▎ 摘  要

NOVELTY - A graphene self-crystalline waterproof active masterbatch comprises 3-15 wt.% graphene oxide, 55-75 wt.% calcium compensating agent, 5-30 wt.% permeated crystalline agent, and 2-10 wt.% chelating agent. USE - A graphene self-crystalline waterproof active masterbatch used for building inner and outer walls, basement, tunnel, moisture-proof porous masonry structure, decorative layers (claimed). ADVANTAGE - The masterbatch is compact, and has improved waterproof effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the graphene self-crystalline waterproof active masterbatch, comprising adding graphene oxide in water, and ultrasonic and mechanical stirring for 1-6 hours; orderly adding calcium compensating agent, permeated crystalline agent, and chelating agent, and mixing for 1 hour to obtain a slurry; and spray-drying to obtain particles having particle size of 100-500 mu m.
