Description
Technical field
Patent of the present invention is related to a kind of laminated cloth and its technology for producing field, and especially a kind of nano aluminium oxide is combined
Aramid No-Woven Cloth and preparation method thereof, the adhesive used in it with the addition of nano aluminium oxide, and percentage by weight shared by aluminum oxide is
0.5-8.0, resistance to (anti-) impact property of this Composite aramid fiber laminated cloth is good, and it is excellent that resistance to blunt hinders ability.
Background technology
Aramid fiber full name is " PPTA ", and English name is Aramid fiber, is a kind of new
Type high-tech synthetic fibers.Due to containing benzene ring structure in strand, therefore, its strand rigidity is high, fibre strength is big.Its is strong
Degree is 5~6 times of ordinary steel wire, and modulus value is 2~3 times of steel wire or glass fibre, and toughness is 2 times of ordinary steel wire, and is weighed
Amount be only ordinary steel wire 1/5 or so, at a temperature of 560 DEG C, its special molecular chain structure can guarantee that the fiber do not decompose,
Do not melt, and with good insulating properties.
Traditional shellproof nonmetallic materials use Aramid No-Woven Cloth technology substantially, and it is by aramid fiber in equipment such as wrapping machines
On, it is fabricated by by opening up the processes such as silk, impregnation, drying, bulk composition is generally used now for acrylic acid, the solvent of polyurethane
Or aqueous glue carries out impregnation making, these glues are covered on fiber, play a part of anchoring fiber position, make laminated cloth
When by bullet impact, the energy of bullet can be transmitted along fiber, shellproof effect is played.
The performance of aramid fiber is very excellent, with the anti-tensile strength of highest, and very high modulus of elasticity and relatively low ratio are close
Degree, but single aramid fiber can not be shellproof, it is necessary to it is multilayer laminated with the state of cloth with glue produced with combination into laminated cloth
Form by the energy absorption of bullet impact, scattered, play shellproof effect.But due to the mechanical property and aramid fiber of glue
Differ greatly, be greatly affected using Aramid No-Woven Cloth combination property made from above-mentioned technology, be mainly reflected in laminated cloth
Hardness is relatively low, and the creep of laminated cloth is serious i.e. when bullet is incident, and shock resistance is poor, although bullet is not penetrated but caused
Very serious " blunt wound ", the blunt trauma material that can only add the laminated cloth number of plies or the high cost of increase reaches the effect of protection, this
Sample adds the load of wearer.
There is above-mentioned technical characteristic because aramid fiber is spacing, most flak jackets, the helmet, bulletproof armour are mostly used now
Such technology, though the bulletproof device that this material is made has lightweight than steel plate, is easy to carry, manufacturing cost is low excellent
Point, but its hardness for being reached and shock resistance need to be improved.
The content of the invention
