Polyethylene resin foam particles having antistatic performance, and polyethylene resin in-mold foaming molded product and method for manufacturing same

A method for producing expanded polyethylene resin particles, the method comprising:

• forming a mixture by dispersing polyethylene resin particles and a foaming agent in an aqueous dispersion medium;
• heating the mixture to a temperature equal to or higher than a softening temperature of the polyethylene resin particles;
• applying a pressure to the mixture in a sealed container;
• and
• releasing the mixture into a zone having a pressure lower than an internal pressure of the sealed container, producing the expanded polyethylene resin,
• wherein the polyethylene resin particles comprise an antistatic agent and a base resin, the polyethylene resin particles having a storage modulus of elasticity of 900 to 5000 Pa at an angular frequency of 1 rad/sec in dynamic viscoelastic behavior measurement at 190° C. and a storage modulus of elasticity of 100000 Pa or less at an angular frequency of 100 rad/sec in dynamic viscoelastic behavior measurement at 190° C., and
• wherein the expanded polyethylene resin particles have a low temperature side melting peak and a high temperature side melting peak on a differential scanning calorimetry (DSC) curve obtained when a temperature of the expanded polyethylene resin particles is increased from 20° C. to 220° C. at a heating rate of 10° C./min.
