Abstract

The invention relates to ultralow temperature cured powder paint, which belongs to the technical field of powder paint. The ultralow temperature cured powder paint has the characteristic that an ultraviolet light initiator and an infrared absorbent are added in the powder paint. An infrared and ultraviolet dual-curing mode is adopted for the ultralow temperature cured powder paint disclosed by the invention, the curing temperature is low, the curing time is short, the curing is complete, and a cured powder coating has the characteristics of the excellent chemical resistance, good adhesive force, poaching endurance and yellowing resistance. The infrared curing and the ultraviolet curing complement each other, and highlight advantages, and the rapid ultralow temperature curing of the powder paint is realized.

Description

technical field [0001] The invention relates to an ultra-low temperature curing powder coating and an application method thereof, belonging to the field of powder coatings. Background technique [0002] China's annual output of wood-based panels is about 30 million cubic meters. If calculated according to the thickness specification of 16mm panels, the annual output of wood-based panels will reach 1.8 billion square meters. In recent years, with the continuous development of powder coating technology and the large demand for powder coating wood-based panels, it has attracted more and more attention from many wood processing enterprises. In addition to the well-known advantages of powder coatings such as zero VOC content, the powder coating of wood-based panels also imparts good adhesion to the coated substrate, excellent scratch resistance and stain resistance of the coating, and imparts various colors and effects to the coating. , Almost 100% utilization rate and efficient...
