s4: after hot melting is finished, the raw materials can be put into an extruder, then the fatty alcohol ether sodium sulfate and the sodium benzoate are sequentially added, so that the hardness and the corrosion resistance of the electrostatic film can be respectively improved, and the raw materials are extruded into a strip-shaped blank by the extruder;
s5: putting the embryo body into a rolling machine, and rolling the embryo body into a basement membrane in batches;
s6: and (3) combining the three base films into a group, sequentially passing through a rolling machine, and adding an adhesive between two adjacent base films to obtain the electrostatic film.
7. The antistatic film for electronic components as claimed in claim 6, wherein in S1, a hot air system is disposed in the electric heating box, and the base material, polypropylene and polyvinyl chloride are uniformly dried in the form of wind power, so as to effectively avoid overheating of the base material, polypropylene and polyvinyl chloride.
8. The antistatic film for electronic components as claimed in claim 6, wherein in S5, the thickness of the base film is 0.1-0.15 MM.
