Family's railway traffic quickly grows, and the control of the railway system becomes increasingly complex, and electrical control equipment gets more and more, to cabling requirements amount
The most increasing.Wherein antistatic behaviour seems and is even more important.
In " preparation of conduction _ anti-electrostatic polymer nano composite material and performance study thereof " literary composition, author utilizes low melting point
The conductive filler such as metal, CNT prepares conductive anti-static polymer composites and fiber, it is proposed that new preparation
Method and new principle, the low-melting-point metal use electrical conductivity height, easily processing is as conductive filler, by melt blending and solid phase
The methods such as stretching, prepare composite fibre, show that polymer/low melting point conducting metal composite fibre has resistivity along with stretching
The raising of multiplying power and the character that reduces, compare with the composite fibre not containing low conduction melting-point fibers, the intensity of its composite fibre
All increase with elongation at break.Metal is significantly reduced by interpolation CNT and nano imvite in composite fibre
Grain diameter so that composite fibre obtains more excellent electrical property and mechanical property.Although the present invention can solve the problem that cable
The requirement of the aspects such as conductive anti-static, but it is as the development of locomotive technology, laying environment and the serviceability requirement to cable
More and more higher, simple single performance can not meet the market demand, and the present invention improves on the basis of this, to reaching resistance to
Good bending property, fire protection flame retarding, environmental protection, ageing-resistant etc. characteristic so that it is reach in railway engineering the use to cable and want
Ask.
