METHOD OF MANUFACTURE OF THE MULTILAYER PRODUCT CONTAINING THE LAYER OF FLUOROPLASTIC AND THE LAYER OF ELASTOMER Russian patent published in 2006 - IPC B29C47/06 B32B37/14 B32B1/08 

FIELD: chemical industry; methods of manufacture of the multilayer products containing the layer of fluoroplastic and the layer of elastomer.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the method of manufacture of the multilayer product containing the layer of fluoroplastic and the layer of elastomer. The method provides for preparation of the product containing the layer of the solidified elastomer. At that the product has the outer surface ready for the fluoroplastic layer application on it. The method provides for the thermal insulation of the solidified elastomer before application of the fluoroplastic layer on it. Then apply the fluoroplastic composition containing the regularly alternating links being formed at polymerization of vinyliden fluoride on the outer surface of the product with the purpose of production of the fluoroplastic layer. Then they heat the fluoroplastic layer and solidify the layer of the solidified elastomer. The invention presents the descriptions of the versions of the method realization and the produced product. The invention allows to increase the strength of binding between the fluotoplastic vinyliden fluoride layer and the layer of the elastomer in the multilayer product.

EFFECT: the invention allows to increase the strength of binding between the fluotoplastic vinyliden fluoride layer and the layer of the elastomer in the multilayer product.
