摘要

聚对苯二甲酸乙二醇酯(PET)因其优异的综合性能而在纤维、包装、电子电器等领域广泛应用，但其易燃性、低极限氧指数及熔滴行为限制了其在高阻燃安全等级领域的使用。PET的合金化改性通过引入酯类聚合物、非极性聚合物或橡胶弹性体等第二相，不仅使力学性能显著提升，还能改善阻燃剂分散性与作用效率，从而突破单一PET阻燃材料难以兼顾高强韧与高阻燃的性能瓶颈。本文重点总结了PET/酯类聚合物合金、PET/非极性聚合物合金及PET/橡胶弹性体合金在添加型与反应型阻燃改性方面的最新进展。结合现有研究，指出当前PET聚酯合金阻燃研究面临高阻燃–高强韧–低成本协同难题，未来应深化多相结构与阻燃机理耦合及界面限域阻燃研究，发展绿色高效阻燃剂及可工业化的合金化加工策略，以满足轨道交通、建筑构件及电子电器等领域的安全与功能需求。

Abstract

Poly(ethylene terephthalate) (PET) is widely used in fibers

packaging

electronics

and electrical appliances because of its excellent overall performance. However

its flammability

low limiting oxygen index

and melt-dripping behavior limit its application in areas that require high flame-retardant safety standards. The alloyingying modification of PET by introducing a second phase

such as ester-based polymenonpolarlar polymers

or rubber elastomers

this approach not only significantly improves the mechanical properties

but also enhances the dispersion and efficiency of flame retardants. This overcomes the performance bottleneck of single-component PET flame-retardant materials

which struggle to balance high strength-toughness and high flame retardancy. This article summarizes the latest progress in the additive and reactive flame-retardant modifications of PET/ester-based polymer alloys

PET/non-polar polymer alloys

and PET/rubber elastomer alloys. Existing research indicates that current flame-retardant studies on PET polyester alloys face challenges in synergistically achieving high flame retardancy

high strength-toughness

and low cost. Future efforts should focus on multiphase mechanism coupling and interface-confined flame retardancy

development of green and efficient flame retardants

and establishment of industrially viable alloying processing strategies to meet the safety and functional requirements of fields such as rail transportation

building components

and electronic and electrical appliances.
