| description | The invention relates to a powder coating for a high-toughness spring and a preparation method of the powder coating. The powder coating is prepared from the following components in parts by mass: 120-270 parts of epoxy resin; 10 to 100 parts of a phenolic curing agent; 1-5 parts of an imidazole curing agent; 1-20 parts of a phenol type phenolic aldehyde curing agent; 50 to 200 parts of a functional filler; and 1-10 parts of pigment. The powder coating for the high-toughness spring has excellent corrosion resistance, damp heat resistance, salt mist resistance, water resistance, bending resistance and the like, so that the effect of completely isolating the spring from the outside is achieved; and meanwhile, the powder coating has extremely high adhesive force performance with the spring and can be stably attached to the spring workpiece, so that the spring workpiece is subjected to corrosion resistance in a long time, and the effect of maintaining the elastic force performance of the spring is achieved.
