Embodiment 1
[0023] a. Synthesis of active solvation segments:
[0024] 80% of butyl acrylate, 10% of styrene, and 10% of cyclohexane; add the corresponding regulator, initiator and reaction medium, the regulator is 0.3% of dodecanethiol, and the initiator of azobisisobutyronitrile is 1%. Reaction medium liquid paraffin 150%. Put each material into the reactor according to the above proportions, control the reaction temperature to be 70 degrees, the stirring speed is 400 revolutions per minute, and the reaction time is 4 hours; when the measured conversion rate reaches 95%, the material is discharged; it is prepared into an active solvation segment.
[0025] b. Graft polymerization of anchoring groups:
[0026] In the reactor, pour 90% of the active solvated segment prepared in the previous stage, 10% of γ-(methacryloyloxy)propyltrimethoxysilane, 0.5% of initiator azobisisobutyronitrile, regulator Dodecanethiol 0.2% mixture is gradually added dropwise to the reactor, the temperature is c...
