DOPO及其衍生物在聚合物中的应用研究进展

摘要

9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO)is an organic phosphorus-based flame retardant,featuring high thermal stability and excellent resistance to water. It has been widely usedfor polymer modification of flame retardance and water-resistance. This paper provides an overview of the structure,preparation processes and application of DOPO and its derivatives in improving flame retardance of polymers such as epoxy resins,polyester,polycarbonate and polyamide,moreover,thermal stability and mechanical properties of epoxy resinsare also enhanced. The application of epoxy resin is widened with the good comprehensive properties. In a result with the addition of DOPO or its derivatives,the flame retardancy as well as the water resistance of polyester are improved. With the addition of DOPO or its derivatives,the level of flame retardance of polycarbonates and polyamides can be increased to V-0.%9,10-二氢-9-氧-10-磷杂菲-10-氧化物（DOPO）是一种含磷的有机阻燃剂，具有热稳定性高、耐水性优良等特点，被广泛应用于高分子材料的阻燃、耐水解改性等。综述了DOPO及其衍生物的结构、制备方法，以及在环氧树脂、聚酯、聚碳酸酯、聚酰胺等高分子材料中的应用研究进展。DOPO加入环氧树脂、聚酯、聚碳酸酯、聚酰胺等高分子材料中可改善其阻燃性，同时还改善了环氧树脂的力学性能和热稳定性，获得综合性能优良的环氧树脂复合材料，拓宽了环氧树脂的用途。DOPO或其衍生物加入聚酯中，可有效改善聚酯的阻燃性及耐水性能。DOPO或其衍生物加入到聚碳酸酯和聚酰胺中，可使聚碳酸酯和聚酰胺的阻燃等级提高到V-0级。
