preparation example Construction

[0024] The embodiment of the invention discloses a method for preparing a bullet-proof and stab-proof suit, including:

[0025] a) Spread and preheat the UHMWPE fiber uniformly;

[0026] b) Coating adhesive on the preheated ultra-high molecular weight polyethylene fiber and drying to obtain an areal density of 135g / cm 2 Single-layer non-weft fabric;

[0027] c) Take 18 layers of the single-layer non-weft fabrics obtained in step b to superimpose each other, the fibers in the adjacent non-weft fabrics are arranged at 0° / 20°, and the above-mentioned 18-layer non-weft fabrics are hot-compressed and composited with a layer of titanium alloy sheet Get the first composite layer;

[0028] d) Repeat step c to obtain the second composite layer;

[0029] e) The first composite layer, the titanium alloy layer and the second composite layer are superimposed to produce bulletproof and stab-resistant clothing. The first composite layer forms the outer layer, the titanium alloy sheet forms the middle...

Embodiment 1

[0050] 1. Place the 400-denier RYX90 ultra-high molecular weight polyethylene fiber produced by Ningbo Rongyi Chemical Fiber Technology Co., Ltd. on the creel. The spindles on the creel are assembled into bundles after passing through the bunching frame, and then enter the static elimination device after passing through the static electricity generating device. , Eliminate static electricity, and then preheat the uniformly spread UHMWPE fiber at a temperature of 50°C through a heating tunnel.

[0051] 2. Lead the preheated fiber into the gluing device and gluing through the gluing roller. The adhesive in the gluing roller includes: 15wt% epoxy resin, 8wt% neoprene rubber, 4wt% polystyrene-butadiene Diblock copolymer, 1wt% DOA and the balance of No. 120 solvent naphtha (2,3-butanedione), the surface density is 135g / cm 2 The content of adhesive in the weftless fabric is 35wt%.

[0052] 3. Take 18 layers of non-weft fabrics made in step 2 to superimpose each other, the fibers in adjac...

Abstract

The invention provides bullet-proof and stab-resistant clothes and a preparation method thereof. The bullet-proof and stab-resistant clothes sequentially comprises a first composite layer, a middle layer and a second composite layer from outside to inside, wherein the middle layer is a layer of titanium alloy sheet; both the first composite layer and the second composite layer sequentially comprise 18 layers of laid fabric with surface density of 135g / cm<2> and 1 layer of titanium alloy sheet from outside to inside; and fibers in the adjacent laid fabric layers are arranged in 0 to 20 degrees. The first composite layer and the second composite layer in the bullet-proof and stab-resistant clothes have higher cutting resistance and impact resistance, and the titanium alloy sheet of the inner layer is used for further improving the bullet-proof performance, so that the bullet-proof and stab-resistant clothes formed after the first composite layer, the middle titanium alloy sheet and the second composite layer are compounded are enough to resist attack of multiple times. Proved by test, the bullet-proof and stab-resistant clothes have excellent bullet-proof and stab-resistant comprehensive performance, accord with the standards of police bullet-proof clothes and stab-resistant clothes, are light in weight, and do not hinder the action of a wearer.

Description

Technical field [0001] The invention relates to the field of safety protection, in particular to a bulletproof and stab-proof clothing and a preparation method thereof. Background technique [0002] Security personnel face many critical situations during their duties, such as being attacked by bullets or stabbed by daggers. In order to ensure the safety of security staff in the struggle with criminals, providing security staff with bullet-proof and stab-resistant clothing to resist foreign invasion is of great significance to maintaining social public order. [0003] There are many kinds of stab-proof clothing or bullet-proof clothing. For example, the Chinese patent application No. 97108879.9 discloses a composite body armor. The basic bullet-proof material of the body armor includes at least Tuvalon, Dyneema, air bubble plastic layer and Polyethylene board. Although this kind of bulletproof material has a certain bulletproof effect, its puncture resistance is weak, and it is di...
