The invention discloses a kind of production methods of bulletproof ceramic plate, by the way that the back side of permeable fiber cloth to be attached to the convex surface of molding die, using slip casting in molding die molding ceramic green；Make to be distributed several salient points on the concave surface of ceramic green；Ceramic dry body is obtained after drying；Finally sinter ceramic plate into.This method is prefabricated to bulletproof ceramic surface to form equally distributed salient point, to carry out Nian Jie compound tense with bigger gluing area with polyethylene board in bulletproof ceramic plate, salient point can inhibit the sliding between potsherd and polyethylene board simultaneously, the peeling for increasing sticking effect, reducing potsherd, improves the safety of bulletproof flashboards.
Description
Technical field
The invention belongs to ceramic field shaping techniques, are related to a kind of molding method for preparing of bulletproof ceramic plate.
Background technique
The burster course of bulletproof flashboards generallys use polyethylene board at present and ceramic plate is compound, and ceramic plate is passed through glue
It being bonded on the outside of polyethylene board plate, compression can be firmly combined, and this composite inserting not only has preferable bulletproof effect, and
And the comfort of wearing is preferable.It is relatively smooth usually to carry out compound bulletproof ceramic surface, using glue by bulletproof ceramic with
It needs negative pressure to compress the adhesion strength to guarantee ceramic wafer Yu polyethylene board plate in polyethylene board plate bonding process, carrys out anti-anti-avulsion
It falls.
Bulletproof ceramic mainly has two methods of the splicing of fritter ceramics and monolithic ceramic formula to be answered in bulletproof flashboards at this stage
It closes.Bulletproof flashboards spliced for fritter occur fritter potsherd bonding in use and peel off and will be formed to bulletproof flashboards
Fatal defect poses a serious threat soldier's life.And occur in use for monolithic ceramic formula bulletproof flashboards
After ceramic wafer and the removing of polyethylene board plate, easily causes entire plate all to rupture when by bullet strike, cause to prevent in this way
The anti-rounds ability of diving board declines to a great extent.
National IP Network discloses the production method of a kind of bulletproof flashboards and composite bulletproof flashboard at present, in this method
On the outside of the backboard that fritter bulletproof ceramic is pasted to polyethylene board first, bulletproof ceramic pressure then will be pasted by compression apparatus
Tightly, guarantee the adhesive strength of junction.This method is usually that fritter bulletproof ceramic sheet is spliced into one piece of whole armour, is used
The mode of this fritter ceramics splicing, which carries out compound bulletproof flashboards, becomes what bullet penetrated in the seam crossing of fritter potsherd
Weak spot, and potsherd appearance Nian Jie with polyethylene board is peeled off and will be caused to soldier's life serious as fatal disadvantage
It threatens.
Also paid at present to ping mold to form and make monolith bulletproof flashboards, make its rough surface a bit, one
Determine in degree increase gluing area, thus with polyethylene board bond it is stronger, but the Mold Making it is extremely difficult and at
This height；Secondly monolith bulletproof flashboards after molding are easy to sticking to mould, to directly damage when green body being caused to demould.
Summary of the invention
The technical problem to be solved by the present invention is to it is equally distributed convex to provide the prefabricated formation in a kind of pair of bulletproof ceramic surface
Point, to carry out Nian Jie compound tense with bigger gluing area with polyethylene board in bulletproof ceramic plate, while salient point can press down
Sliding between potting tile and polyethylene board, the peeling for increasing sticking effect, reducing potsherd, improves the peace of bulletproof flashboards
The production method of the bulletproof ceramic plate of full property.
The technical scheme is that a kind of a kind of production method of bulletproof ceramic plate with following methods is provided,
It the following steps are included:
(1) several equally distributed concave points are suppressed on the front of permeable fiber cloth, pressed permeable fiber cloth
Several concave points are evenly distributed on front；
(2) after the permeable fiber cloth of pressed monolith getting wet, the back side of permeable fiber cloth is attached to the convex of molding die
Face, the convex surface of the molding die correspond to the concave surface of ceramic body with PE plate phase gluing after shaping, the permeable fiber cloth at
It is closed using face and face paste on the convex surface of pattern tool；
(3) slip casting molding ceramic green in molding die is used；
(4) after demoulding, ceramic green is placed on liner plate, the one of permeable fiber cloth will be posted and placed upwardly, torn
Permeable fiber cloth is distributed several salient points on the concave surface of ceramic green at this time；
(5) after ceramic green being dried at room temperature for 5~48h, dry 5 in 50~110 DEG C of baking ovens~obtain ceramics for 24 hours
Dry body；
(6) finally by ceramic dry body as sintering kiln roasting, temperature is 1450~2200 DEG C when firing, heat preservation 0.5~
3h cools down to obtain ceramic plate with furnace.
The compacting of the step (1) is printed using roller printing machine or is printed to roller embossing machine, the rolling of roller printing machine
On cylinder or to the salient point for being equipped with several same intervals on the outside of the print roller of roller printing machine.
The permeable fiber cloth uses any one of nylon cloth, non-woven fabrics, geotextiles, cellulosic filter paper, kapok paper.
The dot shape be semicircle, circular cone, diamond shape, it is rectangular in any shape.
The permeable fiber cloth with a thickness of 0.1~2mm.
The injection forming is any one of common pressure grouting molding, high-pressure slip-casting molding, gel casting forming.
The bulletproof ceramic plate is any in aluminium oxide, silicon carbide and boron carbide ceramics.
The bulletproof ceramic plate is whole one piece or by spliced together.
The step the molding of upper die and lower die fit part permeable fiber cloth thickness and be attached to molding die
Convex surface permeable fiber cloth consistency of thickness.
After above step, compared with prior art, have the advantage that is made by permeable fiber cloth the technology of the present invention
Bulletproof ceramic surface forms equally distributed salient point, so that the gluing area of ceramic plate and PE plate compound tense is significantly increased
Method, this method, which can enhance adhesive effect, reduce potsherd falls off.By the way that the recessed of certain specification will be printed in fiber cloth
Point attaches it to molding die inner wall, so that the ceramic plate surface molded is uniformly distributed similar salient point, this method
Can be suitably used for the preparation methods such as high-pressure slip-casting molding, common pressure grouting molding, gel casting forming, applicability is wide, it is easy to operate,
It is at low cost；It can be processed on original mold simultaneously, not increase the production cost of enterprise.
As an improvement, the roller printing machine that the compacting of the step (1) uses is printed or is printed to roller embossing machine, it is described
On the roller of roller printing machine or to the salient point for being equipped with several same intervals on the lateral wall of the roller of roller printing machine, adopt
Permeable fiber cloth is processed with both methods, high-efficient, salient point is evenly distributed.
As an improvement, the step (2) the molding of upper die and lower die fit part permeable fiber cloth thickness with
It is attached to the consistency of thickness of the permeable fiber cloth on the convex surface of molding die, since mold is upper and lower two die cavitys, is pasting permeable fiber
Cloth is not only bonded with mould surface, while also having one layer of permeable fiber cloth in land area, in this way molding rear mold total height
It increases and is equivalent to one layer of permeable fiber cloth thickness, so not influenced on molding blank size finally.
