Description

technical field [0001] The invention relates to the technical field of antirust coatings, in particular to a titanium powder type antirust coating, a preparation method and an application thereof. Background technique [0002] Antirust coatings are coatings that protect metal surfaces from chemical or electrochemical corrosion of the atmosphere, sea water, etc. Coating anti-rust coatings on the metal surface can effectively prevent the direct invasion of various corrosive substances in the atmosphere, so as to maximize the extension of the metal service life. [0003] Phenolic resin is composed of a large number of benzene rings, can be cross-linked into a bulk structure, has greater rigidity and excellent heat resistance, but has defects such as high cost, dark adhesive layer color, high curing temperature and long curing time. [0004] Melamine-formaldehyde resin is a polymer obtained by the reaction of melamine and formaldehyde. Cross-linking reaction occurs during proce...
