Inorganic water-based silicate sealing reagent used in high velocity arc spray at high temperature is prepared and investigated in this paper.

The permeability-increasing agent ZSJ of silicate complex material was prepared by compounding GS material and inorganic substance MD.

The multifunctional waterproof binder is made from silicate cementing material as base material, filler, active water-repellent material, compound binder, assistant and so on.
