preparation example Construction

[0023] The embodiment of the invention discloses a method for preparing a bullet-proof and stab-proof clothing, comprising:

[0024] a), uniformly spreading and preheating ultra-high molecular weight polyethylene fibers;

[0025] b), on the ultra-high molecular weight polyethylene fiber after preheating, coat adhesive and dry, and the prepared area density is 135g / m 2 single-layer non-weft fabric;

[0026] c), taking 36 layers of the above-mentioned single-layer non-weft cloths superimposed on each other, and the fibers in the adjacent non-weft cloths are arranged at 0° / 10°, and the above-mentioned 36 layers of non-weft cloths and 1 layer of titanium alloy are hot-pressed and composited to obtain a composite layer;

[0027] d), the composite layer is superimposed with 2 layers of titanium alloy sheets, the composite layer forms the outer layer, the titanium alloy sheet adjacent to the composite layer forms the middle layer, and another layer of titanium alloy sheet forms the ...

Embodiment 1

[0049] 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.

[0050] 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%.

[0051] 3. Take 36 layers of non-weft f...

Abstract

The invention provides a bulletproof and stab-resistant armor and a preparation method thereof. The bulletproof and stab-resistant armor sequentially comprises a composite layer, a middle titanium alloy sheet and an inner layer titanium alloy sheet from outside to inside, wherein the composite layer comprises 36 layers of non-woven clothes with the surface density of 135 g / cm<2> and one layer of the titanium alloy sheet from the outside to the inside; and the adjacent layers of the non-woven clothes are arrayed in the angle of 0 degree / 10 degrees. The composite layer in the bulletproof and stab-resistant armor provided by the invention has cutting resistance and impact resistance; the middle titanium alloy sheet and the inner layer titanium alloy sheet are used for further improving the bulletproof performance, so as to resist a plurality of attacks. The test proves that the bulletproof and stab-resistant comprehensive performance of the bulletproof and stab-resistant armor provided by the invention is higher and accords with the standards of bulletproof armors and stab-resistant armors for polices; and the weight of the bulletproof and stab-resistant armor provided by the invention is lighter so that the actions of people dressing the armors are not impeded.

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...
