Abstract
The utility model discloses the flexible shellproof sheet of preventing stinging of scheme will strengthen thermoplastic material through the shooting technique and permeate and constitute dual protective material layer after the base cloth in situ portion, set up some flexible clearance structural design between the symmetry and make on the protective material layer the utility model discloses a shellproofly preventing stinging the sheet and comparing with the market existing product, when protecting the same rank, weight is lighter, and gentle softness is better, and the dress has more the travelling comfort, has improved operation personnel's flexibility.
Description
Technical field
The utility model is related to a kind of bulletproof anti-puncturing material and in particular to a kind of anti-stab sheet material of flexible ballistic-resistant, is applied to people
Body life security protects technical field of composite materials.
Background technology
Existing double anti-material (shellproof, anti-stab) typically adopts high-strength polyethylene laminated cloth or Aramid No-Woven Cloth and metal material
The mode that material (aluminium alloy, titanium alloy etc.) overlaps, also adopts high-strength polyethylene or aramid fiber woven face to adopt resin to coat
Mode.Above scheme has as a drawback that：(1) metal material application scenario limited it is easy to be detected, in addition material
Harder, not soft, also heavier.(2) high-strength polyethylene or Aramid No-Woven Cloth adopt water-borne polyurethane bond bonding, only 5 years
Shelf-life, cost is also very high, and in addition this laminated cloth material cost is high.(3) resistance to elevated temperatures is poor, under more than 80 ° performances are notable
Fall.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides one kind shellproof and can prevent
Thorn, and make clothes comfortable and easy to wear, disguised strong it is also possible to manufacture the civilian products such as armlet, Anti-thorn gloves, cut resistant suitcase
Product, disclosure satisfy that the anti-stab sheet material of flexible ballistic-resistant of the needs of military domain and civil area.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of anti-stab sheet material of flexible ballistic-resistant, including base
Layer of cloth, is molded with enhancing thermoplastic respectively in the both sides of described base cloth layer, and described enhancing thermoplastic hot melt penetrates into
Two sides layer of protective material is constituted behind base cloth layer inside；In described layer of protective material symmetrical between offer multiple flexibility gaps knot
Structure.
Further improved as the utility model, the interstice coverage of described flexibility interstitial structure is 0.1-3mm.
Further improved as the utility model, described flexibility interstitial structure is to have the V-shaped groove structure at inclination angle or be
Square groove structure.
Further improved as the utility model, described layer of protective material thickness is 0.3-5mm.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages：
The anti-stab sheet material of flexible ballistic-resistant of the utility model scheme, penetrates into base by Shooting Technique by strengthening thermoplastic
Two sides layer of protective material is constituted behind layer of cloth inside, because in injection moulding process, protective materials is in HTHP vacuum environment, therefore
Injection protective layer structure out is closely knit, and bubble void content is few, and intensity is high, and barrier propterty improves, and its ballistic performance meets
GA141-2010《Police flak jackets》Standard；Anti-stab performance meets People's Republic of China's public safety industry newest standards
GA68-2008《Police stab-resistance body armor》Standard carries out puncturing test according to 24J energy, and result shows that stab-resistance body armor complies fully with standard
Every technical requirements of defined；In addition the flexible interstitial structure offering between symmetrical in layer of protective material designs and makes this practicality
, compared with existing products in markets, during protection same levels, weight is lighter for new bulletproof anti-puncturing sheet material, and pliability more preferably, is worn
More comfortableness, improves the flexible of combatant.
Brief description
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further：
Accompanying drawing 1 is the structural representation of the anti-stab sheet material of flexible ballistic-resistant of the present utility model；
Accompanying drawing 2 is another structural representation of the anti-stab sheet material of flexible ballistic-resistant of the present utility model；
In figure：1st, base cloth layer；2nd, layer of protective material；3rd, flexible interstitial structure.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of anti-stab sheet material of flexible ballistic-resistant described in the utility model, including base cloth layer 1, in the both sides of described base cloth layer 1
It is molded with enhancing thermoplastic respectively, described enhancing thermoplastic hot melt constitutes two sides after penetrating into base cloth layer 1 inside and prevents
Protective material layer 2；In described layer of protective material 2 symmetrical between offer multiple flexibility interstitial structures 3；Described flexibility interstitial structure
The minimum 0.1mm in gap, is 3mm to the maximum；Described flexibility interstitial structure is the V-shaped groove structure with inclination angle, as shown in Figure 1,
Or be square groove structure, as shown in Figure 2；Described layer of protective material 2 thickness range is 0.3-5mm.
Described enhancing thermoplastic includes reinforcing material and thermoplastic, and described thermoplastic accounts for layer of protective material
Quality proportion be 75%, the quality proportion that described reinforcing material accounts for layer of protective material be 25% so as to get sheet material pliable and tough
Degree reaches optimization so as to ballistic performance：Meet GA141-2010《Police flak jackets》Standard；Anti-stab performance：Meet GA68-
2008《Police stab-resistance body armor》Standard；
Base cloth layer selects carbon fiber, aramid fiber, the fabric that in glass fibre, one or more are made, and material grammes per square metre scope exists
100-500 gram/m, thickness range is 0.1-0.5mm.
Thermoplastic selects nylon66 fiber, nylon 6, Merlon, polypropylene, one or more of polyformaldehyde.
Reinforcing material selects short fiber reinforced material, such as carbon fiber, glass fibre, aramid fiber, basaltic one kind
Or it is several.
Flexible interstitial structure 3 can be realized by several techniques once：
1) hot pressing：First that hot pressing is upper, lower mould is obtained by way of machining, then installs on upper/lower die
Upper heater, hot pressing die is warmed on the fusing point of protective materials, then sets suitable pressure, in base fabric both sides
Thin plate on extrude certain gap, reach softness degree.In order to ensure the flexibility of material, the upper/lower die of hot pressing must
High degree of symmetry, the gap going out in the hot pressing of base fabric both sides must be in same level position.
(2) machining：By milling cutter, the laser or other modes symmetric position in base fabric both sides removes the thin of injection formed
The gap setting on plate, ensures not damaging base fabric simultaneously.
(3) chemical etching：Realized by way of chemical etching.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within the utility model rights protection scope it
Interior.
