Abstract
Despite the small share of nanoparticles in the field of chemistry, the demand for modifiers is increasing every day. This is due to their high physical, mechanical, and other mechanical properties, resistance to aggressive environments, and the ability to use them in a wide temperature range. According to the results of this study, the introduction of metal phosphates into the polymer improves the physical and mechanical properties of polyolefins. The physico-mechanical properties of the obtained polymer composite materials improved by 1-3 times compared to the initial polyamide-66 samples without filling. It is more important to produce polymer materials based on metal-containing compounds and to use them in practice. The inclusion of metal phosphates among fillers increases the fire resistance of composites. IR, thermal analysis, TG and DTA, DSK, Raman spectroscopy, X-ray diffraction, burning time, and oxygen index were also determined. As a result of the introduction of fillers, polymer molecules are connected with metal binders, and the elasticity, shock, fire resistance, and heat resistance of polymers have increased up to 3 times. The burning time is shortened, and the oxygen index is increased from 17% to 24%. At the same time, ammonium polyphosphate, an inorganic salt of phosphoric acid, was used as a filler, a widely used compound for the production of paints and varnishes with fire-resistant properties. These mineral fertilizers are high-molecular fire-resistant additives, the structure of which is formed as a result of combining monomeric orthophosphates into one polymer chain.
