Embodiment 1

[0019] First take by weighing 1000g acrylate adhesive aqueous solution and 100g ethylene-vinyl acetate adhesive emulsion respectively, wherein the solid content of acrylate adhesive aqueous solution is 50%, and the solid content of ethylene-vinyl acetate adhesive emulsion is 47%, after mixing uniformly, respectively Weigh 66g of triglycidyl isocyanurate (TGIC) and 5.5g of sodium dodecylbenzenesulfonate, and add them into the glue solution, and mix the glue solution thoroughly for later use.

[0020] The aramid fiber is wound in parallel on the winding machine, and then the fiber is immersed in the above glue solution, and the yarn is spread by a specific spinning equipment. The adhesive used in this example is the above-mentioned modified adhesive. After dipping, spread the glue evenly with a squeegee, and dry it under a 50°C electric resistance wire. After it is completely dry, rotate the cloth sample 90°, and use the same The method is to carry out orthogonal compounding of ...

Embodiment 2

[0023] Change the ethylene-vinyl acetate adhesive emulsion into 10g in Example 1, and the remaining conditions are the same as in Example 1. Adopt Type 54 7.62mm pistol, Type 51 7.62 pistol bullet (lead core), according to GA141-2010 bulletproof level 2 test, the results are shown in Table 1.

Embodiment 3

[0025] In embodiment 1, triglycidyl isocyanurate (TGIC) 11g, all the other conditions are identical with embodiment 1. Adopt Type 54 7.62mm pistol, Type 51 7.62 pistol bullet (lead core), according to GA141-2010 bulletproof level 2 test, the results are shown in Table 1.

Abstract

The invention provides a method for making bulletproof composite materials through aramid fiber non-woven cloth, and relates to the field of resin modification. A resin composition comprises an acrylate adhesive water solution, ethylene-vinyl acetate copolymer emulsion, cross-linking agents and emulsifying agents. All the components are mixed according to a proper proportion to make a modification adhesive system, and a bulletproof composite plate can be directly made through compression without carrying out secondary adhesive coating on the aramid fiber non-woven cloth prepared through adhesives. Shooting tests indicate that the bulletproof plate made through the aramid fiber non-woven cloth is good in bullet proofing property, high in safety margin, low in weight and capable of obviously improving safety of war fighters.

Description

Technical field: [0001] The invention relates to a method for preparing an aramid non-weft fabric for bulletproof composite materials, and furthermore, relates to an aramid bulletproof product applicable to the preparation of bulletproof composite materials. Background technique: [0002] Bulletproof composite materials are essential life protection equipment for combatants, especially the demand for bulletproof composite composite materials is increasing year by year. At present, Western developed countries such as the United States and Europe have been equipped with high-performance fiber composite bulletproof materials. my country's application of aramid bulletproof composite materials in transportation vehicles started relatively late, and it is still at a disadvantage compared with foreign countries. The protective armor of military vehicles and military aircraft in our country is still mainly made of steel plates, resulting in excessive mass of transport tools, increas...
