titleOfInvention Low smoke and low heat intrinsic flame retardant copolycarbonate and preparation method and application
abstract The low-smoke and low-heat-release intrinsic flame-retardant polycarbonate disclosed in the present invention is composed of structural units represented by I, II and III, wherein the structural unit of II is 1-99% of the mole number of the structural unit of [I], [ III] is 0.5wt% to 20wt% of the mass of [I+II]; the copolycarbonate has a number average molecular weight of 12000 to 20000, a limiting oxygen index of 30.0 to 55.0%, and a vertical combustion grade of V-0; cone During the shape calorimetry test, the peak heat release rate is 40% to 90% lower than that of pure PC, and the total amount of smoke released is 10% to 90% lower than that of pure PC. The invention also discloses a preparation method thereof. The copolycarbonate in the invention has better effect of suppressing smoke heat release and higher carbon-forming properties, can effectively suppress the generation of melt droplets and reduce smoke heat release, and the preparation process is green and environmentally friendly. The obtained polymer has good injection molding performance, can be industrially produced, and can also be added to the polymer as a macromolecular flame retardant to achieve flame retardant.
