[0021] As shown in the figure, a preparation method of a gun-fired rubber kinetic energy bullet includes the following steps: S1: raw material preparation, selecting outer covering material and kinetic energy bullet body material; S2: adding the kinetic energy bullet body material into a hot melt machine, adding auxiliary material compounding agent and stirring to obtain hot melt rubber; S3: preparing a mold, adding the hot melt rubber obtained in S2 into the mold, heating and pressurizing, and fully filling to form a hemispherical outer shell; S4: repeating step S3 to obtain the outer shell, inner sphere, and outer sandwich shell of the kinetic energy bullet; S5: taking the hemispherical outer shell and the inner sphere obtained in S4 and bonding them to form a hollow rubber ball with an axial ball; S6: filling an air bag to the outer surface of the hollow rubber ball, and bonding the outer sandwich shell to the outer surface of the hollow rubber ball; S7: coating the hollow rubber ball with an outer covering; S8: packaging and storing the rubber kinetic energy bullet after quality inspection.
[0022] In the specific implementation of the present invention, the outer covering material is made of PTFE material, so it is easy to form a smooth spherical surface for use, and the kinetic energy bullet body material is made of rubber material with good wear resistance and corrosion resistance, and can also be used for energy buffering. The filling airbag is made of plastic material, and is filled with independently packaged reactants A and reactants B. When reactants A and reactants B come into contact, gas expansion is generated. For example, sodium sulfide and oxalic acid are combined.
[0023] In one embodiment:
[0024] The outer wall of the shell and the outer wall of the inner sphere are both protruded with a plurality of connecting contacts, through which the connecting contacts are convenient for connecting and using each independent structure. The auxiliary materials in S2 include plasticizers, stabilizers and pigments. Rubber balls of different colors can be produced according to different usage requirements.
[0025] When coating the outer body, S7 includes cleaning the outer wall of the kinetic energy bullet, coating the outer wall of the kinetic energy bullet with a coupling agent, mixing the PTFE electrophoretic liquid, and then sending the kinetic energy bullet into the electrophoretic pool for electrophoretic coating. By electrophoretically coating PTFE, a uniform and dense PTFE coating can be formed on the surface of the rubber ball, thereby improving the corrosion resistance, wear resistance and non-stickiness of the rubber ball, ensuring smooth use of the sphere and improving the stability of the projectile during launch and flight. The quality inspection in S8 includes flight speed, flight stability and striking force tests.
[0026] In actual use, the kinetic energy bullet is a large-diameter single hollow spherical structure. The diameter of the sphere is determined according to actual needs, generally between 10-40mm, to ensure sufficient kinetic energy transfer and effective area when hitting the target. The projectile is made of rubber material, which has good elasticity and cushioning properties, and can effectively reduce damage to the target.
