Waste fiber-fabric-inorganic particle four-layer casting composite stab-resistant sheet, preparation method and applications thereof

Abstract

The invention relates to a waste fiber-fabric-inorganic particle four-layer casting composite stab-resistant sheet, a preparation method and applications thereof, wherein an inorganic particle-waste fiber cut section-fabric mixed and spaced four-layer structure is subjected to melting die-casting to form the composite stab-resistant sheet having a five-layer structure of a compact collision barrier layer, a gradient stacking layer, a fiber melt layer, a high-density stacking layer and a fabric melt layer. The preparation method comprises: mixing inorganic particles and fiber cut sections, paving, placing a fabric sheet, spreading inorganic particles on the fabric sheet, and covering with a fabric sheet, wherein the melting point of the fiber cut section is lower than the melting point of the fabric sheet, such that the fiber cut sections are molten in advance to settle the inorganic particles so as to obtain a gradient structure; and pressing the inorganic particles on the upper layerinto the fabric melt to form the composite stab-resistant sheet having the five-layer structure. According to the present invention, the prepared product has the high-efficiency collision barrier layer and the tough anti-brittle layer, and can be used for the individual protection dressing puncture-proof base materials for terrorism and riot prevention, fire protection, explosion prevention, earthquake search and rescue and national defense military.

Description

technical field [0001] The invention relates to individual anti-stab and anti-ballistic clothing materials, belonging to the field of functional technical textiles, in particular to a flexible, light-weight, high-efficiency resin composite sheet for anti-stab, cut and chop clothing and its preparation technology. Background technique [0002] Specialized protective equipment is required for anti-terrorism, anti-riot, firefighting, mutation accidents and other rescue and escape in peacetime, as well as in war or armed operations. The basic requirements of these equipment are: high-efficiency protective function and the requirement of light weight and softness without barriers to movement; and the latter is becoming more and more important and becoming more and more lightweight and soft. The control of guns in our country is relatively strict. Although there are controls on knives, they are easier to obtain and carry with you. Therefore, clothing in anti-terrorism and riot co...

Problems solved by technology

For example, according to various bionic principles, stab-proof materials are obtained. A kind of scale spliced ​​stab-resistant clothing based on hollow micro-eggshells (patent publication number: CN108095222A) draws on the overlapping arrangement of animal scales, according to the upper and lower layers. Arrangement layout, all stab-proof substrates made of plastic materials are arranged horizontally, and there are multiple hollow semi-ellipsoid shells arranged side by side and staggered on the stab-proof body, which can reduce the weight of the stab-proof material, but the stab-proof effect Affected by uneven overlapping; the scale-type stab-proof chip and the stab-proof equipment made of it (patent publication number: CN105403106A) are based on the principle of bionics to design the structure of the stab-proof chip by referring to the scales of crocodiles, including "pyramids" and cross-sections It is a fan-shaped columnar member, which can well disperse the puncture of sharp tools such as knives, and the cutting effect is easy to cause accumulation and puncture; the application and preparation method of nanotube aggregates in carbon nanotube impact-resistant materials (patent publication number: WO2017128944( A1)) The hollow structure of carbon nanotubes is used to absorb a large amount of impact energy. The carbon nanotubes are macroscopically ordered and microscopically disordered, and strive to achieve the best anti-stab and explosion-proof effect, but the scale is too small, the material stiffness is insufficient, and the anti-stab The performance increase is small but the cost is increased; a stab-resistant clothing based on carbon fiber board splicing blocks (patent publication number: CN106858769A) adopts a plurality of carbon fiber boards and a stab-resistant sheet processed by CNC, and is sandwiched with a metal sheet, which is stitched and sealed by a machine The anti-stab material has excellent anti-stab performance but is too heavy and too hard, suitable for mosaic or discontinuous sheets

[0008] To sum up, some existing hard or soft anti-stab materials still generally have the defects of uniform structure, bulky, rigid and single damping.
