EXTRUSION OF ADHESIVE FOR LAMINATES FROM DYNAMICALLY CURED THERMOPLASTIC ELASTOMER Russian patent published in 2015 - IPC B29C47/06 

FIELD: process engineering.

SUBSTANCE: invention relates to extrusion of sandwiched extruded article, laminate and pneumatic tire. Barrier layer comprises dynamically cured thermosetting elastomer composition existing in one or more seams of barrier layer. Underlying layer comprises first seam of adhesive composition to connect barrier layer and second seam. Adhesive layer comprises second seam to be cured with diene-based rubber. Underlying adhesive layer can be laid in contact with relatively hot thermosetting elastomer to reduce the adhesive outer layer temperature. Adhesive outer layer is protected against overheating and can be cured with rubber in tire production.

EFFECT: higher physical-mechanical properties.
