Anticorrosive paint for copper

Abstract

The invention discloses an anticorrosive paint for copper, which is prepared by stirring the following raw materials in parts by weight: 80-85 parts of epoxy resin, 20-25 parts of polystyrene resin, 10-15 parts of 424 resin, 10-14 parts of silicon dioxide emulsion, 8-16 parts of dimethylbenzene, 3-9 parts of isobutyl acetate, 4-6 parts of polybenzimidazole, 8-10 parts of KH-560, 10-14 parts of talcum powder, 3-7 parts of tributyl phosphate, 6-8 parts of cobalt oxide, 11-14 parts of sodium petroleum sulfonate and 50-70 parts of water. The commercial test proves that the prepared paint has the advantages of excellent water resistance and excellent corrosion resistance, can implement passivation and corrosion inhibition of the metal substrate, avoids using chrome and other heavy metals capable of causing environmental pollution, is simple to prepare and low in cost, and can being easily put into industrial production.

Description

technical field [0001] The invention relates to an anticorrosion coating for copper materials, which belongs to the technical field of chemical coatings. technical background [0002] At present, the annual economic losses caused by metal corrosion in my country account for about 3-5% of the gross national product, and the losses exceed the sum of the losses caused by fire, wind disasters and earthquakes. For a long time, in order to reduce the loss of corrosion, people have taken many measures, such as electrochemical protection of metals, corrosive medium treatment, overlay protection and so on. But so far the most common, economical and practical protection measures are coating protection. Coating anti-corrosion is widely used because of its simple construction, economical applicability, no constraints on equipment area and shape, and certain decorative effects. [0003] Copper metal material is a metal material that is widely used in various fields, and it is also a me...

Problems solved by technology

At present, most of the anti-corrosion coatings applied on the surface of copper in the market are solvent-based coatings, and many of these coatings have no obvious anti-corrosion effect; while the remaining coatings have the effect of inhibiting corrosion, but due to They contain harmful gases and heavy metals that are easy to cause damage to the human body, causing environmental pollution problems. At the same time, the characteristics of flammable and explosive solvents have brought unsafe hidden dangers to the environment.
