Problems solved by technology

Zinc and aluminum oxidize in the air to produce a dense protective film - zinc oxide and aluminum oxide, so zinc and aluminum are often used as protective coatings on the surface of objects in the prior art to prevent objects from being oxidized. During the electroplating process Blue and white zinc is often chosen as the protective coating. Local damage to the surface of the object often causes the protective coating to fail, resulting in local corrosion of the metal of the object itself or local aging of the plastic. maintenance is very important

Abstract

The invention discloses a blue white zinc self-spraying healant which is prepared as follows: sending diisopropyl peroxydicarbonate into a N, N-dimethyl formamide solution with a concentration of 73.5-77.62% for evenly mixing to obtain a material A; sending trifluoroethyl methacrylate, methyl acrylate, butyl acrylate and acrylic acid into the material A for reaction for 2-4h to obtain a material B; stirring for 20-30min for dispersing a solvent comprising carbon tetrachloride, xylene and 200 # solvent oil and the material B by use of a frequency conversion dispersion kettle to obtain a material C; adding environmentally-friendly special aluminum powder and environment-friendly special zinc powder into the obtained material C for stirring and dispersing for 20-30min to obtain the blue white zinc self-spraying healant. The blue white zinc self-spraying healant has excellent moisture resistance, chemical resistance, corrosion resistance, and physical and mechanical properties, good lustrousness and light and color retention performance, and fast drying speed.

Description

technical field [0001] The invention relates to the technical field of repairing protective coatings, in particular to a blue-white zinc self-spraying type repair agent. Background technique [0002] Objects are prone to oxidation when exposed to the air, and a protective coating is often added to the surface of the object. The oxidation of zinc and aluminum in the air produces a dense protective film—zinc oxide and aluminum oxide. Therefore, in the prior art, zinc and aluminum are often used as protective coatings on the surface of objects to prevent objects from being oxidized. During the electroplating process Blue and white zinc is often further selected as the protective coating. Local damage on the surface of the object often causes the protective coating to fail, resulting in local corrosion of the metal of the object itself or local aging of the plastic. Maintenance is very important. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems exis...
