CPE白炭黑共混改性研究.doc

2009级应用化学专业毕业论文I论文题目:CPE/白炭黑共混改性研究摘要:本课题采用白炭黑作为填料,通过机械共混法制备改性后的CPE,考察了白炭黑用量对PVC力学性能的影响。研究了材料的拉伸性能,材料硬度,回弹性测试等。结果表明随着白炭黑含量的增加,回弹性逐渐减小,拉伸强度先变大后变小,硬度随CPE的含量的增加硬度逐渐变小。关键词:***化聚乙烯;白炭黑;机械共混;拉伸强度;回弹性;洛氏硬度许盼成:CPE/白炭黑共混改性研究IITitle:CPE/silicablendsModificationAbstract:Thissubjecttakessilicahydratedasfiller,makesmodifiedCPEbymechanicalblendingmethod,,hardness,,theresilienceofthematerialgraduallydecreases,thetensilestrengthincreasesatfirstandthendecreases,:chlorinated;polyethylene;silicahydrated;mechanicalblending;tensilestrength;Rockwellhardness2009级应用化学专业毕业论文III目录摘要.........................................................................................................................................IAbstract......................................................................................................................................II1绪论................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
