The invention discloses water-proof and weather-proof
powder coating. The water-proof and weather-proof
powder coating is prepared from the following raw materials including, by weight, 42-55 parts of
drying oil
alkyd resin, 16-23 parts of
polyamide polyamine epoxy chloropropane resin, 2.5-3.8 parts of
disteardimonium hectorite, 7-9 parts of
sericite powder, 1-2 parts of azodiisobutyronitrile, 2-3 parts of
sodium lignin sulfonate, 1-3 parts of trimethyl hexamethylene
diamine, 1-2 parts of coumarone-
indene resin, 0.1-1 part of organic
silicone quaternary ammonium salt and 5-8 parts of composite fillers. Meanwhile, the invention provides a preparation method for the water-proof and weather-proof
powder coating. The water-proof and weather-proof
powder coating provided by the invention is high in transparency and good in
dispersity. The water-proof and weather-proof
powder coating can be applied to durable protective decoration industry such as factory equipment and facility, aluminum
curtain wall and television emission
tower coating through excellent water-proof, weather-proof and high-decorative properties thereof and can also be widely applied to the fields of building materials such as bridges,
doors and windows, enclosures and domestic tinting materials.
