“High-strength” fiber, as a term used in the current specification, is 11 g/denier or having a greater strength and a shrinkage of 200 g/denier or more. refers to fiber.

Figure 1 is a cross-sectional view of a leadproof material according to Example 1 of the present invention. depicts.

As shown in Figure 17, a bulletproof material 100 according to Example 1 of the present invention, It has a front face (FS) against which the bullets will strike and a rear face (BS) on the reverse side of the FS.

The bulletproof material (100) has multiple first fibrous layers (110) on the anterior face (FS) and the first a second fibrous layer 120 adjacent the fibrous layers 110.

A bulletproof material (100) is a material that meets the lightening requirements of a bulletproof vest. have mass per unit area, eg 3 to 6.8 kg/m2 per unit area contain a first fibrous layer (110) and a second fibrous layer (120) in an appropriate number of layers. is doing. In accordance with Example 1 of the present invention, the leadproof material (100) is 10 to 32- the ply first fibrous layer 110 and a one-ply second fibrous layer 120.

The first fibrous layers (110) on the anterior face (FS) have a strength of 11 g/denier or more and comprising a high-strength fiber web having a tensile coefficient of g/denier or more is doing. High-strength fiber, ultra-high molecular weight polyethylene (UHMWPE) fiber or aramid fiber.

In accordance with Example 1 of the present invention, the "high-strength" fiber web is used as warp and weft. It is an aramid woven fabric containing aramid fiber. Each woven fabric per unit area gaps may exist between woven fabrics and are therefore bulletproof performance may decrease. On the other hand, woven, mass per unit area, more than 500 g/m2 If it is carried out in a larger way, the production efficiency may decrease.

As aramid fiber is prone to moisture, its bulletproof performance will improve over time. may decrease. To address such a problem, the aramid weave of the first fibrous layers 110 water-repellent fabrics containing fluorocarbon, a cross-linking agent and a hardness-enhancing resin can be covered with one.

The fluorocarbon imparts water repellency to the first fibrous layers 110. As a fluorocarbon hydroxylated perfluoroalkylethyl acrylate copolymer can be used.

Meanwhile, a water-repellent component such as fluorocarbon, in harsh environments or long-term use it is then removed from a high-strength fiber network so that the high-strength The `properties of the fiber deteriorate and its bulletproof performance is quickly damaged by moisture. may decrease in the course of time. Accordingly, the difference between high-strength fiber and fluorocarbon water-repellent, also a cross-linking agent, other than fluorocarbon, to increase adhesion as an isocyanate-based compound, such as toluene diisocyanate or methylene diphenyl diisocyanate. can.

Additionally, in order to suppress back-face deformation of the bulletproof material 100, The water repellent may also contain a hardness-enhancing resin such as polyvinyl acetate.

Optionally, a water-repellent may also be used as an anti-foaming agent (eg. dipropylene glycol) and an emulsion stabilizer (eg malic acid). This In this case, water-repellent, from 05 to 10% by weight of fluorocarbon, from 05 to 10% by weight of hardness-enhancing resin, 05 to 5% by weight of cross-linking agent, 01 to 2% by weight of antifoaming agent, by weight Expect the desired water repellency when the fluorocarbon content is less than 0.5% by weight. it is difficult. When the fluorocarbon content is greater than 10% by weight, the water repellency is widely does not increase and the flexibility of the bulletproof material 100 may further decrease.

When the content of the hardness-enhancing resin is less than 0.5% by weight, it is bulletproof the back-face deformation characteristics of the material 100 are hardly ever improved.

When the content of the hardness-enhancing resin is greater than 10% by weight, it is bulletproof the flexibility of the material (100) is reduced and hence the bulletproof material (100) The feeling of wearing a bulletproof vest is greatly reduced. When the content of the cross-linking agent is less than 0.5% by weight, the desired water It is difficult to maintain its repulsiveness. The content of the cross-linking agent is less than S% by weight larger, the effects do not increase, but manufacturing costs increase.

In order to apply the water repellent to the high-strength fiber web, cushioning, coating, dipping, a method such as spraying, brushing or film-coating may be used. aga water repellent can be realized.

Optionally, the high-strength" fiber web of the first fibrous layers 110 is arranged in one direction. containing a large number of ultra-high molecular-weight polyethylene fibers and/or aramid fibers and a composition comprising a high-strength" fiber web, a polyurethane resin can be covered with Within each of the first fibrous layers (111, 112, and 113), high- strength fibers are oriented unidirectionally in a parallel fashion. first fibrous The high-strength fiber of layers 111, 112 and 113 is made of a polyurethane resin-containing are coated with the composition so that arrangements of high-strength fibers can be preserved. Composition on high-strength” fibers can be sprayed or applied as a film to high-strength fibers. strength fibers may be cross-folded to form an angle of approximately 90°. Cross-folded fibrous sheets 111 and 112 form a unidirectional fabric.

Optionally, unidirectional fabric, unidirectionally oriented multi-high-density polyethylene may consist of four fibrous layers containing fiber or aramid fiber. In this case, the four fibrous layer, where the angles of rotation between their high-strength” fibers will be 0°/90“70790°0 It can be cross-folded in the shape of

The second fibrous layer 120 on the back side BS of the bulletproof material 100 is made of carbon fiber. contains an ag. Carbon fiber mesh is a fabric containing carbon spun yarn as warp and weft. woven fabric. when the mass is less than 110 g/mz, gaps exist between the second fibrous layer 120 can be found, thus causing a decrease in lead-proof performance.

On the other hand, the second fibrous layer (120) will be greater than 480 g/m2 of mass per unit. When properly prepared, it does not prevent the bulletproof material (100) from being lightened. or lead to a decrease in the bulletproof performance (unit of the bulletproof material The number of first fibrous layers is reduced to adjust the mass per area to a favorable state. The physical impact from the bullets is applied to the front face (FS) of the bulletproof material (100). when, the front face (FS) of the bulletproof material 100 is partially deformed. This the deformation propagates to the back face BS of the bulletproof material 100, thus allowing A back face deformation greater than the allowable safe separation distance occurs. brings.
