▎ 摘  要

NOVELTY - Graphene waterproof paint comprises 8-22 pts. wt. polyisocyanate, 1-10 pts. wt. organosilicone waterproofing agent, 2-10 pts. wt. graphene slurry, 0.2-0.8 pts. wt. antifoaming agent, 0.1-0.6 pts. wt. wetting dispersant, 0.1-0.6 pts. wt. carboxymethyl cellulose, 2 pts. wt. calcined diatomite, 3 pts. wt. expanded perlite, 3 pts. wt. tourmaline powder, 1-2 pts. wt. bamboo fibers and 10-30 pts. wt. deionized water. USE - Used as graphene waterproof paint. ADVANTAGE - The paint: has excellent permeability, film-forming property, water resistance and elasticity, excellent adhesion, toughness and high- and low-temperature resistance; can be suitable for construction operations on dry or wet base layers without clear water; and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene waterproof paint, comprising (i) adding tourmaline powder, calcined diatomite, expanded perlite and bamboo fibers, grinding for 5 minutes and mixing uniformly, (ii) mixing polyisocyanate, organosilicone waterproofing agent, wetting dispersant, carboxymethyl cellulose and deionized water, mixing clock wise for 5 minutes, and (iii) adding graphene slurry and antifoaming agent, stirring clock wise and anticlockwise alternately for 10 minutes, adding mixture obtained in steo (i) into the two mixtures obtained in steps (ii) and (iii), continuously stirring for 20 minutes, and discharging.
