Novel vacuum sealing material composition

The invention relates to a novel vacuum sealing material composition which comprises a binder, wax, base oil and an additive. A preparation method comprises the steps of: putting the filtered binder, the refined wax, the base oil subjected to reduced pressure distillation, and the additive in a blending container, heating, starting stirring to ensure that materials are completely dissolved and uniformly mixed, heating, performing high-temperature curing, then performing vacuum degassing, and packaging when being in a hot state after filtering. The novel vacuum sealing material composition is a semi-permanent or permanent vacuum leakage stoppage material special for a vacuum system joint, system leakage stoppage, a ground joint in a glass vacuum system, or a metal pipeline, can also be used as a shielding protective agent for corrosion of a silicon sheet, and is an optimal semiconductor mesa modeling corrosion protective agent. The novel vacuum sealing material composition has the advantages of good sealing pr
