The invention discloses a multifunctional low carbon health-preserving paint, which comprises the following components in percentage by weight: 10 to 35% of pure water, 5.0 to 25% of vegetal negative ion liquid, 0.1 to 0.2% of pH adjuster, 0.2 to 2.0% of refreshing aid, 0.2 to 0.7% of antifoaming agent, 5.0 to 15% of nano level tourmalinite, 1.0 to 3.0% of nano far infrared aid, 0.5 to 2.0% of light free catalyst, 8.0 to 25% of heavy calcium carbonate powder, 8 to 20% of 828 titanium dioxide, 5.0 to 8% of calcined kaolin, 8.0 to 20% of diatomite, 0.5 to 3% of antistatic dustproof agent, 0.5 to 2% of purifying antibacterial agent, 15 to 35% of emulsion or resin with a formaldehyde adsorption function, 0.1 to 0.2% of bactericide, 1.0 to 2% of silver ion antibacterial agent, and 0.5 to 2% of film forming aid. The vegetal negative ion liquid, mineral negative ion powder, nano level tourmalinite, fare infrared material, plant phytoncide, light free catalyst, and the like, are merged together, the paint has the functions of common environmentally friendly paints such as self-cleaning, mildew resistance, dampness resistance, decorative effect, and the like; and moreover, the provided paint barely contains VOC and has a function of releasing far infrared rays and negative oxygen ions.
