PREPARATION OF SILOXANE-MODIFIED EPOXY RESIN AQUEOUS DISPERSION AND ITS FILM PROPERTY
|
Abstract:
A stable epoxy aqueous dispersion was prepared by copolymerizing vinyl monomers onto epoxy resin,by neutralizing with triethanolamine and by grafting with siloxane.The modification condition and the siloxane content on the properties of the aqueous dispersion and its coating were studied.FTIR and TG were used to characterize the structure and analyze the thermal stability of the product,respectively.The results showed that when the weight fraction of siloxane was 2%~2.5%(based on epoxy resin weight),the rea...
