Abstract

The burning of Ethylene-Propylene-Diene Monomer (EPDM) rubber generates substantial smoke, posing a severe threat to the environment and personal safety. Considering the growing emphasis on safety and environmental protection, conventional non-smoke-suppressing flame retardants no longer satisfy the present application requirements. Consequently, there is an urgent need to develop a novel flame retardant capable of suppressing smoke formation while providing flame retardancy. Sepiolite (SEP), a porous silicate clay mineral abundant in silica and magnesium, exhibits notable advantages in the realm of flame retardancy and smoke suppression. This research focuses on the synthesis of two highly efficient flame-retardant smoke suppression systems, namely AEGS and PEGS, using Enteromorpha (EN), graphene (GE), sepiolite (SEP), ammonium polyphosphate (APP), and/or piperazine pyrophosphate (PPAP). The studied flame-retardant systems were then applied to EPDM rubber and the flame-retardant and smoke suppression abilities of EPDM/AEGS and EPDM/PEGS composites were compared. The findings indicate that the porous structure of sepiolite plays a significant role in reducing smoke emissions for EPDM composites during combustion.

摘要

三元乙丙橡胶（EPDM）燃烧会产生大量烟雾，对环境和人身安全构成严重威胁。鉴于对安全和环境保护的日益重视，传统的无抑烟功能的阻燃剂已无法满足当前的应用需求。因此，迫切需要开发一种新型阻燃剂，既能抑制烟雾形成又具备阻燃性能。海泡石（SEP）是一种富含硅和镁的多孔硅酸盐粘土矿物，在阻燃和抑烟领域具有显著优势。本研究聚焦于利用浒苔（EN）、石墨烯（GE）、海泡石（SEP）、聚磷酸铵（APP）和/或焦磷酸哌嗪（PPAP）合成两种高效的阻燃抑烟体系，即AEGS和PEGS。随后将所研究的阻燃体系应用于EPDM橡胶，并比较了EPDM/AEGS和EPDM/PEGS复合材料的阻燃和抑烟能力。研究结果表明，海泡石的多孔结构在降低EPDM复合材料燃烧过程中的烟雾排放方面发挥着重要作用。
