5. It has the effect of conducting static electricity, but it does not have the same conductivity as conductive paint
[0007] The existing cold-sprayed zinc is mainly a one-component paint. After the paint is applied to the metal parts, compared with hot-dip galvanized and hot-sprayed galvanized metal parts, the metallic luster is poor, and it is difficult to integrate with the appearance of the original galvanized parts. one body

Abstract

The invention relates to a cold spray plating zinc and silver contained corrosion-resistant material for hot-galvanized zinc and hot-sprayed zinc reparation. The material is obtained by compounding five parts of silver powder, zinc powder, a volatile solvent, organic resin and an additive, wherein the mass fraction of the zinc powder in the corrosion-resistant material is 85%. The corrosion-resistant material can be used for reparation of corrosion and damage of surface of hot-galvanized zinc and hot-sprayed zinc, has metallic luster of galvanized zinc, has long-acting corrosion-resistant function on the galvanized zinc after being constructed, has super-strong metallic lustrousness, and has the appearance effect of being integrated with an original galvanized zinc part. A method provided in the invention is simple and feasible.

Description

technical field [0001] The invention belongs to the field of anti-corrosion material manufacturing, and in particular relates to an anti-corrosion material used for hot-dip galvanizing and hot-spraying zinc repair. Background technique [0002] Hot-dip galvanizing, also called hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. Hot-dip galvanizing is to immerse the rust-removed steel parts in the molten zinc at about 500 ° C, so that the surface of the steel components will be attached with a zinc layer, thereby playing an anti-corrosion role. Hot-dip galvanizing process: pickling of finished products - water washing - adding auxiliary plating solution - drying - rack plating - cooling - chemical treatment - cleaning - polishing - hot galvanizing - completion. Hot-dip galvanized products have been applied to many fields. The advantages of hot-dip galvanized are long-term a...
