The invention belongs to the field of water-based polymer materials, in particular 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. Modified potassium silicate styrene-acrylic emulsion includes methyl methacrylate, butyl acrylate, styrene, sodium bicarbonate, potassium persulfate, emulsifier, silane coupling agent, quaternary ammonium salt containing unsaturated double bonds, silicone Modified potassium silicate, protective glue, water. The preservative-free solvent-free water-based polymer material provided by the present invention does not add preservatives and organic solvents, has extremely low VOC, SVOC, TVOC, free formaldehyde is not detected, and has excellent resistance to efflorescence and salinity. , storage stability and other characteristics. |
