In general, the body armor that protects the human body from firearms is a self-protection tool that protects the human body from the threat of firearms of the enemy during police work or various security services, and includes a shell, ballistic plate, and bulletproof plate.

Such body armor has been actively developed in countries where the use of firearms is legalized, such as the United States, and in particular, it is manufactured in accordance with the testing standards for police body armor of the US Department of Justice Judicial Research Institute.

On the other hand, in the case of countries where the use of firearms is not legalized, such as the Republic of Korea, the development of a swordsman uniform to protect the body from weapons with sharp tips or blades such as knives and awls is further required. Such a swordsman suit includes a swordsman pad that prevents objects having a sharp tip or blade, such as a knife or awl, from penetrating through.

In addition, in addition to the police, maritime police, defense, and security services, the demand is increasing day by day as they are used in various work sites or industrial sites that may cause physical damage due to exposure to sharp objects.

As an example of the above-described anti-cancer pad or anti-prevention suit equipped with the same, Korean Patent Application Laid-Open No. 10-2004-0090764 (published on October 27, 2004) includes a cover, a buffer layer positioned below it, and an easy and a buffer layer positioned above it. In the anti-glare panel consisting of a metal plate that is integrally fixed and maintained by an adhesive layer between the buffer layers, the metal plate is integrally formed without a gap by overlapping and bonding a plurality of pieces of the same shape and size adjacent to each other. Disclosed is a bang prevention panel, characterized in that.

In addition, Korean Patent Laid-Open No. 10-2016-0109928 (published on September 21, 2016) includes a shoulder portion composed of an elastic band connecting one end of the front portion and the rear portion, and the front portion and the rear portion, and the front portion bordering the shoulder portion. A through hole configured to allow the human head to pass between the part and the rear part, and a fastening port composed of a Velcro band fixed to both sides of the other end of the front part or the rear part to fix both sides of the other end of the front part and the rear part, and A protective core is provided on the front and rear portions, and the protective core is formed with an aramid fiber layer having a density ratio of 360 to 560 g/m2 on at least one of the upper and lower surfaces of the metal mesh, and 160 to 360g/m2 on the upper and lower portions thereof. Disclosed is a control suit, characterized in that a coconut coir layer having a density ratio and an aramid fiber layer having a density ratio of 360 to 560 g/m 2 are stacked and then compressed.

However, in the case of the above-described conventional swordsman pad and the swordsman uniform equipped with the same, for example, when worn for a long time, as a metal plate having at least one layer or more must be included so that a weapon having a sharp tip or blade, such as a knife or awl, cannot penetrate. There was a problem in that fatigue was increased due to the weight of the metal plate.

As an example of a solution to this problem, Korean Patent Registration No. 10-1458996 (announced on November 7, 2014) has an aramid fabric layer in which a plurality of aramid fabrics laminated with an ionomer are laminated, and excellent in tensile strength. Aramid paper layers in which a plurality of aramid papers are stacked are composed of three or more layers alternately with each other, and the aramid paper layer is made of 20-70% by weight of para-aramid floc and 30-80% by weight of meta-aramid fibrid. Disclosed is a lightweight cloth for swordsman, characterized in that it is configured, and a protective clothing for swordsmanship using the same.

In addition, Korean Patent Laid-Open No. 10-2013-0016861 (published on February 19, 2013) includes a plurality of fabric laminates made of high-strength fibers selected from the group consisting of glass fibers, aramid fibers, and carbon fibers, and the Consists of including an epoxy resin impregnated in the fabric laminate, the epoxy resin contains 1 to 15 parts by weight of silicon nitride based on 100 parts by weight of the epoxy resin, the ratio of the fabric laminate to the epoxy resin is 1: It is 0.43 to 1, and a bulletproof and bulletproof plate, characterized in that a plate made of polycarbonate is adhesively laminated, is posted on one side of the bulletproof and bulletproof plate.

However, in the case of such a sword pad and a sword suit equipped with the same, for example, as it is based on an aramid fiber material, it has the advantage that it is lightweight and increases flexibility, but a simple layered aramid fiber material or a resin impregnated material based thereon There was a problem in that it was formed only in a structure, so that the sword fighting efficiency was lowered.

1. Korean Patent Publication No. 10-2004-0090764 (published on October 27, 2004) 2. Korean Patent Publication No. 10-2016-0109928 (published on September 21, 2016) 3. Korean Patent Registration No. 10-1458996 (announced on November 7, 2014) 4. Korean Patent Publication No. 10-2013-0016861 (published on February 19, 2013)

It is intended to provide a sword-proof pad and a sword-proof suit including the same, so that it is possible to significantly improve the sword-proof efficiency as it is light-weight and flexible, but it is a combination of multiple-stage stacking of sword-proof materials having different sword-proof characteristics.

In addition, it is not limited to the technical problems as described above, and it is obvious that another technical problem may be derived from the following description.

As shown in FIG. 1, the anti-sword pad 1 according to an embodiment of the disclosed subject matter is provided in the anti-sword suit 2, but is arranged around the chest and abdomen on both sides of the vest-shaped anti-surgery body 3 It serves to protect the body.

