Abstract

The invention relates to the technical field of bulletproof ceramics, and discloses a preparation method of a boron carbide individual soldier plugboard ceramic. The preparation method comprises the steps of preparing the following raw materials in parts by weight: 22-43 parts of boron carbide powder, 9-15 parts of graphene, 12-22 parts of ethanol, 4-8 parts of a dispersing agent, 2-7 parts of silicon rubber, 3-9 parts of vanadium diboride, 5-7 parts of a core-shell structure polymer, 2-5 parts of a silane coupling agent and 6-11 parts of epoxy resin, and preparing a graphene suspension, specifically, dissolving a dispersing aid in ethanol to prepare a solution. According to the invention, the anti-elasticity performance and the anti-bending performance of a protection product can be improved, so that the protection performance of the protection product is improved, the prepared plugboard ceramic has ultrahigh hardness, meanwhile, the toughness of the plugboard ceramic is greatly improved, the service life of the plugboard ceramic is prolonged, and then the performance of resisting multiple bullets of the composite ceramic plate, namely, the bulletproof plugboard, can be improved.

Description

technical field [0001] The invention relates to the technical field of bulletproof ceramics, in particular to a method for preparing boron carbide single-soldier plate ceramics. Background technique [0002] More and more existing bulletproof plates use ceramics as the main body of bullet defense, such as boron carbide and silicon carbide. Compared with metal materials, ceramics have extremely high strength, light weight, and can easily withstand harsh working conditions such as strong acids, strong alkalis, and high temperatures. But everything has its two sides, and the ultra-high hardness of ceramics also brings its biggest disadvantage, brittleness (fragility). Ceramics shattered by bullets will completely lose their protective properties, posing a major threat to personal safety. Therefore, the toughening of ceramics is an important development direction of ceramics in the future, and it is also the most important technology of this type of bulletproof plate. Therefor...
