摘要:

以三聚氰胺和磷酸为原料, 采用溶剂热方法合成出纳米三聚氰胺磷酸盐(NMP)阻燃剂。用傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、扫描电镜(SEM)等手段表征产物的组成和结构, 研究了不同溶剂(蒸馏水、无水乙醇和苯)、不同类型的表面活性剂(十二烷基硫酸钠(SDS)、十六烷基三甲基溴化铵(CTAB)、壬基酚聚氧乙烯醚(NP))、以及反应温度和反应时间对产物形貌的影响。结果表明: 只有使用苯为溶剂才能合成出NMP, 表面活性剂的种类对产物的形貌有较大的影响。将合成的NMP与市售的微米级MP(MMP)在增韧酚醛泡沫中的阻燃性能和力学性能对比, NMP阻燃增韧酚醛泡沫的弯曲强度比MMP阻燃增韧酚醛泡沫提高了39%。

Abstract：

Nano melamine phosphate (NMP) flame retardant was synthesized using melamine and phosphoric acid as reagents by means of a solvothermal method. The prepared NMP was then characterized by means of Fourier transform infra-red spectroscopy, X-ray diffraction, and transmission electron microscopy. Effect of solvents, different kinds of surfactants (i.e. SDS, CTAB and NP), reaction temperature and time on the morphology of reaction product was investigated. It is found that the NMP can only be obtained by using benzene as a solvent. If distilled water and anhydrous ethanol were used as solvent, the particle size of the product is in micro scale. As reaction temperature or reaction time increases, the morphology of the products changes greatly. Moreover, types of surfactants have a great influence on the morphology of the products. Moreover, The polyethylene glycol toughened phenolic foam with addition of NMP exhibits a flexural strength 39% higher than that with addition of micro MP.

Key words： organic polymer materials material synthesis nano melamine phosphate solvothermal method phenolic resin
