Abstract

In the article proposes new compositions based on fire retardant expanded polymer composites of epoxy resin ED-20 and phosphorus-containing oligomers, catalysts, aluminum hydroxide and nitrogen-containing compounds.

The obtained sample of fire retardant expanded polymer composites based on epoxy resin, as well as the initial substances, were investigated by IR spectroscopy (Nicolet 5700), thermogravimetric analysis (TG) (SDT Q600) of physical and chemical properties and determination of fire retardant efficiency according to GOST R 53295-2009.

Infrared spectroscopy has been used to determine the bends and epoxy groups that characterize composites, as well as to determine the frequencies of phosphorus, nitrogen, and metal-containing groups. At the same time, a thermal analysis of the obtained composites was carried out. The TG analysis analyzed temperatures in the range 150-500 oC and a weight loss of 3% was determined at 150 oC, weight at 430 oC, weight at 430 oC, 430 oC orat at 150 oC. 50%.

Composites DTA derivatograms are protective expanded polymer composites based on epoxy tar, four endothermic effects at 175, 186, 200 and 430 ops and three exothermic effects of 250 or 300 and more than 400 effects were found. According to the results of a study of the fire resistance of polymer composite coatings obtained on the basis of GOST R 53295-2009, it was found that they meet the requirements of GOST. It has been established that, in contrast to polymer composites, they have the property of protection against three different types of impacts in the same time.
