Abstract

The invention discloses a light-weight high-strength anti-puncture bulletproof garment and a manufacturing method thereof. An anti-puncture protection material is developed by aiming at people who need to make contact with sharp materials. According to the method, analysis is carried out according to a sharp object penetration process theory, high polymer materials with different properties are adopted, through the lamination of four layers different weaving structural materials and the addition of thermoplastic resin, then treatment and hot pressing are carried out matching with a prepared shear thickening liquid, so that the puncturing energy is dissipated in a large amount, and the protection effect is achieved. The prepared flexible anti-puncture material is soft in texture, the comfort level is good and the anti-puncture performance is good, the damage of sharp devices such toxic needles, daggers and cutting edges can be effectively prevented, the bulletproof garment is suitable for relative industry personnel such as grassroots level public security officers, anti-drug police and security personnel, and more safety guarantee is provided for the above people.

Description

technical field [0001] The invention belongs to the field of stab-proof materials, and relates to a light-weight, high-strength stab-proof bulletproof clothing and a manufacturing method thereof, in particular to a resin / plain weaving hot-press molding process and a preparation method of a shear-thickening liquid / aramid fiber composite material. Background technique [0002] The protective equipment used by the police in our country is the body armor uniformly equipped by the country. Although the bulletproof effect is very good, the body armor is heavy and inconvenient to move after wearing. It is not practical for grassroots police. And they face more injuries from sharp instruments such as poisonous needles, daggers and blades. Lightweight, soft, perspiration-wicking and high-strength stab-proof clothing is more suitable for grassroots police, anti-drug police and security personnel. The patent CN105559220 proposes to use ultra-high molecular weight polyethylene as a raw...
