无溶剂复合PE膜摩擦系数性能分析及应用
|
摘要
以无添加的低密度聚乙烯作为载体树脂,加入无胺爽滑剂、开口剂和抗氧化剂制成爽滑母料,然后添加一定比例的爽滑母料吹塑成PE热封膜,并对其进行无溶剂复合,研究了PE膜在复合及熟化后摩擦系数的变化。结果表明,在无溶剂复合过程中PE热封膜的摩擦系数始终保持在0. 15～0. 25,并且在40℃以内的熟化温度下,摩擦系数几乎保持不变,同时复合膜的热封强度保持在63 N/15 mm以上,剥离强度保持在2. 2 N/15 mm以上,60μm PE热封膜的透光率和雾度分别为90. 8和0. 23,与相同厚度的普通PE膜的差距较小,完全符合GB/T 10004—2008中薄膜性能的要求,解决了采用胺类爽滑剂母料导致无溶剂复合产品摩擦系数变大的现象。
No amine slip agent,opening agent and antioxidant were added to no adding LDPE to granulate slipper masterbatch,and PE blown film was produced with a certain proportion slipper masterbatch,and the PE film was performed by solvent-free compounding. The change of the friction coefficient with solvent free composite was tested. Results showed that the friction coefficient kept at 0. 15 ～ 0. 25 within the 40 ℃ ripening temperature and the heat sealing strength of the film membrane kept above 63 N/15 mm,the peel strength kept above 2. 2 N/15 mm,and the transparency and haze with 60 μm PE film were 90. 8 and 0. 23,they were the same as the normal thickness of the PE. The PE film for solvent free compsite fully meeted the requirements of GB/T 10004—2008 film performance,and solved the phenomenon that the friction coefficient of the solvent-free composite product increases with the use of amines slip agent masterbatch.
