The utility model relates to a base material mixing device for preparing
bisphenol A
cyanate ester, which comprises a mixing reaction tank, a stirring shaft, a stirrer, a discharging
pipe, a driving motor, a spiral conveyor, a
powder bin, a dispersing box, a dispersing coil
pipe and a blanking
pipe, a
solvent inlet pipe is arranged on the left side of the mixing reaction tank, and a
solvent conveying pump is arranged on the
solvent inlet pipe; the solvent inlet pipe is connected with an upper conveying pipe and a lower conveying pipe, the upper conveying pipe is connected with the dispersing coil pipe, a pipeline mixer is arranged on the lower conveying pipe, the lower conveying pipe extends into the lower part of the mixing reaction tank, the lower conveying pipe is connected with a liquid base material inlet pipe, and a liquid material conveying pump is arranged on the liquid base material inlet pipe. By arranging the pipeline mixer, the dispersing box and the dispersing coil pipe,
bisphenol A and
cyanate ester can be separately mixed with an
organic solvent in a flowable manner, and then enter the mixing reaction tank for mixing reaction, so that the
mixing effect is better, the mixing speed is higher, the
bisphenol A cannot be caked, and the reaction is more facilitated.
