摘　　要：将马来酸单酯稀土(RETM)热稳定剂用于PVC自粘保鲜膜中,并对其成膜性、粘附性、透明性、防雾性等进行了研究,结果表明:马来酸单酯稀土热稳定剂能改善PVC的塑化均匀性,提高熔体强度,改善自粘膜的成膜性。采用马来酸单酯稀土热稳定剂自粘膜的粘附性、防雾性比采用京锡8831要好,而透光性与京锡8831基本相当,因此可以代替昂贵的有机锡热稳定剂在PVC自粘保鲜膜中应用。Using RETM as a kind of stabilizers for PVC self-adhesive retaining freshness film, and the film forming property,adhesive power, transparency and anti-fog property were studied. The result showed that RETM could improve the plasticizing quality of PVC,raise the strength of melting and improve the film forming property as well. RETM compared with JingXi-8831 ,it＇s adhesive power and anti-fog property were better, and transparency was same around. Then RETM was substitute for high-priced organic-tin thermo-stabilizer in PVC self-adhesive retaining freshness film.
