▎ 摘  要

NOVELTY - A water and gas barrier coating comprises polymer having a solid content of 20-35% and amine, hydroxyl, and carboxylic groups and graphene having solid content of 0.5-1%, sheet diameter of 3-10 microm, and number of layers is 1-10 layers. USE - Water and gas barrier coating. ADVANTAGE - The coating solves the problem of lacking of good water blocking and/or gas blocking effect to a certain extent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for water and gas barrier structure comprising water and gas barrier layer formed by coating and drying the water and gas barrier paint.
