Abstract

The invention discloses a heavy-duty coating for copper. The heavy-duty coating comprises the following components in parts by mass: 100 parts of polyurethane modified epoxy resin, 10-15 parts of ethyl orthosilicate, 2-5 parts of polyvinyl butyral resin, 5-10 parts of butanol, 20-30 parts of ethanol, 18-20 parts of ethyl acetate, 1-5 parts of phosphoric acid, 15-20 parts of acetone, 1-5 parts of zinc oxide, 2-5 parts of cobalt naphthenate, 10-20 parts of cyclohexyl acrylate, 12-16 parts of butyl methacrylate and 5-10 parts of an organic silane coupling agent. The heavy-duty coating is good in water resistance and resistant to salt water, sea water, oil, corrosion and high temperature of 500-700 DEG C, can be widely produced and continuously replaces an existing material.

Description

[0001] technical field [0002] The application belongs to the field of coatings, in particular to a coating for heavy-duty anti-corrosion copper. [0003] Background technique [0004] Heavy-duty anti-corrosion coatings refer to a type of anti-corrosion coatings that can be applied in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings. They can be used under harsh conditions and have long-term anti-corrosion properties. Lifespan, heavy-duty anti-corrosion coatings can generally be used for 10 or 15 years in chemical atmospheres and marine environments, and can be used for more than 5 years even in acid, alkali, salt and solvent media and under certain temperature conditions. Filmization is an important symbol of heavy-duty anti-corrosion coatings. The dry film thickness of general anti-corrosion coatings is about 100 μm or 150 μm, while the dry film thickness of heavy-duty anti-corrosion coatings is 200 μm...
