(54) СПОСОБ ПОЛУЧЕНИЯ ПОКРЫТИЯ(54) METHOD OF COATING
1one
Изобретение относитс к способу получени полимерных защитных покрытий, преимущественно армированных стеклотканью, используемых в качестве теплоизол ции от воздействи влаги.The invention relates to a method for producing polymeric protective coatings, predominantly glass fiber reinforced, used as thermal insulation against moisture.
Известен способ получени покрыти , армированного стеклотканью, согласно которому на стеклоткань нанос т несколько слоев из композиции на основе полиметилфенилсилоксановой смолы, толуола и минеральных добавок с последующей сушкой при комнатной температуре 1 .A known method for producing a glass-fiber-reinforced coating, according to which several layers of a composition based on polymethylphenylsiloxane resin, toluene and mineral additives are applied onto the glass fabric, followed by drying at room temperature 1.
Полученные покрыти способны длительное врем работать при температуре до 300С. Однако они не обладают эластичностью , после изготовлени и выдержки на воздухе в течение 3-4 дней при 18-20С станов тс хрупкими, при изгибах нарушаетс целостность поверхностного сло .The resulting coatings can operate for a long time at temperatures up to 300 ° C. However, they do not have elasticity; after production and exposure to air for 3-4 days at 18-20 ° C, they become brittle; during bending, the integrity of the surface layer is disturbed.
С целью получени покрыти , длительное врем сохран ющего эластичность, на стеклоткань предварительно нанос т один или два сло указанной композиции, содержащей дополнительно этилсиликат в количестве 10-30% от веса композиции.In order to obtain a coating with a long time of preserving elasticity, one or two layers of this composition, containing additionally ethyl silicate in an amount of 10-30% by weight of the composition, are preliminarily applied to the glass fabric.
Полученное покрытие, содержащее два первых сло с этилсиликатом,сохран ет эластичность не менее 4 мес, а содержащее только один указанный слой -2 мес.The resulting coating, containing the first two layers of ethyl silicate, retains its elasticity for at least 4 months, and containing only one specified layer, -2 months.
Покрытие, у которого все слои или три сло получены на основе композиции, содержащей этилсиликат, обладают липкостью.A coating in which all layers or three layers are obtained on the basis of a composition containing ethyl silicate is tacky.
Пример 1. Готов т композицию на основе полиметилфенилсилоксановой смолы, толуола и минеральных добавок (асбест, слюда и другие), имеющую сухой остаток 55%, и на 100 вес. ч. указанной смеси добавл ют 20 вес. ч. этилсиликата. Смесь тщательноExample 1. A composition based on a polymethylphenylsiloxane resin, toluene and mineral additives (asbestos, mica, and others), having a dry residue of 55%, and per 100 wt. including this mixture add 20 weight. including ethyl silicate. Blend thoroughly
перемешивают и довод т толуолом до в зкости 20 с по вискозиметру ВЗ-4 при 1820 С. Полученную композицию нанос т на стеклоткань и сушат 2 ч при комнатной температуре . Затем готов т состав из указанных выше компонентов, но без этилсиликата и нанос т дополнительно два сло из этой композиции с промежуточной сушкой. Покрытие выдерживают при 18-20 С 6-8 дней. Пример 2. Готов т композицию, как указано в примере 1, содержащую 30 вес. ч.mixed and adjusted with toluene to a viscosity of 20 s according to a VZ-4 viscometer at 1820 C. The resulting composition is applied to glass cloth and dried for 2 hours at room temperature. Then the composition of the above components is prepared, but without ethyl silicate, and an additional two layers of this composition are applied with intermediate drying. The coating is maintained at 18-20 C for 6-8 days. Example 2. Preparing a composition as indicated in example 1, containing 30 wt. h
