Description

Ultra-high molecular weight polyethylene fiber composite bulletproof plugboard Technical Field The utility model relates to the field of bulletproof plugboards, in particular to an ultra-high molecular weight polyethylene fiber composite bulletproof plugboard. Background The bulletproof plugboard is used as a core component of individual protective equipment, the materials and the performances of the bulletproof plugboard directly influence the protective effect, the existing bulletproof plugboard is matched with the bulletproof clothes and is fixed in a slot of the bulletproof clothes, the bulletproof plugboard provides higher bulletproof capacity for the bulletproof clothes, although the bulletproof plugboard plays an important role in individual protection, the traditional steel plate material has excessive weight and severely limits tactical maneuverability, the bulletproof plugboard made of polyethylene material is developed, the quality is lighter, but the protection grade is limited to be NIJIII levels at most, meanwhile, the bulletproof plugboard made of ceramic has strong bulletproof capacity and light weight, but fails after middle bullets and cannot resist secondary middle bullets. The relationship between the weight and the bulletproof capacity is difficult to balance between bulletproof plugboards of various materials in the prior art, so that satisfactory bulletproof effect and lighter weight cannot be achieved; The ultra-high molecular weight polyethylene fiber composite bulletproof plugboard is provided for the purpose. Disclosure of utility model The present utility model has been made in view of the above-mentioned problems occurring in the prior art. Therefore, the utility model aims to solve the technical problem that the prior art is difficult to balance the relation between the weight and the bulletproof capacity. In order to solve the technical problems, the utility model provides the following technical proposal that the ultra-high molecular weight polyethylene fiber composite bulletproof plugboard comprises a protection component and a protection component wrapped in the protection component, The protection component comprises a wrapping cloth layer, wherein a plastic shell is wrapped in the wrapping cloth layer; The protection component comprises a metal bulletproof structure, a polyethylene structure is arranged on one side of the metal bulletproof structure, a ceramic structure is arranged on one side of the polyethylene structure, and the metal bulletproof structure, the polyethylene structure and the ceramic structure are wrapped in a plastic shell. As a preferable scheme of the ultra-high molecular weight polyethylene fiber composite bulletproof plugboard, the metal bulletproof structure comprises a metal bulletproof plate, four groups of rivet grooves are formed in the metal bulletproof plate, and rivets are installed on each group of rivet grooves in a connecting mode. As a preferable scheme of the ultra-high molecular weight polyethylene fiber composite bulletproof plugboard, the polyethylene structure comprises a polyethylene bulletproof plate, wherein the outer surface of the polyethylene bulletproof plate is coated with a waterproof coating, and the outer surface of the waterproof coating is wrapped with a heat insulation layer. As a preferable scheme of the ultra-high molecular weight polyethylene fiber composite bulletproof plugboard, the ceramic structure comprises a ceramic bulletproof plate, wherein the outer surface of the ceramic bulletproof plate is coated with a polyurea coating, and the outer surface of the polyurea coating is wrapped with a mounting cloth layer.
