| 目的 研究自制山梨醇类成核剂对BOPP烟膜表面耐磨性能的影响。方法 利用山梨醇类及其复配自制的成核剂，通过对比试验研究成核剂对烟膜力学性能的影响；对BOPP烟膜表面热封层进行耐磨性能改性，随后开展耐擦伤性能检测试验，通过平板上薄膜雾度变化来衡量耐磨性能。结果 山梨醇类及其复配自制成核剂能明显改善烟膜的力学性能，尤其在硬度方面效果显著；与无添加成核剂的膜相比，当成核剂质量分数为0.2%时，烟膜热封层的邵氏硬度提高了近22.7%；经摩擦后，成核剂改性后烟膜的雾度提高了33.1%；此外，成核剂的加入对烟膜其他性能指标影响不大，也不需要对生产工艺做特别调整。结论 研制的BOPP烟膜成核剂可以提高共聚PP薄膜的表面硬度，并在一定程度上改善了BOPP薄膜表面的耐擦伤性能。 |

| The paper aims to study the effect of nucleating agent on the scratch resistance of BOPP for cigarette package. The effect of nucleating agent on BOPP for cigarette package with sorbitol and its compound on mechanical properties was studied by comparison experiment. The thermal seal of BOPP was modified, and then the scratch resistance was tested to indicate the scratch resistance through the change of the haze value of film on the plate. The sorbitol nucleating agent and its compound could apparently increase the mechanical properties of the film, especially in hardness, which was increased by nearly 22.7 % with the nucleating agent being 0.2%, and the haze value was decreased by 33.1% compared with those of vigin BOPP, and there was no much change on other properties, which was no need to make special adjustments to the production process. The nucleating agent researched for BOPP can increase the hardness of PP film and improve the scratch resistance of BOPP film. |
