Dryer for coating

The invention relates to the technical field of a coating and especially relates to a dryer for the coating. The dryer for the coating comprises the following components in parts by weight: 50-70 parts of isocaprylic acid, 10-15 parts of vanadium pentoxide, 20-30 parts of aromatic solvent oil, 10-15 parts of rare earth compound, 10-15 parts of carbonate and 10-15 parts of nickel compound. The dryer for the coating provided by the invention can be applied to an aromatic hydrocarbon solvent and an aliphatic hydrocarbon solvent, can be used for replacing the application of the traditional mixed metal of cobalt, manganese, lead, zinc and calcium as the dryer in a coating industry and can be added into the coating at one time; the dosage is only 10% of the dosage of the traditional dryer; and the dryer for the coating has the characteristics of less dosage, obvious economic benefit, convenience in use and convenience in management. 本发明涉及涂料技术领域，尤其涉及种涂料用催干剂。该种涂料用催干剂以质量份计：异辛酸50-70份、五氧化二钒10-15份、芳烃溶剂油20-30份、稀土化合物10-15份
