Modified potassium silicate styrene-acrylic emulsion and preparation method thereof as well as preservative-free and solvent-free water-based polymer material and preparation method thereof

The invention belongs to the field of water-based polymer materials, and particularly relates to a modified potassium silicate styrene-acrylic emulsion and a preparation method thereof as well as a preservative-free and solvent-free water-based polymer material and a preparation method thereof. The modified potassium silicate styrene-acrylic emulsion comprises methyl methacrylate, butyl acrylate, styrene, sodium bicarbonate, potassium persulfate, an emulsifier, a silane coupling agent, quaternary ammonium salt containing unsaturated double bonds, organic silicon modified potassium silicate, protective glue and water. The preservative-free solvent-free water-based polymer material provided by the invention is not added with preservatives and organic solvents, has extremely low VOC (Volatile Organic Compounds), SVOC (Soluble Volatile Organic Compounds) and TVOC (Total Volatile Organic Compounds), does not detect free formaldehyde, and has the characteristics of excellent alkali burnout resistance, alkali burnou
