Description
Technical field
The utility model relates to a kind of wave absorption base material, particularly a kind of nonflammable cube-corner elements body wave absorption base material.
Background technology
Before the present utility model, the existing wave absorption base material that uses is made with sponge.Because it is flammable that sponge inhales the ripple carrier, and several kilowatts/square metres of microwave powers irradiations will be born in the HIGH-POWERED MICROWAVES darkroom, and just very easily burning is therefore dangerous, and just need to install expensive fire-fighting fire-proof facility for safety; The sponge absorbing material in use, dust is big, and is unholiness, toxic gas volatilization is easily aging.
Summary of the invention
The purpose of this utility model just is to provide a kind of novel nonflammable cube-corner elements body wave absorption base material, to overcome big, the easy defective such as aging, toxic gas volatilization of existing flammable, the dust of prior art sponge absorbing material.
The technical solution of the utility model is:
Nonflammable cube-corner elements body wave absorption base material, its major technique is characterised in that at the carrier nonwoven fabrics and simultaneously applies one deck compo, compo is the material that is mixed by aluminum-magnesium compositing powder, water-soluble plasticizer, cementing agent, carbon black and water, be made into cube-corner elements body wave absorption base material, the compo layer outside.
The further technical scheme of the utility model is:
Its further technical characterictic is in cube-corner elements body bottom another cube-corner elements body to be set, and its pyramid subtended angle α is greater than its outer cube-corner elements body pyramid subtended angle α.
Advantage of the present utility model and effect are difficult combustion, need not increase expensive fire prevention fire fighting device, avirulence and volatilization, and clean no dust, hygienic environment-protecting, stable performance, long service life is the first-selection of green microwave dark room.
Description of drawings
Fig. 1-the utility model structural sheet figure.
Fig. 2-the utility model appearance assumption diagram
Fig. 3-cube-corner elements body is provided with the structural drawing of pyramid subtended angle greater than the outside in the bottom.
The structural drawing that Fig. 4-a plurality of cube-corner elements bodies link together and use.
Embodiment
As shown in Figure 1, carrier is a nonwoven fabrics 1, at its outside coating one deck dope layer 2, the coating that dope layer 2 is in harmonious proportion by aluminum-magnesium compositing powder (also can use magnesia powder), water-soluble plasticizer, cementing agent, carbon black and water, strengthen the structural behaviour of nonwoven fabrics 1, difficult combustion, collapsible; Use mechanical impression then, fold, make, be bonded to the cube-corner elements body, its bottom is a long or foursquare structure, its height h
1Be the decay section, the pyramid height is H
1, deduct a decay section H to cube-corner elements body top from the bottom
1-h
1Be matching section, the pyramid bottom width is b, and the pyramid subtended angle is α, as shown in Figure 2.
In cube-corner elements body bottom, other little cube-corner elements body 3 is set, adopt in this example four onesize, but therefore its pyramid subtended angle α closes up near the cube-corner elements body bottom externally, as shown in Figure 3 greater than the pyramid subtended angle of the cube-corner elements body of outside.Can stop the electromagnetic wave of outside cube-corner elements body top reflected back, shield effectiveness is better.
Shown in Figure 4, be that a plurality of cube-corner elements bodies are combined, be convenient to transportation, install and use.
In concrete the use, choosing α is 6～8 degree, and pyramid bottom width b is 80.5mm, pyramid H
1Be 680-700, decay section h
1Be 80-100mm, matching section H
1-h
1Be 500-700mm, then in 800MHz～40GHz frequency range, have good wave-sucking performance, reflectivity is low.
Choosing α is 7～9 degree, and pyramid bottom width b is 163mm, pyramid H
1Be 1500-1650mm, decay section h
1Be 500-650mm, matching section H
1-h
1Be 950-1150mm, then in 30MHz～40GHz frequency range, have good wave-sucking performance, EMC difficulty that reflectivity is low burns and sucks wave material.
Choosing α is 10～12 degree, and pyramid bottom width b is 123mm, pyramid H
1Be 700mm, decay section h
1Be 120mm, matching section H
1-h
1Be 580mm, inhale with ferrite in 30MHz～40GHz frequency range then that ripple plate coupling has good wave-sucking performance, reflectivity is low.
Choosing α is 12～14 degree, and pyramid bottom width b is 60mm, H
1-h
1Be 220-250mm, top 50-80mm length section only is coated with the carbon black absorbing coating, then has good wave-sucking performance in 10GHz～150GHz frequency range, reflectivity is low, has solved the contradiction between matching properties and the attenuation characteristic preferably.
Only be coated with carbon black at cube-corner elements body top 50-80mm and inhale the ripple layer, reduce to inhale ripple cell cube pyramid head relative dielectric constant, further improve the matching properties of absorbing material.
The scope that the utility model is asked for protection not only is confined to the description of above-mentioned embodiment.
