description The invention provides a polycarbonate resin composition for lampshades, which comprises 100 parts of polycarbonate, 0.1 to 0.5 part of chain extendor, 0.1 to 1.0 part of antioxidizer and 0.01 to 0.05 part of ultraviolet absorbent in parts by weight. The invention also provides a method for preparing polycarbonate resin by using the polycarbonate resin composition. Each component in the technical proposal has good compatibility, and the original molecular weight and the inherent viscosity of the polycarbonate can be increased and restored in the high-temperature shaping process under the synergic action of the chain extendor and the antioxidizer simultaneously; and the prepared polycarbonate resin has the advantages of high transparency, high impact strength, high bending strength and high tensile strength.
