Embodiment 1

[0046] The soft stab-resistant layered material described in this embodiment is made of 24 layers of non-woven fabrics, and the layers can slide freely.

[0047] The preparation process is as follows: the linear polyethylene powder with a viscosity-average molecular weight of 3.5 million units (the ratio of weight-average molecular weight to number-average molecular weight is 4) is used as raw material, and the tensile breaking strength is 25g / d, and the modulus It is a high-strength polyethylene fiber of 1000g / d, a monofilament fineness of 3d, and an average length of 100mm, and uses polyphenylene sulfide type for anti-static surface treatment.

[0048] Then open and comb, use acupuncture equipment, the acupuncture density is 250 needles / cm 2 , the surface density is 200g / m 2 24 layers of non-woven fabric base material, then superimposed with 24 layers, pressurized at 12MPa for 40 minutes, peeled off layer by layer under normal temperature and pressure, stacked in the origin...

Embodiment 2

[0059] The soft anti-stab layered material described in this embodiment is formed by stacking five layers of non-woven fabrics, and the layers can slide freely.

[0060] The preparation process is as follows: the linear polyethylene powder with a viscosity-average molecular weight of 5 million units is used as raw material, and the tensile breaking strength is 28g / d, the modulus is 900g / d, the single filament fineness is 5d, and the average High-strength polyethylene fibers with a length of 110mm and anti-static surface treatment with PVC type.

[0061] Then open and comb, use acupuncture equipment, the acupuncture density is 300 needles / cm 2 , the surface density is 220g / m 2 The non-woven fabric base material is superimposed with 5 layers, pressurized at 10MPa for 30 minutes, peeled off layer by layer at normal temperature and pressure, stacked in the original order, and sprayed with paraffin oil between layers to make a stab-resistant surface with a density of 5.6kg / m 2 Th...

Embodiment 3

[0063] The soft anti-stab layered material described in this embodiment is formed by stacking 30 layers of non-woven fabrics, and the layers can slide freely.

[0064] The preparation process is as follows: the linear polyethylene powder with a viscosity-average molecular weight of 4 million units is used as raw material, and the tensile breaking strength is 22g / d, the modulus is 900g / d, the single filament fineness is 3d, and the average High-strength polyethylene fibers with a length of 120mm and anti-static surface treatment with polyacetylene type.

[0065] Then open and comb, use acupuncture equipment, the acupuncture density is 150 needles / cm 2 , the surface density is 180g / m 2 Then use 30 layers of non-woven fabric substrates, then stack them with 30 layers, pressurize at 12MPa for 80 minutes, peel them off layer by layer at normal temperature and pressure, stack them in the original order, and spray paraffin oil between layers to make a puncture-resistant surface with...

Abstract

The soft prick-preventing layered material consists of several layers of non-woven fabric and capable of sliding relatively. Several layers of non-woven fabric of ultrahigh molecular weight polyethylene fiber are produced through pressing, layer-by-layer stripping and superposing into the prick-preventing material with interlayer sliding. The soft prick-preventing layered material of the present invention is light, soft, comfortable and excellent in preventing dynamic pricking, so that it may be used in making prick-preventing suit, explosive eliminating suit, anti-explosive sheet, explosion-preventing wall, etc.

Description

technical field [0001] The invention relates to a multi-layer composite material, in particular to a soft stab-proof layered material, its preparation method and its application. Background technique [0002] The anti-stab armor used on ancient battlefields since ancient times, and the body armor used on modern battlefields since World War II are mostly hard, because they are often made of leather, steel, alloy, resin composite materials, etc., not only hard but also Heavy, it is difficult to move quickly, and individual combat capabilities are limited to a certain extent. [0003] The initial methods of stab-proof clothing are: metal mesh production, metal or composite material scale production, for example, Chinese patent CN92224871.0, the name of the utility model is metal mesh anti-stab layer, which is used for the metal mesh of security wearables. The anti-stab layer is made of a metal loop buckle adjacent to the structure of four metal rings, which is suitable for use...
