Provided is a method for producing nano silicon dioxide and nano calcium carbonate by using rice hull ash and flue gas of a biomass power plant. The method comprises: adding the rice hull ash into a sodium hydroxide solution, fully reacting at the temperature of 95-100 °C for 3-4 hours, and performing filtration; adding water into a filtrate to dilute the filtrate, controlling sodium silicate in a system to be 8-15 wt% in silicon dioxide, heating to 60-80 °C, adding a dispersing agent, continuously feeding the flue gas of the biomass power plant under a normal pressure condition, stirring to react for 2-4 hours to obtain the nano silicon dioxide; mixing the filtrate and a washing liquid, adding a calcium hydroxide solution at the temperature of 50-70 °C, and stirring to react for 0.5-2 hours to obtain the nano calcium carbonate. The particle sizes of the silicon dioxide product and the calcium carbonate product which are obtained by the method are extremely small and can both reach the nano level.

The present invention relates to a method for preparing a biomass-based polymer emulsion. The method comprises: dissolving cardanol in a solvent a , adding a sulfonating agent and strong alkali, reacting and cooling, adjusting the pH value and reacting again, cooling overnight, filtering, dissolving a solid washed by the solvent a in an anhydrous solvent b, adding a modifier and triethylamine., and carrying out the polymerization reaction to obtain a cardanol-based emulsifier; after modifying castor oil by using maleic anhydride, adding isocyanate, a catalyst and a chain extender for polymerizing to obtain a castor oil-based polyurethane prepolymer; and adding an acrylate monomer and water into the castor oil-based polyurethane prepolymer and the cardanol-based emulsifier, swelling, rising the temperature to 70-90°C for reaction, and adding an initiator to initiate the polymerization. By using the present invention, acrylate is copolymerized in a system with a cardanol-based polymerizable emulsifier as a medium and double bonds on a castor oil derivative are used for graft copolymerization, so that a prepared emulsion is high in compatibility, good in stability, good in water tolerance, good in chemical tolerance and good in weather tolerance, has the advantages of incombustibility, no toxicity, no environmental pollution and the like, and is wide in use.
