Description

technical field [0001] The invention discloses a long-acting water-based metal heat-insulating and anti-corrosion coating, which belongs to the technical field of polymer materials. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, 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] The anticorrosion principle of general anticorrosion coatings lies in the direction of chemistry, physics and electrochemistry. The following is a detailed explanation: the chemical principle of anticorrosion is to neutralize harmful acid and alkali substances into neutral and harmless substances to protect the materials i...
