Abstract

Группа изобретений относится в области химии высокомолекулярных соединений, преимущественно к технологии получения пенополиуретанов, а конкретнее к составу однокомпонентной пены с низким содержанием мономерного диизоцианата (2,2'-метилендифенилизоцианата, 2,4'-метилендифенилизоцианата и 4,4'-метилендифенилизоцианата), и способу приготовления однокомпонентной полиуретановой пены с использованием указанного состава. Первым объектом группы изобретений является смесь однокомпонентных изоцианатных преполимеров для приготовления полиуретанового продукта за одноступенчатый процесс, где содержимое мономерного метилендифенилдиизоцианата (МДИ) в названной смеси не превышает 3%, в предпочтительном случае составляет менее 2%, а в оптимальном случае менее 1% от общей массы, содержащая монофункциональный спирт, изоцианатный компонент или смесь изоцианатных компонентов, пропеллент, катализатор, стабилизатор, один или несколько полиолов. Монофункциональный спирт представляет собой эфиры этиленгликоля или эфиры пропиленгликоля, а также способ приготовления однокомпонентной полиуретановой пены на основе названной смеси. Вторым объектом группы изобретений является способ приготовления однокомпонентной полиуретановой пены, характеризующейся тем, что он содержит следующие этапы: подготавливается дозирующий контейнер, в контейнер транспортируется смесь, определенная в одном из пп.1-7 формулы, предпочтительно таким образом, чтобы пропеллент оставался за пределами контейнера, дозирующий контейнер закрывают, в предпочтительном случае пропеллент подают в контейнер.
