Abstract
The utility model relaters to a large-dimension aluminum oxide bulletproof ceramic plate. A plate body is a whole piece of arc-shaped aluminum oxide ceramic plate and is fine and compact, and the periphery of the large-dimension aluminum oxide bulletproof ceramic plate is in smooth transition; the arc surface radius of the inner surface is equal to that of the outer surface of the plate body; and the dimension of the plate body is 300-400 mm*250-300 mm*2-8 mm. The plate body is matched with a chest, an abdomen or a back part of a human body in shape; the shape of the plate body is also matched with the physiological curve of the chest, and the abdomen or the back part of the human body. Arc surfaces of the front surface and the back surface of the plate body can cling to a back plate made of fiber composite materials so as to form the whole piece of arc-shaped large-dimension aluminum oxide bulletproof ceramic plate. The large-dimension aluminum oxide bulletproof ceramic plate can be comfortable to wear, does not affect the normal activities and can be worn and used on various occasions. The large-dimension aluminum oxide bulletproof ceramic plate has high protection grade, and the protection performance of the large-dimension aluminum oxide bulletproof ceramic plate is superior to that of a small sheet-shaped embedded and spliced bulletproof plug-in board made of the same materials. The large-dimension aluminum oxide bulletproof ceramic plate reduces the labor intensity and the cost in the manufacturing process, improves the production efficiency and completely puts the potential safety hazard of bad bulletproof effect at the commissure of the small ceramic plate to an end.
Description
Technical field
The invention belongs to the ceramic field, relate in particular to and be applicable to a kind of large scale aluminium oxide bulletproof ceramic plate of making ballistic panel.
Background technology
The human body flak jackets is the protective gear that individual soldier soldier, People's Armed Police, security personnel, arms supercargo use always, belongs to dual-use product.The core component of human body flak jackets is a bulletproof flashboards, and the plate material has experienced hard metal plate, soft synthetic fibers plate, has developed into the compound plate of third generation pottery/synthetic fibers at present, is the main developing direction of present flak jackets.Compound plate backboard adopts aramid fiber or super high molecular weight high-strength high-modulus polyethylene fiber composite to process.Ballistic panel mainly contains aluminium oxide, carborundum, boron carbide and boron carbide/titanium boride/materials such as silicon carbide compound pottery.
The shellproof backboard of bulletproof ceramic panel and macromolecule is combined through the transition adhesive linkage, and when pasting one deck crack arrest cloth on ceramic panel surface and preventing that pottery is broken to the injury of human body, just obtain third generation bulletproof composite plate.
In order to obtain to meet the arcuate shape of human chest, the present bulletproof flashboards of China is a blockage ceramic wafer of processing 50mm * 50mm earlier, and the camber plate is pasted in splicing on preformed arc synthetic fibers backboard again.
The problem that exists, the one, need the processing of precision mill is carried out on every fritter pottery four limits, cost is significantly increased; The 2nd, the seam crossing bulletproof effect is not good, has potential safety hazard.
The utility model content
The goal of the invention of the utility model is to improve prior art, and a kind of design of large scale aluminium oxide bulletproof ceramic plate is provided.
The application implements through following technical scheme:
Develop a kind of large scale aluminium oxide bulletproof ceramic plate, comprise plate body, it is characterized in that:
Described plate body is a whole piece arc alumina ceramic plate, and plate body is careful closely knit, and periphery is rounding off;
The cambered surface radius on the inside and outside two sides of described plate body equates;
Described plate body is of a size of 300～400mm * 250～300mm * 2～15mm.
Above-mentioned large scale aluminium oxide bulletproof ceramic plate is characterized in that the cambered surface radius on the inside and outside two sides of this plate is 300～500mm.
Above-mentioned large scale aluminium oxide bulletproof ceramic plate is characterized in that plate shape, coincide with the form fit at human chest, belly or back.
Above-mentioned large scale aluminium oxide bulletproof ceramic plate is characterized in that plate shape, coincide with the physiological curve coupling at human chest, belly or back.
The utility model has the advantages that:
1. the utility model is a whole piece arc alumina ceramic plate; Thoroughly eradicated and processed the blockage ceramic wafer in the prior art earlier; The edge that splicing is pasted on preformed arc synthetic fibers backboard is again pieced together process, has reduced labour intensity and cost when making, has improved production efficiency; And thoroughly stopped the not good potential safety hazard of fritter ceramic wafer seam crossing bulletproof effect.
2. the cambered surface of plate body front and back can be fitted with backboard fully, and is comfortable and easy to wear, disguised strong, do not influence the normal activity of wearer, can dress in various social activities, workplace and use.
3. its barrier propterty is superior to general strip and inlays the flak jackets of amalgamation or the soft bullet-resistant garment that the solo fibre composite is processed.
Description of drawings
Fig. 1 is the form sketch map of the utility model large scale aluminium oxide bulletproof ceramic plate;
Fig. 2 is that the A of Fig. 1 is to the form sketch map;
The structural form local enlarged diagram of Fig. 3 after to be the utility model as ballistic panel and the shellproof backboard of macromolecule bonding.
The specific embodiment
Among the figure, the front of 1 integral curved large scale aluminium oxide bulletproof ceramic plate; The back side of 2 integral curved large scale aluminium oxide bulletproof ceramic plates; 3 crack arrest layer of cloths; 4 one deck aramid fibers or super high molecular weight high-strength high-modulus polyethylene fiber composite layer; 5 have identical aramid fiber or super high molecular weight high-strength high-modulus polyethylene fiber composite layer (backboard) that can radius surface with ceramic panel.
Embodiment
1. according to required composition proportion and solid concentration requirement, weighing ceramic powder and additive, but the water base ceramic slurry of preparation gelation, weighing and the corresponding ceramic slurry of mould therefor capacity;
2. prepare special modular mold (separate case application);
3. cast slowly is poured into load weighted ceramic slurry between the template from arc sprue gate, template middle part, slowly rises and be full of at the bottom of die cavity to the arc sprue gate in back, inflow die cavity bottom;
4. the demoulding and cutting gel blanket, template is successively opened in the demoulding behind the gel solidification, and takes out the gel blanket of radius such as internal and external cambered surface;
5. dry, the gel blanket is dry, no longer change until base substrate weight;
6. sintering promptly obtains the whole bulletproof ceramic plate that polylith has radiuses such as same size internal and external cambered surface.
The product that obtains is a whole piece arc alumina ceramic plate, and plate body is careful closely knit, and periphery is rounding off; It positive 1 equates that with the back side 2 arc radius this example is R400mm, is of a size of the integral curved oxidation bulletproof ceramic plate of 300mm (height) * 250mm (wide) * 2mm (interior thickness).
