Description
Изобретение относитс к получению ал- килрезорцинеформальдегидных пенопла- стов, примен емых в качестве теплоизол ционных и/или конструкционных материалов в строительстве.The invention relates to the production of alkylresorcinoldehyde foam plastics used as thermal insulation and / or structural materials in construction.
Цель изобретени - повышение удельной прочности пенопласта при сжатии.The purpose of the invention is to increase the specific strength of the foam during compression.
Композицию дл пенопласта получают следующим образом.The foam composition is prepared as follows.
Алкилрезорциноформальдегидный оли- гомер ФР-100 (ТУ 6-05-1638-78) смешивают с параформом и циклотриметилентринитро- замином в течение 5-7 мин до образовани однородной массы, затем при перемешивании добавл ют40%-ный водный раствор едкого натра. Вспенивание и отверждение пенопласта происходит в течение 5-7 мин.Alkyl resorcinol formaldehyde oligomer FR-100 (TU 6-05-1638-78) is mixed with paraform and cyclotrimethylene centrinitrosmin for 5-7 minutes until it forms a homogeneous mass, then 40% aqueous sodium hydroxide is added with stirring. Foaming and curing of the foam occurs within 5-7 minutes.
Циклотриметилентринитрозамин 1,3,5- тринитрозо-1,3,5-триазоциклогексан получен взаимодействием гексаметилентетра- мина и нитрита натри в кислой среде. Продукт термически устойчив до 120°С, в щелочных растворах разлагаетс с выделением азота.Cyclotrimethylene nitrosamine 1,3,5-trinitroso-1,3,5-triazocyclohexane is obtained by the interaction of hexamethylenetetramine and sodium nitrite in an acidic medium. The product is thermally stable up to 120 ° C, in alkaline solutions it decomposes with evolution of nitrogen.
В табл.1 приведена рецептура композиций дл пенопласта, в табл.2 - свойства пенопласта .Table 1 shows the formulation of the compositions for the foam, in Table 2 the properties of the foam.
