Problems solved by technology

At present, most of the existing flexible anti-stab materials are made of multi-layer protective materials. Although the anti-stab effect of this product is enhanced, it is too thick and heavy to be suitable for daily protection. Lamination is usually impregnated and coated, so the protective effect cannot be guaranteed for a long time

Abstract

The invention discloses a preparation method of a soft and durable anti-penetrating material. The preparation method is characterized by comprising the following steps: (1) preparing shearing thickening liquid; (2) preparing a high performance fiber fabric with a special tissue structure, namely preparing a fabric from high performance fibers by virtue of a special tissue structure weaving process, putting the fabric into a vacuum drying oven, and drying at 120-150 DEG C for 2-3 hours; and (3) preparing the anti-penetrating material. According to the method, by virtue of reasonable tissue structure configuration on the fabric and plasma treatment on the shearing thickening liquid and the fabric, the shearing thickening liquid and the fabric are adequately compounded, so that the durabilityand flexibility of the anti-penetrating material are improved, and the soft and durable anti-penetrating material suitable for multiple environments of daily protective clothes of military police, armored military equipment, civil and industrial protection and the like is prepared.

Description

technical field [0001] The invention belongs to the field of safety protection, in particular to a method for preparing a soft and durable anti-stab material. Background technique [0002] With the continuous development of military and science and technology, the demand for protective equipment in today's society is increasing day by day. The research and development of individual protective armor materials has attracted great attention of researchers from all over the world. Personal stab-resistant armor is required not only to protect the wearer from sharp objects, but also to ensure appropriate comfort so that his actions are not excessively restricted. This means that the armor material should be light and soft, and seek a balance between effective protection, flexibility and light weight. While providing effective protection, it does not affect the wearer's flexibility of movement, and realizes it in one product as much as possible. It has comprehensive protective eff...
