Embodiment 1
[0025] A preparation method of modified resin ink coating, comprising the following steps:
[0026] 1) Take an appropriate amount of polyester-modified methylphenyl silicone resin, titanium dioxide and barium sulfate and add it to a fine grinder, grind and disperse at a speed of 2000~2500r / min for 30 minutes to obtain primary products and set aside;
[0027] 2) Add appropriate amount of dispersant, silane coupling agent, octylphenol polyoxyethylene ether, modified chlorinated polypropylene, polytetrafluoroethylene wax and aminotrimethylphosphoric acid to the primary product obtained in step 1). Grind and disperse for 60 minutes at a speed of 2000~2500r / min to obtain a secondary product for later use;
[0028] 3) Add an appropriate amount of hexamethoxymethylmelamine resin to the secondary product obtained in step 2), grind and disperse for 15 minutes at a speed of 800~1000r / min, filter the material through a 200-mesh filter, and obtain the ink main agent for future use ;
