[0024] A preparation method of pure epoxy fast-curing powder coating, the method may further comprise the steps:
[0025] a. Add 52% to 57% of epoxy resin, 2% to 3% of curing agent, 0.1% to 1% of curing accelerator, 0.1% to 0.4% of benzoin, 0.7% to 1.4% of imported leveling agent, and 0.4% of castor oil ~1.0%, colorant 5%~10%, antioxidant 0.3%~1.2%, precipitated barium sulfate 28%~35% are mixed in a container according to the proportion, and mixed evenly;
[0026] b. After the mixed material in step a is extruded-tablet-crushed, the finished product is obtained.
[0030] The above raw materials are mixed according to the proportion, extruded, pressed into tablets, crushed, and then sprayed on the metal workpiece. Curing conditions: 200°C / 3min.

Abstract
The invention relates to the technical field of quickly curing powder coating, in particular to a pure epoxy quickly-cured powder coating and a production method thereof. The powder coating contains the following compounds according to percentages by weight: 52-57wt% of epoxy, 2-3wt% of curing agent, 0.1-1wt% of curing catalyst, 0.1-0.4wt% of benzoin, 0.7-1.4wt% of inlet flatting agent, 0.4-1.0wt% of castor oil, 5-10wt% of pigment, 0.3-1.2wt% of antioxidant and 28-35wt% of blanc fixe. Due to special curing catalyst and curing agent, the coating has high curing speed, and the impact resistance of the coating is guaranteed simultaneously.
Description
technical field [0001] The invention relates to the technical field of fast-curing powder coatings, in particular to a pure epoxy fast-curing powder coating and a preparation method thereof. Background technique [0002] Powder coating is widely used in the surface coating of various metal parts due to its environmental protection and economic superiority. In recent years, with the environmental protection characteristics of powder coatings, the application fields have been expanded; at the same time, the requirements for curing conditions of powder coatings are also getting higher and higher. [0003] Generally, the curing conditions of powder coatings are mostly high baking temperature and long baking time, which causes a waste of energy. Therefore, from the perspective of saving energy, reducing costs and improving production efficiency, fast-curing powder coatings have broad market prospects. Contents of the invention [0004] In order to overcome the shortcoming of ...
