摘 要:以乙烯-甲基丙烯酸甲酯共聚物(EMMA)為增容劑制備了聚氯乙烯(PVC)/聚丙烯(PP)復合材料,采用DSC表征了復合材料的相容性,用WDW3020微控電子萬(wàn)能實(shí)驗機、XCJ-40電子沖擊實(shí)驗機測試了復合材料的力學(xué)性能;并與氯化聚乙烯(CPE)增容PVC/PP共混體系進(jìn)行了比較。試驗結果表明:EMMA能顯著(zhù)改善PVC與PP的相容性。當增容劑用量為9份時(shí),與未增容PVC/PP體系相比,缺口沖擊強度,拉伸強度和彎曲強度分別提高了191%,70%,41%;與CPE增容PVC/PP體系相比,缺口沖擊強度,拉伸強度和彎曲強度分別提高了44%,39%,12%。

Abstract:PVC/PP composites using ethylene-MMA co-polymer(EMMA)as the compatibilizer were prepared. The compatibility of PVC/PP composites were characterized by means of different scanning calorimeter(DSC). The mechanical properties of PVC/PP composites were tested using WDW3020 electronic universal testing machine and XCJ-40 electronic impact testing machine. Furthermore,the difference between EMMA and chlorinated polyethylene(CPE)as compatibilizer for PVC/PP composites was also investigated. The experimental results have shown that the compatibility between PVC and PP were apparently improved due to the addition of EMMA. Compared with pure PVC/PP composites,when 9 phr EMMA were added,the notch impact strength,tensile strength and flexural strength of PVC/PP composites were improved by 191%,70% and 41%,respectively. Whereas compared with PVC/PP composites using CPE as compatibilizer,the notch impact strength,tensile strength and flexural strength were improved by 44%,39% and 12%,respectively.
