The nanoscale aqueous heavy-duty self-cleaning coating comprises the following components in parts by weight: 43 parts of ethanol, 4 parts of ammonium salt dispersant, twelve 11 parts of alcohol ester, 10 parts of nano titanium dioxide, 9 parts of flatting agent, 18 parts of ethylene glycol, 5 parts of bentonite, 5 parts of hydroxyethyl fiber, 28 parts of acrylic resin, 42 parts of zinc powder, 15 parts of nano silicon dioxide, 9 parts of benzene auxiliary agent and 6 parts of flash rust inhibitor.
The nano-scale aqueous heavy-duty self-cleaning coating prepared in examples 1 to 4 is compared with a common aqueous heavy-duty coating:
as can be seen from the contact angle test report in the figure, the contact angle is 10 degrees, which is seen to be much smaller than that of the common coating.
Therefore, compared with the common water-based heavy-duty anticorrosive self-cleaning coating, the nano-scale water-based heavy-duty anticorrosive self-cleaning coating has the advantages of good corrosion resistance, pressure resistance, tough coating film, impact resistance, dust resistance, oil stain resistance, pollutant degradation performance and air purification performance.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
