Problems solved by technology

Although PC is a linear macromolecule, due to the large number of carbonyl groups and benzene rings in the molecular chain, the interaction force between PC molecular chains is strong, the entanglement is serious, and it is not easy to disentangle, which makes it difficult to produce molecular slippage under the action of external force. without deformation, the product size is stable

Abstract

A preparation method of the polycarbonate film comprises the following steps: 1) adding sepiolite into an aqueous solution of sodium dodecyl sulfate, then adding an aqueous solution of ferric chloride, pyrrole and ferric citrate, washing, drying, carrying out ball milling, and sieving with a 1000-mesh sieve to obtain sieved powder; 2) soaking the sieved powder in an aqueous solution of cerium trichloride and nickel dichloride, adding octadecyl trimethyl ammonium bromide, and calcining to obtain calcined powder; 3) soaking the calcined powder in an N, N-dimethylformamide solution of lipoic acid to form a mixture, and performing sealed heating, solid-liquid separation, washing and drying to obtain modified powder; and 4) carrying out melt blending on polycarbonate and the modified powder, carrying out extrusion granulation, and then carrying out injection molding and film drawing to form the polycarbonate film. The polycarbonate material prepared by the invention has good mechanical properties and certain heat resistance, the use effect of the polycarbonate body is obviously improved, the durability of the material is improved, and the use range of the film is widened.

Description

technical field [0001] The invention belongs to the technical field of polymer films, in particular to a polycarbonate film used for bags. Background technique [0002] Polycarbonate (PC) has excellent comprehensive performance, outstanding impact resistance, stable optical performance and good weather resistance. Various types of PCs with different properties including aliphatic, aromatic, and aliphatic-aromatic can be prepared according to the selection of polymerization process and raw materials. Although PC is a linear macromolecule, due to the large number of carbonyl groups and benzene rings in the molecular chain, the interaction force between PC molecular chains is strong, the entanglement is serious, and it is not easy to disentangle, which makes it difficult to produce molecular sliding under the action of external force. And deformation, the product size is stable. The performance of PC film has been further improved on the basis of raw materials, and its enviro...
