Problems solved by technology

[0002] Personal protective materials are mainly divided into three categories: hard, semi-rigid and soft. Among them, the hard is too rigid and heavy, and the soft has great defects in air permeability, and it is very bloated to wear. The semi-rigid has a good The anti-stab performance and air permeability are also very good, but there is a certain gap between the protective modules, which leaves a great safety hazard
[0003] Chinese patent CN 201610146905 discloses a kind of anti-stab clothing arranged without gaps, flexible fabric and several small protective modules fixedly arranged on both sides of the flexible fabric, the several small protective modules are arranged in a certain way without gaps, which greatly improves the It affects the air permeability of the stab-resistant clothing, and the connection is thin, so it is difficult to meet the stab-resistant requirements
Chinese patent CN201710427713 discloses a stab-resistant clothing based on the principle of friction self-locking, which ignores the fact that the edges are thin and easy to penetrate, and relying on the clamping between two modules, it is difficult to hinder the puncture of the knife tip
Chinese patent CN 201410451972 discloses a double-sided forming mesh stab-proof material, which lays layers of multi-layer mesh materials to cover the gap, but this ignores the flexibility of the stab-proof material

preparation example Construction

[0033] The preparation method of the above-mentioned embedded flexible anti-stab material comprises the following steps:

[0034] S1: Component 1 and Component 2 are obtained through injection molding technology;

[0035] S2: Bonding component one 1 and component two 2 obtained in step S1 to the upper and lower layers of flexible base fabric 3 respectively according to certain rules and drying, the obtained flexible base fabric 3 is as follows: Figure 4 , 5 shown;

[0036] S3: The components on the two layers of flexible base cloth 3 in the S2 step are mutually fitted (such as Figure 6 shown) and sutured to obtain a flexible stab-resistant material.

Embodiment 1

[0038] In the embedded flexible anti-stab material provided in this embodiment, component one 1 and component two 2 are formed by mixing ultra-high molecular weight polyethylene short fibers and thermoplastic polyurethane through injection molding, wherein the high-strength and high-modulus fiber and thermoplastic resin The mass fraction ratio is 1:3. Make component one 1 into a regular quadrangular truss whose lower base length is 20mm, upper base length is 16mm, and height is 2mm. module. The flexible base fabric 3 is aramid plain weave fabric with an area density of 130g / m 2 , the thickness is 0.28mm, the sewing thread 4 is aramid thread, and the fineness is 200D.

[0039] The first component 1 and the second component 2 are prepared by using thermoplastic polyurethane and high-strength and high-modulus short fibers through injection molding technology. And the prepared component one 1 and component two 2 are bonded to the upper and lower layers of aramid base cloth by t...

Embodiment 2

[0041] In the embedded flexible anti-stab material provided in this embodiment, component one 1 and component two 2 are formed by mixing aramid short fiber and thermoplastic polyurethane through injection molding, wherein the mass fraction ratio of high-strength and high-modulus fiber to thermoplastic resin is It is 1:3. Make component one 1 into a regular quadrangular truss whose lower base length is 20mm, upper base length is 16mm, and height is 2mm. module. The flexible base fabric 3 is aramid plain weave fabric with an area density of 130g / m 2 , the thickness is 0.28mm, the sewing thread 4 is aramid thread, and the fineness is 200D.

Abstract

The invention discloses an embedded type flexible anti-piercing material and a preparation method thereof. The embedded type flexible anti-piercing material comprises two layers of flexible base cloth, a component I and a component II, wherein the two layers flexible base cloth are compounded with each other, the bottom surface of the component I is fixed on the inner side of the lower-layer flexible base cloth, and the top surface of the component II is fixed on the inner side of the upper-layer flexible base cloth; the shape of the component I is a regular quadrangular frustum, the bottom surface of the component II is square, and the top surface of component II is octagonal, the side face where four edges are located is a trapezoid matched with the side face of the adjacent component I,and the side face where the other four edges are located is a triangle matched with the corresponding side face of the diagonal adjacent component II. The preparation method comprises the following steps of adhering the component I and the component II to the inner sides of the two layers of flexible base cloth according to a rule respectively, and drying; aligning the component I and the component II on the two layers of flexible base cloth and then compounding with each other to obtain the flexible anti-piercing material. The embedded type flexible anti-piercing material can be applied to various kinds of anti-piercing or protective articles, the soft and breathable performances of the anti-piercing material are greatly improved on the premise that the anti-piercing performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of individual protective materials, in particular to a flexible anti-stab material in which upper and lower layers of small protective modules are fitted together and are in a free state and a preparation method thereof. Background technique [0002] Personal protective materials are mainly divided into three categories: hard, semi-rigid and soft. Among them, the hard is too rigid and heavy, and the soft has great defects in air permeability, and it is very bloated to wear. The semi-rigid has a good The anti-stab performance and air permeability are also very good, but there is a certain gap between the protective modules, which leaves a great safety hazard. [0003] Chinese patent CN 201610146905 discloses a kind of anti-stab clothing arranged without gaps, flexible fabric and several small protective modules fixedly arranged on both sides of the flexible fabric, the several small protective modules are arr...
