NOVELTY - Coating comprises 20-28 pts. wt. alkyd resin, 14-22 pts. wt. styrene-acrylic emulsion, 12-18 pts. wt. water, 12-16 pts. wt. talcum powder, 12-18 pts. wt. temperature control filler, 4-6 pts. wt. film-forming aid, 1.8-2.4 pts. wt. thickener, 0.1-0.3 pts. wt. wetting agent, 0.4-0.6 pts. wt. dispersant, 3-5 pts. wt. anti-mildew and fungicide, and 0.1-0.2 pts. wt. defoamer. USE - Coating used for building exterior wall. ADVANTAGE - The coating has good heat preservation and insulation performance, waterproof performance, mildew-proof and corrosion-proof performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for preparing coating, which involves: (a) adding water, styrene-acrylic emulsion, talcum powder, wetting agent, dispersant, anti-mold and fungicide into the container for ultrasonic dispersion with specific portion by weight to obtain a homogeneous mixture, setting to aside; (b) adding continuously alkyd resin, temperature control filler, and film-forming aid to the obtained homogeneous mixture, heating up; (c) stirring, mixing to obtain the primary mixed coating, setting to aside; (d) adding a thickener and a defoamer to the obtained primary mixed coating, stirring, and mixing to obtain the coating for building exterior walls; and 2. a hydrophobic temperature-controlling microsphere is prepared by preparation method.
