Embodiment 1

[0022] As shown in Figure 1, a flexible bullet-proof and stab-proof material is prepared by the following steps: (1) The gram weight is 20g / m 2 The EVA melt film is laid on a gram weight of 200g / m 2 The upper surface of the aramid fiber fabric was heated to 160° C., and hot-pressed to make the EVA material penetrate into the upper side of the fiber fabric to obtain Material 1. (2) Prepare the mixed solution of silicon carbide particles and phenolic resin by mechanical stirring method. The mass ratio of silicon carbide particles and phenolic resin is 1:1, and the average particle size of silicon carbide particles is 50 μm. Brush the mixed solution on the fiber fabric of material 1 3 On the side containing thermoplastic elastomer 2, control the brushing amount to 100g / m 2 , 150°C high temperature flattening, after the resin is cured, the mold is released, and the passivation layer 1 is produced to obtain material 2; (3) The shear thickening liquid with a solid content of 66% is...

Embodiment 2

[0025] As shown in Figure 1, a flexible bullet-proof and stab-proof material is prepared by the following steps: (1) The gram weight is 10 g / m 2 The TPU melt film is laid on a gram weight of 150g / m 2 The upper surface of the PBO fiber fabric is heated to 180° C., and hot-pressed to form the TPU material into the upper side of the fiber fabric 3 to obtain material 1. (2) The mixture of boron carbide particles and vinyl ester resin is prepared by mechanical stirring method, the mass ratio of boron carbide particles and vinyl ester resin is 1:2, the average particle size of boron carbide particles is 100 μm, and the mixture is painted on The fiber fabric of material 1 contains one side of thermoplastic elastic material, and the control brushing amount is 120g / m 2 , press at room temperature, release the mold after the resin is cured, and produce a passivation layer 1 to obtain material 2; (3) Dilute the shear thickening liquid with a solid content of 70% with methanol at a volum...

Embodiment 3

[0028]As shown in Figure 1, a flexible bulletproof and stab-proof material is prepared by the following steps: (1) The gram weight is 15g / m 2 The EVA melt film is laid on a gram weight of 300g / m 2 The upper surface of the aramid fiber fabric is heated to 160° C., and hot-pressed to form the EVA material into the upper side of the fiber fabric 3 to obtain material 1. (2) Prepare the mixed solution of silicon carbide particles and epoxy resin by mechanical stirring method. The mass ratio of silicon carbide particles and epoxy resin is 1:3, and the average particle size of silicon carbide particles is 10 μm. Brush the mixed solution on material 1 On the side of the fiber fabric containing thermoplastic elastic material, the control brushing amount is 150g / m 2 , high temperature pressing at 150°C, release the mold after the resin is cured, make a passivation layer 1, and obtain material 2; (3) Dilute the shear thickening liquid with a solid content of 68% with acetone at a ratio ...

Abstract

The invention discloses a flexible bulletproof stab-resistant material and a preparing method thereof. The flexible bulletproof stab-resistant material includes a basic layer and a passivation layer,the basic layer includes fabric, a thermoplastic elastic material which penetrates into the fabric after being subjected to hot melting penetrates into one side of the fabric, and shear thickening fluid is dispersed in the portion, where the thermoplastic elastic material does not penetrate, of the fabric; the passivation layer is prepared by smearing a mixed liquid of ceramic particles and thermosetting resin to the side, containing the thermoplastic elastic material, of the fabric and conducting curing, and protective membranes cover the basic layer and the passivation layer through vacuuming. The preparing method is used for preparing the flexible bulletproof stab-resistant material. By the adoption of the preparing method, the flexibility of the bulletproof stab-resistant material is greatly improved, and light, comfortable, bulletproof and stab-resistant effects are provided.

Description

technical field [0001] The invention relates to a bulletproof and stabproof clothing. Background technique [0002] Maintaining social public safety and improving on-site emergency response capabilities for social emergencies are the prerequisite and important guarantee for building a harmonious society. At present, the world's anti-terrorism situation is becoming more and more severe, and various forms of social violent crimes at home and abroad continue to occur. The lives of soldiers, police and various security groups are facing increasingly serious threats. Bullet-proof and stab-proof equipment is widely used. However, due to the large difference between the bullet-proof mechanism and the stab-proof mechanism of the material, the stab-proof performance of the bullet-proof material is not ideal, and the conventional stab-proof material has almost no bullet-proof function. In practical applications, combat personnel may face multiple threats such as bullets and daggers a...
