Изобретение относится к области получения пенополиуретанов, в частности , пенополииэопиануратов, и может быть использовано в различных областях промышленности.The invention relates to the field of production of polyurethane foams, in particular, foamed eopianurates, and can be used in various industries.
Известен способ получения пенополиуретанизопиануратов путем взаимодействия избытка полиизонианата с полиолом в присутствии катализатора тримериза— пни [1].There is a method of producing polyurethane foam isopanurates by reacting an excess of polyisonianate with a polyol in the presence of a trimeriz catalyst — stumps [1].
Недостатком известного способа явля—< ется то, что значительная часть дорогостоящего полиизонианата, вступающего в реакцию, используется для создания изоциануратных колец.A disadvantage of the known method is that a significant part of the expensive polyisonianate entering into the reaction is used to create isocyanurate rings.
Наиболее близким к предложенному по технической сущности является способ получения пенополиуретаниэопианурата ι путем вэаимодействия изоцианатного компонента с полиолом в присутствии вспенивающего агента и катализатора £ 2].Closest to the proposed technical essence is a method for producing polyurethane eryopianurate ι by reacting an isocyanate component with a polyol in the presence of a blowing agent and a catalyst £ 2].
Однако согласно известному способу для получения иэопиануратных колец попользуют полиолы, содержащие изопиану* ратные кольца, например трио-( 2-оксиэтил)-изопианурата. Однако такие соединения имеют температуру плавления выше 100° С и, следовательно, с трудом под5 даются обработке. Λ However, according to the known method, polyols containing isopianate * rings, for example trio (2-hydroxyethyl) -isopianurate, are used to obtain iepianurate rings. However, such compounds have a melting point above 100 ° C and, therefore, are difficult to process. Λ
Целью изобретения является повыше** , ние качества получаемого продукта.The aim of the invention is to improve ** the quality of the resulting product.
Указанная цель достигается тем, что согласно способу получения пенополи' уретанизопианурата путем взаимодействия изоцианатного компонента с полиолом в присутствии вспенивающего агента и катализатора в качестве полиола используют соединение, выбранное из группы, включающей трио-оксиметилизопианурат, оксиметилизопианурат, оксиметилоксипропнлиэоцианурат, оксиметил-2-оксипропилизопианурат.This goal is achieved by the fact that according to the method for producing polyurethane urethaneisopianurate foam by reacting an isocyanate component with a polyol in the presence of a blowing agent and a catalyst, a compound selected from the group consisting of trio-oxymethylisopianurate, oxymethylisopianurate, oxymethyloxypropnlieocyanurate-2-hydroxymethylene is used as a polyol.
Предложенный споооб осуществляют в присутствии катализатора, ускоряющего реакцию между изоцианатными и гидроксильными группами, а также в присутствии, в случае необходимости, растворителя или смеси растворителей.The proposed spooob is carried out in the presence of a catalyst accelerating the reaction between isocyanate and hydroxyl groups, as well as in the presence, if necessary, of a solvent or mixture of solvents.
