Preparation and Properties of Hydrophobic and Oleophobic Coating for Inkjet Printing

As a functional decorative material on the surface of printing and packaging, coating plays role increasing gloss, wear resistance, antifouling. It has broad application prospects in high-end printed materials such as posters, art reproductions, maps. In this paper, dodecafluoroheptyl methacrylate was used fluorine-containing monomer, which to modify epoxy resin introduce fluoride first. Under action polymerization inhibitor catalyst, further modified by ring opening, esterification, neutralization with acrylic acid, maleic anhydride, organic base raw materials. Additionally, hydrophobic oleophobic properties obtained finally. The effects fluorine modification synthetic polymer were characterized infrared spectrometer photoelectron spectroscopy. results showed that monomer could be successfully grafted molecular body resin, had been introduced into film. Using contact angle tester, combined performance parameters grafting rate, thermal stability, adhesion, amount discussed. copolymer film closely related monomer. When molar ratio group 26:1, mass fraction 18.09%, angles water ethylene glycol 121.8° 78.2° respectively. At same time, printability self-made tested paper. liquid repellency inkjet before after glazing influence optical images discussed studied too. synthesized experiment suitable for printing. improved quality printings, repellency, color reproduction.
