Abstract
The invention relates to a difficult-to-burn type wave-absorbing material for an electromagnetic compatible anechoic chamber and a preparation method thereof. The difficult-to-burn type wave-absorbing material comprises a unit body of a base body pyramid framework, wherein the outer surface of the pyramid framework is pasted with a difficult-to-burn type slice wave-absorbing material layer. The difficult-to-burn type wave-absorbing material can be obtained through the steps of plate cutting, framework assembling, slice cutting, pasting forming and appearance decorating. Compared with the prior art, a glass magnesium board is adopted, the flame-retardant level of the difficult-to-burn type wave-absorbing material can be increased, the fireproof performance during the using of the electromagnetic compatible anechoic chamber is increased, and thus the input of fireproof facilities in the electromagnetic compatible anechoic chamber is reduced. Since a surface mount technology is adopted, the painting non-uniform performance caused as a conductive wave-absorbing body is directly painted on a base material originally is improved, and the difficult-to-burn type wave-absorbing material for the electromagnetic compatible anechoic chamber and the preparation method, disclosed by the invention, have the advantages that the uniformity of the absorbing performance of the difficult-to-burn type wave-absorbing material is good, and the like.
Description
Technical field
The present invention relates to a kind of novel wave-absorbing material and preparation method thereof, relate generally to a kind of absorbing material that is applied to the special use of electromagnetic compatibility laboratory.
Background technology
The absorbing material of one of chief component in electromagnetic compatibility laboratory equipment, traditional absorbing material generally adopts the absorbing material of combined type, adopt ferrite wave-absorbing material and pyramid absorbing material, adopt the technique of pasting or mounting to be arranged on side and the end face in laboratory.
When tradition ferrite wave-absorbing material is installed complexity, quantities Datong District, price is higher, the present invention can replace traditional combined type absorbing material, make no longer needs ferrite wave-absorbing material when building electromagnetic compatibility laboratory, directly lays absorbing material of the present invention.Greatly reduce the cost in laboratory, reduce the difficulty of construction and installation and shorten the cycle that build in darkroom.
The fire resistance of previous Chinese patent application 200910030899.0 is 26%, and of the present invention be nonflammable, oxygen index can reach 80%, reduces darkroom fire risk in use.
Summary of the invention
The object of this invention is to provide a kind of electromagnetic compatibility use for laboratory absorbing material, for building electromagnetic compatibility laboratory, meet the requirement of various electromagnetic compatibility tests to experimental situation.
The technical solution used in the present invention is: a kind of electromagnetic compatibility use for laboratory absorbing material, comprise the cell cube of matrix pyramid skeleton, and pyramid skeleton outside surface is pasted nonflammable thin slice absorbing material layer.
On nonflammable thin slice absorbing material layer, can also there is outside surface decorative layer.
Said centrum skeleton (pyramid skeleton) wherein, refers to that a tapered skeleton that bonds together with multi-purpose adhesive after adopting glass magnesium plate according to certain size cutting and form is for supporting nonflammable thin slice absorbing material.
Wherein said glass magnesium plate (being commonly called as magnesium oxide plate can buy in market) is with magnesium oxide, magnesium chloride, and water ternary system, be configured and add modifier and make, the magnesium gelatinous material of stable performance, take neutral and alkali glass fiber net as reinforcing material, the novel noncombustibility ornament materials that the light material of take is composited as filling material.
Said nonflammable thin slice absorbing material wherein, preferably adhesive-bonded fabric is base material through fire-retardant and inhale the nonflammable thin slice that ripple processes and inhale material, and its thickness range is 0.2mm-0.5mm, and surperficial resistance per square is 300-500 ohm;
Wherein said outside surface is decorated, and refers to decorative paint or decorates wallpaper effects on surface and beautify.
Multi-purpose adhesive, the preferably good board multi-purpose adhesive of brothers or white glue with vinyl.
Another object of the present invention is to provide the preparation method of said electromagnetic compatibility use for laboratory absorbing material, comprises the following steps:
1) sheet material cutting: glass magnesium plate is carried out to excision forming with High Rotation Speed cutting equipment;
2) skeleton assembling: the joint face of the sheet material cutting is gone up to multi-purpose adhesive on the way, and be assembled into taper type skeleton;
3) thin slice cutting: nonflammable thin slice absorbing material is placed on and carries out impact briquetting in flat-press indentation machine;
4) stickup shaping: in step 2) assemble the outside surface of skeleton and inside surface that step 3) cuts thin slice and go up glue on the way, and bonding assembled formation.
5) decorative appearance: by the good absorbing material of step 4) stickup shaping, by the method for spraying, decorative paint is sprayed
At outside surface or play the effect of decoration by the method for pasting facing paper.
The present invention compared with prior art, has adopted glass magnesium plate, can improve the fire-retardant rank of absorbing material, improves fire protecting performance in the use of darkroom, therefore reduces the input of fireproofing installation in darkroom.Owing to having adopted the technology of surperficial stickup, improved and originally directly on base material, brushed the brushing inequality of leading wave-absorber and causing, there is the plurality of advantages such as material absorptive character high conformity.
