Abstract

The invention relates to a preparation process of a double-side formation grid anti-piercing material. The method comprises the following steps: tiling grid cloth on a working table and fixing four sides by using clamps; coating an adhesive on the surface of each macromolecular particle by using an automatic dispenser; after the adhesive is coated on the surface of each macromolecular particle, discretely adhering the particles to the grid cloth by using a manipulator according to designed pattern distribution; turning over the grid cloth and fixing to the working table, repeating the step, and curing the macromolecular particles on the surface of the grid cloth by using the manipulator to finally prepare the double-side formation grid anti-piercing material. The grid cloth with ultrahigh performance is compounded with the macromolecular particles, and the grid cloth has the effect of reinforcing ribs, so that the mechanical strength of the anti-piercing layer is greatly improved. The macromolecular particles and the grid cloth are tightly compounded and are distributed in the discrete state, so that the entire anti-piercing material as a certain gap, and good softness and air permeability of the prepared anti-piercing material are guaranteed.

Description

A kind of double-faced forming grid stab-resistant material and manufacturing process thereof
[technical field]
The present invention relates to a kind of functional protective materials and manufacturing process thereof, particularly relate to a kind of novel two-sided shaping grid stab-resistant material and manufacturing process thereof.
[background technology]
Along with socioeconomic development, public safety problem becomes more and more outstanding, and people more and more recognize the importance that inherently safe protects, and country also increases the supporting dynamics to safety protection field.In the last few years, stab-resistance body armor was progressively separated with ballistic protective clothing, and paid attention to by various countries researcher and go deep into research and development, stab-resistance body armor has become current popular research object.In September, 2009, the Ministry of Public Security of China assigns " public dress No. [2009] 705, wealth is about the notice assigning bulletproof stab-resistant clothes tactical and technical norms ", wishes the development work completing domestic bulletproof stab-resistant clothes as early as possible.Comprise the tradesmans such as public security, people's police, municipal administration, security personnel, driver and have huge demand to a series of security protection product.
Mainly there is hard stab-resistance body armor, flexible puncture-proof clothes and this few class of liquid stab-resistance body armor in the market.The antipricking layer of hard stab-resistance body armor is formed by the metallic plate such as special steel, titanium alloy or sheet metal processing substantially, the anti-stab excellent performance of this stab-resistance body armor, but hard heaviness, very flexible.Flexible puncture-proof clothes generally adopt aramid fiber, high-strength polyethylene to combine with high-performance ceramic and make, anti-stab functional, but quality is overweight, very flexible, with high costs, are not suitable for promoting on a large scale.Liquid stab-resistance body armor is also in conceptual phase, does not extensively introduce to the market.Although itself soft comfortable, lighter in weight, excellent shock resistance, liquid stab-resistance body armor long-term storage, anti-stab performance is had a greatly reduced quality, and also needs further research and development.
[summary of the invention]
The object of this invention is to provide a kind of anti-stab function admirable, soft comfortable, lower-cost novel two-sided shaping grid stab-resistant material and manufacturing process thereof.Research field for domestic stab-resistant material is opened up new direction by the present invention, and meets the needs of military domain and civil area.
To achieve these goals, design a kind of preparation method of double-faced forming grid stab-resistant material, comprise the following steps:
Grid cloth is tiled on the table, and fixes four limits with fixture;
Automatic dispensing machine is utilized to carry out gluing to each polymeric particles surface;
After each polymeric particles surface coats binding agent, utilize manipulator that the pattern distribution of particle according to design is bonded with grid cloth;
Repeat above-mentioned steps on the table by fixing for grid cloth turn-over, utilize manipulator that polymeric particles one is solidificated in grid cloth surface, finally prepare double-faced forming grid stab-resistant material.
Direction and the distance of each manipulator movement are shifted according to pre-set program.After all particles and grid cloth bond, polymeric particles can form different floral designs.The distance of manipulator movement is at every turn 5-20mm.The horizontal plane of polymeric particles is of a size of 3-20mm, and thickness is 0.3-2mm.
Described grid cloth raw material can be glass fibre, basalt fibre, superhigh molecular weight polyethylene fibers, one or more fibers of aramid fiber, the thread fabric of yarn.
Described polymeric particles can be one or more the processing preparations in the thermoplastic resins such as acetal resin, Merlon, polyamide, ABS resin, acrylic resin, also the compounds such as these resin matrixes and glass fibre, carbon fiber, aramid fiber, basalt fibre can be prepared into composite reinforcing material particle; Polymeric particles can also be that the processing of the thermosetting resin such as epoxy resin, acrylic resin is prepared into regular particle.
Described polymeric particles can add one or more in reinforcing agent, flexibilizer, fire retardant, look grain, hard particles, nano particle, strengthens the performance indications such as mechanical strength, hardness, toughness after polymeric particles solidification.
In the present invention, by 3-10 layer flexible puncture-proof composite according to certain angle cross laminates, hide the intergranular gap of adjacent bulk, carry out sparse suture by conventional sewing techniques between layers.The particle pattern of flexible puncture-proof composite material surface can be identical, also can be different.Adopt this double-faced forming grid stab-resistant material can produce the security protection articles for use such as stabproof vest, overcoat, armlet, knee-pad, gloves.
The advantage of double-faced forming grid stab-resistant material of the present invention is:
1. adopt very-high performance grid cloth and polymeric particles to carry out compound, grid cloth plays the effect of reinforcement, substantially increases the mechanical strength of antipricking layer.
2. polymeric particles and grid cloth compound are closely, and the distribution in discrete state, there is certain gap in whole stab-resistant material, ensures that the stab-resistant material of preparation has good softness and permeability.
3. moulding process flow process is short, and production efficiency is high.
4. polymeric particles is cheap, and raw material sources are extensive.
5. both can be used for the special type protection clothes such as processing stab-resistance body armor, for art's dresses such as public security, people's police, security personnel, municipal administration, glass processing industries, also can make the Protection Products such as Anti-thorn gloves, knee-pad, armlet, cut resistant suitcase, applied range.
