Claims (1)

Изобретение относится к композиции для получения жестких пенополиуретанов, применяемых в качестве теплоизоляционных материалов в различных областях промышленности, например холодильной, строительной, авиационной и др. Целью изобретения является повышение огнестойкости пенополиуретанов, содержащих уменьшенное вдвое количество озоноопасного фреона-11 при сохранении технологических параметров процесса вспенивания и физико-механических характеристик пенопласта. Композиция для получения жесткого пенополиуретана содержит полиольный компонент, катализатор, пеностабилизатор, воду, вспенивающий агент, полиизоцианат, антипирен, в качестве которого она содержит диметиловый эфир метилфосфоновой кислоты.The invention relates to a composition for producing rigid polyurethane foams used as heat-insulating materials in various industries, for example, refrigeration, construction, aviation, etc. physical and mechanical characteristics of the foam. The composition for producing rigid polyurethane foam contains a polyol as one component, a catalyst, a foam stabilizer, water, a blowing agent, a polyisocyanate, a flame retardant, in which it contains methylphosphonic acid dimethyl ether.
