| 摘 要： | 本文以线性低密度聚乙烯/低密度聚乙烯（LLDPE/LDPE=3：1）为基材,添加具有防霉功能的OBPA（10,10’-氧代双吩恶砒,10,10’oxybis-phenoxarsine）,制备了厚度为0.016～0.017mm,浓度为0.00%、0.05%、0.10%、0.15%、0.20%和0.25%的OBPA防霉聚乙烯（PE）保鲜膜。结果表明：添加OBPA的保鲜膜抑制灰霉菌效果均达到QB/T2591-2003标准的1级水平;随着OBPA添加量的增多,断裂伸长率、拉伸强度和透明度不断降低,0.25%OBPA保鲜膜的断裂伸长率和拉伸强度分别比空白膜降低了14.84%和21.28%;添加OBPA能够增加保鲜膜的热合强度,0.25%OBPA保鲜膜比空白膜增加了27.92%;在8℃条件下对油菜保鲜12d,发现随着OBPA添加量的增多,0.25%OBPA保鲜膜包装的油菜的黄化率（9.43±0.07%）和失重率（1.00±0.04%）均较空白对照（分别为13.21±0.37%和1.32±0.07%）低。

| Abstract: | The LLDPE/LDPE （3：1） material was used as a substrate and OBPA（10,10＇oxybis-phenoxarsine） as an organic anti-mildew filler to improve the mildew proof of PE film. The thickness of 0.016-0.017mm anti-mildew polyethylene（PE）film added with various amount of OBPA including 0.00%, 0.05%, 0.10%, 0.15%, 0.20%and 0.25% were prepared. Results indicated that the samples with OBPA all meet the level 1 standard visibly based on the QB/T2591-2003. With increasing the amount of OBPA, the elongation at break rate, the tensile strength and transparency reduced gradually. And elongation at break rate and the tensile strength of 0.25%OBPA were lower than the blank film 14.84% and 21.28%, respectively. However, adding 0.25% OBPA can increase the heat sealing strength with 27.92% compared with control film. With increasing the amount of OBPA, the etiolation rate and the weightlessness rate were retained after preservation of rape for 12 days at 8℃. The etiolation rate（9.43±0.07%） and the weightlessness rate（1.00±0.04%） of 0.25%OBPA were lower than control （13.21±0.37%and 1.32±0.07% respectively）. |
