▎ 摘　　要

NOVELTY - A one-component coating composition contains 95-96 wt.% waterproof emulsion, 0.5-1.5 wt.% emulsifier, 0.1-0.3 wt.% defoamer, 1.5-2.5 wt.% rubber powder, 1.5-2.8 wt.% graphite powder and 0.1-0.5 wt.% graphene. USE - One-component coating composition (claimed). ADVANTAGE - The one-component coating composition is inexpensive and convenient to use, and has excellent alkali resistance and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of one-component coating composition, which involves adding waterproof emulsion to reaction kettle, controlling the temperature at 35-50 degrees C for 8-10 minutes, evenly adding graphene for 8-10 minutes, then dripping emulsifier, then adding rubber powder and graphite powder for 5-10 minutes and finally adding defoamer for 5-10 minutes.
