| 摘 要：采用乙烯-甲基丙烯酸甲酯共聚物（EMMA）作為增容劑制備了回收聚乙烯／聚氯乙烯（RPE／PVC）共混材料。通過(guò)差示掃描量熱儀（DSC）研究了共混材料兩相之間的相容性；通過(guò)微控電子萬(wàn)能實(shí)驗機、電子沖擊實(shí)驗機研究了EMMA和RPE對共混材料性能的影響。DSC試驗結果表明，EMMA能顯著(zhù)改善PVC與RPE之間的相容性，使共混材料中PVC的玻璃化轉變峰變寬且變得模糊；力學(xué)性能試驗結果表明，加入3份EMMA時(shí)，RPE／PVC（10／100）共混材料的沖擊強度、拉伸強度、彎曲強度和彎曲模量分別提高了270%、74%、60.9%和9.1%；隨著(zhù)RPE含量的增加RPE／PVC共混材料的力學(xué)性能下降，當EMMA含量為3份、RPE含量為10份時(shí)，共混材料的綜合性能較佳。 |

| Abstract：Recycled polyethylene （RPE）／PVC blends using ethylene-methyl methacrylate copolymer （EMMA） as the compatibilizer were prepared. The compatibility of RPE／PVC blends was characterized using differential scanning calorimeter（DSC）. Effects of EMMA and RPE on mechanical properties of RPE／PVC blends were studied using micro-controlled electronic universal testing machine and electronic impact testing machine. The experimental results of DSC indicated that the compatibility between PVC and RPE was apparently improved due to the addition of EMMA，the glass transition became blurred. The experimental results of mechanical properties showed that，the impact strength，the tensile strength，the flexural strength and flexural module of RPE／PVC blends were respectively improved by 270%，74%，60.9% and 9.1% at an EMMA loading of 3 phr compared to control sample. The mechanical properties of blends were decreased with the increasing of RPE content. When the content of EMMA and RPE was respectively 3 phr and 10 phr，the mechanical properties of RPE／PVC blends were the best. |
