Abstract

The invention discloses a kind of corrugated cases of anti electromagnetic wave interference, the corrugated case is followed successively by outer layer facial tissue, corrugating media and internal layer facial tissue from outside to inside, and it is contacted with each other position adhesion by adhesive in each layer, the outer layer facial tissue is the facial tissue of Copper-Aluminum compound, the corrugating media is the modified corrugating media of carbon black filled/graphene, the corrugating media is in quadrangle or ellipse setting, the internal layer facial tissue is the carbon fiber paper composite layer of nanometer ferroferric oxide modification, and the adhesive is metal-based compound adhesive.Corrugated case of the invention is by selecting reasonable formula materials and Structure Combination Design, make the Electromagnetic Interference field of varying strength in corrugated case in by reflection, absorb and balance out, to make corrugated case when keeping itself intrinsic excellent properties, also have the effect of being electromagnetically shielded.

Description

A kind of corrugated case of anti electromagnetic wave interference
Technical field
The present invention relates to corrugated case technical fields, relate in particular to a kind of corrugated case of anti electromagnetic wave interference.
Background technique
Corrugated board is the adherend of a multilayer, it is at least made of one layer of waveform core layer and a layer paperboard.Corrugation Cardboard has very high mechanical strength, can be to being fallen by the collision in cargo handling process and falling, while being made using corrugated board Packing container play a role to the mark of commodity, beautification and publicity.
The existing corrugated case used, at low cost, light weight, easy processing, printing adaptability is excellent, stores and carries The advantages that conveniently and convenient for recycling, therefore be widely used.Functional requirement with the development of state-of-the-art technology, to carton Day increase, such as to the packaging of accurate semiconductor electronic component, transport with regard to needing to use the paper with electro-magnetic screen function Case, and existing carton is to product the effects of only serving anticollision, moisture-proof, waterproof or antibacterial, if these products are passing through Electromagenetic wave radiation is just had to the product when overscanning and safety check, is limited by the influence of common carton material, is not had at all The effect of electromagnetic shielding, these electromagenetic wave radiations will bring fine and close injury to sophisticated semiconductor electronic component, to make precision Semiconductor electronic component, which is not available, to be scrapped, and causes huge economic loss to company.
Even if the carton with electro-magnetic screen function sporadicly occurred on existing market, since its structure is single or material Unreasonable with Structure Combination Design, when the effect by high-intensity magnetic field or electric field of electronic component in carton, often it is played Shield effectiveness it is extremely limited.
Therefore, it needs to design a corrugated case that can effectively shield with different electromagnetic intensities.
Summary of the invention
