摘要:
以邻苯二胺、三氯氧磷和三聚氰胺为原料经过两步反应合成了一种三聚氰胺基含磷的膨胀型阻燃剂(DPMA),并通过傅里叶红外光谱、核磁共振、热重等测试方法分析了产品结构和性能,结果表明DPMA在800?°C有23.7%的残炭量,热稳定性良好。DPMA与尼龙6熔融共混制备阻燃复合材料,并对其热稳定性能、成炭性能和力学性能进行测试与分析。分析结果表明,当DPMA的添加量为20%时,复合材料在800 ℃时的残炭量从0.07%增加到6.95%,残炭层有更高的石墨化程度和更加致密、规整的微观结构;质量分数5%的DPMA可以使PA6的力学性能有明显的提升,DPMA分子与PA6有良好的相容性且无明显的团聚和表面迁移现象。
Abstract:
A melamine-based phosphorus-containing intumescent flame retardant (DPMA) was synthesized using o-phenylenediamine, phosphorus oxychloride and melamine as the raw materials by two-step reaction. The chemical structure and properties were confirmed by Fourier transform infrared spectroscopy, nuclear magnetic resonance and thermogravimetric analysis. The residual carbon content of DPMA was 23.7% at 800 ℃ and good thermal stability was obtained. Then, DPMA was added to polyamide 6 (PA6) to prepare flame retardant composites by melting blending with the investigation of its thermal stability, char forming and mechanical properties. The results show that when the amount of DPMA added is 20%, the residual char of PA6 composite increases from 0.07% to 6.95% at 800 ℃, and the char layer exhibits more continuous and compact microstructure with higher graphitization degree. In addition, 5% DPMA can significantly improve the mechanical properties of PA6. DPMA could mix well with PA6 substrate without obvious surface migration and agglomeration.
