Description
(54) СПОСОБ ОБРАБОТКИ ИЗДЕЛИЙ(54) METHOD FOR PROCESSING PRODUCTS
Изобретение относитс к технологии нанесени гидрофобных покрытий на издели из стекла, керамики и других материалов, примен емых в различных област х техники, например , в химической, медицинской, фармацевтической промышлепност х.The invention relates to the technology of applying hydrophobic coatings on products made of glass, ceramics and other materials used in various fields of technology, for example, in the chemical, medical, pharmaceutical industries.
Известны способы придани гидрофобных свойств стеклу и другим материалам путем обработки их поверхности полиорганосилоксанами .Methods are known for imparting hydrophobic properties to glass and other materials by treating their surface with polyorganosiloxanes.
Силоксановые нокрыти из растворов или эмульсий, нанесенные на стекл нные или другие издели , придают последним гидрофобные свойства.Siloxane coatings from solutions or emulsions applied to glass or other products give the latter hydrophobic properties.
Недостатком способ обработки изделий силанами или силоксанами вл етс мала устойчивость покрытий к воздействию воды и различных агрессивных сред, например концентрированных кислот, органических растворителей и растворов солей.The disadvantage of the method of processing products with silanes or siloxanes is the low resistance of coatings to water and various aggressive media, such as concentrated acids, organic solvents and salt solutions.
Целью изобретени вл етс повышение химической стойкости, гидрофобности при сохранении прозрачности в видимой области спектра покрытий по стеклу, керамике и другим материалам .The aim of the invention is to increase the chemical resistance, hydrophobicity while maintaining transparency in the visible region of the spectrum of coatings on glass, ceramics and other materials.
Это достигаетс тем, что на поверхность издели нанос т полисилоксаи, нолуче шый взаимодействием а, о)-дигидроксиполи-(метил-3, 3,3-трифторпропил)силоксана с метилтриацетоксилоксаном в среде сухого растворител .This is achieved by polysiloxai applied on the surface of the product, but best interaction of a, o) -dihydroxypoly- (methyl-3, 3,3-trifluoropropyl) siloxane with methyl triacetoxyloxane in a dry solvent.
осуществл ют термообработку при 120-160°С, а после охлаждени поверхность издели дополнительно обрабатывают концентрированной уксусной кислотой.heat treatment is carried out at 120-160 ° C, and after cooling, the surface of the product is further treated with concentrated acetic acid.
Дл осуществлени предлагаемого способа а ,со-дигидроксиполи-(метил-3, 3,3-трифторпропил )силоксаны, имеющие в зкость от 8 до 16 пуаз раствор ют в сухом этилацетате. К полученному 5-10%-ному раствору полимераIn order to carry out the proposed process, a, co-dihydroxypoly- (methyl-3, 3,3-trifluoropropyl) siloxanes having a viscosity of from 8 to 16 poises are dissolved in dry ethyl acetate. To the resulting 5-10% polymer solution
добавл ют при перемешивании метилтриацетоксисилап в количестве 5% от веса полимера. Обработку изделий производ т любым способом - окунанием, распылением и т. д. После испарени растворител обработанные издели прогревают в течение 2-3 час при 120-160°С.with stirring, methyltriacetoxysilap is added in an amount of 5% by weight of the polymer. The products are processed by any method - dipping, spraying, etc. After evaporation of the solvent, the processed products are heated for 2-3 hours at 120-160 ° C.
Дл улучшени гидрофобных свойств покрытий издели с нанесенным фторсилоксановым покрытием после отверждени при 120-To improve the hydrophobic properties of coatings of a fluorosiloxane coated product after curing at 120-
160°С и охлаждени до комнатной температуры , погружают в концентрированную уксусную кислоту на 24 час, после чего споласкивают водой.160 ° C and cooling to room temperature, immersed in concentrated acetic acid for 24 hours, then rinsed with water.
Результаты испытаний покрытий в агрессивных средах приведены в таблице.The test results of coatings in aggressive media are shown in the table.
Получаемое покрытие прозрачно в видимой области спектра и остаетс прозрачным в этой области после испытани в вышеуказанных средах.The resulting coating is transparent in the visible region of the spectrum and remains transparent in this region after being tested in the above media.
Таким образом, предложенный способ позвол ет получать гидрофобные покрыти прозрачные в видимой области спектра и устойчивые в течение длительного времени.Thus, the proposed method allows to obtain hydrophobic coatings that are transparent in the visible spectral region and stable for a long time.
Эти свойства покрытий позвол ют примен ть их в издели х медицинской, фармацевтической и других област х техники.These properties of coatings allow them to be used in products of medical, pharmaceutical and other technical fields.
