Abstract

The invention provides an epoxy polyester type pearlescent powder coating. The epoxy polyester type pearlescent powder coating comprises the following components in parts by weight: 30-35 parts of epoxy resin, 30-35 parts of polyester resin (acid value is 70-85mgKOH / g), 1-1.5 parts of a levelling agent, 15-20 parts of a filler, 1-1.5 parts of additives, 0.3-0.4 part of special auxiliaries, 0.5-1.0 part of common pigment, 3.5-4.0B of pearlescent pigment 9240(%). The epoxy polyester type pearlescent powder coating has strong decorative property and is obvious in pearlescent effect, and utilization rate of pearlescent pigment is high; meanwhile, only does one-time electrostatic coating need to be carried out, so that construction is convenient.

Description

technical field [0001] The invention relates to a powder coating, in particular to an epoxy polyester type pearlescent powder coating. Background technique [0002] Powder coating is a new type of solvent-free, 100% solids powder coating. It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. It has two categories: thermoplastic powder coating and thermosetting powder coating. Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coatings include: epoxy resin, polyester, acrylic resin. [0003] Disadvantages: uneven po...
