As a kind of conventional insulating materials in electronics, electrical equipment and electrotechnical apparatus, mica paper has electrical strength height,
Dielectric loss is low, and sheet resistance and volume resistance are high a little, while are also equipped with excellent heat resistance, water resistance, chemically stable
Property and physical strength, and relative to other traditional dressings have antiacid, alkali resistant, resistance to compression and it is resistance to stripping point property.But mica is in itself
Shielding properties, insulating properties, tensile strength and stability room for promotion it is little, cause existing mono-material mica paper on the market
It is difficult to meet higher and higher electronic equipment performance requirement.
Utility model content
The technical problem that the utility model solves is to provide a kind of shield type graphene mica paper, to solve the above-mentioned back of the body
The shortcomings that in scape technology.
The technical problem that the utility model solves is realized using following technical scheme：
A kind of shield type graphene mica paper, including mica paper base material, cross is provided with the face of the mica paper base material
Dot matrix hole, meanwhile, a layer graphene is formed on a side surface of the mica paper base material, and in the mica paper base material
One layer of heat-conducting glue layer is then formed on another side surface, one layer of carbon-fiber film for being provided with honeycomb hole is formed in this heat-conducting glue layer
Layer, meanwhile, one layer of reinforcement mica paper is also formed in the outer surface of this carbon fiber film layer.
In the utility model, the mica paper base material is one layer of phlogopite paper, and the thickness of this mica paper base material is 0.3
~0.5mm.
In the utility model, the reinforcement mica paper is one layer of phlogopite paper or muscovite paper, and this reinforcement mica
The thickness of paper is 0.2~0.3mm.

~30mm, and the spacing between the central point in adjacent cross dot matrix hole is 50mm, to obtain optimal radiating effect simultaneously
And physical property.
In the utility model, the heat-conducting glue layer is epoxide-resin glue, organosilicon heat-conducting glue, polyurethane adhesive or thermal conductive silicon
A kind of shaping in glue, its thickness is 0.2~0.3mm, and the thickness for the carbon fiber film layer being molded in it is heat-conducting glue thickness
The 1/2~2/3 of degree.
In the utility model, the graphene is monatomic or diatomic graphene.
Beneficial effect：The utility model can effectively increase cloud while mica paper physically and electrically performance in itself is kept
The overall capability of electromagnetic shielding of female paper, effectively avoid it is adjacent put interfering between electronic product, meanwhile, relative to traditional list
Layer mica paper possesses thinner thickness and more preferably peeling force, suitability for secondary processing and structural stability, it is easier to small, micro-
It is molded on type component.
