Printing ink for ball-point pen capable of smoothly writing

Abstract

The invention discloses a printing ink for a ball-point pen capable of smoothly writing. The printing ink comprises 5-28% of oil-soluble dye, 5-15% of film forming agent, 30-70% of solvent, 5-20% of dispersant, 2-12% of antioxidant and 12-45% of corrosion inhibitor in percentage by weight. The corrosion inhibitor is a mixture of 40-60% of chromate and 40-60% of nitrite in percentage by weight. The antioxidant and the corrosion inhibitor are added into the printing ink for the ball-point pen, and condensed blocks and crystal crowns are generated in the printing ink for the ball-point pen due to oxidation of brass and interface as well as copper and zinc compositions generated in the liquid. The antioxidant contains substances capable of adsorbing and absorbing surrounding oxygen to effectively prevent oxidation. The antioxidant and the corrosion inhibitor are combined in use to more effectively prevent or inhibit corrosion of copper alloy so as to prevent oxidized substances from blocking the cartridge, so that the printing ink is smooth to output and the pen writes smoothly.

Description

technical field [0001] The invention relates to an ink, in particular to an ink for a ballpoint pen. Background technique [0002] Ball-point pens are deeply loved by consumers because of their clear handwriting, ease of use and low price. Ball-point pen inks are divided into oily inks, water-based inks and neutral inks between the two. Various inks for ball-point pens, for example, the Chinese invention patent application publication specification of 96116415.8 discloses a kind of erasable ink for ball-point pens with application number, the ink is black or blue-black viscose colloid, the weight of its components The percentages are 20-70% of dipping solution, 10-40% of grade A high-pigment carbon black, 0.1-13% of oleic acid, and 5-30% of triphenyl ester solution. The ink is matched with a ballpoint pen equipped with a booster device, which can not only write smoothly and clearly, but also can be erased with an eraser when encountering wrong pens in writing or places that...
