Abstract

In order to create new epoxy resins with flame-retardant properties, we have synthesized a chlorine-containing epoxyimide resin. The required material has been prepared in two steps. The structure of the synthesized compound has been studied by infrared spectroscopy. The resin has been used to prepare a thermally stable epoxyimide composite with flame-retardant properties. The amount of the curing agent has been optimized using thermogravimetry: from weight loss data. The optimal amount of the curing agent in the epoxyimide composite has been determined to be 20 parts by weight for 100 parts by weight of the resin. The curing process requires no cure accelerator and occurs in the temperature range 56–128°C. Under optimal cure conditions, the degree of cure reaches 96%. The thermal properties of the epoxy composite and related coatings have been studied by differential thermal analysis and derivative thermogravimetry, and some of their physicomechanical properties have been investigated. The results demonstrate that the composite material based on the synthesized chlorine-containing epoxyimide resin has good physicomechanical properties, fire resistance, and sufficiently good thermal parameters compared to an ED-20 resin-based material.

耐火环氧酰亚胺树脂的合成

为了制备具有阻燃性能的新型环氧树脂，合成了一种含氯环氧酰亚胺树脂。所需材料已分两步准备好。用红外光谱对合成化合物的结构进行了研究。该树脂已用于制备具有阻燃性能的热稳定环氧酰亚胺复合材料。根据减重数据，利用热重法对固化剂的用量进行了优化。确定了环氧酰亚胺复合材料中固化剂的最佳用量为100份树脂的20份重量。固化过程不需要固化促进剂，发生在56-128℃的温度范围内。在最佳固化条件下，固化度可达96%。采用差热分析和导数热重法研究了环氧复合材料及其涂层的热性能，并对其部分物理力学性能进行了研究。结果表明，与ED-20树脂基材料相比，合成的含氯环氧酰亚胺树脂基复合材料具有良好的物理力学性能、耐火性能和足够好的热参数。
