METHOD OF OBTAINING COLOURED DECORATIVE COATING ON TECHNICAL FABRIC FOR EXPLOITATION UNDER OUTER SPACE CONDITIONS Russian patent published in 2014 - IPC B05D1/38 

FIELD: chemistry.

SUBSTANCE: in a method of obtaining a coloured decorative coating on a technical fabric for exploitation under outer space conditions, organosilicone thermally stable enamels are used as a paint material. Before the application of layers of the paint material on a technical fabric, fixed on a solid surface, a unilateral background layer of an organosilicone enamel 30-50 mcm thick is applied by means of a pneumatic paint-sprayer with a pressure in the main air supply line of 2-2.2 atm. The background layer is dried at room temperature for not less than two hours. The following parts of the coating with other colours are applied by means of an aerograph with a pressure in the main air supply line of 0.9-1.1 atm. The parts of the coating are dried at room temperature for not less than two hours. After the application of the last colour of the coating, final drying of the obtained coating is performed at a temperature of 120-150°C for not less than two hours. A stencil is made from a material, resistant to a short-term exposure to organic solvents, which is fixed above the background layer by means of an adhesive layer and is removed after the application of the next colour of the coating.

EFFECT: providing the possibility of obtaining the coloured decorative coating on a technical fabric, obtaining a distinct contour of images in accordance with a specified pattern, resistance to an impact of the outer space factors in the process of the object exploitation on condition of the temperature difference.
