Composition for processing porous polycarbonate material, porous polycarbonate material and preparation method thereof

Abstract

The invention discloses a composition for processing a porous polycarbonate material, the porous polycarbonate material and a preparation method thereof. The composition comprises the following components and content thereof, by weight, 65-88% of polycarbonate, 10-30% of conductive filler and 0.1-5% of auxiliaries, wherein the auxiliaries at least include antioxidant. A porous material processed by the composition is a porous polycarbonate material with permanent antistatic and conductive performance and is formed in an extrusion or injection manner by corresponding equipment such as an extruder. Compared with that of the conventional material, cost can be reduced by 20% around on the basis of keeping volume resistivity and surface resistivity constant.

Description

technical field [0001] The invention belongs to the field of macromolecules, and relates to a permanent antistatic and conductive polycarbonate porous material processing composition, a polycarbonate porous material and a preparation method thereof. Background technique [0002] Antistatic, especially conductive polymer materials are a new type of functional plastics, which are widely used in antistatic turnover boxes, fuel filters, shells and structural parts of explosion-proof products, etc. [0003] There is already a Chinese patent CN101591469A for producing conductive polycarbonate materials by adding conductive carbon black and conductive carbon nanotubes. However, because conductive carbon black and other powders are in contact with each other in the matrix to form a conductive network, a relatively large amount of addition is generally required. On the one hand, it increases Cost, on the other hand, may have an impact on the performance of the substrate. [0004] Th...

AI Technical Summary

Problems solved by technology

[0003] There is already a Chinese patent CN101591469A for producing conductive polycarbonate materials by adding conductive carbon black and conductive carbon nanotubes. However, because conductive carbon black and other powders are in contact with each other in the matrix to form a conductive network, a relatively large amount of addition is generally required. On the one hand, it increases cost, on the other hand may affect the performance of the substrate

[0004] There is already a Chinese patent CN101215413A to prepare antistatic and conductive polycarbonate materials by adding conductive carbon fibers, but carbon fibers are expensive

[0005] Chinese patent CN 101840745 A prepares antistatic and conductive polycarbonate materials by adding stainless steel fibers, but this material is not only expensive, but also has a density much higher than traditional plastics, and the advantages of light weight of plastics are greatly reduced

[0006] The methods described in the above patents can well prepare conductive polycarbonate materials, but the materials obtained in the above patents have poor mechanical properties or are expensive, and cannot be widely used in daily production and life.
