It is a kind of conventional mode.And be electromagnetically shielded both to have had any different in itself with antistatic and connect each other, how uniformly to apply to electronics
The problem of being one of crucial importance in the protective housing of product.
Utility model content
In order to solve the problem present on, the purpose of this utility model is to provide a kind of electromagnetism interference antistatic
Sheet material, can reach well deshield, on the premise of anti-static effect convenient use in various occasions.
In order to realize the above object the technical solution of the utility model is：
A kind of sheet material of electromagnetism interference antistatic, the sheet material from inside to outside include fitting TPU layer, antistatic TPU layer,
Anti- Electromagnetic heating layer, superficial layer, the antistatic TPU layer are to be compounded with the TPU plastics of antistatic agent, the anti-Electromagnetic heating layer
Combined closely with antistatic TPU layer；
There is anti-electromagnetism plated film, main part to have ferrite and metal short to be dispersed for the anti-Electromagnetic heating layer outer surface
The compound conductive plastic of fibre composition, the main part of the anti-Electromagnetic heating layer draw a wired earth.
Preferably, there is crosslinking agent between the antistatic TPU layer and anti-Electromagnetic heating layer, and the interface between two layers
Mutually it is fused into transition zone.Transition zone enhances antistatic TPU layer and anti-Electromagnetic heating layer is compatible and transition, makes its fusion tight
Close, one to carry out the two core layer combinations more firm, and two eliminate interface, make to combine together for two layers, and electrostatic is conductive and electromagnetic absorption
It can be had an effect in time in same or proximate region.
Preferably, the antistatic agent in the antistatic TPU layer is more than 60m for specific surface area2/ g carbon black, or it is short
Cut conductive fiber.The carbon black of high-specific surface area or chopped conductive fiber are as notable for the antistatic additive of antistatic TPU layer
Enhance electric conductivity and play the effect of antistatic；Wherein carbon black pellet is minimum, adsorption capacity is strong, can be internally formed reason in TPU
Conductive layer/the band thought.
Preferably, the anti-electromagnetism plated film is EMI sputter coatings.EMI sputter coatings are as a kind of efficiently anti-electromagnetism plating
The material and technique of film, using the technique of vacuum splashing and plating metal ion, vacuum sputtering EMI has high conductivity and high electromagnetic shielding
The features such as efficiency, it is widely used in electronics and communications industry.
Preferably, the material of the superficial layer is fluoroplastics, nylon or polyformaldehyde.Fluoroplastics, nylon or polyformaldehyde are equal
With splendid wearability and durability, corrosion resistance is also preferable, and superficial layer can significantly increase this practicality using these materials
The service life of novel sheet material.
The beneficial effects of the utility model are：The utility model is simple in construction, has anti-electromagnetic shielding and antistatic concurrently makees
With.TPU matter is soft and is readily modified and is bonded, by the TPU points of TPU laminating layers and TPU antistatic backings mutually to combine closely, and
The transition zone that TPU antistatic backings and anti-Electromagnetic heating layer are combined closely, transition is naturally, each layer separation integration again；TPU antistatics
Layer and anti-Electromagnetic heating layer main body are conductive plastics, and transition zone realizes the ferrite in antistatic agent and anti-Electromagnetic heating layer
With the fusion of broken-staple metal fibre, no longer with interface, can also be realized by earth lead gently beneficial to effect, electrostatic derived from electrostatic
Easily export；And after anti-electromagnetism plated film shields most of electromagnetic wave, small part electromagnetic wave is eliminated by ferrite and broken-staple metal fibre,
Realizing electromagnetism, elimination acts on by force.The utility model is simple in construction, realize antistatic and anti-electromagnetic action it is unified arrange with
Each self-reinforcing, and have and be conveniently bonded, be widely used, advantage easy to use.
