摘要本实验的设计思想是将含磷阻燃剂与含卤阻燃剂进行复配混合，从中选出能够使环氧树脂阻燃效果达到最佳的磷-卤复合阻燃剂302的配方。阻燃性能的研究方法为水平燃烧法以及极限氧指数法。样品燃烧残留物的微观形态结构与化学结构可以通过扫描电镜和红外光谱进行分析，阻燃复合材料的热稳定性通过热重法研究。63850
配方中增大复合阻燃剂320的配比，使得FREP的阻燃性能得到提高。根据实验数据可以发现，当阻燃剂320的含量达到15%时，FREP的阻燃性能良好，燃烧级别为FH-1，加入的阻燃剂对材料力学性能、弹性模量、冲击强度、拉伸强度等产生影响。经过对比，加入阻燃剂的材料各项性能指标均随着阻燃剂加入的量而降低。当加入的阻燃剂的量为18%时，测试FREP，得到的数据显示拉伸强度降低了24.5%，弹性模量降低了32.1%，冲击强度降低了57.4% 。

Title Preparation and Properties of epoxy flame retardant composite
Abstract In this paper,the main idea is to mix phosphorus-containing flame retardants and halogen-containing flame retardants. Choose the epoxy resin flame-retardant effect of optimal phosphorus - halogen composite flame retardant formulation 302. The flame-retardant properties of the horizontal combustion method and limiting oxygen index. The sample combustion residues microscopic morphology and chemical structure analysis by scanning electron microscopy and infrared spectroscopy, flame-retardant composite thermal stability by thermal gravimetric analysis.
Flame-retardant properties are improved formula increases the ratio of the composite flame retardant, making the FREP. According to the experimental data can be found, reach 15% when the content of the flame retardant to 320 FREP good flame retardant properties, combustion level for FH-1, The flame retardants Add impact on the mechanical properties of materials, elastic modulus, impact strength, tensile strength, etc. By comparison, adding flame retardant material the performance indicators are reduced as the amount of flame retardant added. When the added amount of the flame retardant was 18%, the test FREP The obtained data show that the tensile strength is reduced by 24.5%, and 32.1% reduction in elastic modulus, impact strength is reduced 57.4%.
