摘要
以新型离子液体型抗静电剂对热熔性压敏胶进行抗静电改性,将改性后的热熔性压敏胶与LDPE基材通过三层共挤吹膜成型高黏共挤抗静电保护膜,研究了离子液体含量与热熔性压敏胶的加工性能、高黏共挤抗静电保护膜表面电性能、力学性能之间的定量关系。结果表明,离子液体的加入,可以明显的降低高黏共挤保护膜的表面电阻,在离子液体含量为4%时,表面电阻为(1.0~9.9)×10^(10)Ω/□,撕膜电压小于200 V;离子液体对热熔性压敏胶具有较好的增塑作用,离子液体对高黏共挤保护膜的力学强度(如180°剥离强度、拉伸强度)无明显的影响。研究的高黏共挤抗静电保护膜在电子产品制造领域有较大应用前景。
In this study,a new type of ionic liquid antistatic agent was employed to antistatic modification on the hot melt pressure-sensitive adhesive.The modified hot melt pressure-sensitive adhesive and low density polyethylene(LDPE)base material were processed by a 3-layer co-extrusion blown technique to form a high-viscosity co-extrusion antistatic film.The quantitative relationship among the content of the ionic liquid and the processing,electrical and mechanical properties of the high-viscosity co-extrusion film was studied.The results show that the addition of ionic liquid can significantly reduce the surface resistance of the protective film.When the ionic liquid content is 4%,the surface resistance is(1.0~9.9)×10^(10)Ω/square,and the peeling voltage is less than 200 V.The ionic liquid has good plasticizing effect on the hot melt pressure-sensitive adhesive,and has no obvious effect on the mechanical strength(such as 180°peeling strength and tensile strength)of the protective film.The protective film has great application prospects in the field of electronic product manufacturing.
