Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] refer to figure 1 Shown, a kind of floating bulletproof board, this bulletproof board comprises five layers of structure:

[0028] The first layer 101 is an aramid bulletproof plate layer, which is made of aramid bulletproof material and prepared by hot pressing;

[0029] The second layer 102 is an adhesive layer, mainly used for bonding the first layer 101 and the third layer 103;

[0030] The third layer 103 is a foam material layer; this layer has relatively large buoyancy and strong elastic recovery force, and is mainly used for floating on the water surface and buffering and shape recovery after being shot;

[0031] As an example, the foam material layer is: one or a combination of PE foam material, EVA foam material or PP foam material;

[0032] According to different actual needs, the foaming material layer can be prepared wi...

Abstract

A floating type armor plate comprises five layers of structures, wherein the first layer is an aramid fiber armor plate layer, made of aramid fiber bulletproof materials and formed in a hot press molding mode; the second layer is an adhesive layer and mainly used for bonding the first layer and the third layer; the third layer is a foam material layer; the fourth layer is an adhesive layer and mainly used for bonding the third layer and the fifth layer; the fifth layer is an aramid fiber armor plate layer, also made of aramid fiber bulletproof materials and formed in a hot press molding mode. The armor plate manufactured through the special design has the floating function, and after shooting test, the convex and concave value of the back portion of the armor plate is smaller and the armor plate has the certain blunt resistance capacity. The armor plate is simple in structural design, the manufacturing process is smooth, the manufacturing cost is not high, and the armor plate is suitable for common fighting, task duty and special wading fighting.

Description

technical field [0001] The patent of the present invention relates to the technical field of a bulletproof board and its preparation method, especially a floating bulletproof board and its preparation method. The bulletproof board adopts a special structure design and is made by an original preparation method. It can not only float on the water surface In addition, it can also effectively reduce the dent value on the back of the bulletproof plate after being shot. Background technique [0002] The traditional bulletproof board is made of aramid fiber, and the aramid fiber bulletproof board is mainly made of aramid UD cloth material, that is, the unidirectional laminate material that is wound or continuously prepared is mainly used. This material has excellent bulletproof performance and will The multi-layer aramid fiber UD cloth is superimposed and then hot-pressed to prepare the aramid fiber bullet-proof board. Because the density of the bullet-proof board is higher than th...
