NOVELTY - A waterproof and mildew-proof composite paint comprises 16.60-18.20 wt.% acrylate emulsion, 0.68-0.84 wt.% film-forming aid, 0.28-0.36 wt.% defoamer, 45.40-46.20 wt.% Portland cement, 17.10-17.70 wt.% quartz sand, and remaining composite filler. USE - Waterproof and mildew-proof composite paint. ADVANTAGE - The waterproof and mildew-proof composite paint avoids the breeding of a large number of bacteria and mold on the surface of the paint after long-term use, ensures the cleanliness and comfort of the environment, reduces the damage of bacteria and mold simultaneously, and adopts nano-silver particles and nano-zinc oxide to effectively enhance antibacterial of composite paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the waterproof and mildew-proof composite paint, which involves (1) weighing waterproof and mildew-proof composite paint, (2) adding composite filler to a counter-jet jet mill for processing to obtain a mixture (A), (3) adding the mixture (A) to deionized water, and ultrasonically treating for 30-40 minutes to obtain a mixture (B), (4) electrospinning the mixture (B) to obtain composite fiber, (5) adding Portland cement and quartz sand to the counter-jet jet mill for processing to obtain a mixture (C), and (6) uniformly mixing acrylate emulsion, film-forming aid, defoamer, composite fiber, and the mixture (C).
