S2. Put the pulverized mixed material prepared in step S1 into a banbury mixer for banburying. The temperature of the banbury mixer is set to 140-160°C, the speed is set to 800-900r/min, and the banbury mixer time is 20- 30min, made banburying material;

S3, adding the banburying material prepared in step S2, zinc oxide powder, epoxy resin powder, anti-aging agent, accelerator, softener, tricresyl phosphate to the reactor for stirring and mixing, the temperature of the reactor Set it to 200-220°C, set the speed to 900-1000r/min, and set the time to 20-25min to prepare the glued material;

S4. Put the glued material prepared in step S3 into an ultrasonic disperser for dispersion. The power of the ultrasonic disperser is set to 200-240W, the temperature is set to 130-150°C, and the dispersion time is set to 16-20min to obtain dispersed materials;

S5, adding the dispersed material prepared in the step S4 into a platen pressing machine for pressing and forming, so as to obtain a non-slip cushion blank;

S6. Trimming and cutting the blank of the anti-slip buffer pad prepared in step S5 to obtain an anti-slip buffer pad.

8 . The method for preparing a non-slip buffer pad according to claim 7 , wherein the particle diameter of the pulverized mixed material in the step S1 is 5-8 mm.

9. the preparation method of a kind of anti-slip buffer pad according to claim 7, is characterized in that: described anti-aging agent is p-phenylenediamine, and described accelerator is diethylthiourea, and described softening agent is paraffin oil .
