Abstract
A kind of carbon black (CB), which was surface-treated by silane-coupling agent, was compounded with high-density polyethylene (HDPE) in a twin-screw extruder, and then the composites were molded into specimens with a plastic injection molding machine. The weight fractions (φf) of the CB were 0, 3, 5 and 8%. The effects of CB loading on the mechanical properties, such as tensile yield strength, tensile fracture strength, tensile fracture elongation, flexural strength, flexural modulus and impact strength of the HDPE/CB antistatic composites, were investigated. The results expressed that the tensile fracture strength, flexural strength and flexural modulus increased obviously with an addition of φf. When φf was less than 5%, the tensile fracture elongation of the composites raised, it exhibited a maximum value when φf was approximate to 5%, then it declined. The impact strength decreased evidently with increasing φ f when φf was less than 3%, while it decreased gently when φf was more than 3%.
