High-tech flame-retardant polymeric materials based on EVA with dense compositions of fire-retardant fillers and a dispersing additive

The paper presents data on the creation of a high-tech, flame-retardant dispersed-filled polymer composite material (DFPCM) based on EVA grade 11306-075 and a dense composition mixture of flame retardants grades EP 20R and EP 2CA using a dispersant additive. The ratios of the components are calculated to obtain a dense composition of a mixture of EP 20R + EP 2C with a parameter φm equal to 0.68–0.72 v. Calculations of the compositions of DFPCM with different types of lattices and dispersed structures were carried out. The effect of the dispersing additive on the technological and physical-mechanical properties of DFPCM was shown. An optimal composition of high-tech, flame-retardant DFPCM based on CEVA and a mixture of EP 20R and EP 2SA brucites with a dispersing additive of the SPC 750U brand is proposed.
