Modified polyethylene resin powder composition for inner surface coating of steel pipe for water

摘要

The present invention relates to a modified polyethylene powder resin composition for coating the inner surface of a steel pipe for water service, and more particularly, to a water service that does not reduce the adhesion and mechanical properties of the coating layer when the end of the modified polyethylene powder coated on the inner surface of the water service pipe is expanded at room temperature. It relates to an improved modified polyethylene powder resin composition for inner coating of steel pipes. According to the present invention, by using a low-density thermoplastic elastomer excellent in ductility at room temperature and metal oxide in an efficient mixing ratio, even when the end of a steel pipe for water supply is expanded, physical properties such as adhesion of the inner coating layer are reduced. can
