Abstract
The invention discloses a conductive master batch specially used for EPP. The conductive master batch specially used for the EPP is composed of PP with specific melt flow rate, conductive carbon black, a carbon black dispersing agent and processing aids; mixing, two-screw extruding and tabletting and dicing are carried out, so that the conductive master batch is obtained. The prepared conductive master batch is added with a foamable PP raw material, when the addition amount of the conductive master batch is 12%, the conductivity can reach 10<3> ohm.m, and no adverse effect is produced on foaming behaviour of polypropylene.
Description
Technical field
The invention belongs to macromolecular material and manufacture field thereof, especially relate to a kind of special conductive agglomerate of EPP and preparation method thereof.
Background technology
Expanded polypropylene (EPP), owing to having the performances such as the mechanics of excellence, heat insulation, fire-retardant and lightweight, is being subject to people and is paying close attention to greatly.In EPP series of products, conduction EPP has its special application extremely to pay attention to.Under normal circumstances, add conductive material in the polymer and can prepare conducting polymer.But, owing to conduction EPP exists the following aspects, and make conventional method lose efficacy.One problem is, EPP is by the PP of property, obtains through physics, chemical method foaming.If conduction PP is directly used in foaming, not only foam performance worsens, and electric conductivity also can not be guaranteed.Another problem is, owing to conductive material light weight, proportion are little, is therefore difficult to accomplish dispersed in the polymer.Conductive material adopting special manufacturing process prepare into conductive agglomerate, then is added into by conductive agglomerate in the PP master batch being suitably adapted for foam process, making EPP is practicable method.But, although conductive agglomerate kind is many at present, and is applicable to conductive agglomerate special for EPP and yet there are no patent report.
Summary of the invention
The invention aims to solve the problems referred to above, it is provided that a kind of special conductive agglomerate of EPP and preparation method thereof.
In order to realize foregoing invention purpose, the present invention adopts the following technical scheme that
