Abstract
The invention relates to the technical field of powder coating, in particular to an ultralow-temperature cured epoxy powder coating and a preparation method thereof. The formula of the powder coating comprises the following components in percentage by weight: 47-65% of bisphenol A epoxy, 3-6% of organic urea curing agent, 0.2-0.5% of benzoin, 8.8-19.5% of rutile type titanium dioxide and 20-30% of precipitated barium sulfate. The ultralow-temperature cured epoxy powder coating and the preparation method thereof are applied to surface coating of thermosensitive base materials, such as plastic products, paper, paperboards, wood and the like. The ultralow-temperature cured epoxy powder coating has the characteristics of excellent mechanical performance. Meanwhile, the ultralow-temperature cured epoxy powder coating can be quickly cured and is easy to popularize and apply, production cost is lowered, and energy is saved.
