Objective In order to reduce the damage to electronic products around or inside of aluminum-base metal packaging material by electrostatic discharge. Methods The principle of the triboelectrification between metal packaging material and space particles was theoretically analyzed and a calculation formula for triboelectrification potential was deduced based on solid contact separation electrification. To verify the theoretical analysis, an aluminum-base metal material was used as an example to study the triboelectrification. Results The theoretical deduction found that the electrostatic potential of the material increased in a negative exponent manner with time, and tended to be saturated gradually. The saturation value was related with the properties of the material, and was positively correlated with the friction speed and the contact area. In the material triboelectrification potential test, the variation curve of electrostatic potential was the same as the theoretical analysis results. And the electrification potential in continuous test decreased gradually. The variation of the electrostatic potential saturation values of different materials and different friction speeds verified the relationship between the triboelectrification potential of metal material and the friction coefficient of the material as well as the contact area. Conclusion The increasing rule of the triboelectrification potential was obtained through theoretical analyses and material triboelectrification experiment, which provides guidance for the reduction of electrostatic damage.
