Medium-and-low temperature cured thinly-coated powder coating for household electrical appliance and preparation method for medium-and-low temperature cured thinly-coated powder coating

The invention discloses a medium-and-low temperature cured thinly-coated powder coating for a household electrical appliance and a preparation method for the medium-and-low temperature cured thinly-coated powder coating, and belongs to the technical field of coatings. The medium-and-low temperature cured thinly-coated powder coating is prepared from end carboxyl polyester resin, epoxy resin E-12, a flatting agent, a de-foaming agent, a low-temperature curing agent, a pigment and a filler by mixing at a high speed in a high-speed material mixing cylinder, extruding from a screw extruder, performing graded grinding in an ACM pulverizer and screening. According to the medium-and-low temperature cured thinly-coated powder coating for the household electrical appliance and the preparation method for the medium-and-low temperature cured thinly-coated powder coating, the medium-and-low temperature cured powder coating is prepared by adopting the raw materials which are in reasonable ratio according to a charging sequence limited by the invention; a variety of different colors can be generated by coating the medium-and-low temperature cured powder coating on the household electrical appliance; the medium-and-low temperature cured powder coating has a special strong shining effect, has high adhesion force, high-temperature resistance, and high heat conductivity, and is cured at a medium-and-low temperature; the medium-and-low temperature cured powder coating is coated moderately or thinly (150 DEG C/10 to 15 minutes); the thickness of a film is 10 to 50 mm; the current market demand is met; the quality of a product is guaranteed; the energy is saved; moreover, the using cost of a household electrical appliance manufacturer is reduced.
