摘要: 用纳米SiO2和纳米CaCO3来抑制喷绘用聚氯乙烯(PVC)膜中增塑剂的析出,并探讨了纳米SiO2和纳米CaCO3对喷绘PVC膜喷绘性能的影响。结果表明,纳米CaCO3和纳米SiO2可以有效抑制喷绘PVC膜中增塑剂的析出,纳米无机粒子含量越高,其抑制作用越明显,但纳米无机粒子含量超过20份时,PVC膜的力学性能和喷绘性能下降;纳米无机粒子提高了喷绘PVC膜的油墨吸收速度;当纳米SiO2和纳米CaCO3团聚颗粒较大时,对PVC膜的喷绘性能产生不利影响。

Abstract: The influence of nano-CaCO3 and nano-SiO2 on the printing performance of PVC film were studied. It was found that nano-CaCO3 and nano-SiO2 could reduce the migration of plasticizers from the PVC film, the higher of the content of nano-particles, the more effective of the anti-migration and the printing ink absorption ability of the film was improved. The content of the nano-particle should be below 20 phr, otherwise the mechanical properties and printing performance of PVC film would decreased. The agglomeration of the nano-particles was harmful for the printing property of PVC film.

Key words: nano-silica, nano-calbonate, plasticizer, migration, poly(vinyl chloride), printed film
