Ink and preparation method thereof

The invention relates to the technical field of ink, and especially relates to an ink and a preparation method thereof. Adopted stirring equipment comprises a stirring tank, a feeding port communicated with the inner cavity of the stirring tank is formed in one side of the upper end of the stirring tank, a motor is fixedly arranged in the middle of the upper end of the stirring tank, the output end of the motor is connected with a rotating shaft, and the rotating shaft penetrates through the upper end of the stirring tank and extends downwards to the inner cavity of the stirring tank. A plurality of groups of stirring rods are arranged on the rotating shaft at the lower part in the stirring tank at intervals. Through the arrangement of a grinding block and a grinding disc, particles of rawmaterials can be smaller, dispersion of the raw materials during subsequent stirring and emulsifying is facilitated, the uniformity of substances in the ink is improved, the overall viscosity is better, then the adhesive for
