Research On Preparation Of Hydrophilic Faced Coating And Antiseptic Bottom Coating And Cooperation Effect

Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer(AA,HEA)as aided surfactant were used to prepare grafted amphiphilic polymer by soap-free microemulsion copolymerization. This amphiphilic polymer was neutralized in some degree, then amidocyanogen resin(717) was put into this system. The hydrophilic face coating was prepared. AA,HEA,MMA,BA,St,epoxy resin were used to prepare antiseptic bottom coating, before the resin was dispersed, it must be neutralized organic amine, 717 must be added into, too.Particle's morophology was observed by TEM. The conditions of amphiphilic polymer's micro-phase separation was characterized by DSC. When the amphiphilic polymer was set, its surface tension could be known by measured water in its surface spread-diameter. NaOH(20wt%) and salt-fog experiment were used to measure bottom coating's corrupt resistance.Results showed that macromolecular monomer could be grafted into main chain, it also could be micro-phase separated. Good and long time hydrophilic amphiphilic polymer could be obtained. The particle diameter was less and its distribution was uniform. Acrylate resin rectified by epoxy resin was better in anti-erode than only acrylate resin used. Face coating and bottom coating matched well, the tropism of face coating on bottom coating could be carried out easily, the adhesion force was big enough to anti- rubbing and anti- washing.
