Abstract
The utility model discloses an electromagnetic compatible casing adopting a metal-coated glass fiber composite mat. The electromagnetic compatible casing comprises a glass fiber yarn, a metal-coated glass fiber reflection layer and a metal-coated glass fiber composite mat attenuation layer containing a microwave absorption material which are sequentially arranged from inside out. According to the composite layer structure adopted by the utility model, the effects that the casing structure is enhanced and the electromagnetic shield is effectively ensured can be achieved.
Description
Technical field
The utility model relates to a kind of electromagnetic screen, particularly a kind of plating glass composite felt electromagnetic compatibility shell.
Background technology
Electromagnetic technique is a double-edged sword, and the utilization of electromagnetic technique brings easily simultaneously to people, and extensive utilization high-power, highly integrated electric utility has but caused such as electromagnetic interference, electromagnetism divulges a secret and a series of safety and environmental problem such as electromagnetic pollution.Along with the increase of electromagnetic wave radiant intensity and the diversity of electrical equipment, traditional shielding material and shielding mode can not satisfy the comparation and assessment requirement under the complex electromagnetic environment.
Though because traditional reflective shielding material can reach higher shield effectiveness, this type material is to utilize good electric conductivity that electromagnetic wave is carried out reflex then, with energy constraint in the specific region, not with effective energy transformation.Will certainly increase other regional field intensity the colleague who weakens a regional field intensity like this, when serious even cause resonance, influence utilization.
The utility model content
The utility model technical problem to be solved provides a kind of plating glass composite felt electromagnetic compatibility shell.
For solving the problems of the technologies described above; The utility model is realized as follows: a kind of plating glass composite felt electromagnetic compatibility shell, the metallized glass fiber composite felt damping layer that comprises glass fiber yarn, the metallized glass fiber reflecting layer that sets gradually from inside to outside and contain microwave absorbing material.
The good effect of the utility model is: the lamination layer structure that the utility model adopted, can play enhancing to shell structure, and guaranteed the effect of electromagnetic shielding again effectively.
Description of drawings
Fig. 1 is the structural representation of the plating glass composite felt electromagnetic compatibility shell that embodiment provided of the utility model;
Wherein, 1 glass fiber yarn, 2 metallized glass fiber reflecting layer, 3 metallized glass fiber composite felt damping layers
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
As shown in Figure 1; One of the utility model plating glass composite felt electromagnetic compatibility shell that embodiment provided; Adopt the composite laminated structure to carry out the preparation of housing, comprise S glass fiber yarn 1, metallized glass fiber reflecting layer 2 that sets gradually from inside to outside and the metallized glass fiber composite felt damping layer 3 that contains microwave absorbing material.
One, the S glass fiber yarn 1: be called the high-strength glass fibre yarn again; S glass fiber yarn filament strength is 4004200MPa; Elastic modelling quantity is 85-90GPa; Filament strength than E glass fibre has improved 30%-40% respectively, elastic modelling quantity has improved 16%-20%, and behind the making composite, whole mechanical property is higher than the E glass fiber compound material more than 30%.Therefore, internal layer adopts the S glass fiber yarn, can effectively guarantee the requirement of mechanical properties such as intensity that material is required and anti-impact force.
Two, metallized glass fiber reflecting layer 2: adopt ultra-fine continuous conduction aluminium-coated glass-fibre roving to twine and form the reflection of electromagnetic wave layer.Utilize its excellent conducting performance, can major part be penetrated the reflection of electromagnetic wave echo attenuation layer of outside damping layer on the one hand, increase absorption loss, improve shield effectiveness; On the other hand, in conduction aluminium-coated glass-fibre roving, add a certain proportion of glass fiber precursor, can improve intensity, make it in the effect of performance reflection electromagnetic wave, also play to a certain extent the enhancing of shell structure is rented.
Three, metallized glass fiber composite felt damping layer 3: the metallized glass fiber composite felt that contains the microblogging absorbing material; The three-dimensional structure that this layer material is made up of metallized glass fiber, chemical fibre; Distributing in the space of three-dimensional structure ferrite, plating micro mist electromagnetic wave absorbent material are the primary structure layers of electromagnetic radiation shielding.It mainly is through the mode that the reflection of electromagnetic wave of material and air interface, electromagnetic wave get into the multipath reflection of material internal between three-dimensional structure, scattering at the absorption loss of the eddy current of internal transmission formula, inductor loss, electromagnetic wave absorbent material and the electromagnetic wave incidence wave of decaying, and reaches the effect of electromagnetic shielding.
The lamination layer structure that the utility model adopted can play the enhancing to shell structure, has guaranteed the effect of electromagnetic shielding again effectively.Anti-electromagnetic-radiation shield effectiveness: >=60dB, breakdown strength＞30KN.
