Description
Technical field
The present invention relates to a kind of security protection material, particularly relate to a kind of anti-stab anti-ballistic materials.
Background technology
Shear thickening fluid is a kind of non-Newtonian fluid, when low-speed conditions, has slightly toughness, during high-speed condition,
There is huge change in apparent viscosity, becomes a kind solid matter, and this process has reversibility.It this
Characteristic make its when by clashing into higher than specific speed, can be the most hardening, clash into after eliminating, can be returned to again originally
State.Utilize shear thickening fluid to be combined with fibrous material, there is good anti-stab shock resistance, shear thickening
Fluid composite has been achieved with extensively applying in protective material field.
Most method that existing shear thickening fluid composite makes is that fabric is impregnated into shear thickening
Fluid is with the diluent of ethanol, and liquid to be diluted removes ethanol well into taking out after fabric, obtains shear thickening stream
Composite material.
After one layer of simple fabric is through impregnation with, anti-stab shock resistance is greatly improved, but does not reaches requirement of shelter,
Multiple-layer stacked must be used.Simple multiple-layer stacked composite in use there will be lamination, reduces
The barrier propterty of material and service life, if directly being sewed up by multilayer material, can be difficult to, due to material, features such as penetrating
Make processing difficulties.It addition, although simple shear thickening fluid composite can be hardening after being impacted,
Increase lifting surface area, slow down impact strength, but it lacks energy snubber absorbed layer, surge guard limited capacity.
Therefore, be badly in need of a kind of in use stable performance, the shear thickening fluid that not stratified and protection effect is good is combined
Material.
Summary of the invention
The purpose of the present invention, it is simply that in order to solve the problems referred to above, it is provided that one in use stable performance, no
Layering and the good anti-stab anti-ballistic materials of protection effect.
In order to achieve the above object, present invention employs techniques below scheme: a kind of anti-stab anti-ballistic materials, including
At least two-layer softgel shell construction unit and at least one of which impact kinetic energy absorbed layer, each impact kinetic energy absorbed layer is clipped in two respectively
It is connected between layer softgel shell construction unit and with described two-layer softgel shell construction unit bonding；Described softgel shell construction unit is by many
Layer shear thickening fluid composite composition stacked together internal layer, is made by impermeabilisation high density flexible coated fabric
For surrounding layer, it is formed by connecting by suture；Described impact kinetic energy absorbed layer is flexible material layer.
Described shear thickening fluid composite is formed through shear thickening fluid dipping by fabric.
One or more in woven fabric, knitted fabric, non-weaving cloth of described fabric.
Described shear thickening fluid by the hard nanometer spheroidal particle that particle diameter is 10nm-1 μm with molecular weight is
The Polyethylene Glycol of 200-400 goes bubble removing to prepare by putting into after mechanical agitation in Ultrasound Instrument, wherein, and nanometer spherical
The weight/mass percentage composition of particle is 20-85%.
Described hard nanometer spheroidal particle is silicon dioxide granule or calcium carbonate particle.
The material of described fabric is selected from one or both in aramid fiber, ultra-high molecular weight polyethylene.
The material of described suture is selected from high-strength polyester, aramid fiber, ultra-high molecular weight polyethylene, the one of high performance nylon
Or it is multiple.
Described flexible material is selected from wool textile, polyurathamc or polyvinyl butyral.
Described bonding be connected adhesive used selected from adhesive for polyurethane, rubber adhesive, epoxy resin adhesive,
One in phenolic resin adhesive, organic silica gel adhesive.
Being bondd by three layers of softgel shell construction unit and two-layer wool felt epoxy resin adhesive and form, therein shearing increases
Thick fluid composite is four layers.
The internal layer of the softgel shell construction unit in the present invention uses shear thickening fluid composite, two softgel shell construction units
Between accompany impact kinetic energy absorbed layer, adhesive bond, soft and light, anti-stab shock resistance is good, not only real
Show the barrier propterty of material, and can effectively prevent the lamination during materials'use from occurring, can make
The protective material that more thickeies and do not increase difficulty of processing.Different-thickness can be fabricated to and reach different protection use need
Ask, can serve as human-body safety protective gear material.
