Preparation process of a flexible bullet-proof and stab-proof structure

Abstract

The invention relates to a preparing technology for a flexible bullet-proof and piercing-proof structure. The preparing technology specifically comprises the following preparing steps that firstly, a protection composite particle material is prepared; secondly, base cloth is laid between two sets of injection molds of an injection molding machine, the protection composite particle material is arranged on the two sides of the base cloth in an injection molding manner through the injection molds at the same time, the protection composite particle material is subjected to hot melting, seeps into a base cloth layer and then is cured to form a two-face protection material layer, mold opening is conducted, after the base cloth of an injection molding part is downwards transmitted, the base cloth is tensioned, and then injection molding is conducted; and thirdly, a flexible gap is machined. The structure of the product prepared through the preparing technology has excellent bullet-proof and piercing-proof performance and also has improved flexibility performance. A thermoplastic material and an enhanced material composite material are arranged on the adopted base cloth in an injection molding manner, the thermoplastic material and the enhanced material composite material are subjected to hot melting, seep into the base cloth layer and then are cured to form the two-face protection material layer, gaps among particles of the thermoplastic material and the enhanced material composite material can be eliminated, and the structure is compact and has more excellent bullet-proof and piercing-proof performance; and in addition, the preparing technology is simple, and the production efficiency is high.

Description

technical field [0001] The invention relates to a preparation process, in particular to a preparation process of a flexible bulletproof and stab-proof structure, which is applied in the technical field of composite materials for human life safety protection. Background technique [0002] Body armor is a kind of equipment that can absorb and dissipate the energy of warheads, prevent penetration, reduce blunt trauma and effectively protect the protective parts of the human body. Stab-proof clothing is a kind of clothing that can effectively protect the human body from various angles and reduce the threat of stab wounds to the protective parts of the human body. They are protective equipment that public security officers and security personnel must wear when performing dangerous tasks to protect the main organs of public security officers and security personnel from damage caused by common offensive weapons such as bullets and daggers. [0003] At present, the international an...

Problems solved by technology

The above-mentioned technical solution has the following disadvantages: (1) metal materials have limited application occasions and are easily detected, and the material is relatively hard, not soft, and heavy; (2) high-strength polyethylene or aramid non-woven fabrics use water-based polyurethane glue Bonding has only a 5-year shelf life, and the cost is also high. In addition, the cost of this non-weft material is high; (3) The high temperature resistance is poor, and the performance drops significantly above 80 °C
