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

A kind of floatation type armour and preparation method thereof

Technical field

Patent of the present invention relates to a kind of armour and preparation method thereof technical field, especially a kind of floatation type armour and preparation method thereof, this armour adopts special construction design, be made by the preparation method of original creation, not only can swim on the water surface, can also effectively reduce after armour is hit by a bullet, the depression value that its back produces.

Background technology

Traditional armour adopts aramid fiber preparation, aramid fiber armour is mainly based on aramid fiber UD cloth material, namely unidirectional laminated material that is Wrapping formed or continuous production is adopted to be main, this material has excellent ballistic performance, multilayer aramid fiber UD cloth is carried out hot-formingly after superposition be namely prepared into aramid fiber armour, this armour is because its density value is higher than the density of water, so traditional armour does not possess function floating on the water;

Traditional armour does not only possess the function at water float, and itself does not belong to waterproof material, long-time chance water can reduce bulletproof effect, when fighting in the wild or execute the task, the flak jackets that tradition bullet resistant material makes and the additional equipment with float function with the use of time, also individual soldier's load be can increase, the ability to act of soldier and the normal performance of tactical effect affected.

When traditional armour runs into gunslinging, back can form very large depression usually, and not only impact continues comfort sense when dressing, and also can cause very large contusion to user.

Summary of the invention

The object of the invention is, provide a kind of floatation type armour and preparation method thereof, solve traditional armour and do not possess floating capacity, and gunslinging back part caves in excessive technical deficiency, this invention structure &processes is simple, and cost is low, powerful.

For solving the problems of the technologies described above, the invention provides a kind of floatation type armour, this armour comprises five-layer structure:

Described ground floor is the shellproof flaggy of aramid fiber, and this layer adopts aramid fiber bullet resistant material, is prepared from by hot-forming;

The described second layer is adhesive layer, is mainly used in bonding ground floor and third layer;

Described third layer is foamed material layer; This layer of buoyancy is comparatively large, and elastic restoring force is comparatively strong, mainly plays and recovers for the floating of the water surface and the buffering after being hit by a bullet and shape;

Illustrate as one, described foamed material layer is: the one in PE expanded material, EVA expanded material or PP expanded material or combination;

Described foamed material layer can, according to different actual needs, adopt different foam process to prepare different coefficient of foaming, and then obtains the different expanded material of density and hardness;

Described 4th layer is adhesive layer, is mainly used in bonding third layer and layer 5;

Described layer 5 is the shellproof flaggy of aramid fiber, and this layer adopts aramid fiber bullet resistant material equally, is prepared from by hot-forming.

A kind of preparation method of floatation type armour:

Step one: cutting aramid fiber UD cloth is suitable shape, and described ground floor and layer 5 are separated lamination, be positioned over respectively hot press carries out hot-forming;

Step 2: the parameter of hot press: compacting pressure adopts: 5Mpa, press temperature: 130 degrees Celsius, the compacting dwell time: 10 minutes;

Step 3: respectively at the contact surface of described ground floor and third layer, and the even brushing second layer of the contact surface of described third layer and layer 5 and the 4th layer of adhesive layer are symmetrical to layer 5 by ground floor after brushing evenly, be superimposed uniformly;

Step 4: the semi-finished product be evenly superimposed are placed on press to carry out cure under pressure shaping;

Step 5: the temperature of described press is normal temperature, and pressure is 1Mpa, and the press time is 1 minute.

Step 6: press compacting terminates rear taking-up, and namely finished product has been prepared.

Beneficial effect of the present invention:

1, this bright armour completed by particular design not only has float function, and after being tested by gunslinging, it is less that this armour back convex-concave falls into value, and possesses certain resistance to blunt and hinder ability;

2, this armour structural design is simple, and manufacture craft is smooth, and cost is not high, is applicable to the on duty and special type of common operation, task and paddles operation.

Detailed description of the invention

Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail.

With reference to shown in Fig. 1, a kind of floatation type armour, this armour comprises five-layer structure:

Described ground floor 101 is the shellproof flaggy of aramid fiber, and this layer adopts aramid fiber bullet resistant material, is prepared from by hot-forming;

The described second layer 102 is adhesive layer, is mainly used in bonding ground floor 101 and third layer 103;

Described third layer 103 is foamed material layer; This layer of buoyancy is comparatively large, and elastic restoring force is comparatively strong, mainly plays and recovers for the floating of the water surface and the buffering after being hit by a bullet and shape;

Described 4th layer 104 is adhesive layer, is mainly used in bonding third layer 103 and layer 5 105;

Described layer 5 105 is the shellproof flaggy of aramid fiber, and this layer adopts aramid fiber bullet resistant material equally, is prepared from by hot-forming.
