Another big public hazards after dye and noise pollution, electromagnetic wave radiation biological tissue, electromagenetic wave radiation lead to human lesion, electricity
Electromagnetic wave radiation influences offspring, it should take effective protection measure, avoid and reduce influence of the electromagnetic radiation to human health.Together
When, with the electronic apparatus device quantity on automobile drastically increase and the improvement of people's living standards and environmental consciousness
Enhancing has a very important significance the reduction that electromagnetic radiation is carried out in automobile.
Existing electromagnetic screen coating based on conductive coating, the electroconductive stuffing that is added in conductive coating be usually gold,
The non-metal powders such as the metal powders such as silver, copper, nickel and carbon black, graphite.The electric conductivity highest of bronze, chemical stability is good, but valency
Lattice are expensive, so that using being restricted.The electric conductivity of silver powder is also very excellent, and price is low compared with bronze, although with easily being precipitated after glue,
There is " migration " phenomenon.Copper, the performance of nickel and silver are close, and price is more much lower but oxidizable than silver, and electric conductivity is unstable, with glue
Durability is poor.Carbon black, powdered graphite are as conductive filler, and good dispersion is cheap, but electric conductivity is poor.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can eliminate electromagnetic screen
Cover conductive plastics paint of effectiveness of the environment resistant problem of metal powder in coating and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：A kind of conductive plastics paint of effectiveness,
It is characterized in that, the plastic paint includes the component of following parts by weight：
The acrylic resin is a kind of high hydroxyl value acrylic resin, containing a certain amount of benzene ring structure, is not only provided
Conductance, also gives paint film certain hardness, such as may be selected from commercially available Hypomer FS-3359 or Hypomer FS-4761.
The polyester resin is a kind of unsaturated polyester (UP), and main chain is shorter in monomer and contains double bond, contains benzene in branch
Ring structure.It such as may be selected from commercially available Hypomer PE-8043 or Nuplex Setalux2588.

It first mixes slowly, then with the rotating speed high-speed stirred 30min of 2000~2500rpm, the conductive plastics of effectiveness is made
Paint.
For acrylic resin using the acrylic resin of high hydroxyl as main base, itself has certain conduction in the present invention
Property；The polyester used is unsaturated polyester (UP), and contained unsaturated bond also has certain electric conductivity, further increases oil
The electric conductivity of paint；Select Nano grade carbon, have good electric conductivity, be paint in main conducting medium, electric conductivity
Can be close with metal, it is a kind of good conductor；Used wetting dispersing agent can be good compatible with resin, and carbon black is divided
Scattered property is also very good and will not reduce the electric conductivity of carbon black.
Compared with prior art, the present invention has following excellent by special resin collocation and the special selection of pigment, auxiliary agent
Point：
(1) good electric conductivity.The electric conductivity of normal conditions paint film is better, and shielding electromagnetic waves effect is got over
It is good, it says that the base-material of use and pigment have good electric conductivity in the present invention, makes paint film that there is preferable electric conductivity, so as to
With good effectiveness.
(2) it is environment resistant good.By the use of the good nano-sized carbon of electric conductivity as main conductive medium, making for metal powder is given up
With fundamentally solving the problems, such as caused by metal powder easily precipitation, oxidizable.
(3) price is low.Due to using conducting medium be carbon material, derive from a wealth of sources, it is renewable, not to gold and silver etc.
Metal is rare and non-renewable like that, and with the development of nanometer technology, the preparation process of nano-carbon material will more optimize,
Price also can be more cheap.
