Electroconductive plastic master batch as well as preparation method and application thereof

Abstract

The invention relates to a plastic master batch, more particularly, relates to an electroconductive plastic master batch as well as a preparation method thereof and application of the electroconductive plastic master batch. The electroconductive plastic master batch is prepared from the following materials in parts by weight: 40 to 50 parts of polyester resin, 0.05 to 0.2 part of transition metal salt, 0.1 to 1 part of organic complexing agent containing amido and hydroxyl, 1 to 5 parts of foaming agent, 2 to 5 parts of surface active agent and 0.1 to 2 parts of processing agent. The electroconductive plastic master batch provided by the invention contains an organic metal complex, overlarge pressure generated on a filter subjected to plastic fusion is avoided, meanwhile, the organic metal complex does not have a color of carbon black, and the applied range of the electroconductive plastic master batch is enlarged; the electroconductive plastic master batch also contains the foaming agent, foaming is carried out in the plastic, the contact probability of the organic metal complex is improved, so that the conductivity of a plastic product is improved.

Description

technical field [0001] The invention relates to a plastic master batch, more precisely, to a conductive plastic master batch, a preparation method thereof and an application of the conductive plastic master batch. Background technique [0002] Plastic master batch (Plastic Master batch) is a concentrate made by adding a super-normal amount of plastic additives to the resin; when making plastic products, it is not necessary to add this kind of plastic additives, only need to add this kind of plastic additives in proportion A masterbatch with a super constant will suffice. Therefore, plastic masterbatch is a new type of special material for polymer material processing. There are various varieties, such as filler masterbatch, color masterbatch, flame retardant masterbatch, antistatic masterbatch, wear-resistant masterbatch, multifunctional masterbatch, etc. [0003] Usually, products made of plastic are insulators, that is, they cannot conduct electricity, but in more and mor...

AI Technical Summary

Problems solved by technology

Usually, the production cost of this kind of polymer material is high and the process is difficult, so far there is no mass production

The conductive polymer materials widely used in the prior art are generally composite polymer materials, and their fillers mainly include metal dispersions, carbon blacks, and organic complex dispersions; among them, carbon black fillers are often due to Its black color causes its application to be limited, and the conductive carbon black filler is difficult to add (generally below 35%), and is dispersed unevenly in the matrix, does not reflect the excellent electrical conductivity of conductive carbon black, and more importantly, it is difficult for the physical properties of the matrix. The performance is greatly damaged, and it is easy to pollute the production environment; after the metal dispersion is filled into the matrix, it is often difficult to pass through the filter unit in the plastic melting process, resulting in excessive pressure on the filter, which often cannot be produced normally or the production cost is too high high
