Изобретение относитс к промышленности строительных материалов и строительной индустрии и может быть применено при формовании строительных изделий на основе гипсовых и других в жущих в резиновых формах.The invention relates to the building materials industry and the building industry and can be applied in the molding of building products based on plaster and others in rubber molds.
Цель изобретени - повышение качества поверхности издели и удлинение срока службы резиновых форм.The purpose of the invention is to improve the quality of the product surface and lengthen the life of rubber forms.
Смазка дл резиновых форм включает водный раствор алю.мометилсиликоната натри , полиметилсилоксановую жидкость и воду при следующем соотношении компонентов , мас.%:Lubricant for rubber forms includes an aqueous solution of sodium alumomethylsiliconate, polymethylsiloxane liquid and water in the following ratio, wt.%:

Водный раствор алюмометилсиликоната натри АМСР-3 содержит в своем составе кремни 7,2% и алюмини 2,4%. Щелочность жидкости (в пересчете на NaOH) составл ет 7,5%.An aqueous solution of alumomethylsiliconate sodium AMCP-3 contains in its composition silicon 7.2% and aluminum 2.4%. The alkalinity of the liquid (in terms of NaOH) is 7.5%.

ПМС-200 представл ет собой смесь полимеров линейной и разветвленной структуры, содержит кремни 37,8% и воды 0,003% ПМС-200 характеризуетс плотностью 0,96 г/см и кинематической в зкостью 198сСт.PMS-200 is a mixture of linear and branched polymers, contains 37.8% silicon and 0.003% PMS-200 water is characterized by a density of 0.96 g / cm and a kinematic viscosity of 198cSt.
Смазку готов т смешиванием в заданном соотношении компонентов при комнатной температуре в течение 3-4 мин до однородного состо ни . Смазку нанос т на резиновые формы кист ми или окунанием при конвейерной технологии производства гипсовых декоративных плит. Затем формы заполн ют гипсовой формовочной смесью и подвергают испытани м.The lubricant is prepared by mixing in a predetermined ratio of components at room temperature for 3-4 minutes until homogeneous. The lubricant is applied to rubber molds by brushing or dipping with the conveyor technology for the production of gypsum decorative plates. The molds are then filled with a plaster molding mixture and subjected to tests.
Примеры составов смазки и результаты испытаний сведены в таблицу.Examples of lubricant compositions and test results are summarized in table.
Как видно из таблицы, прочность сцеплени гипсобетона с резиновой формой в случае применени предлагаемой смазки значительно ниже, чем при использовании извест о ел to As can be seen from the table, the strength of adhesion of gypsum concrete to the rubber form in the case of using the proposed lubricant is much lower than when using known about
ной смазки. При этом предлагаема смазка легче распредел етс равномерным слоем по поверхност м формы, после изготовлени издели имеют более чистые и гладкие с гл нцевым блеском поверхности, а формы не загр зн ютс гипсобетоном. Она не тер ет свои антиадгезионные свойства в течение длительного времени.No grease. At the same time, the proposed lubricant is easier to distribute evenly over the surfaces of the molds, after manufacture, the products have cleaner and smoother surfaces with glossy gloss, and the molds are not contaminated with gypsum concrete. It does not lose its anti-adhesive properties for a long time.
