Description
Technical field
A kind of the present invention relates to plastics arts, more particularly to preparation method of composite conductive plastic.
Background technology
Plastics typically all have good insulating properties, and are therefore widely applied in a lot of fields, such as electric wire
Cable, electric etc..But the progress of development and science and technology with society, becomes on the contrary in the insulating properties of some field plastics
Into unfavorable factor, how then people improves the electric conductivity of plastics if beginning one's study.Mainly there are two methods, Yi Zhongshi at present
Molecular structure, i.e. preparation structure type conductive plasticss are improved, another kind is compound with conductive filler, that is, prepare compound-type conducting
Plastics.
With social constantly progressive, electronics, the continuous development of electrical equipment manufacturing technology, the application of conductive plasticss is increasingly
Many, demand is increasing, and the also more and more higher of the requirement to conductive plasticss, composite conductive plastic be presently mainly to
High performance, multifunction, good processability and low cost aspect development, wherein crucial technology include：(1) how
On the premise of excellent electric conductivity and shielding propertiess are kept, reduce the consumption of conductive filler as much as possible, to reach raising
Processing characteristics, the purpose for reducing production cost；(2) how the electric conductivity of compound conductive plastic is improved as far as possible, and
Keep good processing characteristics and mechanical property；(3) how conductive plasticss are made while possessing conductive plasticss, it may have outstanding
Other performances such as fire-retardant, heat-resisting, wear-resisting, corrosion-resistant, high heat conduction；(4) new high-effective conductive filler and new conductive plasticss system
The exploitation of standby technique.
The technique of production fiber composite type conductive plasticss is mainly twin screw reaction extrusion process at present, and fiber is in the technique
During be subject to very strong shear action, cause fibre length too short, addition is high, and fiber is serious to equipment attrition.State
Outer had enterprise to produce conductive plasticss using cable cladding process, and the technique can keep the draw ratio of fiber to greatest extent, make
Standby conductive plasticss properties are excellent, but the country does not still break through.
Content of the invention
It is an object of the invention to a kind of preparation method of composite conductive plastic is proposed,.
It is that the present invention is employed the following technical solutions up to this purpose：
A kind of preparation method of composite conductive plastic, including：The conductive plasticss are by 30～60% acrylic nitrile-butadienes two
Alkene-styrene, 20～35% Merlon and 20～35% stainless steel fibres composition, its preparation technology technique include：By 30～
60% acrylonitrile-butadiene-styrene (ABS), 20～35% Merlon and 20～35% stainless steel fibres are melted altogether on a mill
Mixed, melt temperature is 320～350 DEG C, after mix homogeneously, extrusion, and cooling pelletization.
The present invention has broken the external technical monopoly to China, is successfully prepared stainless steel fibre/polycarbonate/acrylonitrile
Fine-butadiene-styrene (SSF/PC/ABS) composite conductive plastic, its specific insulation is minimum to can reach 10-2Ω cm, draw
Stretch intensity and reach as high as 247MPa, bending strength can arrive 299MPa, and shield effectiveness can reach 70～90dB, disclosure satisfy that aviation is navigated
It and military requirements.
