摘要:

为提升聚乙烯/聚丙烯(PE/PP)覆膜非织造布的抗静电性能,通过高分子抗静电剂与改性松香树脂热熔胶共混制备抗静电复配热熔胶,并将其用于PE/PP非织造布的喷胶覆膜加工。分析了复配热熔胶的热稳定性以及抗静电剂添加量对其熔融黏度的影响,并对比测试了复配胶对PE/PP覆膜非织造布抗静电性能的影响规律。结果表明:随着高分子抗静电剂质量分数的增加,复配胶熔融黏度逐渐降低后趋于稳定;复配胶在高温区的热稳定性下降,但熔融状态下的热稳定性不受影响;复配胶可向PP非织造布、PE膜基体及其外表面渗透,构筑电荷转移与泄漏网络,从而提升覆膜非织造布的抗静电性能,且抗静电性能的提升与复配胶中抗静电剂的质量分数成正相关;经5次水洗后,PE/PP覆膜非织造布仍具有一定的抗静电性能。

Abstract:

In order to improve the antistatic property of polyethylene/polypropylene(PE/PP) coated nonwoven fabric, the antistatic composite hot melt adhesive (composite adhesive) was prepared by blending the macromolecule antistatic agent with the modified rosin resin hot melt adhesive, and used for the spray-coating process of PE/PP nonwoven fabrics. The effect of the amount of antistatic agent on the melt viscosity of the composite adhesive was discussed, and its thermal stability was analyzed as well. Then, the influence of the composite adhesive on the antistatic property of the coated nonwoven fabrics was tested and compared. The results show that with the increase of the antistatic agent concentration, the melt viscosity of the composite adhesive will gradually decrease and then stabilize. The thermal stability of the composite adhesive decreases in the high temperature zone, but it is not affected in the melt state. The charge transfer and leakage network is constructed by the penetration of the composite adhesive into PP nonwoven, PE film and their outer surfaces, which improves the antistatic property of the coated nonwoven fabric. The improvement of the antistatic property is positively correlated to the concentration of antistatic agent in the composite adhesive. A certain antistatic property of coated nonwoven fabric is maintained after washing for 5 times.

Key words: antistatic, hot melt adhesive, polyethylene, polypropylene, coated nonwoven fabric
