Description
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of electromagnetic screen coating.
Background technology
With developing rapidly for electronic industry and telecommunications, electronics and electrical equipment are widely used.Existing
Electrical equipment, all has various electric elements.These electric elements can produce electromagnetic radiation.Shell due to electronic equipment
Body material is usually plastics, and therefore electromagnetic wave can be passed freely through, so as to cause electromagnetic pollution.Electromagnetism spoke for attenuation apparatus
Penetrate and electromagnetic interference each other, need to metallize plastic casing or conducting.Wherein, electrically-conducting paint has into
The advantages of this low, easy realization is automated and adapts to the shell shape of complexity, most with prospects.
103059672 A of CN discloses a kind of electromagnetic-shielding conductive coating, and its composition and mass ratio are：Modified acroleic acid
Resin 200-300 part；Copper powder 150-200 part；Silica 20-30 part；Titanate coupling agent 5-10 part；The anti-agent 100-120 that sinks
Part.The electromagnetic-shielding conductive coating also includes inorganic filler 200-300 part.The silica is aerosil.This
The beneficial effect of the invention is：Copper powder electrically-conducting paint has the silver-plated copper powder of double protective layers, and which is environment resistant, and fire resistance is carried significantly
Height, electric conductivity are similar to silver.
103087574 A of CN discloses a kind of electromagnetic shielding filler, and the electromagnetic shielding filler is core shell structure, from interior
To including kernel, the first shell being coated on kernel and the second shell being coated in first shell successively outward；The kernel is magnetic conduction
Material, first shell are silver or copper, and second shell is polyacetylene layer.Present invention also offers the preparation method of the electromagnetic shielding filler
With the battery shielding coating using the electromagnetic shielding filler.The electromagnetic shielding filler that the present invention is provided has magnetic conduction, conductive double concurrently
Weight function, while outer layer is conducting polymer so that the electromagnetic screen coating of the present invention has good dispersiveness and electromagnetic screen
Cover performance.
Content of the invention
It is an object of the invention to a kind of electromagnetic screen coating is proposed, enable to coating and possess excellent electromagnetic wave shielding
While energy, but also with excellent heat dissipating.
For reaching this purpose, the present invention is employed the following technical solutions：
A kind of electromagnetic screen coating, including：Polypyrrole 40-60
Curing agent 2-10
Graphene fiber 10-30,
Fe3O4Microwave absorption 5-15, and
Color dye 2-5；Wherein,
The graphene fiber is graphene fiber bundle, and the fibre bundle vertical distribution is formed equidistantly in polypyrrole
Array, the Fe3O4Microwave absorption is dispersed in the epoxy resin.
In the coating that the present invention is adopted, polypyrrole can form film when using, as polypyrrole possesses electromagnetic absorption spy
Property, therefore which simultaneously works as the effect of film forming agent and electromagnetic absorption.The polypyrrole Fe internal with which is dispersed in3O4Microwave is inhaled
Receive together, the electromagnetic interference that excessive for electric elements or other elements are produced absorbs.
The graphene fiber of the present invention is chopped fiber, and which not only possesses rigidity, while with perfect two dimensional crystal structure,
Its lattice is the hexagon surrounded by six carbon atom, and thickness is an atomic layer.Bonded by σ between carbon atom, in conjunction with
Mode is sp2 hydridization, and these σ keys impart the extremely excellent mechanical property of Graphene and structural rigidity.The hardness ratio of Graphene
Best iron and steel is strong 100 times, or even will also exceed diamond.In Graphene, each carbon atom has the p electricity of a non-bonding
Son, these p electronics can be moved freely in crystal, and movement velocity is up to the 1/300 of the light velocity, imparts Graphene good
Electric conductivity.Graphene is the transparent conductive material of a new generation.
Therefore the graphene conductive material using the present invention is together with film of poly pyrrole so that the coating electromagnetic shielding effect
Really excellent.
Electromagnetic screen coating of the present invention, its can be applicable to the surface of the electrical equipment such as household electrical appliance, computer, play and change
Become color and luster, increase thermal diffusivity and realize electro-magnetic screen function.
