MULTILAYER POLYMER-TEXTILE MATERIAL AND PRODUCTION METHOD THEREOF Russian patent published in 2012 - IPC B32B27/40 

FIELD: chemistry.

SUBSTANCE: invention relates to production of plastic and can be used to produce air-tight inflatable articles. The material contains polyester fabric as a textile base, on whose surface an alloy containing the following is deposited through vacuum coating, wt %: 68.2 Fe, 2.0 Mn, 11.6 Ni, 17.5 Cr, 0.7 Ti in amount of 1.0-2.0 g/m², an adhesive layer based on a polyester urethane composition and a front coating based on polyester urethane composition in form of 2-4 layers, deposited on the front or front and back sides, with the following weight ratio of the layers of the ready material: textile base: adhesive layer: front coating equal to 1.0:0.25-0.57:0.60-0.86, for one-side coating or 1.0:0.40-0.86:0.75-1.28 for double-sided coating using a direct method and 1.0:0.20-0.43:0.35-0.71 or 1.0:0.35-0.57:0.50-1.0 using a reverse method.

EFFECT: material obtained using direct and reverse methods has high bonding strength between the polymer coating and the fabric and weld strength, which ensures long life of different air-tight inflatable articles made from said material.
