Abstract
The invention discloses a kind of special conductive agglomerates of EPP, it is made of the PP of specific melt flow rate (MFR), conductive carbon black, carbon black dispersant and processing aid, and conductive agglomerate is obtained by mixing, twin-screw extrusion tabletting and pelletizing.Conductive agglomerate prepared by the present invention, is added into expandable PP raw materials, and when conductive agglomerate additive amount is 12%, conductivity can reach 103Ω m, meanwhile, any adverse effect is not caused to polyacrylic foaming behavior.
Description
Technical field
The invention belongs to high molecular material and its manufacture fields, more particularly, to a kind of special conductive agglomerates of EPP and its system
Preparation Method.
Background technology
Expanded polypropylene (EPP) is due to performances such as excellent mechanics, heat-insulated, fire-retardant and lightweights, by people
Greatly concern.In EPP series of products, application that conductive EPP has its special and by attention.Under normal conditions, it is polymerizeing
Conductive material is added in object can prepare conducting polymer.But due to conductive EPP is there are the following aspects, and
Conventional method is set to fail.One problem is that EPP is the PP by property, is obtained by physics, chemical method foaming.Such as
Conductive PP is directly used in foaming by fruit, and not only foam performance deteriorates, but also electric conductivity also cannot be guaranteed.Another problem
It is, since conductive material is light, proportion is small, it is difficult to accomplish evenly dispersed in the polymer.By conductive material using special
Manufacturing process is prepared into conductive agglomerate, then conductive agglomerate is added in the PP master batches for being suitably adapted for foam process, and EPP, which is made, is
Practicable method.But although conductive agglomerate kind is many at present, and yet there are no suitable for the dedicated conductive agglomerates of EPP
