摘要
采用静态热老化、脱氯化氢、动态热稳定实验研究了三羟甲基氨基甲烷(TRIS)与1,3-二甲基-6-氨基脲嘧啶(DMAU)作为聚氯乙烯(PVC)热稳定剂的协同作用。结果表明:DMAU与TRIS以2:1复配使用时,PVC具有最佳的静态和动态热稳定性能,并且优于季戊四醇与DMAU、二乙醇胺与DMAU协同使用的效果。
Using discoloration test, dehydrochlorination test and dynamic thermal stability test, the synergistic effects of 1,3-dimethyl-6-aminouracil （DMAU） and trihydroxymethyl aminomethane （TRIS） as polrvinyl chloride （PVC） thermal stabilizer were studied. The results indicate that： the best static and dynamic thermal stability of PVC are obtained, when the mass ratio of TRIS and DMAU is 2：1; it is better than the synergistic effects of pentaerythritol and DMAU, or diethanolamine and DMAU as synergistic thermal stabilizers.
