The puncture-proof and shock-resisting material provided by the invention has the advantages that the material is flexiable and light, the puncture-proof shock resistance is good, protective property of the material is realized, a stratification phenomenon generated during a using process of the material is effectively prevented, the material can be manufactured into different thicknesses to meet different protective using requirements, and the material can be taken as the material for body safety protecting equipment.
Description
Technical field
The present invention relates to a kind of security protection material, relate in particular 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 toughness slightly, and during high-speed condition, huge change occurs apparent viscosity, become a kind solid matter, and this process has invertibity.Its this specific character makes it when being subject to clashing into higher than specific speed, and hardening is rapidly clashed into after elimination, can be returned to original state again.Utilize shear thickening fluid and fibrous material compound, have good anti-stab shock resistance, shear thickening fluid composite has been obtained extensive use in protective materials field.
Maximum method that existing shear thickening fluid composite is made use be by textile impregnation in the dilution of shear thickening fluid and alcohol, liquid to be diluted takes out removal alcohol after fully entering fabric, obtains shear thickening fluid composite.
Simple one deck fabric is after dipping, and anti-stab shock resistance improves greatly, but does not reach requirement of shelter, must use multiple-layer stacked.Simple multiple-layer stacked composite in use there will be lamination, reduces barrier propterty and the service life of material, if directly multilayer material is sewed up, and can be because the features such as material is difficult to penetrate make processing difficulties.In addition, although simple shear thickening fluid composite can hardening after being impacted, increase lifting surface area, slow down impact strength, it lacks energy snubber absorbed layer, and surge guard performance is limited.Therefore, be badly in need of a kind of in use stable performance, the shear thickening fluid composite that not stratified and protection effect is good.
Summary of the invention
Object of the present invention, exactly in order to address the above problem, provides a kind of in use stable performance, the anti-stab anti-ballistic materials that not stratified and protection effect is good.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of anti-stab anti-ballistic materials, comprise at least two-layer softgel shell construction unit and one deck impact kinetic energy absorbed layer at least, each impact kinetic energy absorbed layer is clipped in respectively between two-layer softgel shell construction unit and with described two-layer softgel shell construction unit bonding and is connected; Described softgel shell construction unit, by the multilayer shear thickening fluid composite internal layer that forms stacked together,, is sewed up and is formed by connecting by suture as surrounding layer by impermeabilisation high density flexible coated fabric; Described impact kinetic energy absorbed layer is flexible material layer.
