Reparation and Performance Representation of Long-acting Antistatic Polyethylene Film
Polyethylene wax (PEW) compatible with polyethylene (PE), and sodium acrylate (AAS) with antistatic ability were used to prepare an antistatic agent (PEW-g-AAS) with significant antistatic effect and long-lasting effect by solution grafting method. Antistatic polyethylene films were prepared by casting by blending antistatic agents with linear low-density polyethylene/low-density polyethylene (LLDPE/LDPE), and the effects of PEW-g-AAS on the properties of PE films were studied. The results show that with the increase of PEW-g-AAS mass fraction, the water contact angle of the PE film decreases, the surface energy increases, and the mechanical properties decrease slightly. When the PEW-g-AAS mass fraction is 20%, the surface resistance of the PE film decreases to 5.20×109 Ω, and the surface resistance of the PE film is stable within 1~30 days.
