Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength polyurethane / ceramic structure bullet-proof plate in order to overcome the problem of damage to human tissue and bones caused by the instantaneous deformation of the bullet-proof plate in the prior art. The front surface, rear surface, and four narrow sides of the bulletproof board are sprayed with polyurethane material to make the material covered as a whole. According to the different bulletproof effects achieved by the material and structure of the bulletproof board, different thicknesses of polyurethane material are sprayed on different surfaces. To meet the reinforcement, toughening and cushioning requirements here; it can well resist the shooting of bullets, and at the same time use the performance of polyurethane to buffer the instantaneous deformation caused by the kinetic energy of bullet shooting, protecting the wearer's human tissue and bones from damage

Abstract

The invention relates to the field of bulletproof equipment, and discloses an armor of a high-strength polyurethane / ceramic structure. The armor comprises a ceramic bulletproof layer and a coating layer, wherein the coating layer coats the ceramic bulletproof layer; a lap joint agent is arranged between the ceramic bulletproof layer and the coating layer; and the thickness of the coating layer ondifferent surfaces of the ceramic bulletproof layer is different. According to the armor, a polyurethane material of different thicknesses is sprayed on different surfaces of the ceramic bulletproof layer, strengthening, toughening and buffering requirements are met, the armor well resists shooting of bullets, instantaneous deformation generated by bullet shooting kinetic energy is buffered by virtue of performance of polyurethane, and body tissues and skeletons of a wearer are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of bulletproof equipment, in particular to a high-strength polyurethane / ceramic structure bulletproof plate. Background technique [0002] As an important personal protective equipment, the bulletproof plate is generally used with bulletproof vests. It is an effective equipment to protect individual soldiers from direct damage from projectiles and shrapnel. After decades of development, there have been many outstanding innovations and innovations in materials and structures. Application, such as patent CN201420638529.1 involves a kind of ceramic bulletproof board, including: a backboard; a plurality of bulletproof ceramic blocks are arranged on the backboard, and the arrangement shape of these bulletproof ceramic blocks is within the length of the backboard It is divided into multiple levels in the extension direction, so that the seams of the bulletproof ceramic blocks between adjacent levels are staggered, thereby i...
