| abstract |
The invention discloses an organic synthetic flame retardant polycarbonate material and a preparation method thereof. The preparation method comprises dihydroxy compound, carbonic acid diester, tetrabromophthalate di(2-ethylhexyl) ester, zinc borate As raw material, non-phosgene melt transesterification method is adopted under the action of basic ionic liquid. The invention can not only significantly improve the flame retardancy of the material (the oxygen index can reach 45%), but also maintain or even improve other properties of the material, such as thermal stability, electrical insulation, color stability, flexibility and the like. |
