马来酸单酯稀土在PVC自粘保鲜膜中的应用

将马来酸单酯稀土热稳定剂用于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的自粘膜的粘附性、防雾性比采用京锡8831的好,而透光性与京锡8831的基本相当。因此,在PVC自粘保鲜膜应用中可代替昂贵的有机锡热稳定剂。

Study on Application of RETM in PVC Self-Adhesive Retaining Freshness Film

Using RETM as a kind of stabilizers for PVC self-adhesive retaining freshness film,the film forming propertyies,adhesion,transparency and anti-fog properties are studied.The results show that RETM can im- prove the plasticizing quality of PVC,raise the strength of melting and improve the film forming property as well. Compared with JingXi-8831 using RETM as a stabilizer,its adhesion and anti-fog property is better,and trans- parency is same around.RETM can be substitute for high-priced organic-tin thermo-stability in PVC self-adhe- sive retaining freshness film.
