Example 5, the feature of body protecting coat of the present invention are to possess two kinds of structures of this example 1 and example 4.
Example 6, body protecting coat of the present invention is characterized in that putting down in writing in one of them of example 1-5, than the part that the aforementioned first protection material 1 is more pressed close to the health inboard, is to adopt the made vest of aromatic polyamide fibers, as shown in Figure 1.
Below for the example further explanation again of the invention described above.
The tension force of aromatic polyamide fibers is that 20g/denier is preferable, and that generally more often be used is 20-30g/denier.Aromatic amides comprises (aromatic decarbonic acld, aromaticdiamine, aromatic aminoic acid) or the like, the representational high-tenacity fiber (aramid fiber) that is of aromatic polyamides (whole aromatic amide) fibrous material.
Wherein fibrous material is meant and weaves cotton cloth and fiber such as adhesive-bonded fabric constitutes.
Described particle size is meant the size of averaged particles in aforementioned this example 1-6.
1 li of example, the hard inorganic particles of this second protection material 2 is to adopt carborundum (SiC), and the magnitude range of its particle is between 400-500 μ m, and the fixed amount of particle is 400-700g/m
2Between, generally more welcome is to adopt 550-670g/m
2Between.
Also have, 3 li of examples, aspect stacking, with respect to one piece one piece all with the rectangular direction of protection face (direction that cutter tool thorn is come), adopt the mode that can move individually to overlap.
1 li of example, among the combination of the particle of the first protection material 1 that is adopted and the particle of the second protection material 2, the particle of having set the second protection material 2 is bigger than the particle of the first protection material 1, add the above-mentioned setting of particle size in each above-mentioned scope of respectively protecting material, cutting of can improving not only that the cutter tool caused cut and the protection function of bur, also can keep good mobility and dressing.Because the bigger second protection material 2 of particle cutting when cutting, can be conflicted earlier to hard inanimate matter particle for cutter tools such as kitchen knives in the outside, the aromatic amide fiber material has suppressed the cutter tool and has directly touched health.
The experimental result of being carried out, the size of particle according to the present invention in the scope of 400-500 μ m, blade to cut the damage meeting of cutting the fiber that causes lower.
In addition, if particle is greatly to the scope that surpasses the second protection material, 2 particle sizes, and area is excessive between the crack between the particle, and when being subjected to bur, the situation in interparticle slit is passed at the tip that can produce knife.Also have, if exceed above-mentioned scope, too when big, the contact area of particle and fibrous material diminishes particle, and particle set intensity step-down is cut for cutting of blade, want to bring into play pure defense, and be very difficult.
With the second protection material 2 relatively, the particle that this first protection material 1 is contained is less, but constant is, and is identical with the second protection material 2, all is set in order to prevent that blade from thrusting.Because of the magnitude range of particle is set between the 70-150 μ m, bur for sharp keen cutter tool demonstrates bigger drag, this is because particle is less, the tip that must not worry blade connects interparticle slit, add because of the little relation of particle, the flexibility of the first protection material 1 is higher, when the blade that connects the second protection material 2 lunges the first protection material 1,1 deformable of the first protection material plays the blade bag, so, the time that bur spent is elongated, adds that the distortion territory of the vest of accepting bur power becomes big, and measurable thus its can prevent that the conflict power of bur is transformed into the strength that runs through the first protection matter material 1.If this first protection material 1 is can configurable number piece, and under the overlapping mode that can move of one piece of one piece of difference, and its effect that prevents to run through function will be higher.
In addition, the first protection material 1 has more flexibility and convenient action property compared with the second protection material 2, even the first protection material 1 disposes many pieces, also can not damage the dressing and the mobility of its body protection utensil.
Cut protection function height for cutting of blade, and the second protection material 2 of the size of particle between 400-500 μ m is disposed at by health outside A, protection function height for bur, and the first protection material 1 of particle size between 70-150 μ m is disposed at by the inboard B of health, so body protecting coat design, can provide light and mobility is high, add to sharp keen blades such as kitchen knife or cold chisel to have pure protection function.
2 li of examples, because the size of the first protection material, 1 particle is to use the interior carborundum in above-mentioned scope, silica not only can be guaranteed its flexibility, also can use piece number of minimum, can possess the protective that sharp keen blade is had height.
3 li of examples,, use the particle in above-mentioned scope can guarantee that also body protecting coat possesses flexibility and mobility to a certain degree, and can highly keep aforesaid anti-cutter performance because the lamination number of the second protection material 2 is 1-3 piece.In addition, stacking piece of number scope setting the first protection material 1 is at 3-20 piece, the time that the aforementioned bur first protection material 1 is spent is elongated, adds the effect that increases the amplitude of deformation of accepting bur power vest, and the tip breakthrough second protection material 2 that can suppress blade arrives at health.
