Abstract

The invention discloses an antiriot helmet and a preparing method thereof. The antiriot helmet comprises an inner helmet body and an outer helmet body arranged on the inner helmet body in a sleeving mode. The inner helmet body and the outer helmet body are attached together through an adhesive. The outer helmet body is prepared through injection molding after melting of PC / ABS alloy aggregates. The inner helmet body is prepared through molding of multiple layers of aramid fiber fabric layers dipped with modified phenolic resin. The antiriot helmet effectively resists the attacks of bullets, edge tools, clubs, non-explosive projectiles and chemical liquid and effectively protects the head, face and neck of a human body.

Description

technical field [0001] The invention relates to the technical field of military helmets, in particular to an anti-riot helmet and a preparation method thereof. Background technique [0002] Anti-riot helmets are the protective equipment that individual soldiers must wear in the process of performing anti-riot tasks, and have always been valued by the armies of various countries. Anti-riot helmets are mostly made of metal materials and are used to resist the attacks of sharp weapons, sticks, non-explosive projectiles and chemical liquids, so as to effectively protect the head, face and neck of the human body. Now under the new anti-terrorism and anti-riot situation, the Equipment Development Department of the Central Military Commission has put forward higher requirements for anti-riot helmets, requiring anti-riot helmets to have a certain bullet-proof function, that is, to protect the 97-1 shotgun from launching the 97-type 18.4mm Capability of killing bullets. [0003] At...
