Abstract

The invention discloses an improved conductive master batch production technology. The technology comprises the following steps: preparing a main material melt, preparing a carbon black melt, and granulating master batch. The technology concretely comprises: adding 100 parts by weight of main material particles, 10-20 parts of polyformaldehyde, 5-10 parts of diatomaceous earth, 1-5 parts of disodium ethylenediamine tetraacetate, 0.1-0.5 parts of silver nano-powder, 5-10 parts of nanometer zirconium oxide, 10-20 parts of crosslinked carboxymethyl cellulose, 1-5 parts of cocamide, 0.1-0.3 parts of a polymeric flowable agent and 0.1-0.3 parts of an antioxidant, uniformly mixing above materials, adding the obtained mixture to a double screw granulator, adding the carbon black melt and the main material melt to the material melting reaction zone of the double screw granulator, and carrying out extrusion granulation through the double screw granulator. Conductive master batch in the invention has the advantages of high carbon black content, good electrical conductivity, good injection fluidity, good surface appearance quality, good toughness and good bending strength.

Description

technical field [0001] The invention relates to the technical field of conductive master batches, in particular to an improved production process of conductive master batches. Background technique [0002] Conductive masterbatch contains carbon black, the content of carbon black determines the electrical conductivity, the more carbon black content, the better the electrical conductivity, but, subsequently, the injection fluidity, surface appearance quality, toughness, bending Physical properties such as strength will be greatly reduced, so it is necessary to improve. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an improved production process of conductive masterbatch, which has high carbon black content, good electrical conductivity, good injection fluidity, surface appearance quality, Physical properties such as toughness and flexural strength. [0004] In order to achieve the above ob...
