新型软塑材料防静电复合技术研究

Research of New Anti-static Composite Technology of Soft Plastic Materials

通过对导电炭黑填充量对导电性能的探索,优选了集经济性、工艺适性于一体的油炉法炭黑。将油炉法炭黑和聚乙烯树脂混炼造粒,得半导电粒子,经三层(ABC)共挤吹膜工艺和电晕处理技术,制得高表面能防静电聚乙烯薄膜;该薄膜可与其他基材可靠复合成机械物理性能优异的防静电软塑包装复合材料。该产品广泛应用于对静电以及电磁辐射敏感的电子、化工及军工产品的包装,起到良好的静电、电磁和机械物理防护作用。

Through study the effect of carbon black filler content on conductivity, oil furnace carbon black with good economy and technology was selected. Carbon black and polyethylene resin were mixed and granulated to get the semi-conductive particles. Through three-tier （ABC） co-extrusion blown film process and eorona treatment technologies, the polyethylene fihn of high-antistatic surface were prepared. With other substrate film, excellent antistatic plastic composites of reliable mechanical and physical properties were got. The products were widely used in the electronics, chemicals and military products packaging which were sensitive to electrostatic and electromagnetic radiation. The material also showed good static, electromagnetic and mechanical and physical protection.
