Problems solved by technology

However, because the volume concentration of zinc powder far exceeds that of CPVC, the binder is not enough to fill the gaps between the coatings, thus forming a porous coating structure, and the anti-corrosion performance decreases instead.

Abstract

The invention discloses an anti-corrosion material capable of substituting electroplated zinc and a preparation method of the anti-corrosion material. The anti-corrosion material capable of substituting electroplated zinc comprises the following components in percentage by weight: 60-90% of zinc powder, 1-10% of organic resin, 0.2-2% of an anti-settling agent, and 5-30% of an organic solvent. The invention further discloses a preparation method of the anti-corrosion material capable of substituting electroplated zinc. The anti-corrosion material capable of substituting electroplated zinc provided by the invention is convenient to construct, has excellent anti-corrosion performances, and is environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to an anti-corrosion material which can replace electro-galvanizing and a preparation method thereof, in particular to a single-component pasty material which can replace electro-galvanizing and a preparation method thereof. Background technique [0002] Steel can easily rust or even be completely damaged when exposed to air, water or soil. Annual steel consumption due to corrosion accounts for about 1 / 10 of the entire steel production. Because zinc is not easy to change in dry air, but in humid air, a very dense basic zinc carbonate film can be formed on the surface, which can effectively protect the internal zinc from being corroded, and when the protective layer is damaged When a not too large steel base is exposed, the zinc and the steel base form a micro-battery, making the steel base a cathode and protected. Based on the above principles, at present, electrogalvanizing is generally used for corrosion protection of steel. ...
