Abstract
The invention discloses a conductive plastic material which comprises (by weight ratio) the following materials (by weight percent): carbon black, conductive substance consisting of metal dust and conductive high polymers 10-50%, plastic resin 40-70%, filler 5-10% and auxiliary agent 5-10%. The invention also discloses the process for preparing the material.
Description
Technical field
The present invention relates to a kind of conductive plastic material, its preparation method and the application in conductive shield occasion keyboard button, hollow battery cell case and antistatic material that wrapping material, anti-electromagnetic interference material, electronic apparatus are used.
Background technology
Plastic material all was an isolator in the past.Have the macromolecular material of electroconductibility by in plastic material, adding some at present, make plastic material have conductivity, can replace metallic substance to use, have more superior performance, become a kind of trend.But because conducting polymer infusibility indissoluble, can't machine-shaping, use is restricted, and produce conductive plastic material at present because conductivity is bad, the perhaps kind rareness of conductive filler material, the dispersing property of this material is bad simultaneously, and the material surface of working it out is a bit or various flake, disadvantages such as the bad tie rod pelletizing of the material of working it out, thus make this trend obtain containment to a certain extent.
Summary of the invention
First purpose of the present invention will provide a kind of conductive plastic material exactly, and this conductive plastic material has excellent conducting performance.
Second purpose of the present invention is the preparation method that a kind of above-mentioned conductive plastic material will be provided.
The 3rd purpose of the present invention is above-mentioned conductive plastic material will be applied in conductive shield occasion keyboard button, hollow battery cell case and the antistatic material that wrapping material, anti-electromagnetic interference material and electronic apparatus use.
The technical solution adopted for the present invention to solve the technical problems is:
Conductive plastic material, it is characterized in that it includes the material of following weight percent: by the molecular conducting material 10%～50% of conductive carbon black, metal-powder and conductive polymer, plastic resin 40%～70%, filler 5%～10% and auxiliary agent 5%～10%, wherein metal-powder is one or more the mixture in iron powder, aluminium powder or the copper powder, conducting polymer is polyacetylene or Polythiophene, and plastic resin is that PE resin and the rubber by linearity is made.
Above-mentioned auxiliary agent is for having maleic anhydride or acrylic acid polymer bulking agents, titanate coupling agent and oxidation inhibitor.
Above-mentioned oxidation inhibitor is the oxidation inhibitor of amine or phenols.
Above-mentioned filler can adopt lime carbonate, talcum powder or calcium sulfate.
Conductive plastic material of the present invention can prepare by the following method:
(1). plastic resin is joined in the high mixer, add the molecular conducting material of conductive carbon black, metal-powder and conductive polymer and mix, add auxiliary agent then, add filler at last, mix the back blowing;
(2). with prepared mixture, be poured in the twin screw extruder, control segmentation temperature is 120-160 ℃, 130-170 ℃, 140-180 ℃, 150-190 ℃, 170-200 ℃, extrudes the back by the tank tie rod;
(3). tie rod after overcooling, is cut into particle by dicing machine;
(4). at last particle is extracted in the dryer oven dry and obtains required finished product.
Because conductive plastic material of the present invention has excellent conducting performance, so it has broad application prospects in the fields such as conductive shield occasion keyboard button, hollow battery cell case and antistatic material that wrapping material, anti-electromagnetic interference material and electronic apparatus are used.
The invention has the beneficial effects as follows: the present invention is by adding in plastic material by carbon black, metal-powder and conducting polymer composite, add a certain amount of filler simultaneously, thereby make the plastic material that does not possess conductivity have excellent conducting performance and mechanical property, to realize the purpose of functionalization, it can replace metallic substance to use, and has more superior performance; This conductive plastic material is thermoplastic plastic material, has the performance that processing is repeatedly used, and environmental protection is free from environmental pollution, has the reusable function of recovery; Conductivity is good, and electroconductibility is lasting; Preparation method of the present invention extrudes by twin screw and makes its modification, the conductive plastic material that utilize completion method to access to be uniformly dispersed, consistency is good.
