METHOD OF PRODUCTION OF THE LAMINATED MATERIAL WITH THE POLYVINYLCHLORIDE COATING Russian patent published in 2007 - IPC B32B27/00 C08L27/06 D06N3/06 

FIELD: chemical industry; other industries; methods of production of the of the laminated material with the polyvinylchloride coating.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to production of plastics, namely - to the development of the method of production of the laminated material with the polyvinylchloride coating. The method is realized by deposition at heating up to temperature of 150-190°С on the textile base of the coating consisting of the polyvinylchloride composition including the film forming agent - polyvinylchloride suspension, the plasticizers - di-(2-ethylhexyl)- phthalate, chlorinated paraffin wax and the mixture of dioxane alcohols and their high-boiling ethers with the number of the hydroxyl groups of 23-36 %, the filler - the chalk and the crystalline calcium carbonate, the stabilizing agent - the stearic acid and calcium - the zinc complex stabilizing agent , the surface active agent - the flotation reactant - oxalic agent, the pigment - titanium dioxide, as the textile basis they use the cloth thermo bound by the surface density of 46-54 g/m² made out of the polyester filaments with the density of 0.12-0.33 tack and the cutting length of 38-66 mm. The laminated material with the polyvinylchloride coating has the bonding strength of the film coating with the base of 2.0-2.3 kN/m, the rigidity of 0.4-0.9 cN and variation of the linear dimensions lengthways of 0.4-0.7 % and transversely - 0.1-0.3 %.

EFFECT: the invention ensures, that the laminated material with the polyvinylchloride coating has the bonding strength of the film coating with the base of 2.0-2.3 kN/m, the rigidity of 0.4-0.9 cN and variation of the linear dimensions lengthwise and transversely are less than unity.
