Problems solved by technology
The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art. In order to solve the problems of corrosion resistance of inorganic zinc coatings such as electro-galvanizing, hot-dip galvanizing and Dacromet coating, a silver-aluminum polymer top coating is provided. Coating and preparation method thereof, this silver-aluminum polymer top-coat coating is the top-coat coating with flake metal aluminum powder as the core, which can greatly reduce the porosity of the paint film, and can be used as Dacromet coating, electrogalvanizing and The top coating of hot-dip galvanizing doubles the salt spray corrosion resistance life of Dacromet coating, and increases the salt spray corrosion resistance life of electro-galvanized and hot-dip galvanized by eight times. It is suitable for application in various corrosive environments such as acid and alkali. Also improves the wear resistance of the coating

Abstract
A silver-aluminum polymer top coating and its production are disclosed. The coating consists of flake aluminum power, modified epoxy resin, diluting agent, anti-settling agent and dispersant. The process is carried out by taking superfine flake dry aluminum powder, adding into diluting agent, wetting, dipping at normal temperature and pressure, mixing while agitating, or taking superfine flake solvent aluminum powder slurry, adding into diluting agent, mixing while agitating, adding into modified epoxy resin and residual diluting agent at normal temperature and pressure, adding into anti-settling agent and dispersant, and agitating to obtain final product. It has less porosity rate and can reach to Chrol coating, electroplating zinc and hot-dipping zinc top coating, and have better salt-fog corrosive resistance and abrasive performance.
Description
technical field The present invention relates to a kind of top coating paint and its preparation method, especially to a kind of silver-aluminum polymer top coating paint and its preparation for improving the corrosion resistance of inorganic zinc coatings such as electrogalvanizing, hot-dip galvanizing and Dacromet coating method. Background technique At present, traditional electro-galvanized, hot-dip galvanized and Dacromet coatings and other inorganic zinc-coated zinc-rich coatings generally have problems such as unsatisfactory corrosion resistance life and low surface scratch resistance.
