Abstract
The utility model provides a bullet-proof and puncture-proof material which is characterized by comprising an inner layer and an outer layer, wherein a shear thickening fluid layer is arranged between the inner layer and the outer layer, and the edges of the inner and the outer layers are adhered. Compared with the prior art, the bullet-proof and puncture-proof material is excellent in shock resistance and bullet-proof puncture-proof effect, has good toughness, high flexibility and low cost, not only can be used for manufacture of military bullet-proof clothes, bullet-proof breast plates and bullet-proof helmets and but also manufacture of protective devices for protecting human necks and limbs, such as protective clothes for police officers, security personnel and the like.
Description
Technical field
The utility model relates to a kind of bulletproof anti-puncturing material, be specifically related to a kind of shear thickening fluid that utilizes under the effect of impacting, hard nanometer particle is wherein assembled the formation Particle Cluster, so that material hardens, thereby the material of dispersion and impact-absorbing ripple can be extensively as material military, daily security clothes.
Background technology
The common material that adopts of modern military flak jackets is high-tenacity polyethylene fibre, Aramid No-Woven Cloth/or combine with the high-performance ceramic sheet and to make, bulletproof effect is excellent, but it is overweight to have quality, and the shortcoming that flexibility is lower is unfavorable for the fast reaction of soldier in the actual Campaign Process.And because material is too thick and heavy, can only protects the trunk of human body, and can't play to people's four limbs effective protection.Based on this, Chinese patent CN 101140151A " bulletproof stab-resistant clothes of liquid state material ", US Patent No. 7498276B2 " ADVANDED BODY ARMOR UTILIZING SHEAR THICKENING FLUIDS " all propose to adopt the method for shear thickening fluid (STF) impregnation of fibers fabric to improve the pliability of protective materials.In addition, also there is CN102012193 " Multifunctional protective blanket " to be coated on the fabric about shear thickening fluid.
Shear thickening fluid is to be suspended in the non-Newtonian fluid that forms in polyethylene glycol (PEG) solution by hard particles.Hard particles commonly used has silica and other oxides, polymethyl methacrylate and nano-calcium carbonate etc.Nontoxic and its performance of solvent for use polyethylene glycol can keep stable in very wide temperature range.Become a kind of very hard material in the next meeting of the impact of external force.
But the coating of mentioning in above several patent does not have detailed preparation method, and shear thickening fluid is when applying, and needing increases watertight composition, and sealing bag etc. are to avoid occuring the problem that liquid spills.
The utility model is intended to adopt nonwoven and adhesive, non-woven fabrics fiber can be better along the fiber transmission when being subject to impulsive force, and use adhesive between the marginal layer of two-layer adhesive-bonded fabric up and down, to apply, the centre is STF, the fiber of every layer of nonwoven also bonds with adhesive, by the method for flat board compacting, so that adhesive solidifies, STF is sealed in middle.By adhesive treatment, can directly play the effect of watertight composition, prevent the seepage of shear thickening fluid, thereby reduced unnecessary fabric requirement, reduce production stage, reduce weight, improve flexibility.
Summary of the invention
Existing protective garment is thick and heavy in order to overcome for the utility model purpose, very flexible, expensive shortcoming, a kind of novel bulletproof anti-puncturing material is provided, under the condition that does not reduce the protective garment barrier propterty, improve its flexibility, and with cost control in relatively low level.
In order to achieve the above object, the utility model provides a kind of bulletproof anti-puncturing material, it is characterized in that, comprises internal layer and skin, is provided with the shear thickening fluid layer between internal layer and the skin, and internal layer and outer field edge are bonded together by adhesive.
Preferably, described internal layer comprises at least two-layer nonwoven, one-way fiber close-packed arrays arranged side by side in every layer of nonwoven, and the fiber direction of two-layer nonwoven intersects mutually at least.
More preferably, the angle between the fiber direction of described at least two-layer nonwoven is 0 °, 45 ° or 90 °.
Shear thickening fluid described in the utility model for particle size be the nanometer grade silica particle of 10～50nm to be dispersed in molecular weight through ultrasonication be the non newtonian type liquid that obtains in 200 the polyethylene glycol, the mass fraction of nanometer grade silica particle is 25-80%.The nonwoven of described skin and internal layer is made by high-performance fiber such as aramid fiber or high-strength high-modulus polyethylene fiber.Described internal layer and the outer edge employed adhesive that bonds is that polyethylene glue, epoxide-resin glue, phenolic resin glue, polyvinyl chloride glue etc. are usually used in the especially bonding adhesive of macromolecular fibre of high molecular products.
Compared with prior art; the utlity model has excellent shock resistance and shellproof anti-puncture effect; its pliability is good, flexibility is high, cost is low; except being used for making military flak jackets; shellproof plastron; outside the bulletproof halmet, can also be used for make law enfrocement official and Security Personnel's protective clothes such as the protective gear of protection people's neck and four limbs such as public security police.

The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be bulletproof anti-puncturing material structure schematic diagram, described bulletproof anti-puncturing material comprises internal layer and skin, is provided with shear thickening fluid layer 2 between internal layer and the skin, and internal layer and outer field edge are bonded together by adhesive 1.Internal layer is followed successively by the first nonwoven 3 and the second nonwoven 4 from inside to outside, skin is followed successively by the first nonwoven 3 and the second nonwoven 4 from inside to outside, one-way fiber close-packed arrays arranged side by side in every layer of nonwoven, the fiber direction of the first nonwoven 3 is 0 ° of direction, the fiber direction of the second nonwoven 4 is 90 ° of directions, and the angle between the fiber direction of the first nonwoven 3 and the second nonwoven 4 is 90 °.
Described shear thickening fluid for particle size be the nanometer grade silica particle of 10～50nm to be dispersed in molecular weight through ultrasonication be the non newtonian type liquid that obtains in 200 the polyethylene glycol, the mass fraction of nanometer grade silica particle is 50%.The nonwoven of described skin and internal layer is made by high-strength high-modulus polyethylene fiber.Described internal layer and the outer edge employed adhesive that bonds is polyethylene glue.
During making, covering the first nonwoven 3 in the inboard of the second nonwoven 4 forms outer, apply shear thickening fluid 2 at outer inboard mid portion, edge applies adhesive 1, cover successively again the second nonwoven 4 and the first nonwoven 3 formation internal layers thereon, dull and stereotyped compacting curing adhesive, so that shear thickening fluid is sealed in the nonwoven, the first nonwoven 3 and the second nonwoven 4 outer and internal layer also bond by the adhesive 1 that is penetrated into therebetween.
