摘　　要：以低分子量聚丙烯酸(PAA)共混改性聚丙烯(PP)制得1种具有阻垢效果的聚丙烯酸/聚丙烯(PAA-PP)复合塑料。以乙二胺四乙酸二钠(EDTA)络合滴定法评定PAA-PP复合塑料的阻垢性能,通过扫描电镜(SEM)观测塑料表面形貌并对CaCO_3垢样进行分析。结果表明:PAA-PP复合塑料具有良好的阻垢效果,1.55%PAA含量的PAA-PP复合塑料最高阻垢率达92.77%;在PAA-PP复合塑料表面,CaCO_3晶粒变小,不容易正常成核生长且规则有序地在其表面排列。Low-molecular weight polyacrylic acid （PAA） was used for blending modified poly-propylene （PP） to prepare polyacrylic acid/polypropylene composite plastics （PAA-PP）with scale inhibiting effect. By using the EDTA complex metric titration method, the scale inhibition performance of PAAPP composite plastics was investigated. The surface morphology of PAA-PP was observed by scanning electron microscopy （SEM）and the CaCO3 fouling sample was analysized. The results show that the PAA-PP composite plastics has good scale inhibiting effect, when the content of PAA is 1.55 %, the high scale inhibition rate can reach 92. 77%;The results show that the calcium carbonate scale grains become smaller and not easy to have nucleation growth and grow regularly and adhere on the surface of the PAA-PP composite plastics.
