High-efficiency formaldehyde-removing anti-doodling acrylic emulsion as well as preparation method and application thereof

The invention discloses an acrylic emulsion for efficiently removing formaldehyde and resisting graffiti of an artistic coating finishing surface as well as a preparation method and application of the acrylic emulsion. The emulsion is prepared from the following monomer components in percentage by weight through an emulsion polymerization method and then steam stripping: a) 15-70%, preferably 44-53%, of ester monomers; b) 14-25%, preferably 10-15%, of an aldehyde removal monomer; the invention relates to a water-based formaldehyde-removing emulsion, which is prepared from the following components in percentage by weight: 1-5% of an aldehyde-removing monomer containing triazole amido, 0.5-5% of an unsaturated hydrophilic monomer preferably 1-5%, 0.2-5% of a reactive silane coupling agent preferably 0.5-2%, and 10-50% of styrene preferably 10-30%. The formaldehyde-removing monomer containing triazole amido is added into the emulsion, and a conjugated structure on triazole powerfully improves the reaction capaci
