Problems solved by technology

[0003] It can be seen from the above prior art that the soft bulletproof cloth is mainly realized by selecting a low-modulus elastomer adhesive, although the low-modulus adhesive is easy to produce a product with good flexibility and is conducive to ballistic performance However, it is not conducive to reducing the back convex deformation of the product after being shot, and the large back convex deformation of the bulletproof cloth is likely to cause non-penetrating damage to the human body; the hard bulletproof cloth is mainly through the selection of high modulus adhesives Although it is beneficial to reduce the back convex deformation of the product after being shot, the anti-ballistic performance will also be affected to a certain extent
[0004] At present, because different application scenarios have different requirements for bulletproof fabrics, in order to meet the various needs of customers at the same time, manufacturers generally produce soft bulletproof fabrics and hard bulletproof fabrics at the same time, and adopt this way of increasing product types to meet customers. The demand for different bulletproof fabrics reduces production efficiency and increases production costs

[0027] The invention provides a method for preparing a multipurpose composite cloth with protective properties, the method comprising the following steps:

[0028] 1) Leading high-strength and high-modulus fibers from the creel to make a fiber layer arranged in parallel and straight in one direction, and soaking the fiber layer in a compounded water-based adhesive to obtain a fiber layer containing glue;

[0029] 2) Evaporating part of the water in the glue-containing fiber layer, and then attaching a mesh film as a carrier to one side of the glue-containing fiber layer, drying it below 100°C and then cooling to obtain a unidirectional non-woven fabric;

[0030] 3) At a temperature lower than the melting temperature of the mesh adhesive film, two layers of unidirectional non-weft fabrics are laminated orthogonally to obtain a composite cloth, and in the composite cloth, the mesh adhesive of the two layers of unidirectional non-weft fabrics Membranes are located on the outside....

Abstract

The invention relates to multipurpose composite cloth with protection performance, a preparation method and application thereof. The preparation method comprises the following steps: 1) preparing high-strength and high-modulus fibers into a fiber layer which is arranged in a unidirectional parallel straightening manner, and infiltrating the fiber layer in a compound water-based adhesive to obtain an adhesive-containing fiber layer; 2) evaporating a part of moisture of the adhesive-containing fiber layer, then attaching the reticular adhesive film serving as a carrier to one side of the adhesive-containing fiber layer, drying at a temperature of 100 DEG C or below, and cooling to obtain one-way non-woven cloth; and 3) at a temperature lower than the melting temperature of the reticular adhesive film, carrying out orthogonal lamination compounding on the two layers of one-way non-woven cloth to obtain the composite cloth. Compared with the prior art, when the composite cloth is used for a soft body armor, the soft characteristic is achieved, and back protrusions can be reduced; and when the composite cloth is used for a hard armor scene, the reticular adhesive film can be melted into a whole through heating and pressurizing, so that the bonding strength between the layers of the composite material and the rigidity of the armor after pressing are improved.

Description

technical field [0001] The invention belongs to the technical field of bulletproof composite materials, and relates to a multipurpose composite cloth with protective performance, a preparation method and application thereof. Background technique [0002] At present, lightweight bulletproof composite materials mostly use high-performance fiber-reinforced resin matrix to prepare bulletproof composite fabrics, and the fibers include high-performance organic fibers such as ultra-high molecular weight polyethylene (UHMWPE) fibers, aramid fibers, and polyimide fibers. Bulletproof composite fabrics are generally divided into soft bulletproof fabrics and hard bulletproof fabrics according to different application scenarios. For example, DSM’s ultra-high molecular weight polyethylene fiber bulletproof fabrics are divided into soft Dyneema SB series and hard Dyneema HB series. ; Chinese patent CN101511580A discloses a method of manufacturing an improved soft non-weft cloth, while Chin...
