摘要：

The low melting point metals (SnCu alloy and Sn) and HDPE were mixed through the internal mixer. The effects of mixing time, rotary speed and Sn content on average diameter of Sn particles and volume resistivity were studied. It is found that low-melting-point metals assemble and separate out partly in the case of metal volume fraction above 0.65% or mixing time above 5 min. When metal volume fraction is 0.65% and mixing time is 5 min, the assembling becomes unobvious. The average diameter of Sn particles in composite decreases early and then increases with the increase of mixing time, decreases early and then becomes invariant with the rotary speed increasing, and increases early and then decreases with the Sn content increasing. These factors also affect the volume resistivity of Sn/HDPE composite, but the effects of mixing time and rotary speed on volume resistivity are attribute to the effect of Sn particles size in composites.
