摘 要:使用木质素磺酸钠作为抗静电剂,己内酯为分散剂,与聚氯乙烯(PVC)共混制备了抗静电PVC复合材料。当己内酯添加量为4份,木质素磺酸钠添加量为5份时,PVC复合材料表面电阻为7.2×107 Ω,达到了抗静电制品的表面电阻要求。抗静电材料PVC复合材料弯曲模量为1 114 MPa,与未添加抗静电剂的聚氯乙烯材料相比提升3.1%;拉伸强度为42.63 MPa,降低7.8%。 |

Abstract:Antistatic PVC composite was prepared using sodium lignosulfonate (SLS) as antistatic agent by melting blending while caprolactone (CL) was used as a dispersant. When the amount of CL was 4 parts and the amount of SLS was 5 parts, the surface resistance of PVC composite material was 7.2×107 Ω, which met the surface resistance requirements of antistatic products. The bending modulus of this antistatic material was 1 114 MPa, which was 3.1% higher than that of PVC material without antistatic agent. Tensile strength was 42.63 MPa, a reduction of 7.8%. |
Key words:sodium lignosulfonate; antistatic agent; caprolactone |
