Inorganic surface treatment galvanized steel plate and preparation method thereof

Abstract

Disclosed are an environment-friendly inorganic surface treatment galvanized steel plate and a preparation method and water-based inorganic surface treatment agent of the environment-friendly inorganic surface treatment galvanized steel plate. According to the environment-friendly inorganic surface treatment galvanized steel plate and the preparation method and water-based inorganic surface treatment agent of the environment-friendly inorganic surface treatment galvanized steel plate, progressive die rapid deep-drawing machining in the micro-motor field can be met, and excellent part anti-red-rust performance and surface conductivity are achieved simultaneously. Under an open environment, by coating and curing the water-based inorganic surface treatment agent containing a single organic silane coupling agent containing hydrophobic groups, a system crosslinking agent, water-soluble nano sol, surface modified high-density polyethylene particles, orthosilicate ester modified graphene oxide, a water-soluble fluorinated compound, a water-soluble phosphorous compound, a water-soluble metallic salt compound and the like on the surface of the galvanized steel plate, the obtained inorganicsurface treatment galvanized steel plate has excellent anti-red-rust performance, the surface conductivity, surface lubrication performance and anti-stamping blackening performance, requirements of progressive die rapid deep-drawing machining and bare service can be met, and therefore, the environment-friendly inorganic surface treatment galvanized steel plate and the preparation method and water-based inorganic surface treatment agent of the environment-friendly inorganic surface treatment galvanized steel plate are especially suitable for the field of micromotors.

Problems solved by technology

However, this steel plate is a thick-coated product with a single-layer film thickness of 2-10 microns. Its manufacturing process is a two-step method. First, a chromium-free chemical conversion film is formed, and then polyester resin is coated. It is obtained by coating twice and baking twice. Usually, the second baking is required to heat the steel plate at a temperature of 170-250°C. This patent requires relatively high production equipment and does not have surface conductivity, so it is not suitable for micro Motor field
