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,探讨了其对喷绘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,其含量越高,抑制作用越明显,但含量超过20份(质量份,下同)时,PVC膜的力学性能和喷绘性能下降。纳米SiO2和纳米CaCO3还可提高喷绘PVC膜的油墨吸收速度;但当团聚颗粒较大时,对PVC膜的喷绘性能会产生不利影响。
The influence of nano-CaCO3 and nano-SiO2 on the printing performance of PVC films 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 contents of nano-particles, the more effective of the anti-migration and the printing ink absorption ability of the film was improved. The contents of the nano-particle should be below 20 phr, otherwise the mechanical properties and printing performance of PVC films would decrease. The agglomeration of the nano-particles was harmful to the printing property of PVC films.
