Abstract
Despite the small share of nanoparticles in the chemical industry, the demand for modifiers is growing every day. This is due to their high physical, mechanical and operational properties, resistance to aggressive media, and ability to be used over a wide temperature range. According to the results of this study, introducing metal phosphates into the polymer improves the physical and mechanical properties of polyolefins. The physico-mechanical properties of the obtained polymer composite materials were improved up to 1-2 times compared to the initial polyethylene, polypropylene and polyamide-66 samples without filling. As a result of the addition of fillers, the elasticity, impact and fire resistance of polymers increased up to 2 times. Therefore, it is more important to produce polymer materials based on metal-containing compounds and apply them in practice. Including metal phosphates among the fillers increases the fire resistance of the composites. The rate of polymer liquefaction was determined by SOK(PTR) method. Also, IR, thermal analysis, TG and DTA, DSK, SEM and EDS analysis, X-ray diffraction, burning time and oxygen index were determined. As a result of the introduction of fillers, polymer molecules are bound with metal binders, and the elasticity, impact and fire resistance, and heat resistance of polymers have increased up to 2 times. The combustion time was reduced from 239 C to 125 C, and an increase in the oxygen index from 19% to 26% was achieved.
