Abstract

Printing ink for pens is composed of the following raw materials (by weight): 30-45 parts of activated carbon black, 20-30 parts of calcene, 1-3 parts of tetrafluoro isoindolinone, 30-40 parts of a binder, 1-4 parts of linolenic acid oil, 2-3 parts of 2-6-ditert-butyl-4-methylphenol, 1-3 parts of tributyl phosphate, 2-4 parts of Arabic gum, 1-4 parts of No. 101 gasoline and 2-4 parts of UV-531. The binder is composed of the following raw materials (by weight): 30-35 parts of rosin-modified p-tert-butylphenol resin, 10-15 parts of stillingia oil, 10-14 parts of tung oil, 5-8 parts of long oil alkyd resin, 25-30 parts of oil for printing ink (distillation range 270-290 DEG C), 6-10 parts of linseed oil, 2-5 parts of polyethylene wax, 1-3 parts of nitrocellulose and 0.2-0.5 part of cobalt naphtenate. In the prepared printing ink for pens, the resin in the binder is completely soluble in the oil for printing ink, and resin has good dissolvability in a solvent.

Description

technical field [0001] The invention belongs to the field of ink, in particular to a pen ink. Background technique [0002] Pen ink is the most common kind of ink in daily life, and it is usually filled in the refills of ballpoint pens and carbon pens. At present, the existing ink has poor gloss, insufficient brightness, and slow drying speed. After writing, it needs to be air-dried for a certain period of time. The preservation life of the writing is short, and the writing will fade after a long time. Contents of the invention [0003] The invention provides a pen ink to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A pen ink is composed of the following raw materials in parts by weight: 30-45 parts of activated carbon black, 20-30 parts of colloidal calcium carbonate, 1-3 parts of tetrafluoroisoindolinone, 30-40 parts of binder, linolenic acid 1-4 parts of oil, 2-3 parts of 2-6-di-ter...
