Example Embodiment

[0017] Example 1

[0018] Firstly, weigh 1000g of acrylate adhesive aqueous solution and 100g of polyurethane adhesive emulsion. The solid content of the acrylate adhesive aqueous solution is 50%, and the solid content of the ethylene-vinyl acetate adhesive emulsion is 50%. After the mixture is uniform, weigh 110g Sanya respectively. Ethyl diamine, mix the glue thoroughly for use.

[0019] The aramid fiber is wound in parallel on a winder, and then the fiber is immersed in the above-mentioned glue solution, and the fiber is spread through a special spinning device. The adhesive used in this embodiment is the above-mentioned modified adhesive. After dipping, use a squeegee to spread the glue evenly, and dry it under an electric resistance wire at 80°C. After it is completely dried, rotate the cloth sample at 90°C and use the same In the method, the fiber filaments and the cloth-like fiber filaments are combined orthogonally to obtain a two-layer interlaced cloth pattern. The resul...

Example Embodiment

[0021] Example 2

[0022] The polyurethane adhesive emulsion in Example 1 was changed to 10 g, and the other conditions were the same as in Example 1. Use 54 type 7.62mm pistol, 51 type 7.62 pistol bullet (lead core), according to GA423-2003 "Bulletproof Shield" test, the results are shown in Table 1.

Example Embodiment

[0023] Example 3

[0024] In Example 1, 11 g of triethylenediamine was used, and other conditions were the same as in Example 1. Use 54 type 7.62mm pistol, 51 type 7.62 pistol bullet (lead core), according to GA423-2003 "Bulletproof Shield" test, 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...
