone, for example: introducing into rubber mixtures substances that can migrate to the surface to form a protective film (paraffin, ceresin, wax, etc.), applying such substances to the surface of the finished product (the so-called waxing).
Предметом данного изобретени вл етс способ защиты резиновых изделий от растрескивани путем создани сжимающих напр жений в поверхностном резиновом слое.The object of this invention is to protect rubber products from cracking by creating compressive stresses in the surface rubber layer.
Дл этого на поверхность вулканизованного полого резинового издели1Я , раст нутого до величины, превышающей его рабочие размеры, нанос т резиновое покрытие из кле или латекса, содержащих ультраускорители . Издели подвулканнзовывают и довод т до нормальных размеров, вследствие чего на его наружной поверхности создаютс сжимающие напр жени .To do this, a rubber coating of glue or latex containing ultra-accelerators is applied to the surface of a vulcanized hollow rubber product, stretched to a size exceeding its working dimensions. The articles are scorched and adjusted to normal size, as a result of which compressive stresses are created on its outer surface.
Поверхность вулканизованных массивных резиновых изделий обрабатывают 75%-ной серной кислотойSurface vulcanized solid rubber products treated with 75% sulfuric acid
и затем подвергают набуханию в триэтаноламине, вследствие чего происходит закрепление набухшего поверхностного резинового сло с созданием сжимающих напр жений.and then is subjected to swelling in triethanolamine, as a result of which the swollen surface rubber layer is consolidated with the creation of compressive stresses.
