Problems solved by technology

Chinese patent CN201210364412 discloses a kind of anti-stab body which is made of polymer polyethylene and aramid fiber material by three-dimensional loom. Although the anti-stab body made of this material has good protection performance and soft comfort, The weaving efficiency of the three-dimensional loom is not high, and the cost of manufacturing is relatively high
Chinese patent CN201210084695 discloses a preparation method of shear thickening liquid / aramid fiber composite material, which realizes intelligent protection by compounding shear thickening liquid and aramid fiber material. This kind of protective body impregnated with shear thickening liquid is not easy Hold, the shear thickener will flow and affect the protection performance

preparation example Construction

[0039] like image 3 , the present invention also discloses a preparation method of a double-sided riveted flexible stab-proof material, which is composed of a flexible fabric 1 and several small protective modules 2 arranged on both sides of the flexible fabric, the flexible The fabric 1 and the small protective modules 2 on both sides are fixedly connected by means of double-sided riveting, and its specific preparation method includes the following preparation steps:

[0040] S1, prepare the small protective module, and make the small protective module by injection molding or mechanical processing according to the preset parameters of the small protective module;

[0041] Among them, the small protective module made of thermoplastic reinforced composite material is made by injection molding; the small protective module made of metal is made by mechanical processing. The preset parameters of the small protective module include the shape, size and thickness of the small prote...

Embodiment 1

[0050] Among the flexible anti-stab materials, the material of the small protective module 2 is a composite reinforcement material of carbon fiber short fiber and thermoplastic nylon 66, the mass fraction ratio of carbon fiber short fiber and nylon material is 1:3, and the side length of the small protective module 2 is 15 mm An equilateral triangle with a thickness of 1mm, as attached Figure 4 In the form shown in , the lower mold has three rivets 4 for riveting, and the small protective module 2 of the upper mold has three through holes 5 at the riveting position, and there are bayonet holes on the through holes. image 3 After the assembly is completed, use heat welding to flatten the protruding rivets to the bayonet to fix them firmly.

[0051] The flexible fabric sandwiched between the small protective modules is plain fabric made of aramid yarn, the weight of the fabric is 200 grams per square meter, and the gap between the small protective modules is 0.3mm.

[0052] T...

Embodiment 2

[0054] In the flexible anti-stab material, the protective small module material that forms the protective material layer is made of aramid fiber staple fiber and polycarbonate reinforced composite material. The modules are made as squares with side lengths of 10 mm and a thickness of 1.5 mm. The flexible connection material sandwiched in the middle can be made of high-strength polyethylene filament material and is a plain weave fabric with a grammage of 200 grams per square meter. The four corners of the square protective small module are respectively designed with the riveting holes of the upper mold and the rivets of the lower mold that can be riveted in position. According to the manufacturing process of the protective material, after the alignment riveting is completed, it is fixed by heat welding to ensure the protection of the small module. fastness.

[0055] The number of protective materials thus produced is 3 layers of protective layers, and the total mass of the inn...

Abstract

The invention discloses a two-surface-riveted flexible stab-resistant material and a preparation method thereof. The two-surface-riveted flexible stab-resistant material comprises flexible shell fabric and a plurality of small protective modules fixedly arranged on two sides of the flexible shell fabric in a two-surface-riveted mode. The multiple small protective modules are arranged according to a certain sequence, and gaps exist between the adjacent small protective modules. The flexible shell fabric is woven by a chemical fiber material or high-strength and high-modulus material and used for tightly connecting the small protective modules on the two sides. The small protective modules are made of thermoplastic reinforced composite materials or metal materials. The invention further discloses the preparation method for the two-surface-riveted flexible stab-resistant material. Stab-resistant garments and protective articles of various styles can be processed through the two-surface-riveted flexible stab-resistant material, the stab resistance of the stab-resistant material is improved, and the softness of the stab-resistant material is also improved to the maximum extent.

Description

technical field [0001] The invention relates to a flexible anti-stab material and a preparation method thereof, in particular to a double-sided riveted flexible anti-stab material and a preparation method thereof. Background technique [0002] In recent years, terrorist attacks have continued to occur in various countries, and personnel from various countries have stepped up research and development in the field of security protection. In our country, with the development of social economy and the improvement of people's awareness of safety protection, the demand for safety protection equipment is increasing. The fourth key development area in the "Twelfth Five-Year Plan for Industrial Textiles" specifically mentions the development of flexible stab-resistant and cut-resistant fabrics, so the development of safety protection materials is in line with the development direction of the national textile industry, and flexible stab-resistant materials are used as a safety protect...
