Description

Bulletproof halmet and preparation method thereof
Technical field
The present invention relates to bulletproof equipment technical field, it is specifically designed a kind of bulletproof halmet and preparation method thereof.
Background technique
Bulletproof halmet is not only applicable to army, but also answer extensively as the individual soldier protection equipment for making head escape injury For finance, tax revenue, customs preventive and other need explosion-proof field.Bulletproof halmet can absorb the kinetic energy of dissipation bullet, Prevention penetrates, and effectively resists bullet, elastic slice and other injuries of the strike object to head, effective protection wearer head and reduce by Casualty rate caused by stray bullet.
In modern protective gear, superhigh intensity fibrous composite, which is just gradually replacing metal, becomes the shellproof material of a new generation Material.Superhigh intensity fibrous composite is different from metal material on bullet-proof mechanism, largely absorbs energy when using itself fracture Amount, and transmit energy quickly to prevent elastic slice from penetrating, compared to very stiff and demanding metal material, belong to the protection form defeated a force with a tenderness. The ultra high molecular weight polyethylene fiber the most frequently used at present, bulletproof effect is best, anti-tunnelling effect is good, but rigidity and stiffness are not so good as Metal material, thus it is easily-deformable, be hit by a bullet after cup depth it is larger.
Chinese patent CN201710795700.8 " graphene bulletproof halmet " is prepared by three-layer sandwich structure, and sandwich layer is carbon Graphene, silicon carbide and aluminium alloy, are specifically mixed into opening by the sponge structure complex of SiClx, graphene and aluminium mixing enhancing In the polyurethane sponge of hole, thus reduces helmet quality and provide sufficient elastic deformation space for graphene, significantly improve this The ballistic performance of the helmet.But the graphene bulletproof halmet complex manufacturing technology, be unfavorable for industrialization, and it is integrated by The bulletproof halmet of superhigh intensity fibrous composite preparation should not be dressed, if it is considered that comfortable wearing is convenient can not then to protect well Protect the face and lower jaw of wearer, it is therefore desirable to which structure and material to existing bulletproof halmet make further improvement.
Summary of the invention
The invention solves first technical problem be in view of the above shortcomings of the prior art, to provide a kind of impact resistance Can be high, the mechanical property and ballistic performance of the helmet, lighter weight and the convenient bulletproof halmet of comfortable wearing can be effectively improved.
The invention solves second technical problem be in view of the above shortcomings of the prior art, to provide and a kind of simply may be used It leans on, is easy to the method for preparing bulletproof halmet of industrialization production.
The present invention solves technical solution used by above-mentioned first technical problem are as follows: a kind of bulletproof halmet, including front end Face has the helmet body of opening, which is equipped with the first mask and the second mask, the first mask and second First side of mask is rotatably connected on the two sides of helmet body front end face opening respectively, and it is empty that second side of the second mask is equipped with the first card The eyepiece gap 4 for accommodating goggles 40 is collectively formed in gap 34, first gap 24 and Second gap 34；The eyepiece gap 4 Periphery be equipped with slot 41, the surrounding of goggles 40 is plugged in the slot 41, and the goggles 40 is by bulletproof glass system At.In this preferred embodiment, the outer rim of goggles 40 be set as adaptation pyramidal structure, goggles 40 can with the first mask 2 or Second mask 3 is locked, and goggles 8 need to be only inserted into the slot of another mask by when wearing, in order to dress.