The anti-sword pad 1 according to an embodiment of the present disclosure includes a first pocket 4 each formed on a portion corresponding to the left and right chest of the user among the inner surfaces of the vest-shaped anti-sword uniform body 3, and In the inner surface of the body 3, a second pocket 5 is formed in each of the areas corresponding to the user's left and right abdomen, and a flap shape is formed on the inner surface of the room sword body 3 corresponding to the user's left and right sides. It is preferable that it is provided in the third pocket 6 which is attached and fixed by, for example, Velcro tape on the back side of the inner surface of the anti-sword control body 3.

In addition, it is preferable that the first pocket 4, the second pocket 5 and the third pocket 6 can be opened and closed by a known opening and closing means such as a zipper or velcro tape for the detachable interior of the anti-cancer pad 1 .

FIG. 2 is a structural diagram of a bang sword pad according to an embodiment of the disclosed content, and FIG. 3 is a detailed structural diagram of a bang sword repulsion force forming layer in the bang sword pad according to an embodiment of the disclosed content.

As shown in FIG. 2, the anti-tip pad 1 according to an embodiment of the disclosed subject matter is a tip blunting induction layer formed by laminating a plurality of tip abrasion sheets 11 coated with particles for tip abrasion on aramid fibers (10) And, the first unidirectional aramid sheet 21 and the aramid fibers stacked on the rear surface of the end blunting induction layer 10 and arranged in one direction and the aramid fibers are the fiber arrangement direction of the first unidirectional aramid sheet 21 The second unidirectional aramid fiber sheets 23 arranged in one direction in a state having an angular deviation in the range of 30 to 60 degrees are alternately stacked several times and formed of the anti-sword repulsive force forming layer 20 and the anti-sword repulsive force forming layer 20 It is laminated on the rear surface and includes a phenolic resin coated on the aramid fiber body and formed by the anti-sword repulsion support layer 30.

Here, the tip blunting induction layer 10 blunts the tip or blade of a sharp weapon, such as a knife or awl, through friction, so that the bang sword repulsion force of the bang sword repulsion force forming layer 20 to be described later may be increased. It plays a role of making.

The end blunting induction layer 10 is formed by laminating a plurality of aramid fibers, which are high-strength yarns, to aramid fibers woven through a weaving technology such as twill or plain weaving, and coated with particles for tip abrasion. do.

The aramid fiber is preferably a Kevlar signature made by Dupont, and the thickness and number of aramid yarns are preferably 40 numbers 3 sums to 60 numbers 2 sums for proper fabric density and yarn integration in the fabric.

In addition, since the density of the aramid fiber body forming the end wear sheet 11 must be large, it is preferable that a weaving technique such as plain weave or twill weaving is applied to the weaving of aramid yarn rather than a knitting weave capable of producing a relatively low density fabric.

In addition, the tip abrasion sheet 11 forming the tip blunting induction layer 10 includes a coating agent mixed with a binder after dispersing particles for tip abrasion consisting of at least one of alumina, titanium dioxide, and silicon carbide in a dispersant, and then coating the aramid fiber body. It is desirable to be formed.

At this time, the dispersant is preferably MA ^® dispersant from Master Additives Sdn Bhd of Malaysia, and the binder can be formed of an epoxy dilute solution obtained by diluting 5 to 10% by weight of an epoxy stock solution with 90 to 95% by weight of acetone. In addition, the coating of the tip abrasion particles is performed by dispersing the tip abrasion sheet 11 in a dispersant, immersing it in an immersion solution containing a coating agent mixed with a binder, and then drying it at, for example, 120°C for 10 minutes. Done. In addition, as for the immersion liquid, it is preferable that a softener such as a 5% sodium chloride aqueous solution, a particle dispersion for tip abrasion, and a binder are mixed in a ratio of, for example, 1:7:2.

In addition, the tip abrasion sheet 11 forming the tip blunting induction layer 10 may be formed by bonding a sheet body to which at least one tip abrasion particle of alumina, titanium dioxide, and silicon carbide is bonded and fixed to the front surface of the aramid fiber body. have.

The end blunting induction layer 10 is preferably formed by stacking 3 to 7 sheets, particularly 5 sheets of tip abrasion sheets overlapping each other.

A barrier repelling force forming layer 20 is stacked on the rear surface of the tip blunting induction layer 10 described above. The sword fighting repulsion forming layer 20 actually serves to provide a sword sword repulsive force so that the tip or blade of a sharp weapon such as a knife or awl cannot penetrate through.

The anti-surge repulsion forming layer 20 is arranged in one direction in a state in which the aramid fibers are arranged in one direction and a first unidirectional aramid sheet 21 and the aramid fibers have a certain angular deviation from the fiber arrangement direction of the first unidirectional aramid sheet 21 The second unidirectional aramid fiber sheets 23 are alternately laminated and formed several times.

