Problems solved by technology

The metal stab-resistant clothing is made of metal chips, which are combined by riveting technology. Not only is the wearing comfort and close-fitting effect poor, but also the function of resisting external impact is weak, which can easily cause internal injuries. Therefore, non-metallic stab-resistant clothing and high-performance The application of stab-resistant materials has become a trend
[0004] At present, the better non-metal stab-proof sheets on the market mainly rely on foreign imports, but due to technical trade barriers, the price is relatively expensive
Although domestic anti-stab sheets made of high-molecular-weight polyethylene materials have a certain anti-stab function, the high-molecular-weight polyethylene materials have poor damage and deformation effects on the knife tip, and the anti-stab performance is not stable enough, and the number of combined anti-stab layers is large. , the overall weight is relatively large; while the anti-stab material made of unglued aramid woven fabric, under the same conditions, its anti-stab performance is not as good as that of high-molecular polyethylene materials, and its penetration resistance is poor.

Embodiment 2

[0046] Embodiment 2 detection method

[0047] 1 appearance inspection

[0048] The appearance of the aramid-coated composite was visually inspected.

[0049] 2 size inspection

[0050] Use a measuring tool with an accuracy of 1 mm to measure the size of the aramid-coated composite material.

[0051] 3 surface density test

[0052] Use an electronic scale with an accuracy of 1g to weigh the mass per unit area and calculate the surface density.

Abstract

This patent application discloses a stab-proof sheet, especially relates to a high-performance non-metallic stab-proof sheet and its manufacturing process. The high-performance non-metal stab-proof sheet is made by painting a certain proportion of mixed resin on both sides of the aramid woven fabric, and then performing molding and drying and curing. By adding a resin matrix to the aramid woven fabric to increase the hardness of the material and enhance its mechanical properties such as impact resistance and shear strength. The mixed resin is formed by stirring epoxy resin and acetone into a mixture at a mass ratio of 3.7-4.3:1, and then mixing the mixture with polyamide resin at a mass ratio of 2:1-1.2. This patent overcomes the defects of low anti-stab performance, poor stability and high production cost in the existing non-metallic anti-stab material technology, and provides a anti-stab material with low cost, strong anti-stab performance and high stability , the cost is lower than that of imported anti-stab film.

Description

technical field [0001] The invention relates to a protective sheet, in particular to a high-performance non-metal stab-proof sheet. Background technique [0002] In recent years, due to the occurrence of international and domestic violence and terrorist incidents, the development and research of various personal protective equipment has been greatly promoted. As we all know, bulletproof materials have made great progress, but due to the difference in mechanism between bulletproof and stabproof, most bulletproof products cannot be used for stabproof, so the research and development of stabproof materials has attracted great attention, especially In a country like China that has strict gun control. [0003] Stab-resistant materials are required to protect the main organs of the human body from sharp objects such as bayonets and daggers, and at the same time ensure that the wearer's activities are not restricted. At present, the stab-proof clothing used by domestic public sec...
