Rubber flame retardants based on organophosphorus compounds

Abstract

In the work presented oxyethylidenediphosphonic acid and its ammonium salt were proposed as rubber flame retardants and rubber formulations were elaborated. The effect of the flame retardant additives on the mechanical properties of rubber was studied, and the degree of fire protection was determined. It was shown that the rubber with the addition of oxyethylidenediphosphonic acid had a higher degree of fire resistance compared to the rubber with oxyethylidenediphosphonic acid ammonium salt.
