Problems solved by technology

[0003] At present, hard bullet-proof and stab-proof clothing made of metal such as hard steel plate and special steel is gradually decreasing. The main reason is that it is hard and bulky, has poor flexibility, and is prone to ricochets.
Secondly, as the U.S. JHRG LLC company (US6280546) discloses a kind of anti-stab clothing that adopts thermoplastic film and the fabric that contains more than 25% aramid, UHMWPE high-performance fiber to prepare, has good anti-shear, anti-puncture performance, but Air permeability is relatively poor, wearing stuffy, obviously uncomfortable; U.S. Honeywell company (CN101356054A) has announced anti-liquid-absorbing flexible bullet-proof material and production method thereof and the product made thereby, and this composite material comprises multiple non-woven fibrous layers, fiber The layer is formed by a network structure of high-tenacity fibers embedded in a matrix of thermoplastic polyurethane resin. This material has a certain degree of water resistance and softness, but it is thicker, bulky to wear, and bulletproof. General; Chinese patent (CN101799257A) discloses a kind of flexible bulletproof armor, and it comprises the shell of complete closure, is filled with thick viscous liquid in the shell, places blocking net again, is placed in the rear part of thick viscous liquid with high Strength Alloy Plate
This kind of bulletproof armor prevents bouncing performance better, and alleviates the non-penetrating damage of organ tissue, but simply combines alloy plate and viscous liquid, still wears bulky, affects to carry out action; Chinese patent (CN101871748A) discloses A soft anti-stab and anti-ballistic material comprises a layer of bullet-proof fiber fabric, a layer of shear-thickening liquid composite fiber fabric and a layer of thermoplastic resin composite fiber fabric. However, a variety of fabrics are compounded, the thickness is thicker, and the wear is more bloated

Abstract

The invention relates to a preparation method of a semi-liquid state bulletproof and puncture-proof composite material, the bulletproof and puncture-proof composite material and a bulletproof and puncture-proof protection inner core. The preparation method comprises the following steps that 1, thermosetting resin grids are prepared; 2, an SiO2 / PEG mixed system solution is prepared; and 3, the semi-liquid state bulletproof and puncture-proof composite material is prepared, at least one layer of thermosetting resin grid is laid on a high-performance fabric according to a certain laying layer angle, the SiO2 / PEG mixed system solution is evenly coated in meshes of the thermosetting resin grids, and a high-performance fabric is laid on the thermosetting resin grid on the uppermost layer. In thestep 1, a thermosetting resin / hard particle solution is evenly coated on the crossed points of the grid. The method has the advantages that the grid is filled with the semi-liquid state SiO2 / PEG mixed solution and has the certain deformation capacity; and the meshes of the thermosetting resin grids are filled with the SiO2 / PEG mixed system solution, the system stability is high, SiO2 does not precipitate through long-term storage, and the bulletproof performance is stable.
