METHOD OF PRODUCING LAMINATE AND LAMINATE Russian patent published in 2022 - IPC C08J5/18 B32B1/08 B32B25/04 B32B25/14 B32B27/26 B32B37/14 

FIELD: production of laminates.

SUBSTANCE: invention relates to production of laminates suitable for use in highly alkaline environment, for example, as fuel rubber hose for cars. Disclosed is a laminate and a method of producing the laminate. Method of producing a laminate, comprising producing a non-crosslinked laminate having a layer of a first composition comprising a copolymer having fluorine atoms, as well as a layer of a second composition comprising a non-fluorinated elastic polymer, and a cross-linking of the first composition and the second composition for producing a laminate having a first layer, formed from a cross-linked product of a first composition, and a second layer formed from a cross-linked product of a second composition, in which, when the first composition and the second composition contain a common cross-linking additive, the absolute value of the cross-linking rate difference between the first composition and the second composition is at most 0.30.

EFFECT: invention enables to obtain a laminate having excellent alkali resistance and peel strength at high temperature.
