Abstract
A method for preparing a styrene-acrylate siloxane interpenetrating polymer network (IPN) composite emulsion is provided. The styrene-acrylate siloxane IPN composite emulsion prepared by the method can effectively improve the compatibility of the styrene-acrylate component and the siloxane component, and realize the gradient orientation distribution and ordered microphase separation of various styrene-acrylate molecules and siloxane molecules, thereby improving the synergistic working performance of a styrene-acrylate coating and a siloxane coating, and endowing the composite protective emulsion with excellent rheological properties, waterproof properties, anti-ion penetration properties, anti-carbonization properties, acid and alkali corrosion resistance, and anti-aging properties.