About example 4, having possessed the first protection material 1 becomes orthogonal to arrange the fiber alignment cloth 4 that accumulation forms with the polyethylene of super high molecular weight, fiber alignment cloth 4 to the first protection materials 1 will more close bodyside, when sharp-pointed blade bur to the first protects material 1, the existence of fiber alignment cloth 4 not only can suppress blade and lunge health, fiber alignment cloth 4 also has the function of bolster, can suppress blade and run through the first protection material 1.Therefore, can not increase sustainable again its mobility of maintenance of too many weight, can guarantee pure anti-blade function.
In addition, the body protection material that related example is 4 li, if the words that firearms are injected, because the polyethylene of super high molecular weight is to belong to low melting point, temperature when bullet interts makes the polyethylene dissolving of super high molecular weight, and the polyethylene that is dissolved around bullet can encase bullet, and the part of fiber alignment cloth 4 just may be blocked bullet, not only can keep anti-blade performance, also can improve the ballistic performance of body protecting coat.
The body protecting coat of example 5 is to have possessed the structure of example 4 with example 1, and the body protecting coat that possesses above-mentioned two side's invention advantages can be provided.
About example 6, the place than the first protection material, 1 more close bodyside has disposed by the made vest of aromatic amide fiber, therefore, even sharp keen point of a knife has pierced through the first protection material 1 a bit,, also can suppress the injury that point of a knife brings health having under the high-intensity vest defence.In addition, such a vest also can be regarded the bolster layer of the first protection material 1 as, can suppress blade and run through the first protection material 1.
Result of use of the present invention below is described.
The first protection material 1 is the aromatic amide fiber that is stained with the hard inorganic particles, so-called hard inorganic particles can adopt the pottery (ceramics) of carborundum, silica (silica), acidifying aluminium, charing boron, garnet (garnet) or the like to be the particle of principal component.For example: with optimal example, carborundum and silica etc.
Because the existence of hard inorganic particles, make the fragment that bullet or explosion thing are produced, or sharp keen blade or the like distortion or wearing and tearing, can reduce the penetrating force of bullet or blade, also have to absorb and disperse because of particle fragmentation, or the impact energy that comes off and produced.In addition, the particle size of the first protection material 1 is related to anti-cutter function and flexibility, and the size of particle is good between 70-150 μ m, and is better between the 90-120 μ m, if optimum between the 95-105 μ m.
Because if particle not only weighs excessive, and difficult crooked.Not only the property adorned is low, and the surface that is difficult in high-tenacity fiber has no ground, space and evenly coat particle, when the blade bur, because of the slit between particle and the particle, can produce the tendency that blade is run through easily.On the contrary, if particle is too small, the effect that absorbs impact energy reduces, and the blade that makes pierces through easily.
The fixed amount of particle, meeting changes to some extent because of weight that vest is allowed or the like, and, the hard inorganic particles is if adopt carborundum particle and so on, and the scope of its particle is at 150-200 μ m, and the scope that is set in 160-180 μ m is interior for good.In addition, the knoop hardness of the first hard inorganic particles that adopted of protection material 1 is 500kgf/mm
2More than be good.
Make the method that contains hard inorganic particles such as carborundum particle in the aromatic amide fiber, for example: the mode of utilizing coating, coat acrylic resin (acrylic resin) at Fypro, phenolic resins (phenolic resin), epoxy resin (epoxy resin), urthan resin, silicones (silicon resin) or the like solid, after single or double such as high-tenacity fiber form following layer, coat the silicon particle; Adding necessary drying processing after static is smeared promptly can be made into.
In addition, the aforesaid particle of infiltration is fixed it in the inside of aromatic amide fiber, and it is also good to make aromatic amide fiber contain the method for particle.
Also have,, also can produce the first protection material 1 with good anchorage if utilize the aqueous acrylic acid series solid.
Constitute the hard inorganic particles of the second protection material 2, can adopt the ceramic-like identical with the first protection material 1 is the particle of principal component, and for example: suitable is carborundum particle and silica.
The knoop of the second protection material, 2 employed hard inorganic particles, hardness is also identical with the first protection material 1,500kgf/mm
2More than, and preferably at 800kgf/mm
2For good.
The size of hard inorganic particles is cut the function that prevents of cutting in order to improve, and is good in the scope of 400-500 μ m.
Will be on aromatic amide fiber contains the method for hard inorganic particles, can use the above-mentioned general normal method that is used, as this protection material that in aromatic amide fiber, contains the hard inorganic particles, for example: the trade mark louvre stone that Teijin Ltd is made, this louvre stone are a kind of products that is stained with carborundum particle at high-tenacity fiber.
