A method for preparing an acrylic emulsion for flooring

Abstract

This invention discloses a method for preparing an acrylic emulsion for flooring, belonging to the field of acrylic emulsion technology, comprising the following steps: S1, preparing a first emulsifying component and a second emulsifying component, mixing the first emulsifying component and the second emulsifying component and emulsifying them into a pre-emulsion; S2, preparing a bottom liquid and an initiator solution, taking a portion of the initiator solution and a portion of the pre-emulsion and reacting them in the bottom liquid to obtain a seed emulsion; S3, reacting the remaining initiator solution and the remaining pre-emulsion in the seed emulsion to obtain a base emulsion; S4, preparing an oil phase component and an aqueous phase component, mixing and emulsifying the oil phase component and the aqueous phase component, cooling and precipitating to obtain cross-linked microcapsules; S5, mixing and stirring the cross-linked microcapsules with the base emulsion to obtain an acrylic emulsion; After the acrylic emulsion of this invention is coated on the surface of the flooring and laid and fixed, the glass transition temperature of the emulsion coating is significantly increased.
