                      Abstract:This  paper  studied  the  influence  of  different  kinds  of  functional  fillers  on
                 solvent-free epoxy coating performance. Micaceous iron oxide and calcium exchange SiO  were

                 selected  as  the  antirust  fillers  to  enhance  the  corrosion  resistance  of  the  coatings. Barium
                 sulphate  precipitated  with  ceramic  powder  were  used  to  improve  the  wear  resistance  of  the
                 coatings,and  solvent-free  epoxy  coatings  with  different  filler  compounds  were  prepared  by
                 orthogonal test method at the appropriate pigment/binder ratio. The effects of the mass ratio of
                 the fillers on the coating properties were analyzed and studied by basic physical property tests,
