Description
Technical field
A kind of the present invention relates to technical field of coatings, more particularly to electric appliance magnetic shield 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 shell shape that sheet is low, easily realizes automatization and adapts to complexity, most with prospects.
103059672 A of CN disclose a kind of electric appliance magnetic shield coating electrically-conducting paint, and which constitutes and mass ratio is：
Acrylic resin modified 200-300 parts；Copper powder 150-200 parts；Silicon dioxide 20-30 parts；Titanate coupling agent 5-10 parts；Anti- heavy
Agent 100-120 parts.The electric appliance magnetic shield coating electrically-conducting paint also includes inorganic filler 200-300 parts.The titanium dioxide
Silicon is aerosil.Beneficial effects of the present invention are：Copper powder electrically-conducting paint has the silver-plated copper powder of double protective layers, its resistance to ring
Border property, fire resistance are greatly improved, and electric conductivity is similar to silver.
103087574 A of CN disclose a kind of electric appliance magnetic shield paint filler, the electric appliance magnetic shield coating
Filler is nucleocapsid structure, includes kernel, the first shell being coated on kernel and be coated in first shell from the inside to the outside successively
Two shells；The kernel is permeability magnetic material, and first shell is silver or copper, and second shell is polyacetylene layer.Present invention also offers the electricity
Preparation method and battery shielding coating using the electric appliance magnetic shield paint filler of the device with electromagnetic shielding paint filler.This
The electric appliance magnetic shield paint filler that invention is provided has magnetic conduction, conductive dual-use function concurrently, while outer layer is conducting polymer,
So that the electric appliance magnetic shield coating of the present invention has good dispersibility and electric appliance magnetic shield coating property.
Content of the invention
It is an object of the invention to proposing a kind of electric appliance magnetic shield coating, enable to coating and possess excellent electrical equipment
While with electromagnetic shielding coating property, but also with excellent heat dissipating.
It is that the present invention is employed the following technical solutions up to this purpose：
A kind of electric appliance magnetic shield coating, including：Polypyrrole 40-60
Firming agent 2-10
Graphene fiber 10-30,
Xi Kefu alkali vitamin A1 esters 5-15, and
Color dye 2-5；Wherein,
The graphene fiber is graphene fiber beam, and, in polypyrrole, formation is equidistantly for the fibre bundle vertical distribution
Array, the Xi Kefu alkali vitamin A1 esters microwave absorption is dispersed in the epoxy resin.
In the coating that the present invention is adopted, polypyrrole can form thin film when using, as polypyrrole possesses electromagnetic absorption spy
Property, therefore which simultaneously works as the effect of film former and electromagnetic absorption.The polypyrrole Xi Kefu alkali internal with which is dispersed in
Together, the electromagnetic interference that excessive for electric elements or other elements are produced absorbs vitamin A1 esters microwave absorption.
Absorbing material of the Xi Kefu alkali vitamin A1 esters for black, its weight only have the 1/10 of iron ball absorbing material.Xi Kefu
The suction wave frequency bandwidth of alkali vitamin A1 esters, all effective to shortwave 8mm from long wave, which is complete by electromagnetic wave energy by ion displacement mode
Portion is converted to heat energy, but the temperature of material itself is without rising.Therefore the present invention is using Xi Kefu alkali vitamin A1 esters and poly- pyrrole
Cough up, graphene fiber is combined, and prevents spilling and the interference of electromagnetic wave well, while heat can be conducted, increase electrical equipment
Heat dispersion.
The graphene fiber of the present invention is chopped fiber, and which not only possesses rigidity, while there is 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 electric appliance magnetic
Shielding coating excellent effect.
Electric appliance magnetic shield coating of the present invention, which can be applicable to the surface of the electrical equipment such as household electrical appliance, computer,
Change color and luster is played, is increased thermal diffusivity and is realized electric appliance magnetic shield coating function.
