Organophosphorus zinc borate flame retardant include halogen-containing phosphate cool, cool halogen-containing phosphorous, non-halogen and phosphorous acid vinegar vinegar. Both as a flame retardant phosphate plasticizer vinegar, vinegar phosphite heat stabilizer both as a flame retardant effect.
When the organic phosphorus flame retardants are added to the polymer material, partial decomposition when heated polyphosphate. Segregation dehydration with a strong acid, the polymer material is formed on the surface char-combustion, the carbonized polymer film is cut off from direct contact with the material surface and the air of combustion, so that the flame is extinguished.
