摘要

以3-三乙氧基基-1-丙胺（KH550）、9,10-二氢-9-氧-10-磷-10-氧甲基（DOPO）和水杨醛为原料，利用Kabachnik-Fields反应成功合成了新型阻燃剂N， N-二（2-羟基苯基-9,10-二氢-9-氧-10-磷-10-氧-甲基）-丙基三乙氧基硅烷（KDS）。采用傅里叶变换红外光谱（FTIR）和热重分析（TGA）对KDS的结构和偏好进行了表征。当KDS添加量为30%时，ubr -30的阻燃性能较好。它达到了UL-94V-0等级，极限氧指数（LOI）高达27.2%，峰值放热率（PHRR）和总放热率（THR）分别降低了71%和63%。最后，采用了多种测试技术来考察KDS可能的阻燃机理。

A novel flame retardant based on Kabachnik-Fields reaction applied to fire retardant the unsaturated polyester resin

The Kabachnik-Fields reaction was employed to successfully synthesize a novel flame retardant, N, N-bis (2-hydroxyphenyl-9,10-dihydro-9-oxa-10-phosphame-10-oxy-methyl)-propyltriethoxy-silane(KDS), using 3-triethoxysilyl-1-Propanamine (KH550), 9, 10-dihydro-9-oxa-10-phosphophenanthrene 10-oxide (DOPO) and salicylaldehyde as raw materials. Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA) were employed to characterize the structure and preference of KDS. The composite UPR-30 exhibited superior flame retardancy when KDS was added at a rate of 30 %. It achieved a UL-94V-0 rating, a high limiting oxygen index (LOI) of 27.2 %, and a 71 % and 63 % decrease in the peak heat release rate (PHRR) and total heat release rate (THR). Finally, a variety of testing techniques were adopted in order to examine the likely flame retardant mechanism of KDS.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
