The invention discloses an environment-friendly anticorrosive
coating material for automobile parts and a preparation method thereof. The environment-friendly anticorrosive
coating material comprises an ingredient A and an ingredient B, wherein the ingredient A comprises
epoxy resin,
pigment / filler, auxiliaries and an
organic solvent, and the ingredient B comprises
polyamide resin, a
siloxane compound, a
tertiary amine curing accelerator and an
organic solvent. According to the anticorrosive
coating material disclosed by the invention, the construction
solid content is high (not lower than 60wt%), the VOC (
Volatile Organic Compound) emission is low during construction, and the construction performance and
film coating property are excellent; the coating material can be applied to anticorrosive coating
layers of automobile
metal parts, such as transmission cases,
chassis parts, axles and other castings, the coating supporting is simple, the requirements on substrate pretreatment are low, sandblasting and phosphating treatment are not required, and good
film coating performance can be guaranteed by only cleaning and
degreasing; and the environment-friendly anticorrosive coating material for the automobile parts, disclosed by the invention, is simple in preparation process and is energy-saving and environment-friendly, and the prepared product is stable in performance.
