Abstract: The polysiloxane- polyacrylate emulsion coatings is prepared by the process of seed emulsion polymerization. It can be used as an efflo rescenceproof material to protect the stone sculpture a long hills.The influences of monomerratios, in itiator content and emulsifier content on the properties of emulsion coa-tings are discussed by orthogona l experimental design. The optimum experimenta lconditions are given. The stucture of emulsion coatings is characterized by use of FT- IR, TEM and DSC.
