Preparation method of stab-resistant cut-resistant flexible material

Abstract

The invention relates to a preparation method of a stab-resistant cut-resistant flexible material. The preparation method comprises the following steps: choosing base cloth, coating the surface of thebase cloth with a glue, then adhering one or two of an organic polymer material and an inorganic particle, obtaining a composite, and thermally pressing the composite, thereby obtaining the stab-resistant cut-resistant flexible material. The preparation method is simple, the cost is low, and the prepared stab-resistant cut-resistant flexible material is light in weight and high in flexibility, and has excellent stab-resistant cut-resistant performances.

Description

technical field [0001] The invention belongs to the field of preparation of human body protection materials, and in particular relates to a preparation method of a stab-proof and cut-proof flexible material. Background technique [0002] With the rapid development of modern society, people are increasingly aware of the importance of safety. With the increase of violent and terrorist attacks, the demand for stab-proof clothing for personal protection is also increasing; Cut fabrics, so that it meets the requirements of anti-stab and anti-cut, while taking into account the functions of light weight, flexibility and easy production. [0003] At present, although many researchers have developed special protective products for stab and anti-cut protection, there are generally disadvantages in that the products are thick, not flexible and soft enough, and the price is relatively high. Patent WO9603277 uses a layer of plasma coating sprayed on the surface of the fabric. Although ...

Problems solved by technology

[0003] At present, although many researchers have developed special protective equipment for anti-stab and anti-cut protection, there are generally disadvantages of thicker products, insufficient flexibility and softness, and higher prices.

Patent WO9603277 uses a layer of plasma coating sprayed on the surface of the fabric. Although the dense plasma layer can play a better protective role, the plasma spraying process with high cost, long production time and complicated process are all As a result, this product cannot be mass-produced

Patent CN103791778A adopts large particles of epoxy resin bonded on the base cloth to achieve the anti-stab effect. The gaps between the particles can have better air permeability, but due to the large gaps between the particles, the anti-stab effect exists. Many weak links make the anti-stab effect unsatisfactory

The cut-resistant fabric prepared in the patent US7127879B2 is woven by twisting the fibers. Although the fibers are closely combined to achieve a cut-resistant effect, due to the tighter fibers and more layers, the cut-resistant fabric is The air permeability is poor, and as the frequency of use increases, the fibers are easy to be worn, which will cause the gradual reduction of the anti-cut effect

In the patent CN206182432U, the primer and re-glue process is adopted, and the rigid particles are fixed on the surface of the aramid fabric by using sand planting equipment. The resulting product has certain anti-stab and anti-cut properties, but the process is more complicated, and the cost of raw materials is higher, and With continuous friction during use, the surface particles will fall off, resulting in a gradual decline in the anti-cut and anti-stab effect
