Abstract
The invention relates to a method for producing an anti-fragmentation helmet from high-strength and high-modulus polyethylene laid fabric, which comprises the following steps: selecting 30-35 layers of high-strength and high-modulus polyethylene laid fabric flaky materials, and cutting the materials according to the required helmet size; regularly superimposing the materials, and softening the adhesives in the materials for 30-40 minutes under the condition of 80 DEG C-90 DEG C; putting the materials into a hot pressing mold for 20-25 minutes under the conditions that the pressure is 20-25MPa and the constant temperature is 130 DEG C-135 DEG C, and keeping the pressure; and taking the materials out of the hot pressing mold, and then quickly putting the materials into a cold pressing mold for forming for 20-25 minutes under the condition that the pressure is 20-25MPa to obtain a semi-finished product helmet. The invention overcomes the defects that the whole production processes are completed by one mold, the mold needs to be heated and cooled repeatedly, and the energy is consumed. In the invention, the high-strength and high-modulus polyethylene laid fabric is adopted; a helmet product can resist the shrapnel which spatters at high speed; and the whole production processes of the helmet do not need to heat and cool the hot pressing mold repeatedly, thereby simplifying processes, improving production benefit and reducing production cost.
Description
Technical field
The present invention relates to helmet production method, specifically is that a kind of high-strength high-modulus polyethylene does not have the latitude fragmentation helmet production method of deploying troops on garrison duty.
Background technology
Because scientific and technological progress, weaponry is brought in constant renewal in, and both sides at war are all based at a distance, and uses the big bomb of power in a large number, so, how to ensure fighting capacity, ensures that especially the safety of doing war personnel head has just become key subject.As everyone knows, current major part is also using steel helmet to carry out individual protection.Its principal element is a low price.The shortcoming of steel helmet maximum is exactly that weight is big, and it is heavy to dress personnel's load, and causes easily and play fragment and strike on the steel helmet and can be splashed on one's body the other staff, and this has just caused the secondary injury.Developed country has all adopted the nonmetal compound helmet to replace steel helmet, the most generally is the woven cloth that raw material makes with the aramid fiber, and thermosetting resin applies the compound helmet of the hot-forming gained in back.Because the core technology of making aramid fiber also being monopolized by du pont company and Dutch Aksu company, is used also very limited by market in a large number.Especially equip an army and be subjected to restriction.In addition, the price comparison costliness of aramid fiber also is to be difficult to the main cause accepted by market.
Along with the national power of China constantly promotes, it is independent to have advocated national defence, the most essential is that weaponry is independent, bases on our country.China's high-strength high-modulus polyethylene fiber industry is constantly brought forth new ideas at present, and its quality reaches the requirement of anti-fragmentation far away.High-strength high-modulus polyethylene fiber has in light weight, the intensity height, the modulus height is that intensity is the highest in the current high-performance fiber, be equivalent to wait steel heavy more than 10 times.Studies show that high-strength high-modulus polyethylene fiber does not have latitude cloth, be called for short the energy that absorption shell fragment high-speed impact that " UD material " can be very fast produces, from but make the compound helmet preferred material of lightweight.
At present, the technology of the existing compacting helmet, this technology all is to finish on a press die. the mould of the helmet is for keeping stiffness, and matrix is all done very greatly, and repeatedly its mould is heated up, cooling will cause hot benefit loss, drawback is that energy consumption is big, and the production cycle is long, and industrial production efficiency is low.And back processing paint also is difficult to apply.
Summary of the invention
At the deficiency of above-mentioned similar technology, the invention provides a kind of high-strength high-modulus polyethylene does not have the latitude fragmentation helmet production method of deploying troops on garrison duty.It is relatively more expensive that this method has solved employing aramid fiber cost of material, and adopt high-strength high-modulus polyethylene not have latitude cloth, and whole production is all finished on a press die, needs repeatedly press die to be heated up, and cooling causes the technical problem that energy consumption is big, production efficiency is low.
Technical scheme of the present invention is as follows:
(1) choosing the strong high-modulus polyethylene of 30-35 floor height does not have latitude cloth tablet material, and size can be cut out according to required helmet size;
(2) above-mentioned material is neatly superimposed, put into thermostatic box, preheating under 80 ℃ of-90 ℃ of conditions, made that the adhesive in the material was softening in 30-40 minute;
(3) above-mentioned neat superimposed material is put into the hot pressing die of press, pressure 20-25Mpa, 130 ℃-135 ℃ of constant temperature kept 20-25 minute, as pressure release, timely supplementary pressure;
(4) take out hot base substrate, put into the cold stamping die typing rapidly, its pressure 20-25Mpa kept 20-25 minute, thereby obtains the semi-finished product helmet.
For the ease of helmet coating, improve PASS, can not have latitude cloth tablet material two sides at the strong high-modulus polyethylene of 30-35 floor height in the above-mentioned steps (1) and cover with the woven cloth of high strength glass fiber.
The density of the woven cloth of above-mentioned high strength glass fiber is preferably 200g-400g/m
2
The present invention has following advantage: the present invention is owing to adopt high-strength high-modulus polyethylene not have the latitude cloth material, the helmet of producing can effectively be resisted the shell fragment that splashes at a high speed, and needn't be when the whole helmet is produced to the hot pressing die cooling that heats up repeatedly, thereby simplified technology, improve productivity effect, reduced production cost.
The specific embodiment
Embodiment 1:
At first choosing high-strength high-modulus polyethylene does not have the latitude cloth material, is called for short the UD material, 30 layers of tablet, and this tablet should be cut out by required helmet size, and the two sides is 200g-400g/m with density
2The woven cloth of high strength glass fiber cover so that helmet coating improves PASS, the woven cloth of this kind high strength glass fiber market can be bought, as producers such as Nanjing glass fibre chemical research institutes.
The UD material that above-mentioned two sides is coated with the woven cloth of high strength is under 80 ℃ of conditions, softening through 30 minutes, make UD material thermally equivalent under identical conditions, fully softening to adhesive, put under the hot pressing die 25Mpa pressure, 130 ℃ of temperature, hot pressing in 20 minutes keep-ups pressure, taking-up is put into cold stamping die rapidly and is finalized the design, under the same 25Mpa pressure, 20 minutes, take out base substrate and promptly get the semi-finished product helmet.
