Flame retardant oil modified chlorinated alkyd Resins

Abstract

Fire retardant oil‐modified alkyd resin based on chlorendic ahnydride (1,4,5,6,7 7‐hexachlorobicyclo‐(2,2,1) hept‐5‐ene‐2,3‐dicarboxylic anhydride) have been synthesized using linseed oil, phthalic anhydride and glycerol. Several paint formulations were designed to study the effect of pigment/binder ratio, antimony trioxide and chlorinated thermosetting and thermoplastic polymers on fire retardancy. Oxygen index method was used to evaluate the fire retardancy of paints. The chlorinated alkyd resin was used as a plasticizer for laroflex MP 35 to improve the fire retardancy of the thermoplastic chlorinated polymer.
