Description
Art
The invention belongs to individual protection armour material field.Particularly relate to a kind of light flexible liquid stab-proof material and preparation method thereof.
Background technology
Along with society and scientific and technological development, stab-resistant material has entered in daily life.The requirement of people to stab-resistant material is more and more higher, and heavy hard stab-resistance body armor can not meet the needs of people, so there is semi-rigid stab-resistance body armor.Semi-rigid stab-resistance body armor has certain flexible stab-resistance body armor, and this stab-resistance body armor is composited by several layer material, and there are one deck or which floor special sheet metal or wire loop interlayer in centre, and this stab-resistance body armor substantially increases the flexibility of people's activity.There are again soft stab-resistant clothes in nearly decades, the soft stab-resistant material of current domestic and international existing tradition, generally be made up of 20-40 layer aramid fiber or superhigh molecular weight polyethylene fibers fabric, because the number of plies is more, still have that cost of manufacture is high, quality is heavy, the shortcoming such as very flexible and comfortableness difference.
Shear thickening liquid is that STF (STF) is made up of dispersed phase particles and decentralized medium, is a kind of non-Newtonian behavior reversible fluid, in the state of the equilibrium, shows as disperse colloidal form; And when high shear effect, its viscosity sharply increases, show solid behavior.Have been reported to the technology of preparing preparing soft stab-resistant clothes and ballistic protective clothing about utilizing shear thickening liquid.Such as, Chinese patent, Cao CN200710075526.6 Hai Lin etc., " soft stab-resistant material and soft stab-proof composite construction " discloses a kind of soft stab-proof material, its principal character comprise by the liquid infiltration compound of shear thickening behavior or coating compound method to prepare flexible puncture-proof material; And then adopt the mode of multiple-layer stacked to be prepared into high-performance soft stab-proof composite obtained liquid composite anti-stabbing material.Chinese patent, CN200710122028.2 discloses a kind of bulletproof stab-resistant clothes of Liquidity material, its principal character comprise make with the hard nanometer particle suspension with shear thickening behavior STF dipping high strength fibre woven fabric, knitted fabric, supatex fabric single or multiple lift superposition make; Bulletproof anti-puncturing material is connected to inner side or the interlayer of outer cover by outer cover thread gluing adhesion and button mounting mode.In above method, all do not mention by shear thickening liquid filling and sealing in fabric, and in preparation process, adopt three-dimensional hollow fabric construction and hot stitching process.
Summary of the invention
Present invention incorporates three-dimensional hollow fabric construction, shear thickening mechanism, without technical advantages such as latitude Bu Rere sewing, technique is simple, easy to operate, the present invention can provide better wearability, and have significant advantage on performance, weight and thickness on the basis ensureing anti-stab performance.
Technical problem to be solved by this invention is to provide
This patent solves the technical scheme that its technical problem adopts:
Preparation has the liquid of remarkable shear thickening behavior, and wherein a kind of formula (mass ratio) is as follows:
Nano-level sphere silica 50-70%
Polyethylene glycol 30-50%
Being combined high strength fibre by hot stitching process without latitude cloth and three-dimensional hollow fiber fabric, makes the pouch-type sealing fabric of Anti-leakage.
The liquid proportional with shear thickening behavior prepared is divided in the pouch-type sealing fabric slowly loading for three times and make, namely make light flexible liquid stab-proof material.Wherein a kind of formula (volume ratio) is as follows:
Shear thickening liquid 30-70%
Pouch-type sealing fabric 40-60%
The beneficial effect of this patent is:
The privileged sites such as 1, given full play to the characteristic of STF, time under normal temperature state, softness is next to the skin, energy available protecting knee joint.
2, not only fully apply the good compression elasticity of three-dimensional hollow fabric construction, namely fabric has excellent cushioning effect to impact energy; Also it can be used as integraty framework material, play a humidification.
3, make full use of the advantage of hot stitching process, solve the infiltration problem of shear thickening liquid, can prepare according to concrete practical situations lightweight, cost is low, the stab-resistant material of soft quality.
The present invention and other modes utilize shear thickening liquid to prepare soft stab-resistant and take and the difference of ballistic protective clothing etc. is to adopt three-dimensional hollow structure and hot stitching process, avoid the situation of the shear thickening liquid uneven distribution produced due to dipping or coating processes, combine the characteristic having played shear thickening liquid and three-dimensional hollow fabric construction to greatest extent, obtain a kind of light flexible liquid stab-proof material.
