中文摘要:
      目的 研究常见类型添加剂对BOPP(双向拉伸聚丙烯)薄膜表面光泽度和雾度的影响。方法 通过测试BOPP薄膜的表面光泽度、雾度,对比分析不同类型添加剂对BOPP薄膜光学性能的影响。 结果 氢化石油树脂与芯层PP有良好的相容性,有利于改善BOPP薄膜的表面光泽度和透明性,质量分数为5%~20%的氢化石油树脂可以使BOPP薄膜的光泽度由88%提高到95%,雾度由1.7%降至0.8%,增透效果明显。抗静电剂(烷基二乙醇胺、单甘酯)和爽滑剂(硅酮类、芥酸酰胺)与PP有部分相容性,在迁移过程中不同程度地影响了BOPP薄膜的光学性能。在烷基二乙醇胺与单甘酯复配的抗静电体系中,烷基二乙醇胺的添加有利于BOPP薄膜光学性能的提高,单甘酯含量的提高明显恶化了薄膜的光学性能,芥酸酰胺的添加造成BOPP薄膜光泽度下降,雾度增加,苯基改性硅酮比普通硅酮更有利于提高BOPP薄膜表面的光泽度与透明性。抗粘连剂二氧化硅与表层PP不相容,形成了界面,在二氧化硅含量大于0.15%(质量分数)时,雾度迅速提高,光泽度下降。结论 薄膜生产配方中添加剂的选择与优化是开发高表面光泽度低雾度BOPP薄膜的关键。
英文摘要:
      The work aims to study the effects of common additives on the surface gloss and fog of BOPP (biaxially oriented polypropylene) films. The effects of different types of additives on the optical properties of BOPP film were compared and analyzed by measuring the surface gloss and fog of BOPP films. It was found that hydrogenated petroleum resin had good compatibility with PP and was beneficial to improve the surface gloss and transparency of BOPP films. 5%-20% (mass fraction) hydrogenated petroleum resin could increase the gloss of BOPP film from 88% to 95%, and decrease the fog from 1.7% to 0.8%. The transparency enhancement effect was obvious. Antistatic agents (alkyl diethanolamines, monoglycerides) and slipping agents (silicones, erucic amide) had partial compatibility with PP, and the optical properties of BOPP films were affected to varying degrees during migration. In the antistatic system composed of alkyl diethanolamine and monoglyceride, the addition of alkyl diethanolamine was conducive to improving the optical properties of BOPP films, the increased content of monoglyceride significantly worsened the optical properties of the films, and the addition of erucic amide also caused the gloss of BOPP film to decrease and the fog to increase. Phenyl modified silicone was more advantageous to improve the surface gloss and transparency of BOPP film than ordinary silicone. The interface of anti-blocking agent silicon dioxide and surface PP was produced due to their incompatibility. When the content of silicon dioxide was more than 0.15% (mass fraction), the fog increased rapidly and the gloss decreased. Selection and optimization of additives in film formulation are the keys to develop BOPP films with high surface gloss and low fog.
