Description

Предлагаетс  способ придани  водостойкости термостойким издели м из вермикулита, шлаковой ваты и т. п. материалов иа глииистоп св зке, при котором отформованные и высушенные издели  пропитывают полимерами кремниевой кислоты или гидратами их, содержащимис  в кубовых остатках от ректификации эфиров кремнекислоты. Подобна  пропитка образовывает в массе изделий стойкие к воде соединени . Кремний в кубовых остатках находитс  в виде полимерных соединений , например в виде димеров (КОз)5Ю - Si(OR)3, и в виде продуктов гидролиза таких полимеров.A method is proposed for imparting water resistance to heat-resistant articles made of vermiculite, slag wool, etc., of a glue-stitching material, in which molded and dried products are impregnated with silicic acid polymers or hydrates contained in the bottoms from the rectification of silica esters. Similar impregnation forms water-resistant compounds in the mass of products. Silicon in bottoms is in the form of polymeric compounds, for example, in the form of dimers (CO3) 5U — Si (OR) 3, and in the form of hydrolysis products of such polymers.

В кубовых остатках содержание этих соединений составл ет выше 90% и определ етс  обш,им содержанием Si02, количество кото1)ой доходит до 40%.In bottoms, the content of these compounds is above 90% and is determined by the content of SiO2, the amount of which is up to 40%.

В состав кубовых остатков вход т также эфиры, спирты, соли металлов , разные загр знени , в общем количестве менее 10%.The residues also include esters, alcohols, metal salts, various contaminants, in total less than 10%.

В .массе отформованных или высушенных изделий нз вермикулита, шлаковой ваты и т. п. материалов, изготовленных на глинистой св зке, при пропитывании вышеуказанными полимерами кремниевой кислоты или их гидратами образуютс  соединени , стойкие к воздействию воды, благодар  чему повышаетс  водостойкость изделий.In the mass of molded or dried products using vermiculite, slag wool, etc., materials made on a clay bond, when impregnated with the above silicic acid polymers or their hydrates, water resistant compounds are formed, thereby increasing the water resistance of the products.
