The invention relates to elastic latex paint provided with the functions of dewfall prevention and 
mildew-proof. The elastic latex paint comprises a pulping component and a paint mixing component, wherein the pulping component and the weight ratio thereof adopt that water occupies 8 percent to 10 percent, 
propanediol occupies 2 percent to 5 percent, dispersant occupies 0.4 percent to 0.8 percent, 
wetting agent occupies 0.2 percent, antifoaming agent occupies 0.2 percent, 
antiseptic occupies 0.15 percent, dry film anti-
mildew agent occupies 0.6 percent, 
anatase titanium dioxide occupies 4 percent to 7 percent, expanded 
perlite occupies 20 percent, calcined kaolin occupies 7 percent, diatomite occupies 10 percent, and heavy 
calcium 800 head occupies 8 percent; the paint mixing component and the weight ratio thereof adopt that elastic 
emulsion occupies 30 percent to 40 percent; film forming additive occupies 0.5 percent, antifoaming agent occupies 0.2 percent; pH conditioning agent occupies 0.15 percent to 0.2 percent, 20 percent of 
aqueous solution of thickener occupies 4 percent to 5 percent, leveling agent occupies 1 percent to 1.5 percent, and the residual is water. The elastic latex paint is used for preventing the breeding of the 
mildew and the dewing on the inner wall of the cigarette factory, and the elastic latex paint has the advantages of economy and practicality, obvious 
efficacy, and is simple and convenient for manufacturing, storage and transportation.
