Partial plating method of automobile resin part and automobile resin part plated by using the same

A partial plating method of an automobile resin part, including:

• a painting step of partially applying masking paint for plating on one side surface of an injection molded automobile resin product to form a painting portion where the masking paint for plating is applied and a non-painting portion where the masking paint for plating is not applied;
• and
• a wet electroplating step of attaching a current electrode for wet electroplating on the non-painting portion and performing the wet electroplating to form a plating layer on an entire surface of the automobile resin part except for the painting portion,
• wherein the masking paint for plating contains a masking resin composition for plating, the masking resin composition for plating contains a polymer resin, an organic solvent, a plasticizer, and an inorganic additive, and
• wherein the polymer resin is a mixture of poly vinyl chloride (PVC) and an ethylene-vinyl acetate copolymer (EVA), and
• wherein the plasticizer is trioctyl benzene-1,3,5-tricarboxylate, and
• wherein the organic solvent includes methyl isobutyl ketone, toluene, n-butanol, and ethyl acetate, and
• wherein the inorganic additive includes sodium (Na), aluminum (Al), potassium (K), calcium (Ca), titanium (Ti), and iron (Fe).
