Abstract
The present invention relates to the field of IPC C08L69, and more specifically relates to a chemical-resistant polycarbonate composition and a preparation method therefor. The composition includes 15-30 parts of a polycarbonate-polysiloxane copolymer, 50-90 parts of a bisphenol A polycarbonate, 20-40 parts of a polycarbonate master batch, and 0.01-0.1 part of an additive; and the composition includes the polycarbonate-polysiloxane copolymer having a ratio of a polysiloxane block of 15-30 wt %. By adding an organic silicon composition SFR 100, a polycarbonate material can be obviously improved in resistance to corrosion of chemical agents without cracking, which can be applied to medical treatment and electronic equipment. An E value (polymerization unit) is 40-100, and a proportion of the polycarbonate-polysiloxane copolymer in the composition is greater than 17.5 wt %, such that chemical resistance of the composition can be maintained, and a residual elongation at break can be maintained between 80% and 139%.