The first unidirectional aramid sheet 21 and the second unidirectional aramid sheet 23 are, for example, unidirectional aramid fiber bundles made of, for example, unidrectional para-aramid, a thermoplastic resin material such as polyester, polyethylene or polyurethane. It has a structure that is fixedly arranged in a sheet form by

The fiber arrangement direction of the first unidirectional aramid sheet 21 and the second unidirectional aramid sheet 23 preferably has an angular deviation of 30 to 60 degrees, particularly 45 degrees.

It is preferable that the antimicrobial repulsion forming layer 20 is formed by alternately stacking the first unidirectional aramid sheet 21 and the second unidirectional aramid sheet 23 alternately 10 to 20 times, particularly 15 times.

On the rear surface of the above-described anti-sword repulsive force forming layer 20, the anti-sword repulsive force supporting layer 30 is stacked. The anti-sword repulsion support layer 30 corresponds to a kind of repulsive force supporting layer that supports the anti-sword repulsion force by the anti-sword repulsion force forming layer 20 from the rear.

This anti-bang repulsion support layer 30 is formed by coating a phenol resin on the aramid fiber body. Since the aramid fiber body for formation of the anti-barrier repulsion support layer 30 is the same as the aramid fiber body for the formation of the tip wear sheet 11 of the tip blunt induction layer 10, here, for the sake of simplicity of the specification, further overlapping descriptions are provided. I will omit it.

The anti-barrier repulsion support layer 30 is laminated to dry after attaching a resin film containing phenolic resin to one side of the aramid fiber, pressurizing it at high temperature and high pressure (for example, 60 to 120°C, 50 to 500 bar). ). The content of the resin film is preferably 10 to 20% by weight compared to the content of the aramid fiber for weight reduction.

The resin film containing a phenolic resin preferably includes 20 to 70% by weight of a phenolic resin and 20 to 70% by weight of a polyvinylbutyral (PVB) resin.

If the content of phenolic resin is less than 20% by weight, the hardenability is poor and the morphology stability may be poor, and if the content of phenolic resin exceeds 70% by weight, heat resistance and shape stability increase, but adhesion and moldability. This can fall.

If the content of the polyvinyl butyral resin is less than 20% by weight, the moldability may be poor and the adhesive strength may decrease. If the content of the polyvinyl butyral resin is more than 70% by weight, the processability and adhesion are improved, but heat resistance and The sword performance may be degraded.

In addition, the resin film may further include a polyurethane resin, and for example, may further include at least one plasticizer of alkylene, polyalkylene glycol, benzoate, aliphatic diol, alkylene polyol, and diester.

The above-described end blunting inducing layer 10, the barrier repelling force forming layer 20, and the barrier repelling force supporting layer 30 are integrally surrounded by the outer skin 40. The outer shell 40 corresponds to a cover that maintains a stacked state by simply integrating a sequentially layered tip blunting induction layer 10, a barrier repelling force forming layer 20, and a barrier repelling force supporting layer 30, and includes various aramid fibers. It can be formed from fabric.

In addition, a buffer layer 50 may be stacked on the rear of the anti-sword repellency support layer 30 described above. The buffer layer 50 is a synthetic resin such as polyethylene foam having a thickness of 4 to 6 mm to mitigate the impact generated when a sharp weapon such as a knife or an awl enters to minimize the impact on the user's body part. It can be formed into foam.

When the thickness of the buffer layer 50 is less than 4 mm, the buffering effect is insignificant, and when the thickness of the buffer layer 40 exceeds 6 mm, the thickness and volume of the anti-cancer pad 1 are excessively increased, which is not preferable.

As described above, the antimicrobial pad 1 according to an embodiment of the disclosed content is sequentially stacked to form the antimicrobial pad 1, the tip blunting inducing layer 10, the antimicrobial repulsion forming layer 20, and the antimicrobial repulsion As all of the support layers 30 are based on aramid fiber instead of a metal plate, the overall weight is light, so even if worn for a long time, the user's fatigue is reduced, and the user's free movement is possible due to the improved flexibility.

In addition, the sword pad 1 according to an embodiment of the disclosed content is such that the sharp tip or blade of the weapon is blunted by the tip blunt induction layer 10, and the weapon cannot penetrate through the sword repulsion force forming layer 20 As the sword repulsive force is generated, and the sword repulsive force of the sword repulsive force forming layer 20 is supported from the rear by the anti sword repulsive force support layer 30, the tip slowing induction layer 10 and the anti sword repulsive force forming layer 20 having different anti-sword properties. ) And the anti-sword repellency support layer 30 are sequentially stacked in multiple stages, so that the anti-sword efficiency can be significantly improved.

In addition, in the case of the anti-sword suit (2) including the anti-sword pad (1) according to an embodiment of the disclosed contents, a sequentially layered tip blunting induction layer (10), a anti-sword repulsive force forming layer (20), and a anti-sword repulsive force support layer (30) The included anti-cancer pad (1) is accommodated in the first pocket (4), the second pocket (5) and the third pocket (6) on the vest-shaped anti-prevention body (3) to surround the user's left and right chest and abdomen. As it is arranged, important parts of the body can be safely protected from weapons.
