▎ 摘　　要

NOVELTY - Color paste compatible inorganic building coating composition comprises a component A and a component B. The component B is general color paste. The component A comprises 25-30 wt.% siloxane oligomer, 1-5 wt.% water-based acrylic resin, 0.05-2 wt.% graphene oxide, 0.2-0.5 wt.% dispersing agent, 0.2-0.5 wt.% defoaming agent, 25-30 wt.% inorganic filler, 1-2 wt.% thickening agent, and balance is deionized water. USE - Color paste compatible inorganic building coating composition. ADVANTAGE - The water-based building coating is a weak acid system, which does not influence the stability of color paste, adopt common general organic color paste on the market for color mixing without flocculation, that has good stability, cost-effective and wide color selection range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing mill base compatible inorganic architectural coating composition, which involves: (1) mixing graphene oxide with deionized water, and performing ultrasonic dispersion to obtain a graphene oxide dispersion liquid; (2) uniformly mixing siloxane oligomer, a dispersing agent, inorganic filler, deionized water, 50-70 wt.% defoaming agent and graphene oxide dispersion liquid, grinding and filtering to obtain filler slurry; (3) preparing a thickener into 5-10 wt.% transparent solution, and uniformly mixing with the filler slurry, the water-based acrylic resin and the balance of the defoaming agent; (4) adding the universal color paste into the paint, and uniformly mixing.
