Abstract

PURPOSE:To apply lining to give perfect anticorrosion in such a way that shape memorizing plastic is bound at the intermediate part of a stern tube by rubber binder. CONSTITUTION:RC lining 2 is applied to the bearing part (A) and the seal part C of a stern tube 1. Besides, polyethlene film 3 reinforced by crosslinking which is shape memorizing plastic to show strong resistance characteristic to sea water intrusion as its outer laminate plastic, is applied anticorrosion lining by thermal contractive action accompanied by interposition and heating of rubber binder 4 that is excellent in adhesive property with metal and polyethylene to be inner laminate binder, and has water-proofing property, in the intermediate part B between the bearing part (A) and the seal part C of said stern tube 1.
