Embodiment 1

[0026] Using aramid 1414 mesh cloth, the surface density is 160g / m 2 , the thickness is 0.3mm, and the warp and weft density is 40×40 (root / 10cm). Polycarbonate resin is processed into round particles with a diameter of 10mm, a particle height of 1.5mm, and a particle gap of 0.8mm, and additives such as reinforcing agents, flame retardants, and color particles are added. Three layers of this double-sided forming grid composite material are used to be laminated alternately, and then the edges of each layer are sparsely stitched to each other, and then cut to make a protective body (stab-proof liner). The total weight of the anti-stab clothing of specification 175cm, 90A prepared with this protective body is 2.3kg, and the thickness is 10.2mm. The stab-resistant clothing adopts the latest standard GA68-2008 of the public safety industry of the People's Republic of China to conduct a puncture test according to 24J energy, and the results show that the stab-resistant clothing ful...

Embodiment 2

[0034] Aramid 1414 mesh cloth is used, the surface density is 180g / m2, the thickness is 0.4mm, and the warp and weft density is 36×36 (root / 10cm). The polyamide resin is processed into square particles with a side length of 5mm, a particle height of 1.3mm, and a particle gap of 0.8mm, and additives such as reinforcing agents, flame retardants, and color particles are added. Three layers of this double-sided forming grid composite material are used to be laminated alternately, and then the edges of each layer are sparsely stitched to each other, and then cut to make a protective body (stab-proof liner). The total weight of the anti-stab clothing of specification 175cm, 90A processed with this protective body is 2.4kg, and the thickness is 9.6mm. The stab-resistant clothing adopts the latest standard GA68-2008 of the public safety industry of the People's Republic of China to conduct a puncture test according to 24J energy, and the results show that the stab-resistant clothing f...

Embodiment 3

[0042]Glass fiber mesh cloth is used, the surface density is 160g / m2, the thickness is 0.4mm, and the warp and weft density is 34×34 (root / 10cm). Epoxy resin is processed into round particles with a diameter of 10mm, a particle height of 1.2mm, and a particle gap of 0.8mm. Add tougheners, diluents, and color particles to the epoxy resin. Four layers of this double-sided forming grid composite material are used to be laminated alternately, and then the edges of each layer are sparsely stitched to each other, and then cut to make a protective body (stab-proof liner). The total weight of the anti-stab clothing of specification 175cm, 90A prepared by this protective body is 2.8kg, and the thickness is 11.4mm. The stab-resistant clothing adopts the latest standard GA68-2008 of the public safety industry of the People's Republic of China to conduct a puncture test according to 24J energy, and the results show that the stab-resistant clothing fully meets the technical requirements st...

Abstract

The invention relates to a preparation process of a double-side formation grid anti-piercing material. The method comprises the following steps: tiling grid cloth on a working table and fixing four sides by using clamps; coating an adhesive on the surface of each macromolecular particle by using an automatic dispenser; after the adhesive is coated on the surface of each macromolecular particle, discretely adhering the particles to the grid cloth by using a manipulator according to designed pattern distribution; turning over the grid cloth and fixing to the working table, repeating the step, and curing the macromolecular particles on the surface of the grid cloth by using the manipulator to finally prepare the double-side formation grid anti-piercing material. The grid cloth with ultrahigh performance is compounded with the macromolecular particles, and the grid cloth has the effect of reinforcing ribs, so that the mechanical strength of the anti-piercing layer is greatly improved. The macromolecular particles and the grid cloth are tightly compounded and are distributed in the discrete state, so that the entire anti-piercing material as a certain gap, and good softness and air permeability of the prepared anti-piercing material are guaranteed.

Description

[technical field] [0001] The invention relates to a functional protective material and a manufacturing process thereof, in particular to a novel stab-proof material with a double-sided formed mesh and a manufacturing process thereof. [Background technique] [0002] With the development of society and economy, public safety issues have become more and more prominent, people are becoming more and more aware of the importance of their own safety protection, and the state has also increased its support for the field of safety protection. In recent years, stab-proof clothing has been gradually separated from bullet-proof clothing, and has been valued and deeply researched by researchers from various countries. Stab-resistant clothing has become a current hot research object. In September 2009, the Ministry of Public Security of my country issued the "Gongzhuang Cai [2009] No. 705 Notice on Issuing the Tactical and Technical Indicators of Bulletproof and Stabproof Clothing", hopin...
