Four needle-like zinc oxide whiskers ( T -ZnOw ) as antistatic fillers , to improve the antistatic properties and mechanical properties of the composite material , use of the unique three-dimensional four needle-like structure and the higher strength and modulus to overcome the traditional anti static composite mechanical properties shortcomings . This article right T-ZnOw , surface modification , as well as T-ZnOw doped aluminum Experimental PVC / T-ZnOw antistatic composite material were prepared , and studied using a capillary rheometer , SEM, etc. , the flow of the composite material of PVC / T-ZnOw change behavior , mechanical and electrical properties . The research results show that the mechanical properties and electrical properties : the coupling agent handling the the T-ZnOw particles is more conducive to improve the mechanical properties of the composite material , but has little effect on the electrical properties of the composite . With the increase in T-ZnOw content , the mechanical properties of the composites showed a trend first and then decreased . The tensile strength of the composite material , room temperature impact strength , low temperature impact strength , flexural strength , respectively, in 15 parts , 8 parts , 5 parts and 10 parts of the maximum increased by 15% than that of pure PVC , respectively , 300 %, 30 %, 19 %. The surface resistivity of the composite material in the the T-ZnOw content of 8 parts reduced to 1 × 10 12 Ω, the volume resistivity the T-ZnOw content is reduced to 5 parts of 1 × 10 12 Ω, while the T-ZnOw doped with aluminum , the surface resistivity is reduced two orders of magnitude . The the rheological behavior research results show that : PVC and its composites are pseudoplastic fluid and non-Newtonian index of the composite as a whole is higher than PVC , the sensitivity of the shear rate is lower than PVC ; same shear rate , PVC / T-ZnOw the apparent viscosity of the composite material is higher than that of pure PVC ; activation energy of viscous flow of the composite material is higher than PVC , high sensitivity to temperature than PVC . For further improving the electrical properties of the antistatic composite material , the subject using a carbon black as filler is added to the PVC / T-ZnOw composite system , thus greatly improving the electrical properties of the composite material , the composite material surface resistivity in the carbon black is added in an amount is reduced to 6 parts by 10 4 Ω. With the addition of increasing the content of carbon black , a tensile strength of the composite material is gradually increased, the impact strength and elongation at break rendering decreased . Join ACR of PVC / ZnOw / carbon black composites toughened, to a large extent to improve the impact strength of antistatic composites .
