The invention discloses a low-gloss powder coating for hub primer, and relates to the field of powder coatings. In the application, the low-gloss powder coating for the wheel hub primer comprises the following components in parts by weight: 55-65 parts of epoxy resin; 15-25 parts of polyester resin; 0.8-1.2 parts of a leveling agent; 3-5 parts of a matting agent; 0.3-0.8 part of benzoin; 0.3-0.8 part of a degassing agent; 5-15 parts of a pigment; and 5-10 parts of filler. The powder coating is used for solving the problems that the curing temperature of an existing powder coating is generally kept at 180 DEG C or above, embrittlement of the surface of an aluminum hub is caused, the impact resistance is reduced, and the leveling property of the powder coating is reduced when the powder coating is sprayed on the surface of the aluminum hub through low-temperature curing.

    本发明公开了一种轮毂底漆用低光粉末涂料,涉及粉末涂料领域。在本申请中,一种轮毂底漆用低光粉末涂料,按照重量份计算,包括以下组分:环氧树脂55‑65份;聚酯树脂15‑25份;流平剂0.8‑1.2份;消光剂3‑5份;安息香0.3‑0.8份;脱气剂0.3‑0.8份;颜料5‑15份;填料5‑10份。本申请用于解决现有粉末涂料的固化温度通常保持在180℃以上,会导致铝轮毂表面的脆化降低抗冲击能力,而进行低温固化会导致粉末涂料在铝轮毂表面喷涂时流平性降低的问题。
