The invention provides quick-
drying hydrophobic
lacquer and a preparation method thereof. The preparation method comprises the following steps: performing
aldehyde-
ammonia condensation on 4-
formaldehyde-2,2'-
bipyridine and aminated
nano silicon dioxide, adding a
copper salt, performing a reaction to obtain a
nano silicon dioxide supported bipyridyl Cu(II) complex, adding the
nano silicon dioxide supported bipyridyl Cu(II) complex into raw
lacquer, and performing uniform stirring to prepare a raw
lacquer composite film. According to the invention, the natural raw lacquer is utilized as a
raw material, the
nano silicon dioxide supported bipyridyl Cu(II) complex is added, so that
laccase activity is improved, the
drying time of a lacquer film is reduced, and roughness of the surface of the lacquer film is increased to make a
contact angle of the surface of the lacquer film is increased; therefore the quick-
drying hydrophobic lacquer with a fast drying speed and good hydrophobic performance is obtained. The surface of the lacquer film can be dried in half an hour, and the
contact angle reaches up to 100 degrees; and
time cost in production is greatly saved,
corrosion resistance of thelacquer film to moist
atmosphere,
acid rain,
seawater and salt spray is improved, and foundation of industrialization of raw lacquer is laid.
