Description
Technical field
The present invention relates to Antiballistic shaped part preparation field, more particularly to a kind of system of ultra high molecular weight polyethylene bulletproof helmet
Preparation Method.
Background technology
Traditional bulletproof halmet is made of metal mostly, this helmet not only heavy, and easily causing after being hit by a bullet
Secondary fragment injures.At present, in the market gradually adopts high-performance fiber compacting bulletproof halmet to carry out the shellproof helmet of substituted metal.
Superhigh molecular weight polyethylene fibers are a kind of high-strength high-modulus fibres, and density is less than water, and its fiber UD materials are near
A kind of novel light high-performance composite materials occurring on year international market, being mainly used in advanced ballistic area, it is also referred to as poly-
Ethene UD laminated cloths.The bulletproof halmet suppressed using polyethylene UD laminated cloths has barrier propterty height, light weight, and can prevent two
The advantages that secondary fragmentation injury.
Existing high-performance fiber bulletproof halmet production process, is concentrated mainly in same open die and completes, pressure
Cut again with sawtooth along helmet shell edge after making.So easily produce two disadvantageously：On the one hand, it is general because cutting
By the way of artificial, the comparison of coherence that helmet edge may be caused to cut is poor, and on the other hand, polyethylene UD laminated cloths are being cut out
If method is improper easily to cause edge delamination during cutting, ballistic performance is influenceed.
In addition, the existing shellproof PE helmets come protection helmet shell and meet client to helmet typically by the way of surface coating paint
The requirement of shell color, although helmet shell has been gone in coating paint advance sandblasting and strikes off processing, due to the inertia of PE materials in itself,
The adhesiveness of itself and paint or very poor, during in particular by hitting or fall, easily cause lacquer painting to come off, influence outside the helmet
See.Meanwhile the paint of surface coating dries the regular hour needed, typically at least needs more than 24 hours, influences helmet system
The standby time.
The content of the invention
It is an object of the invention to solve above-mentioned deficiency, there is provided a kind of bulletproof halmet and preparation method thereof, using poly- second
Alkene fiber laid fabric and polyethylene fiber woven cloth, not only alleviate the weight of the helmet, moreover it is possible to prevent secondary fragment from injuring；Simultaneously
The technique that traditional coating paint is replaced using the spraying of novel environment friendly polyurea elastomer material, is shortened spraying drying time, carried
The effects such as high the wear-resisting of bulletproof halmet, anticollision, damping and durability.
The present invention also provides a kind of preparation method of above-mentioned bulletproof halmet, comprises the following steps：
Step 1, superhigh molecular weight polyethylene fibers UD laminated cloths are cut, intersect the lamination for being positioned over no heating system
