| Abstract: | In this article,epoxy resin is modified with p-Aminobenzoic acid,which confer water dispersibility to the otherwise water-insoluble resin.The DSC thermograms indicate that the modified resins have good compatibility with unmodified resin.The modified resins are mixed with unmodified resin in different ratio to prepare waterborne coating.The films of the modified resin and the mixture show good properties in luster,impact strength,hardness,adhesion and flexibility.While keeping the advantages of the solvent-based epoxy resin such as high hardness, the films show a great improvement on flexibility.And this waterborne system also has excellent performance on water-resistance and chemical agent resistance. |
