Sažetak
Flame retardancy has been imparted through the addition of organophosphorus agent which enhances paper utilization and increases the value of paper products. For that purpose paper was impregnated with solution of flame retardant agent, binder and its catalyst and linked during the curing step. N-hydroxymethyl-3-dimethylphosphonpropionamide was used as organophosphorus flame retardant (FR) agent with two types of binders, either melamine formaldehyde or citric acid. The use of bonding agent is necessary in order to form covalent linkages between FR agent and cellulose macromolecules. First binder type implements etherification mechanism which requires phosphoric acid for the catalysation. Second binder type implements esterification mechanism which requires phosphono based catalysts. Citric acid represents new class of environmentally friendly agents, and as such is recommended for the usage. Non-durable flame retardant based on boron compounds was used in a study as comparison. Flame retardancy was tested according to ISO 6940 and 6941 method, so as with limiting oxygen index (LOI) technique, according to ASTM D 2863-97 while the tensile indices were measured according to the ISO 1924– 2.
