Problems solved by technology

If the viscosity is too high, although the coating amount increases, the fluidity becomes poor, which is not ideal for the first coating process; if the viscosity is too low, the fluidity is good, but the coating amount is reduced

Abstract

The invention discloses a self-leveling and self-repairing zinc-aluminum paint, a preparation method and application thereof. The paint is a mixture mainly prepared by compounding nanoscale flaky zincpowder and floating flaky aluminum powder with a lubricant, an anti-settling agent and a coupling agent and performing dissolution in deionized water, wherein the mixture is added with inorganic silicon, an alcohol solvent, an active agent and the like in proportion. The zinc-aluminum paint disclosed by the invention has high solid content and low viscosity, can reach an ideal coating effect, andhas good self-leveling effect, a coating formed by coating of the paint on a metal workpiece is uniform in appearance, free of holiday and high in covering rate, the coating is free of red rust after480 hours of neutral salt spray test, has good antirust and corrosion-resistant effects, and has excellent adhesive force, good adhesion with other additional coatings and superior recoating performance.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a self-leveling and self-repairing zinc-aluminum coating and a preparation method and application thereof. Background technique [0002] Dacromet coating is also called zinc chromium coating, which is a new surface treatment technology that has developed rapidly in my country in the past ten years. Its characteristics are: excellent corrosion resistance; coating thickness 5-8 microns; neutral salt spray test can basically reach more than 480 hours without red rust, which cannot be achieved by electro-galvanizing; no hydrogen embrittlement; Contaminated waste water discharge. Due to the above obvious advantages, it is gradually replacing the electro-galvanizing process. However, Dacromet coating also has obvious shortcomings. In addition to the conventional coating surface hardness is not high, acid and alkali resistance, single appearance color, there is an obvi...
