Abstract

The invention discloses a corrosion-resistant coating for metals, which comprises the following ingredients in parts by weight: 55-65 parts of an epoxy resin emulsion, 35-45 parts of alloy powder, 20-25 parts of chlorinated polyether resin, 10-20 parts of fluororesin, 5-10 parts of cosolvents, and 20-40 parts of water. The corrosion-resistant coating has the benefits as folllows: according to the corrosion-resistant coating for the metals and the preparation method for the corrosion-resistant coating, the coating has strong adhesion force, long continuous protective time and a good protecting effect on corrosion such as acid / alkali liquid corrosion, electrical erosion and the like in the conventional production; the experiments in factories show that the utilization rate of the metals coated with the corrosion-resistant coating is increased by 30%.

Description

technical field [0001] The invention relates to the field of metal surface coatings, in particular to a metal anticorrosion coating and a preparation method thereof. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. The corrosion of metals spreads all over the national economy and brings huge losses to the national economy. In industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total output value of the national economy, the annual corroded and rusted steel accounts for about 20% of the output, and about 30% of the equipment is scrapped due to corrosion. In China, the economic loss caused by metal corrosion is as high as more than 30 billion yuan per year, accounting for 4% of the gross national product. However, there is no comprehensive coating specifically aimed at metal corrosion protection on the market today...
