Description
Technical field
The utility model belongs to ceramic technical field, and in particular to integrally equal arcs silicon nitride is anti-for a kind of MULTILAYER COMPOSITE
Play ceramic wafer.
Background technique
Silicon nitride bulletproof ceramic plate is to be widely used in the military dress such as individual combat flak jackets and tank, panzer, blindage
Standby critical component, improves the protective capacities of equipment.Country's bulletproof ceramic plate matter is broadly divided at present: silicon carbide and boron carbide are anti-
Play ceramic wafer, quartz-ceramics silicon nitride bulletproof ceramic plate, aluminium oxide ceramics silicon nitride bulletproof ceramic plate etc..Ceramic wafer generally requires
It is compound with organic material progress, bulletproof effect can be just played, whole bulletproof ceramic plate is manufactured both at home and abroad and mainly uses whole big plate
It is compound with organic polymer.
Disclosed in patent CN102183177B a kind of integral curved large scale aluminium oxide bulletproof ceramic plate and its mold and
Preparation method, the arc silicon nitride ceramic plate for using particular manufacturing craft to prepare interior thickness as 6mm or 8mm.In patent CN202109824U
A kind of large scale aluminium oxide bulletproof ceramic plate is disclosed to avoid and make pottery using fritter using whole piece arc alumina ceramic plate
The bad security risk of porcelain plate seam crossing bulletproof effect.But this single layer bulletproof composite efficiency is good not as good as MULTILAYER COMPOSITE effect.
A kind of layer-built armor SiC ceramic thin layer bullet resistant material and preparation method thereof is disclosed in patent CN103964854B, using more
Piece lamination prepares bulletproof ceramic plate, but multi-disc lamination bring greatest problem is to need one layer of one layer of ceramics in large-scale production
Organic material is compound, needs to heat in compound tense organic material, and pressurization suppress compound after organic material softening, with folded
The piece number of plies increases, and it is for example just initially R400 that arc radius, which can be continuously increased, and when reaching 10mm to laminated thickness, R just becomes
410mm can not constantly change pressure head, such as primary pressure 2mm in actual production, and second of pressure head will be changed to R402mm, no
Then easily cause ceramic sheet by pressure break.If being changed to the problems such as more hot press compactings can bring adjustment pressure head, preheating, shadow
Efficiency is rung, and generates the problems such as thermal energy waste is big.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of MULTILAYER COMPOSITEs integrally to wait arcs silicon nitride
Bulletproof ceramic plate, composite effect is good, and good toughness is unlikely to deform, and more fitting Human Physiology curve, comfortable wearing, bulletproof effect are excellent
In single layer bulletproof ceramic plate.
MULTILAYER COMPOSITE described in the utility model integrally equal arcs silicon nitride bulletproof ceramic plate, including plate body, plate body is by nitrogen
SiClx ceramic wafer and high-molecular organic material are alternately bonded, and outermost layer and innermost layer are high-molecular organic material layer；The nitrogen
The SiClx ceramic wafer number of plies is 2-5 layers, preferably 3 layers.
Monolithic silicon nitride ceramic plate is whole piece arc silicon nitride ceramic plate, and inside and outside two sides cambered surface radius is equal.
The size of monolithic silicon nitride ceramic plate is high 400mm, wide 250mm, interior thickness 1-2mm.
The internal and external cambered surface radius of silicon nitride ceramic plate is 400mm.
4 angles of silicon nitride ceramic plate are equipped with chamfering, when wearing, two angles below ceramic wafer be short transverse and
Width direction is the chamfering of 20mm, and two angles above ceramic wafer are short transverse 40mm, and the chamfering of width direction 20mm is worn
Above, more coincided with human body physiological curve, wearing are more comfortable for Dai Shi great chamfering.
Silicon nitride ceramic plate and high-molecular organic material shape are coincide.
Plate shape and human chest, abdomen or the physiological curve at back are coincide.
Preferably, high molecular material is aramid fiber or high molecular polythene, with a thickness of 2mm.
When synthesizing plate body, the mixture of carbon fiber and Ceramic adhesive is uniformly coated in silicon nitride ceramics plate surface, according to
One layer of high-molecular organic material, one layer of silicon nitride ceramic plate mode be superimposed, the number of plies of silicon nitride ceramic plate is 2-5 layers, and most
Internal layer and outermost layer are high-molecular organic material layer, then by hot pressing machine platform, by high-molecular organic material and silicon nitride
Ceramic wafer is heated to 100-120 DEG C, pressurizes compound, obtains MULTILAYER COMPOSITE and integrally waits arcs silicon nitride bulletproof ceramic plate.
When wearing, according to big chamfering in upper direction, integrally arcs silicon nitride bulletproof ceramic plate is waited to insert MULTILAYER COMPOSITE
Enter bullet-proof vest.
The prior art is compared, and the utility model has the advantage that
It is compound that the utility model uses the silicon nitride ceramic plate of the radians such as multilayer full wafer to replace with high-molecular organic material, multiple
Conjunction effect is good, and good toughness is unlikely to deform, and bulletproof effect is better than single layer bulletproof ceramic plate；And to the size of silicon nitride ceramic plate into
Row optimization, makes its human chest, abdomen or the physiological curve at back more coincide, more comfortable when wearing.
