preparation example Construction

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

[0025] a) Spread the UHMWPE fibers evenly and preheat them;

[0026] b) Coating the adhesive on the preheated UHMWPE fiber and drying it to obtain an areal density of 135g / m 2 single-layer non-weft fabric;

[0027] c) Take 18 layers of step b to make single-layer non-weft fabrics superimposed on each other, and the fibers in adjacent non-weft fabrics are arranged at 0° / 20°, and heat-press the above-mentioned 18 layers of non-weft fabrics and 1 layer of titanium alloy sheet, Obtain the first composite layer;

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

[0029] e) Superimpose the first composite layer, one titanium alloy layer and the second composite layer to obtain a bulletproof and stab-proof clothing, the first composite layer forms the outer layer, the titanium alloy sheet forms the middle layer, and the second The composi...

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 pass through the cluster frame and then gather into bundles. After passing through the static electricity generation device, they enter the static electricity elimination device. , Eliminate static electricity, and then preheat the uniformly spread ultra-high molecular weight polyethylene fibers at a temperature of 50°C through a heat tunnel.

[0051] 2. Lead the preheated fiber into the gluing device and apply glue through the rubber roller. The adhesive in the rubber roller includes: 15wt% epoxy resin, 8wt% neoprene rubber, 4wt% polystyrene-butadiene Diblock copolymer, 1wt% DOA and the balance of No. 120 mineral spirits (2,3-butanedione), the prepared areal density is 135g / m 2 The non-weft cloth, the content of adhesive in the non-weft cloth is 35wt%.

[0052] 3. Take 18 layers of non-weft f...

Embodiment 2

[0056] 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 pass through the cluster frame and then gather into bundles. After passing through the static electricity generation device, they enter the static electricity elimination device. , Eliminate static electricity, and then preheat the uniformly spread ultra-high molecular weight polyethylene fibers at a temperature of 45°C through a heat tunnel.

[0057] 2. Lead the preheated fiber into the gluing device and apply glue through the rubber roller. The adhesive in the rubber roller includes: 10wt% epoxy resin, 6wt% neoprene rubber, 5wt% polystyrene-polyisoprene Diene diblock copolymer, 0.6wt% DOA and the balance of No. 120 mineral spirits (2,3-butanedione), the prepared areal density is 135g / m 2 The non-weft cloth, the content of adhesive in the non-weft cloth is 38wt%.

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 bullet-proof and stab-proof clothing and a preparation method thereof. Background technique [0002] Security personnel have to face many critical situations during their duties, such as being attacked by bullets or stabbed with daggers. In order to ensure the life safety of security staff in the fight with criminals, it is of great significance to maintain social public order to provide security staff with bulletproof and stab-resistant clothing to resist external invasion. [0003] Existing multiple anti-stab clothing or bullet-proof clothing, disclose a kind of composite bullet-proof clothing as the Chinese patent that application number is 97108879.9, the basic bullet-proof material part of this bullet-proof clothing at least comprises tuvalon, dyneema, air bubble plastic layer and Polyethylene board. Although this kind of bulletproof material has a certain bulletproof ef...
