Problems solved by technology

[0004] At present, traditional bulletproof shield products are mostly made of PE materials, and bulletproof shield products are prepared by hot pressing process, while aramid bulletproof shield products are mostly made of special fibers, which are woven into aramid woven fabrics, pre-impregnated, and hot-pressed. , but the bulletproof shield products made of this fiber are generally expensive, and the current market price is expensive
As for PE bulletproof shield products, their products have defects in temperature resistance, which limits their application fields to a certain extent.

Embodiment 1

[0018] First, weigh 1000g of acrylate adhesive aqueous solution and 100g of polyurethane adhesive emulsion, wherein the solid content of acrylate adhesive aqueous solution is 50%, and the solid content of ethylene-vinyl acetate adhesive emulsion is 50%. After mixing evenly, weigh 110g of Sanya Ethylenediamine, fully mix the glue solution for later use.

[0019] The aramid fiber is wound in parallel on the winding machine, and then the fiber is immersed in the above glue solution, and the yarn is spread by a specific spinning equipment. The adhesive used in this example is the above-mentioned modified adhesive. After dipping, spread the glue evenly with a squeegee, and dry it under an electric resistance wire at 80°C. After it is completely dry, rotate the cloth sample at 90°C, The method is to carry out orthogonal compounding of the fiber filaments and the sample fiber filaments, and obtain two layers of interlaced fabric samples. The resulting product structure is correspond...

Embodiment 2

[0022] Change the polyurethane adhesive emulsion in Example 1 to 10g, and all the other conditions are the same as in Example 1. Adopt Type 54 7.62mm pistol, Type 51 7.62 pistol bullet (lead core), test by GA423-2003 "Bulletproof Shield", the results are shown in Table 1.

Embodiment 3

[0024] In Example 1, 11 g of triethylenediamine was used, and the rest of the conditions were the same as in Example 1. Adopt Type 54 7.62mm pistol, Type 51 7.62 pistol bullet (lead core), test by GA423-2003 "Bulletproof Shield", the results are shown in Table 1.

Abstract

The invention provides an aramid fiber bulletproof shield manufacturing method and relates to the field of individual protection. In the aramid fiber bulletproof shield manufacturing, an aramid fiber non-weft fabric, the manufacturing method, a bulletproof shield manufacturing process and the like are adopted. Aramid fiber are subjected to fiber expanding, sizing and drying and then directly pressed to manufacture a bulletproof shield. A target practice test proves that the bulletproof shield manufactured by adopting the method is excellent in performance, high in safety margin and light in weight and can obviously improve the fighting efficiency of fighters.

Description

Technical field: [0001] The invention relates to a method for preparing an aramid bulletproof shield, and furthermore, relates to a bulletproof product applicable to the field of personal protection. Background technique: [0002] Bulletproof shield products are indispensable life protection equipment for public security and armed police personnel, and play a key role in anti-terrorism, while bulletproof shield products made of polymer fiber reinforcement have excellent physical, mechanical and chemical properties, and have better Excellent kinetic energy absorption and no "secondary damage capability". The missile body does not bounce, thereby reducing unnecessary casualties. High-performance fiber bulletproof shield products have the advantages of good bulletproof performance, small specific gravity (compared with pure steel), high temperature resistance, and no bouncing of projectiles. They are widely used in military engineering, personal protection, and armed police eq...
