Description

Изобретение относитс к составам строительных растворов, содержащих химические добавки.This invention relates to compositions of building solutions containing chemical additives.
Известно вспенивающее действие соединений , содержащих изоцианатные группы.The foaming effect of compounds containing isocyanate groups is known.
Цель изобретени - ускорение твердени строительного раствора.The purpose of the invention is to accelerate the curing of mortar.
Это достигаетс тем, что в качестве органической добавки раствор содержит соединени , содержащие изоцианатные группы в количестве 7,25-50% от веса твердых составл ющих .This is achieved by the fact that, as an organic additive, the solution contains compounds containing isocyanate groups in the amount of 7.25-50% by weight of the solid constituents.
Предусматриваетс вводить кремнеземистый компонент в строительный раствор в измельченном виде с размером частиц от 0,076 жлг до 38,1 мм.It is envisaged to introduce the silica component into the mortar in a ground form with a particle size of from 0.076 g to 38.1 mm.
В качестве органических соединений, содержащих изоцианатные группы, используют диизоцианат толуола, диизоцианат дифенилметана , а также их уретедионовые или изоциануратные полимеры и полиуретаны с концевыми изоцианатными группами.As organic compounds containing isocyanate groups, toluene diisocyanate, diphenylmethane diisocyanate, as well as their uretedionic or isocyanurate polymers and polyurethanes with terminal isocyanate groups are used.
Предлагаема добавка может быть при необходимости предварительно объединена с растворителем.The proposed additive can be optionally pre-combined with a solvent.
Способ приготовлени композиции заключаетс в том, что предварительно портландцемент смещивают с органической добавкой, а затем в полученную смесь ввод т песок и воду.The method of preparation of the composition is that the pre-Portland cement is shifted with an organic additive, and then sand and water are introduced into the resulting mixture.
Полученную композицию используют, например , дл покрыти полов.The resulting composition is used, for example, for flooring.
