Abstract
The present invention produces light bulletproof plate of different shapes by thermally pressing superhigh molecular weight polythene and the said bulletproof plate can resist high-grade bullets, such as some steel bulltes of miniature tommy gun and rifle. The said bulletproof plate produces no bounce of hitting bullet, weighs only one third of steel plate ,is stainless and can prevent various penetrating damage. With good bulletproof effect, it is used in bulletproof jacket, bullet shield, helmat, car, suitcase and door and window.
Description
The invention belongs to the guard technology field, particularly a kind of ultra-high molecular weight polyethylene HB series material that utilizes, the lightweight bulletproof template that the process hot pressing is made and the application of other goods in protection.
At present, domesticly be used for anti-high-level bullet, mostly be steel plate, ceramic wafer, alloy sheets etc. as the bullet resistant material of seven or nine mini-submachine gun steel core bullets or five or six formula rifle steel core bullets.These materials are all very heavy, and ricochet easily takes place, and steel plate easily gets rusty, and ceramic wafer is easily cracked, can only bear an attack.Be used for driving the material of anti-this type of high strength bullet abroad, except that above-mentioned material, also used some composite plates, but weight is all very heavy, and bulletproof effect be poor, and obvious internal injury is arranged.
The purpose of this invention is to provide a kind of bulletproof ability by force, the not moulding process and the application process on flak jackets, shellproof shield, the helmet, automobile, briefcase, door and window and other protective article of ricochet, lightweight lightweight bulletproof template.
The present invention adopts ultra-high molecular weight polyethylene, and strand is parallel-oriented, has the HB series material of high-crystallinity, and this fiber has high intensity.This material through superimposed in order → precompressed → constant temperature hot pressing → cooling, is made the template of required form.
Superimposed in order: shape as required with some of superhigh molecular weight polyethylene material nonwoven cutting successively, is superimposed together then in order;
Precompressed: superimposed superhigh molecular weight polyethylene material non-woven fabric plate put into be warming up to 110---120 ℃ mould, 10 tons in addition---20 pressure, repeatedly repeat pressurization, to get rid of the gas between non-woven fabric plate;
Hot pressing: pressure is risen to 200 tons, and mold temperature rises to 125---and 130 ℃, constant temperature, constant voltage 10---20 minutes;
Cooling: under constant voltage, mold temperature is reduced to about 60 ℃ gradually, slowly be depressurized to below 40 ℃, can open mould, take out the moulding armour.
The lightweight bulletproof template of making by above-mentioned technology, by test, can not only be with missile, as damages such as bullets, and can absorb, spread the missile energy remaining, elastic stored energy is good, almost can be with whole depleted of energy of missile, make the energy of contact human body be reduced to bottom line, reach shellproof, can defend the purpose of non-transfixion damage again.
The lightweight bulletproof plate that the present invention makes can be prevented high level bullet, as seven or nine mini-submachine gun steel core bullets or five or six formula rifle steel core bullets.Do not resemble behind this type of plate of attack and make human body that various non-transfixion damages, i.e. internal injury take place steel plate, the composite plate.This type of plate weight only is 1/3rd of equal shellproof level steel plate.Advantages such as ricochet, non-corrosive do not take place after having attack.
The lightweight bulletproof plate that the present invention makes is assemblied on the soft bullet-resistant garment, with in case high level bullet impact (five or six formula rifle steel core bullet), its shellproof mechanism is: by the lightweight bulletproof plate with its high energy missile damage, energy-absorbing, soft bullet-resistant garment is with the absorption of missile energy remaining process, diffusion, elastic stored energy, its energy is all exhausted, be reduced to bottom line so that be passed to the energy of body at last; So both reach anti-bullet, can prevent the purpose of non-transfixion damage again.The lightweight bulletproof plate that the present invention makes is applied to various vehicles, makes it to become the bulletproof car of appropriate level, because this type of plate weight ratio steel plate is light, is contained in arrangements for automotive doors etc. and locates, and connecting portion is played the certain protection effect, increases the service life; This type of plate also can be used for making the ballistic performance that briefcase, door and window make it to have appropriate level.
For two example two:
Ultra-high molecular weight polyethylene HB series material is cut into required form,---60 layers, mould being warming up to 110---120 ℃ that be overlapped into 40 in order then put the HB series material of folding in the automotive trim mould into, depress with 10 tons of pressure, mention mold again, depress the air in getting rid of material again, mould is warming up to 125---and 130 ℃, pressure rises more than 200 tons, constant temperature and pressure 15 minutes slowly cools the temperature to 60 ℃, keeps 200 tons of constant voltages during this; Slowly release then, when temperature was reduced to 40 ℃, moulding material was taken out in die sinking, and this moulding material is installed in the automobile, becomes automotive trim panel, and this plate has the function of anti-high-level bullet, makes institute's decorations automobile become bulletproof car.
The HB series material is cut into required area, is overlapped into 40 in order then---60 layers (the concrete number of plies is by shellproof rank requirement) is warming up to 110 with flak jackets template mould---and 120 ℃, put the HB series material of folding into mould, depress with 10 tons of pressure, mention mold again, press again, air in getting rid of material, mould is warming up to 125---and 130 ℃, pressure rises to 200 tons, constant temperature and pressure 15 minutes, slowly cool the temperature to 60 ℃, keep 200 tons of constant voltages during this; Slowly release then, when temperature was reduced to 40 ℃, moulding material was taken out in die sinking, and this profiled sheeting is assembled on the soft bullet-proof vest, constitutes organic shellproof system with soft bullet-proof vest, in order to resist high level bullet, as five or six formula rifle steel core bullets.
Claims (2)
1, the application of superhigh molecular weight polyethylene material in ballistic-resistant article, it is characterized in that 40--80 sheet ultra-high molecular weight polyethylene nonwoven, through difform template or the goods that hot pressing is made, be used for flak jackets, shellproof shield, the helmet, briefcase, door and window and other protective article.
2, the application of superhigh molecular weight polyethylene material according to claim 1 in ballistic-resistant article is characterized in that hot pressing technique makes template or goods for superimposed in order → precompressed → constant temperature hot pressing → cooling; Shape as required, with ultra-high molecular weight polyethylene nonwoven cutting 40-80 sheet successively, stack in order then, put into the mould that temperature rises to 110-120 ℃, the pressure of 10-20 ton in addition, after repeatedly repeating precompressed, again mold temperature is risen to 125-130 ℃ of constant temperature, in addition 200 tons pressure, constant voltage 10-15 minute, be cooled to 60 ℃ then, slow removal pressure takes out below the temperature to 40 ℃.
