Preparation and Properties of Siloxane Modified Epoxy-styrene-acrylic Aqueous Dispersion
Abstract:
Stable epoxy-styrene-acrylic aqueous dispersion modified with siloxane was prepared with a two-step synthetic method.FTIR,SEM and TGA were used to characterize the structure and property of the product.The results show that the epoxy was chemically modified by styrene-acyrlic and γ-aminopropyl methyl diethoxysilone (A-2100).Its microphase structure was formed before curing.The membrane has a fine microphase structure,and the size of the microphase region was 0.2~0.5 μm.At the same time it had similar thermal stability as the epoxy-styrene-acrylic copolymer,and the mass loss was 5% at 181.The membrane exhibited good chemical resistance.The viscosity of the dispersion did not change greatly after 180 d.
