Problems solved by technology
[0003] However, traditional heavy-duty anti-corrosion coatings have technical problems such as low solid content, high solvent content, thin film formation, low adhesion, strict surface treatment requirements, complex construction technology, dew point restrictions, serious environmental pollution, and short life. When coating, the metal surface must be strictly derusted and the surface to be coated must be dry. These are the long-term problems faced by traditional heavy-duty anti-corrosion coatings.

Abstract
The invention discloses an anticorrosive coating, which is prepared from the following raw materials in parts by weight: 20-35 parts of epoxy resin 618, 10-18 parts of etherified amino resin, 5-10 parts of flaky graphite, 3-6 parts of grey mica iron oxide, 5-8 parts of aluminium oxide, 3-7 parts of tertiary amine curing accelerator, 2-6 parts of silane coupling agent, 8-15 parts of ethanol ethyl ether acetate, 3-6 parts of diluent and 7-11 parts of cellulose acetate. The diluent is one or a plurality of diacetone alcohol, cyclohexanone, ethanol, methanol, ethylene glycol or ethyl ether. The anticorrosive coating provided by the invention is strong in salt water resistance, good in weather resistance and anticorrosive property, and stronger in adhesive force and wear resistance.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion coating. Background technique [0002] Anti-corrosion coatings can be used under harsh conditions and have long-term anti-corrosion life. They are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings. They are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] However, traditional heavy-duty anti-corrosion coatings have technical problems such as low solid content, high solvent content, thin film formation, low adhesion, strict surface treatment requirements, complex construction technology, dew point restrictions, serious environmental pollution, ...
